Description

"The invention relates to compositions of polymer concrete mixtures used for the manufacture of chemical resistant materials and structures. A known polymer mixture W comprising, in weight,%: Polyester unsaturated resin 10-16 Cobalt naphthenate 0.6-1.0 Hyperis 0.3-0.5 Selenium 1-2.5 Zinc-2 Mineral filler80-87 The closest to the one we offer is a popimerbeton mixture, including, in wt.%: Unsaturated polyester resin 10-16 Cobalt naphthenate 0.8-1.0 Hyperis0.3-0.5 A mixture of vanadic acid and tin chloride in the proportions ii 1: 1 2-4 Diabase flour 25.6-36.1 Graphite45 , 7-57.1 Failure. known mixtures is the relatively low resistance of polymer concrete in a 15% growth solution of NaOH after soaking for 6 months. The purpose of the invention is to increase one hundred. polymer concrete bones in a 15% NaOH solution after six months of exposure. This goal is achieved by the fact that polymer concrete mixture, a mixture of unsaturated polyester resin, cobalt naphthenate, a hardening accelerator and a quartz filler contain the triarnlamidazolyl dimer and dimedone as the accelerator, in the following ratio,% by amount, and there is no case, and there is no need to put in the same ratio,% by amount, it is not enough to set, it’s not enough to set, it’s not enough to set, it’s not enough to set, it’s not enough 11-15 Cobalt naphthenate 1.0-1.4 Dimer triaripamidayolila0, 3-0,6 Dimedone1,5-2,5 Quartz fillerOtherly 0 formula of triarilamidazolyl dimer, Dimer used photochromic structure Dimedone structure (5,5-dimethylcyclohexane-1, 3 ) SN / SG-™ Technical Conditions for Dimedone TU 6-09-4690-78 ChDA. The full mix concrete is prepared as follows. The polyester resin and cobalt naphthenate are mixed, the dimer of triarylamidazole, dimedone and quartz filler are added to the mixture, mixed thoroughly until a homogeneous mass is obtained, and samples are formed from the latter, which solidify for 8 hours. The compositions of polyester polymer concrete mixtures, wt.%) Are presented in table. one. . Compounds 1-3 are known mixtures, 4-6 are proposed. . Test specimens were prepared in the form of prisms with a size of 4-4-16 cm. The results of testing concrete samples of the proposed mixture are presented in Table 2. The proposed polymer concrete mixture can be used for coatings resistant to NaOH in the protection of metal, reinforced concrete and concrete structures.
