Spray film waterproof material capable of preventing splashing and its preparation and use method

Abstract

The invention discloses a spraying-film waterproof material capable of preventing splashing, and a preparation and application method thereof. The spraying-film waterproof material is prepared from the following raw materials in parts by weight: 100 parts of magnesium acrylate monomer solution, 2-10 parts of polyvinyl alcohol solution, 2-20 parts of kaolin, 2-20 parts of silica white and 2-20 parts of calcium carbonate. By utilizing the technical characteristics of adhesiveness in the polyvinyl alcohol solution and compatibility in the magnesium acrylate monomer solution, after the main material and reducer of the spraying-film waterproof material are mixed and the auxiliary material and oxidizer are mixed, when the main material and auxiliary material are sprayed to a wall surface or any other application substance surface by a two-inlet one-outlet spray gun, the adhesive action of the polyvinyl alcohol is utilized to promote the components A and B of the spraying-film waterproof material to be quickly bound with the coating substance surface, thereby preventing the phenomena of splashing and rebounding, enhancing the use rate of the acrylate material and reducing the material waste. The spraying-film waterproof material is convenient for construction, and better protects good health of the constructors.

Description

technical field [0001] The invention relates to a spray-film waterproof material, in particular to a liquid spray-coat waterproof material, in particular to a spray-film waterproof material capable of preventing splashing and its preparation and use methods, belonging to the technical field of waterproof coatings. Background technique [0002] In tunnels and other underground projects of basic engineering facilities, the requirements for anti-leakage water are very high. The waterproofing measures currently adopted are usually by spraying film construction, that is, spraying the main material of spraying film in liquid state on the surface of the main body of the project or geomembrane that needs to be waterproofed, and the coating will solidify after drying to form a layer. Waterproof membrane to achieve the purpose of waterproofing. In order to speed up the formation time of the waterproof film, the prior art is to divide the waterproof spray film material into two parts,...

AI Technical Summary

Problems solved by technology

However, in the process of spraying the waterproof membrane on the wall or wall on the surface of the main body of the project, it is found that there is a common problem in the above-mentioned prior art, that is, when the waterproof coating is sprayed on the wall or the wall, its contact with the wall or the wall In an instant, under the injection pressure of the spray gun, after the liquid waterproof coating touches the wall, some of the liquid material will collide with the wall or the wall and splash outwards, thus splashing on the builder or splashing on the ground, especially Especially in the construction of waterproof spray film coating in special tunnels with poor working environment, the phenomenon of splash rebound is particularly serious. The splash rebound during the spraying process of this kind of paint not only brings construction difficulty to the staff, but also greatly reduces The utilization rate of acrylate materials has caused a high degree of waste and loss of materials, and the waterproof spray coating that splashes and rebounds is easy to be inhaled by construction operators and damage their health

[0005] In the prior art, in order to alleviate the splash rebound phenomenon in the paint spraying process, it is usually adjusted by adjusting the air pressure of the spray gun, but the effect of this adjustment is not ideal, and when the air pressure is adjusted to be small, the spraying efficiency is greatly improved. reduce, and this method also increases equipment cost and operational difficulty
