Problems solved by technology

[0003] However, in underground projects in high-latitude cold regions, since the construction area and climate are generally below 5°C, crystals will appear in the main material of the spray film. Due to the appearance of crystal particles, the spray gun will be blocked, which seriously affects the progress of spray film construction.

Embodiment 1

[0027] In 100 parts of magnesium acrylate monomer aqueous solution, add 1 part of 60% (wt) or more glycerin, after mixing evenly, carry out high-speed stirring of more than 1500 revolutions per minute until there is no visible agglomerated particles in the solution, that is, obtain the present example Waterproof spray film material. Placed at an altitude of 3800m, at a temperature of -5°C, no crystals precipitated.

Embodiment 2

[0029] The composition and preparation method of this example and Example 1 are basically the same, except that 20 parts of 60% (wt) glycerol is added. Replace high-speed stirring with a ball mill until no agglomerated particles are visible in the solution. Placed at an altitude of 3800m, at a temperature of -5°C, no crystals precipitated.

Embodiment 3

[0031] The present embodiment is basically the same as the first embodiment, except that 10 parts of 70% (wt) glycerin and 10 parts of magnesium chloride hexahydrate are added. Replace high-speed stirring with a colloid mill until no agglomerated particles are visible in the solution. Placed at an altitude of 3800m, at a temperature of -5°C, no crystals precipitated.

Abstract

The invention provides a waterproof film spraying material, and a preparation method and application thereof. The preparation method comprises the following steps: adding 1-20 parts of 60 wt% above glycerol into 100 parts of magnesium acrylate monomer water solution, uniformly mixing, adding 0-30 parts of magnesium chloride hexahydrate, and evenly mixing until no visible agglomerated particles exist in the solution, thereby obtaining the waterproof film spraying material. The waterproof film spraying material, which is used as a main material, can be sprayed and mixed with an oxidizer and a reducer to instantaneously form a gel, and the gel is bonded to the treated base surface to form a film layer. The waterproof film spraying material can not crystallize in a high-altitude low-temperature envelopment, thereby ensuring the continuity of the main material and effectively ensuring the smoothness of the waterproof film spraying construction in the region.

Description

technical field [0001] The invention belongs to the field of waterproof materials, in particular to a waterproof spray film material and its preparation method and application. 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 to form a waterproof film to achieve the purpose of waterproofing. [0003] However, in underground projects in high-latitude cold regions, since the construction area and climate are generally below 5°C, crystals will appear in the main material of the sprayed film. Due to the appearance of crystal particles, the spray gun will be blocked, which seriously affects the progress of the sprayed film construction. Contents of the invention [0004] The purpose of the ...
