Mineral

Filler Else However, the mixture is characterized by insufficient surface hardness and wear resistance of the resulting coatings.

The aim of the invention is to increase the surface hardness and wear resistance of the coating.

The goal is achieved by the fact that the polymer concrete mixture, which incorporates polyester acrylate resin, cobalt naphthenate, hyperis, thiokol, carbon black, modified aerosil and mineral filler, contains 20 modified aerosil methylvinyl arosyl in the following ratio of components, May. %: Polyether acrylate resin8-12 Cobalt naphthenate 0.2-0, Jt Hyperis0.1-0.2 Thiokol0, Soot0, 5 Methylvinylaerosil 0.1-0.2 Mineral filler Else The polyester acrylate resins used are oligomers MGF-9 (Ty-6-01-ii50-76) and TGM-3 (TU 6-16-Y 5-B9). It is envisaged to use about P. brand. Thiokol of brand P is a liquid thiokol obtained from di - (. (L-chloroethyl) -formal, 1,2,3, -trichloropropane and sodium tetrasulfide) and is treated with a polymer (5: Ethyleneoxy) - methane containing disulfide bonds in the molecule, and at the ends of the polymer chain reactive sulfhydryl groups - "SH. The structure of liquid thiokols, depending on their molecular weight, is represented by the following formula HS- (CX, H -O-CIVO- C H -5-5). And-C H "-O-CHi-OC H -SH, where. The average molecular weight of the thiokol is 000. The viscosity at 25 ° C is 301-500 Pz. And Hyperiase hardener (MRTU 38-2-5-66), Cobalt naphthenate curing accelerator (STU 30-1A-95-64). Thiokol and carbon black are introduced into the polymer concrete mix in the form of a sealing paste, produced by ZOM; It is a homogeneous mixture of 23% by weight of lamp black and 77% by weight of P. brand P. Methylvinyl Aerosil is a modification of Aerosyl methyl vinyl dichlorosilane and can be represented by the formula CjHj CHrCHfiI., O-Si It 99 84 As a mineral the filler is preferably a mixture consisting of:, weight. %: andesitic flour 20; quartz sand 20; granite crushed stone of fraction 5-25. mm 60. Resins MGF-9 and TGM-3 can be used as a binder. The method of preparation of the mixture consists in preparing a mixture of thiokol, carbon black (lamp), and combining it, for example, coL Y-dimethacrylate (dUyt-triethylene glycol) phthalate. then hyperis and methylvinyl arylryl are introduced. After thorough mixing, the cobalt naphthenate is added to the mixture, followed by the mineral filler, and all components are mixed again until the filler is completely wetted by the binder. Curing of the prepared polymer mixtures is carried out at room temperature. Full cure time 14 days. The proposed polymer concrete compositions and the prototype composition were tested under laboratory conditions. The composition of the polymer compositions are presented in table. 1. Physical and mechanical properties of polymer concrete are given in table. 2. Chemical resistance of polymer concrete is indicated on the table. 3. According to the obtained test results, it can be seen that the proposed composition of polymer concrete, as compared with the prototype, has more than 2 times higher wear resistance and approximately 1.5 times higher surface hardness. The coefficients of resistance in various solutions of corrosive media, which are the ratio of the compressive strength of the samples after exposure to the solution to the original strength, as well as the mechanical strength of the proposed formulations are at the level of the coefficients of resistance of the prototype.
