Weather resistance stabilizing agent of crack filler and preparation method

Abstract

The invention discloses a weather resistance stabilizing agent of crack filler and a preparation method. The weather resistance stabilizing agent of the crack filler is prepared from, by mass, 2-3 parts of ethylene-vinyl acetate copolymer, 8-12 parts of vitrified micro bubbles, 1-1.5 parts of acrylic resin, 3-6 parts of hydroxypropyl methyl cellulose, 1-1.3 parts of inorganic aluminum salt water-proofing agents, 0.5-1.5 parts of magnesium aluminium silicate and 1.5-1.9 parts of 107 organic silica gel. Ultrasonic dispersion is conducted on the ethylene-vinyl acetate copolymer and the acrylic resin for 0.5-1 hour, then the inorganic aluminum salt water-proofing agents, the magnesium aluminium silicate and the 107 organic silica gel are added, high-speed stirring and dispersion are conducted for 1-1.5 hours, finally the vitrified micro bubbles and the hydroxypropyl methyl cellulose are added, the mixture is slowly cooled to room temperature, and the weather resistance stabilizing agent of the crack filler is obtained.

Description

technical field [0001] The invention relates to a construction joint filler, in particular to a joint sealant weather resistance stabilizer and a preparation method. Background technique [0002] Because the caulking agent can perfectly repair the cracks or damages on the ground surface, and it can also be prepared in rich colors, it is more and more popular among customers. However, most of the existing joint fillers are made of cement, together with additives commonly used in cement, which have the disadvantages of environmental resistance and environmental protection, and have great limitations in application occasions, safe use, and long life. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides an environment-resistant and environment-friendly sealant weather resistance stabilizer and a preparation method. [0004] The technical scheme adopted in the present invention is: a weather-resistant stabilizer for caulking ag...
