Environment-friendly additive of crack filler and preparation method
The invention discloses an environment-friendly additive of crack filler and a preparation method. The environment-friendly additive of the crack filler is characterized by being prepared from, by mass, 2-3 parts of ethylene-vinyl acetate copolymer, 8-12 parts of vitrified micro bubbles, 2-2.4 parts of gas phase silicon dioxide, 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 ferrous sulfate, 1.5-1.9 parts of RTV organic silica gel and 0.4-0.6 part of antioxygen 1076. Ultrasonic dispersion is conducted on the ethylene-vinyl acetate copolymer and the acrylic resin for 0.5-1 hour, then the gas phase silicon dioxide, the inorganic aluminum salt water-proofing agents, magnesium aluminium silicate, the antioxygen 1076 and the RTV organic silica gel are added, high-speed stirring and dispersion is 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 environment-friendly additive of the crack filler is obtained.
