Joint mixture air-purifying promoter and preparation method

Abstract

The invention discloses a joint mixture air-purifying promoter. The joint mixture air-purifying promoter is characterized by being prepared from, by mass, 2-3 parts of ethylene-vinyl acetate copolymer, 8-12 parts of glazed hollow beads, 2-2.4 parts of fumed silica, 1-1.5 parts of acrylic resin, 3-6 parts of hydroxypropyl methyl cellulose, 1-1.3 parts of inorganic aluminum salt water-proofing agent, 0.5-1.5 parts of aluminium-magnesium silicate, 5-8 parts of white bamboo charcoal and 1.5-1.9 parts of RTV organic silica gel. After ultrasonic dispersion is conducted on ethylene-vinyl acetate copolymer and acrylic resin for 0.5-1 h, fumed silica, inorganic aluminum salt water-proofing agent, aluminium-magnesium silicate and RTV organic silica gel are added and stirred and dispersed at a high speed for 1-1.5 h, and finally white bamboo charcoal, glazed hollow beads and hydroxypropyl methyl cellulose are added and slowly cooled to the room temperature.

Description

technical field [0001] The invention relates to a caulking agent air purifying accelerator 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 such as waterproof, water-repellent, fire-resistant, and cold-resistant. There are defects in combined use, and they 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 a caulking agent air purifying accelerator capable of promoting air purification and a preparation method. [0004] The technical solution adopted in the present invention is: a caulking agent purifying air promoter, comprising 2-3 parts of ethylene-v...
