(54) POLYMERBETON MIXTURE AND METHOD FOR ITS PREPARATION

The invention relates to construction materials, in particular to compositions of polymer concrete mixtures based on furfuropacetone monomer and methods for their preparation. Popimer-concrete mixtures based on furfuro-acetone emots, in particular on the basis of FA monomer, are known. The FA monomer is obtained with a monofuel ratio of furfural and acetone of 1: 1 in the presence of an alkaline catalizer, the monomer of FA contains 5O% monofurfurylideneacetone, and the remainder consists of difurfuriphenecetone with furfurol impurities. The polymeric concrete mixture includes FA monomer, benzine cold stone and mineral filler. The method of preparation of this mixture consists in combining the FA monomer with benzoic sulphonic acid and the subsequent introduction of mineral filler. The closest to the invention in its technical essence and the achieved result is a popimerbeton mixture of the following composition, wt.%: Furfurol acetone resin, FAM8.5-9 monomer, Benzosulfonic acid2204, URFURO13 non-tonic resin FAM is obtained with a ratio of furfural and aceto at 1.5: 1 in the presence of an alkaline catalyst. This monomer contains 3.5% monofurfurylideneacetone. The method of preparation of the polymer concrete mixture consists in mixing the furano-acetone-resin with the benzenesulfonic acid melt and then introducing -. Research Institute of Mineral Plant 2. The disadvantage of these polymer concrete mixtures and methods for their preparation are the relatively low strength properties of the polymer concrete products obtained. The purpose of the invention is to demonstrate the properties of polymer concrete. Objective mixtures, including the displacement of furfurol-acetone resin with a benzenesulfonic acid melt and the subsequent introduction of a mineral filler It consists in heating the dry mixture of powder of furfural acetone resin and mineral filler to 4 ° -45 ° C and combining it with benzene sulfonic acid melt with stirring. Example 1. In a laboratory mixture, equipped with a paddle stirrer and water jacket J, 8% furfuralol 2tone resin 2FA-D containing 87-89% of the difurfurylidene-acetone component in powder form and 90% mineral filler (andesite flour) are loaded. With careful transferring for 20-25 minutes, the mixture is heated to 40-45 ° C, then 2% of the benaol sulfonic acid melt is added, and the mixture is stirred for 3-5 minutes more. The mixture is then discharged into the molds and, after 3-6 hours soaking under normal conditions, subjected to heat treatment for 10-12 hours at.
