Abstract

The invention discloses a spraying film waterproof coating component B prolonging the self polymerization time and a preparation method thereof. The raw materials include, by weight: 100 parts of magnesium acrylate monomer solution, 0 to 5 parts of acidity regulator, 0 to 5 parts of alkaline regulator, 5 to 20 parts of white carbon black and 5 to 20 parts of calcium carbonate. The invention further discloses a preparation method of the spraying film waterproof coating component B prolonging the self polymerization time; the method includes adding the 0 to 5 parts of acidity regulator, 0 to 5 parts of alkaline regulator, 5 to 20 parts of white carbon black and 5 to 20 parts of calcium carbonate into the 100 parts of magnesium acrylate monomer solution, and stirring through a high speed dispersion machine. According to the spraying film waterproof coating component B, the time for self polymerization is prolonged by 180 minutes after oxidizing agents are added, the self polymerization time is prolonged greatly, and the situations of material loss and construction period delay since the self polymerization is performed in a short time after oxidant is added are eliminated.

Description

technical field [0001] The present invention relates to a spray film waterproofing material, specifically a coating that utilizes two kinds of paints, A component and B component, to form a waterproof spray film, especially relates to the formula of the B component waterproof spray film material and its The preparation method belongs to the technical field of waterproof paint. Background technique [0002] In tunnels and other underground projects of basic engineering facilities, the requirements for anti-leakage water are very high. The waterproof measures currently used are usually by spraying film construction, that is, spraying liquid paint on the wall or wall surface that needs to be waterproofed. After the paint dries, it will solidify to form a waterproof film. When the waterproof film is formed, the existing technology is to divide the waterproof spray film material into two parts, namely A component and B component, and the two parts of paint are separately packed,...
