Description

(54) POLYNER CONCRETE MIXTURE

The invention relates to polymeric construction materials, and to compositions of polymer concrete mixtures based on furfurol-acetone monomer. The polymer concrete mixture 1 is known, which includes the following ingredients, wt%: Furfurol-acetone monomer8 Benzene sulfonic acid2, 4 The bottoms of the rectification of raw benzene L Aggregates70 Fillers5 6 Polymer concrete of this composition has sufficient strength and chemical resistance, but relatively low drag resistance, but relatively low drag, but it has relatively low resistance and chemical resistance, but relatively low drag, but it has a relatively low resistance, but it has a relatively low resistance, but it has relatively low resistance and chemical resistance; The closest to the invention to the technical essence and the achieved result is polymer concrete mixture 2, which includes furfurol acetone monomer, benzenesulfonic acid, acid-resistant crushed stone, expanded clay sand and waste molding of metallurgical production of the following composition, wt. $: Polymerized oligomers 0,4-1,2 Chlorides aluminum and ammonium 22.5-32.7 Iron oxide 0.6-1.0 Carbon black 0.2-0.4 Quartz sand The rest is the following ratio of components, wt%: Furfurol-acetone monomer8-15 Benzene sulphonic acid, 6- 3 kis traction rubble, 40-50

The disadvantages of this mixture are high water and acid resistance, high cracking capacity, low strength and adhesion. ,

The purpose of the invention is to increase the adm ™ of ezii, WATER, acid resistance, resistance to corrosion and mechanical strength.

The goal is achieved by the fact that polymer concrete mix for manufacturing heat treated products, including furfurol-acetone monomer, benzenesulfonic acid, acid-resistant crushed stone, expanded clay sand and waste molding of metallurgical production, additionally contains a polyisocyanate in the following ratio of components; May.%:

and a filler as a result of interaction with both active sites on the surface itself and with water and other polar compounds,

adsorbed on it. By

this improves the adhesion between the aggregate, filler, and polymer binder. This leads to an increase in mechanical strength and crack resistance.

As a polyisocyanate, it is recommended to use a brand K of polyisocyanate (TU 6.03-29-7-77). The polymer concrete preparation technology includes: preparation of components, dosing of components, combination of a polyisocyanate solution with a filler ;, a filler and molding waste of metallurgical production, combination with furfurolacetone / H and a measure, and the introduction of benzenesulfate acid.

Melting or dissolving benzenesulfonic acid, preparation of a polyisocyanato solution is included in the preparation of the components. Dosing can be both by volume and by weight. The mixing of the constituents is carried out in standard concrete or mortar mixers. The total mixing time is 10–15 min. The resulting mixture is used to form articles that harden at 18 + 3 ° C for an hour and then undergo heat treatment at 80–90 ° C for 10–12 h.

The compositions of the proposed polymer mixture and their properties are presented respectively in Table. 1 and 2.
