Description

454) POLYMERBETON MIXTURE

The invention relates to building materials, in particular, to the composition of polymer-concrete mixtures based on polyester resins and can be used for constructing protective floor coverings, making structures, parts of apparatuses, etc. The polymer concrete mix l is known, containing ingredients, weight. Unsaturated Polyester Resin8, 0-9.3 Cobalt Naphthenate 0.6-0.7 Isopropylbenzene hydroperoxide, 15-0.2 Macrodiisocyanate, 5-1.2 Diabazov 8.0-9.25 Flour 22.7-26.2 Sand The rest of the Crushed Nanbene closer to the proposed technical essence and the achieved result is a slip on the polymer concrete mix 2, including, wt.%: Non-saturated polyester 8.0-9.3 resin Naphthenate co0, 6-0.8 balt Isopropylben hydroperoxide0, 15-0.2 Macrodiiso0 ash, 5-1.2 cyanate 8.0-9.25 Diabase flour 22.7-26.2 Methylvinyl Aero sand 1, 0-2.0 strength Else. Crushed stone The disadvantage of the known mixtures vts is low specific viscosity. The purpose of the invention is to increase the viscosity. This goal is achieved by a polymer-concrete mixture, including polyester resin, cobalt tenate, ropylbenzene hydroperoxide, macrodiisocyanate, lvinylerosil, diabase flour, and crushed stone, and i-dimethymete, and i-dimethymete, and I-dimethymete, and I and dymethymete, and I and I, and I-dimethymete, and I and dymethyme, and I and dymethyme;

The preparation of the mixture compositions is carried out as follows.

The unsaturated polyester resin; pN-1 is combined with tri (oxyethylene) pJ, a screener on pec-rastera (TGM-3 resin). After that, cobalt naphthenate, isopropylbenzene hydroperoxide, macrodiisocyanate, methyl methylacetylene and pyroxyfluorine-vinylene-vinylene-vinylerene, pyroxylate, and peptocrylate are combined. sand and crushed stone. After adding all the components, mixing is continued until all the fillers are wetted by CMonofi.

In tab. 1 presents the proposed composition of polymer mixtures.

The mixtures are cured in the temperature range from to, the curing time is 26 to 55 hours, the polymer concrete acquires maximum strength after 10 to 30 days.

The physicomechanical properties of the compositions of polymer mixtures are given in Table 2, where compositions 1-3 are suggested, gaems, 4 is known.
