Abstract

The invention discloses a heatproof antifreezing modified adhesive for a cement reinforcer. Raw materials of the adhesive comprise polyurethane, vinyl acetate, formaldehyde, urea, methenamine, hydrochloric acid, phosphoric acid, disodium ethylene diamine tetraacetate, polyxyethylated alkylphenol, aluminium nitrate, aluminium chloride, sodium hydroxide, sodium bicarbonate, acrylic acid, 2-vinyl crotonate, polyacrylate, toluene diisocyanate, polyhydroxy fatty acid, dibutyl phthalate, N-methylolacrylamide, OP-10, silica sol, ammonium persulfate, octanol, glycol, A antifreezing reinforcing filler,A heatproof tackifier and deionized water. The invention also brings forward a preparation method of the above heatproof antifreezing modified adhesive for a cement reinforcer. The prepared modifiedadhesive is used for preparation of a cement reinforcer, and has excellent heatproof antifreezing properties.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a heat-resistant and frost-resistant modified adhesive used as a cement reinforcing agent and a preparation method thereof. Background technique [0002] Adhesive is a water-based emulsion glue developed in the 1950s to make up for the lack of animal glue. It can be used for mortise and tenon joints, gluing of fine wood boards, repair of veneers, secondary processing of wood-based panels; it can also be used for bonding of porous materials such as paper, paper tubes, cloth, leather, and ceramics. The consumption of adhesives in our country is now second only to urea-formaldehyde resin. Adhesives have disadvantages such as poor cold resistance, poor mechanical properties, water resistance, and poor impact resistance. When used to prepare cement reinforcing agent, its cold resistance and heat resistance cannot meet the needs of actual use, so it is urgent to design a heat-resis...
