Accelerant used for cabinet tabletop and wall brick joint mixture and preparation method

Abstract

The invention discloses accelerant used for a cabinet tabletop and wall brick joint mixture. The accelerant is prepared, by mass, 2-3 parts of ethylene-vinyl acetate copolymers, 8-12 parts of glass beads, 2-2.4 parts of polydimethylsiloxane, 1-1.5 parts of acrylic resin, 3-6 parts of hydroxypropyl methyl cellulose, 1-1.3 parts of inorganic aluminum salt waterproof agents, 0.5-1.5 parts of magnesium aluminum silicate, 1.5-1.9 parts of RTV organic silica gel and 0.4-0.6 part of hydrophobic fumed silica. Ultrasonic dispersion is performed on ethylene-vinyl acetate copolymers, polydimethylsiloxane and acrylic resin for 0.5-1 h, then hydrophobic fumed silica, inorganic aluminum salt waterproof agents, magnesium aluminum silicate and RTV organic silica gel are added, high-speed stirring and dispersing are performed for 1-1.5 h, finally, glass beads and hydroxypropyl methyl cellulose are added, and then the mixture is slowly cooled to indoor temperature to obtain the accelerant.

Description

technical field [0001] The invention relates to an accelerant and a preparation method for a caulking agent for gaps between cabinet tops and wall tiles. 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 accelerator for a kitchen countertop and wall tile gap filler and a preparation method. [0004] The technical scheme adopted in the present invention is: a kind of accelerant for the gap sealant between the cabinet countertop and the w...
