Radioresistant joint mixture accelerant for computer room and preparing method

Abstract

The invention discloses a radioresistant joint mixture accelerant for a computer room. The radioresistant joint mixture accelerant is characterized by being prepared from, by mass, 2 parts to 3 parts of ethylene-vinyl acetate copolymers, 8 parts to 12 parts of hole-formed expanded perlite, 2 parts to 2.4 parts of organosilicon flatting agents, 1 part to 1.5 parts of acrylic resin, 3 parts to 6 parts of hydroxypropyl methyl cellulose, 1 part to 1.3 parts of inorganic aluminum salt water-proof agents, 0.5 part to 1.5 parts of magnesium aluminum silicate, 1.5 parts to 1.9 parts of RTV organic silica gel and 5 parts to 8 parts of 400-mesh barite powder. A preparing method includes the steps that the ethylene-vinyl acetate copolymer and the acrylic resin are dispersed through ultrasonic waves for 0.5 h to 1 h, then the organosilicon flatting agents, the inorganic aluminum salt water-proof agents, the magnesium aluminum silicate, the 400-mesh barite powder and the RTV organic silica gel are added, the mixture is rapidly stirred and dispersed for 1 h to 1.5 h, finally the hole-formed expanded perlite and the hydroxypropyl methyl cellulose are added, and the temperature of the mixture is slowly reduced to the indoor temperature.

Description

technical field [0001] The invention relates to a building sealant, in particular to a computer room anti-radiation sealant 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, 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 a computer room anti-radiation caulking accelerator and a preparation method that can effectively absorb computer room radiation and prevent leakage from seams. [0004] The technical solution adopted in the present invention is: a...
