    A method of producing laminar structures, preferably consisting of fibreglass-reinforced polyester, which are free of air-pockets and pores, by spraying layers of the plastics and reinforcement fibres at a partial vacuum. The method may be carried out by an industrial robot. An airtight surface layer may be sprayed onto the laminate, whereby any pores or air-pockets collapse when the laminate is exposed to air at atmospheric pressure.

    sl The invention relates to a process for the production of reinforced plastics based on glass fiber napole and polyester resins. Methods are known for the manufacture of reinforced plastics by applying raw materials to the walls of a mold by spraying or rubber bag methods (under pressure and in vacuum) lj. However, in the implementation of these methods, the sputtering of the initial materials occurs at atmospheric pressure. One of the problems inherent in spraying methods — deposition carried out in the surrounding atmosphere is the fact that a significant amount of air enters the laminate. As a result, long and laborious operations are required for dl. making the laminate more uniform. Despite subsequent processing in the laminated material, an extra amount of air remains and this causes moisture to penetrate into the laminated material and weaken its chemical and mechanical strength. The closest to the invention in its technical essence and effect is the production of fiberglass-reinforced synthetic laminate resins with a surface coating of polyester. Sp. comp provides for the manufacture of the base material in various ways and, in particular, by vacuuming. a lot of molding, after which the base is removed from the device for vacuum forming, and the subsequent deposition process of the polyester layer by spraying is carried out at an atmospheric pressure of 2 °. The disadvantage of this method is that during the manufacturing process air enters the material, which results in the need to further roll the material. The step of rolling the material does not affect the mechanical strength of the final composite material, as well as the distribution of fiberglass in it, nbtikanbKy, when rolling, the fibers move to the lower part of the combined material. Eliminating the operation of rolling, which, in addition to undesirable effects on the structure of the final material, is in itself a long-lasting and, accordingly, expensive process, is one of the objectives of the invention. . This goal is achieved by the fact that according to the method of producing reinforced plastics on the glass fiber-reinforced filler and polyester binder by spraying a filler and a binder onto the walls, followed by spraying. carried out in a vacuum chamber where the pressure is 5-25% of atmospheric. By carrying out the process under vacuum conditions and the presence of a surface layer preventing air penetration, the shells and bubbles formed during the preparation of the product are destroyed as soon as the laminate is exposed to atmospheric air after the laminate is produced. The method can be carried out with the help of a fully automated device, which in comparison with known working technologies leads to a reduction in production time by about 10-25% of the time required for working with traditional technologies. Along with improved economic indicators, the implementation of the proposed method The following additional benefits: A laminated material consisting of polyester and fiberglass is more competitive in areas where, for cost reasons, it is until now, he was unable to compete. Improving the quality of the resulting laminate is due to improved mechanical-. properties and resistance to water absorption. When a layered structure is obtained with the aid of automatic devices or by controlled spraying under partial vacuum, the laminate becomes satisfactorily free from air and pores. This, for example, reduces the cost of subsequent ancillary treatments currently required. Moreover, all manual work is eliminated, since the process can be completely carried out with the help of automatic devices in sealed chambers under partial vacuum (95%). In terms of the environment, the method is more advantageous because it eliminates the need for direct contact of workers. with the production device (installation) in which the laminate is manufactured. The application of the proposed method improves the casting productivity of the mold by about 75-150%, since the homogenization operation is excluded. In addition, the method does not depend on the gel time, i.e. curing can be initiated immediately after applying the material to the mold. However, the gelation time must be set in such a way that it starts only at atmospheric pressure,. .: ..- Since it is possible to reduce the number of used molds due to reduced application time, the producer costs for molds are reduced, in addition to this, the production area is significantly reduced. In practice, an enterprise for the production of laminated material can reduce its production area by 50% or increase its productivity COOT respectively at the same production areas. In addition, the technology offered by the platform can be used. in the manufacture of keels for boats .. All layered materials mrut. be- made identical, resulting in a layered thickness. ; material more uniform .. up to the present; time layered ma. The materials obtained by conventional processing methods vary significantly. Fig. 1 shows a device for carrying out the proposed
    In the side view, in FIG. 2 - the same, top view; FIG. 3 shows a laminated material from glass-fiber reinforced polyester; in front of 5 by exposure to atmospheric pressure, a section; in fig. 4 - the same. after exposure to atmospheric pressure,
    The installation, for implementing 10 of the method (Fig. 1), consists of three 6t separate chambers t -, - 3, / interconnected through 1SH-5S 4-7, Chambers t-3, when operated, are under partial vacuum up to 95%. Chambers are sized to allow them to hold the voltage of a partial vacuum. 111) The process of reinforced plastics is carried out in chamber 2. A spraying device 8 equipped with an industrial robot 9 is mounted on an overhead crane 10 inside chamber 2, and the gates 4-7 of chambers 1-3 are open and closed when the pressure is equal on either side of the locks 4-7. B. Chamber 2 is provided with a passage opening t1 to make it possible to correct any production failure. Production by the proposed method begins with preparation of the mold by placing it inside the entrance of chamber 1, at which time the liner 4 is closed and chamber 1 is pumped out to create a partial vacuum. Due to the fact that the central chamber 2 is constantly maintained, the partial vacuum, the partition of the gateway 5, which is intermediate between the entrance to the chamber 1 and the robot 9, can be opened. The molds then automatically move and begin the spraying operation. Before the form reaches the exit of the gateway 6, the chamber 3 is evacuated to create a residual vacuum, after which the gateway 6 between chambers 2 and 3 opens and the form moves into the last chamber 3. Then the gateway 6 is closed and injected into the air at .. pressure of the world. The gateway 7 is opened and the form with the laminate material is removed for further processing. The proposed method is as follows. When (Fig. 3) polyester 12 fiberglass 13 is applied to the mold 14 under partial vacuum in amer, small bubbles 15 at 90% remain a partial vacuum laminate. The air-tight layer 16 renders any topcoats superfluous since it becomes completely tacky after curing. The purpose of this layer is to prevent air from penetrating into the laminate, where air enters (shown by stitching in Fig. 4) into chamber 3, puffs 15 that are in the laminate under partial vacuum. completely, resulting in a laminate,. released from air 4), 1 The proposed method ensures obtaining a high-quality, high-quality homogeneous laminate without air inclusions, because by applying an air-tight surface layer under vacuum conditions, the air does not penetrate into the laminate, the pores and bubbles formed during the process immediately settle after the laminate is exposed to air at atmospheric pressure. Due to the creation of the Boskr airtight layer, the subsequent rolling is unnecessary.
