    1491698 Laminated wood materials BASF AG 13 Dec 1974 [15 Dec 1973] 53919/74 Heading B5N [Also in Division B2] A curable cladding for wood materials comprises a support web (particularly of paper or woven or non-woven fabric) impregnated with a curable aminoplast or phenoplast binder and coated on one side with a curable polyester resin coating comprising a cross-linker and a polyester resin mixture consisting of 20-98% by weight of non-crystallizable unsaturated polyester and 80-2% by weight of crystalline unsaturated polyester. The binder may be an aqueous ureaformaldehyde; phenol-formaldehyde or mixed urea-melamine-formaldehyde condensate. Various polyesters are specified and may be applied by pouring, rolling, spraying or knife-coating, often as solutions in the cross-linkable monomer. The cross-linker may be styrene, chloro-styrene, methyl methacrylate, butyl acrylate, divinylbenzene or diallyl phthalate and diallyl phthalate prepolymer may itself constitute a part of the polyester resin mixture. Both the binder and polyester mixture may contain fillers and the latter may also contain an alkaline earth metal oxide or hydroxide as thickener. The claddings may be bonded to chipboard or fibreboard by means of heat and pressure, optionally with the use of an adhesive.

    (54) COMPOSITION AND METHOD FOR ITS TREATMENT The invention relates to the manufacture of plastics, in particular, to the development of a lacquer composition based on polyester resins. A known composition for producing a coating on a substrate treated with amino or phenolic resin (paper, wood) based on polyester resins, in particular, non-crystallizing, and a method for processing it. The resulting coatings have insufficient gloss, strength and adhesion 1. The purpose of the invention is to obtain a composition for a coating characterized by high adhesion to the substrate, strength, improved gloss, as well as a varnish coating from such a composition more simple in comparison with the known method. Thus, high quality lacquer shakri is obtained without prior polishing and varnishing, but directly during pressing (curing of the polyester composition), for example, at a pressure of 1-10 kgf / cm, for 20-120 s and at a temperature of 150-170 ° C. According to The invention uses a mixture of non-crystallizing and crystallizing polyester resin at room temperature in a ratio of 20-98: 2-80 for preparing the composition, and the coating of such a composition is cured at 5O-120 ° C. Pre-soaking of substrates is carried out in a known manner. The viscosity of impregnating solutions from an aminoplast or phenoloplastic resin, containing typically 45-55% solids, is usually 3065 cP. The reactivity of the resin impregnation solutions can be adjusted with hardeners. In addition, pacTBCq may contain a wetting agent to improve paper penetration, as well as, for example, antifoam agents. After impregnation, drying is carried out. According to the invention, the pre-impregnated and dried substrate is coated with a flowable mixture of unsaturated polyester with a crystalline insoluble polyester. Such compositions typically contain, in addition to binding, a structuring agent, catalysts, and other targeted additives. The composition is applied by casting, casting, spraying, squeezing and so on. Its consumption varies depending on the coating technique. However, in comparison with the amount of aminoplast HJm phenol resin used for impregnation, the amount of the polyester mixture is lower and only in rare cases is the same. It is advantageously between 20 and 100% of the resin mixture. Sequence} 1 is used in an amount of, for example, from 50 to 180% by weight of the paper. By adding oxides or hydroxides of metals, in particular magnesium oxide, calcium oxide, and equivalent hydroxides to a polyester blend, the polyester mixtures can be thickened, if necessary, in addition to obtaining almost non-tacky gels that can be preserved without noticeable changes for a long time and subjected to crosslinking only at elevated temperature. By adding appropriate agents, they can also be preliminary stitched by means of additional ionic polymerization. Apply on the substrate a copolyester resin in a solvent or c. solvent mixtures optional. However, in order to obtain well-curable coatings without tackiness, it is advisable to add to the composition a reactive monomer "forming a major amount of solvent, as well as an additionally light solvent, removing the latter after coating by heat treatment. Preparation of various compositions from the resin resin company: a) 400 parts of a 60% solution in acetone of an unpleasant complex mixture with a softening temperature of 75-80 derived from m-shainoic acid, teraphthalic acid dimethyl ether and propyl glycol -1.2 the molar ratio of it is 2 is the acid number of about 20), mixed with 103 parts of the prepolymer digsyl-phthalate and homogenized by stirring for 24 hours. test temperature 6% t-butyl peroctoate is added to the mixture. After settling, a precipitate is deposited, however, it is easily agitated. Blending 80 parts of a 50% solution of diallyl phthalate prepolymer in monomeric dihydroyl phthalate and 400 parts of a 60% solution of unsaturated polyester in a mixture, and p.a, 24 h is stirred at ksmattny temperature. Ie 9t mixture (viscosity S6 dyn.s) at settling precipitates. To the mixture of resins, stirring, add 2.5% psrcccooled, partially cross-linked bold polyester. Before coating a layered paper, the mixture is shaken vigorously with the addition of 61 t-butyl peroctoate and becomes homogeneous. c) The unsaturated polyester resin consists of a 60% solution in the styrene of the unsaturated polyester (of maleic acid, c-phthalphthalic acid, and propylene glycol -1, 2 in a molar ratio of 2: 1: 3). To this stabilized 0.01% hydroquinone (acid number about 33). Before coating the layered material, add 6% tert-butyl peroctoate j g) in 3000 parts of the unsaturated polyester resin described at room temperature, add 35 b. including magnesium oxide, then kept at a viscosity of about 109,000 cP until cooling capacity reaches 20 ° C. Before layering, 6% tert-butyl octoate is added. PRI im p As non-crystalline resins, a resin is used, for example, resin A is cstSilized with hydroquinone (0.01%) 66% styrene solution of unsaturated polyacrylate from maleic acid, orthophthalic acid and 1polyglycol -1.2 in a molar ratio of 21%, 21, a 21% is 21, and is a 21%, 21, and is a 21%, 21, 21, and 21, 21%, and 1popyliglycol -1.2 in a molar ratio of 21%, and a 21% is 21, and is a 21%, 21, and is a 21%, 21%, 21, 21%, and 1popyliglycol -1.2 in a molar ratio of 21%, and a 21% is 21, and is a 21%; The acidic number of polyester 50} resin B is that the product is stabilized with chroroquinone (0.01%) and a 5% styrene solution of an unsaturated malefacin polyether and propylene glycol -1.2 at a molar ratio of 1: 1. The acid number of the resin is 18. 10; Istaplizuyu1weis polyester. smAlL is, for example, (ep, crystalline, non-apical polyester, containing fumaric and adspiic acids and butanediop-1,4 in a molar ratio of 4: 1: 5. The acid number of polyether is 20 ° C, 112 ° C. K The x4-position, according to the invention, DSL1 coatings are obtained, for example, by following. Stacks (lysine hydroquinonogl (0.135 parts by weight) mixture of 485 parts of polyester resin A, 650 hours of polyester resin 6, 484 parts of crystallizing polyester and 380 hours of styrene and heat transfer fluids into the atmosphere of a gas up to, after which the resulting rgi: the creature is slowly cooled to room temperature. & white white suspension 1000 cP.
