Description

The invention relates to the field of building materials, namely, polymer concrete mixtures used for the manufacture of corrosion-resistant structures. A polymer-concrete mixture is known, containing furfurol-acetone monomer, benzenesulfonic acid, crushed stone, sandstone and microfiller Ij. However, the physicomechanical properties of a known mixture are not high enough, which limits its scope. The closest to the invention to the technical essence and the achieved result is a polymer concrete mixture of the composition, wt.%: Furfurolac monomer 25.4-27.4 Benzosulfonic acid 5.6-7.6 Plasticizer (ester of MULTI-BASIC acids and monohydric alcohols) 1 , 06-1,32 Mineral fillersExtra The esters of polybasic acids contained in the polymer mixture and aliphatic alcohols also insufficiently increase the physical and mechanical properties of the polymer concrete. In addition, this penetration is unstable, since this plasticizer does not chemically bind with the macromolecules of furfurol acetone monomer and is able to migrate to the surface of the product, therefore the physico-mechanical, indicators of the cured polymer concrete mixture decrease. The aim of the invention is to increase the strength characteristics of the polymer concrete. This is achieved by the fact that a polymer concrete mixture including furfuro-acetone monomer, benzenesulfonic acid, plasticizer, crushed stone, pvsok and micro-filler contains as a plasticizer a mixture of N-oxymethylstearylamide and condensation of ethylene oxide with fatty acids, VZYYYY, you will need to be in the world, but you are there to be in the way of the world to get to be in the same, if you are there to be in the world, but you are there to be in the world, but not enough to have to control, you are going to be in the world, and you will need to be in the world, but you will need to be in the world, but you will need to be in the world, but you will need to be in the world, but you are there to be in the world, but you will need to be in the world, if you are going to be in the same, if you are to be in the world, you are going to be in the world, and you will have to be in the same, if you are going to be in the world if you are going to be in the world if you are going to be able to use it). 1-, in the following ratio of components, wt.% I Furfurol-acetone monomer 6.0-12.0 Benzenesulfonic acid 1 g 5-3.0 Mixture of N-oxymethylstearyl amide and condensation products

A mixture of N-oxymethylstearyl amide and condensation products of ethylene oxide with fatty acids is produced according to STU JA12-10-134-61 and has the trade name Drug-AM. A mixture of N-oxymethylstearyl amide and condensation products of ethylene oxide with lactic acids, in whose molecules there are unpaired electrons, is able to shield some of the active centers of furfurol-acetone monomer and chemically bind to them during polycondensation, as a result of which it is impossible to migrate on the surface of polymer concrete. only the physicomechanical indicators of hardened polymer concrete are observed.

The technology for making polymer mixture is as follows.

A polymer mastic consisting of furfurol-acetone monomer, benzosulphonic acid melt, micro-filler and plasticizer is prepared in the concrete mixer. Polymer mastic is mixed for 1-2 minutes, and then a pre-mixed mixture of medium and coarse aggregates is introduced into it. Polymer concrete, mix the mixture for 3 minutes. Thus prepared polymer mixture is placed in the form.

Exemplary formulations of the proposed polymer concrete and the properties of the polymer concrete obtained on their basis are given in table. 1 and 2 ..

As can be seen from the test results, the proposed composition of the polymer-concrete mixture as compared with the known one, with a certain increase in the compressive strength, allows a considerable increase in the flexural strength.
