    专利说明:

    This invention relates to an anti-abrasive and chemically anticorrosive material used in mechanical engineering and a method for its preparation. In the industry, where the transportation of liquid with highly erosive suspensions, the elements that are in contact with them, such as pumps, flotation machines, agitators, etc., wear out very quickly, sometimes after a few hours of operation, which makes them expensive to operate. devices. An increase in the operating time of these parts is usually achieved by capping. But this method cannot be applied in all cases due to the difficulty of the rubber technology and the low mechanical resistance of the rubber. Materials are known that are used for the same purpose, based on epoxy resins in combination with different anti-abrasive components. These materials have drawbacks; I conclude with low mechanical resistance. At the same time, the known compositions present difficulties associated with fast PCICTOM viscosity, which makes the casting operation difficult in matrices. The closest to the proposed technical essence and the achieved result is the composition of anti-abrasive and anti-corrosion. material, where metal oxide and silicon carbide are used as filler l. The disadvantages of the known composition are its low mechanical strength as well as porosity, which makes them unsuitable for casting or coating wear elements for equipment operating in highly corrosive and erosive environments or transporting such suspensions. The purpose of the invention is to increase the anti-abrasive and anti-corrosion. composition resistance. The goal is achieved by the fact that the anti-abrasive and anti-corrosion material consisting of an alumina-based filler and silicon carbide additionally contains glass fiber and is based on two types of epichlorohydrin-based epoxy resins and 2,2-bis-para-hydroxy diphenylpropane from molecules weight of 350-1400 ,. taken in a 1: 2 ratio with a hardener in the form of phthalic anhydride, in the following ratio of components / wt.%: Filler 79.5-80 Glass fiber 0, 5-5 V permeable 15-20 It is advisable that the filler contain aluminum oxide and silicon carbide in the ratio of 1: 2. Such a material can be obtained by means of a different method, according to which a resin is first prepared by mixing two types of resins at 120 ° C, which is mixed with glass fiber, and then a pre-moistened filler is added with a solution in the acetone resin and after homogeneity, the material is thermally treated with for 1-5 hours. The method of obtaining the anti-abrasive and anti-corrosion material consists in preparing a binding substance, mixing these two types of resins and adding a strengthening agent in the first step. In the next step, the filler pre-moistened with a solution in acetone is added, and the material is thermally treated for 1-5 hours at. Example. To prepare fortified and pre-moistened anti-abrasive filler, 333 g of A12Oz are mixed with a normal particle size between 0.3-0.6 mm, 660 g Sic with a normal particle size of 0.6-1 mm and 5 g glass fiber 2 -5 mm. The mixture is pre-moistened with .200 cm of a solution of 7% dissolved in acetone with continuous mixing, then left to evaporate the solvent. Removal of the solvent can be carried out by heating. i .. The wafer is obtained by mixing two epoxy resins (both based on epichlorohydrin and 2,2-bis-parahydroxyphenylpropane) in a 1: 2 weight ratio with varying degrees of polycondensation, with molecular weights 350-1400, adding phthalic anhydride as a fortifier. The mixing of these two resins is carried out with, then phthalic anhydride is added by shaking until complete dissolution. To prepare the anti-abrasive fabric, the pre-moistened filler is heated by repeated mixing at and 170 g is added to the tare material heated at 120 ° C, continuing the slow mixing of the material until homogenization. After homogenization, the material is poured into preheated matrices at 130s, which are thermally treated for 15 hours, then the voltage is removed from the part. The proposed material due to its great corrosion resistance and mechanical resistance can be used in mechanical engineering dd
