A kind of spray film waterproof material and its preparation and application method

Abstract

The invention discloses a film-spraying waterproof material which is prepared from the following raw materials in parts by weight: 100 parts of magnesium acrylate monomer solution, 0.01-0.1 part of tetrasodium ethylenediamine tetraacetate, 0.01-0.1 part of copper acetate, 2-20 parts of silica white and 2-20 parts of calcium carbonate. The invention also discloses a preparation method of the film-spraying waterproof material, which comprises the following steps: adding the tetrasodium ethylenediamine tetraacetate and copper acetate into the magnesium acrylate monomer solution, uniformly stirring and mixing, adding the silica white and calcium carbonate, and stirring with a high-speed dispersion machine to obtain the film-spraying waterproof material. The invention also discloses an application method of the film-spraying waterproof material. The film-spraying waterproof material disclosed by the invention solves the problem that the original film-spraying waterproof material must be stored and transported in the refrigeratory state under high-temperature conditions, saves the cost, widens the application range, and lays solid foundation for the development of the film-spraying waterproof material.

Description

technical field [0001] The invention relates to the technical field of spray-film waterproof materials, in particular to a spray-film waterproof material and methods for preparing and using the same. 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 adopted are usually through spray film construction. The main material of the spray film is sprayed on the surface of the main body of the project or behind the geomembrane to form a waterproof film to achieve the purpose of waterproofing. In recent years, the application of spray film waterproof materials in tunnels and underground projects has become increasingly widespread, and the consumption has increased year by year. [0003] For example, Chinese Patent Application No. CN201210388153.9 discloses a film-sprayed waterproof material filler resistant to strong alkaline water environme...

Problems solved by technology

Refrigeration is a commonly used method at present. However, this method that not only increases the application cost but also limits the refrigeration requirements of the construction environment has plagued the development of spray film materials.
