Spraying film waterproof material, two-component spraying film waterproof material and using method thereof

Abstract

The invention relates to a spray film waterproof material, a two-component spray film waterproof material and a use method thereof, the spray film waterproof material can form a component A and a component B, the component A comprises the following raw materials by weight: 100-130 parts of an acrylate monomer solution; the component B is prepared from the following raw materials in parts by weight: 100 parts of acrylate monomer solution, 0.5 to 5 parts of modified silicone, 0.01 to 0.1 part of humectant and 5 to 20 parts of filler; the use method comprises the following steps: (1) adding an initiator A into the component A to form a mixed solution A, and adding an initiator B into the component B to form a mixed solution B; (2) simultaneously spraying a mixed solution A and a mixed solution B through double-cylinder spraying equipment; and (3) mixing the two mixed solutions at the intersection point with the spraying distance of 40-50cm, initiating polymerization reaction to form gel, and adhering the gel to a basal plane to form a film layer. The cohesiveness of the silicone and the cohesiveness of the polyacrylate are superposed, so that the cohesiveness of the waterproof film layer is improved.

Description

technical field [0001] The invention relates to a waterproof material, in particular to a spray-film waterproof material, a two-component spray-film waterproof material and a use method thereof. Background technique [0002] Acrylate spray film waterproof technology is a system technology composed of film-forming materials, spray film equipment, construction technology, and detection methods. It mainly includes three aspects: the formulation of film-forming materials, spraying equipment and spraying process. The film-forming material is a two-component main liquid (A and B components) prepared from an acrylate solution, which is transported to the spray gun through special equipment. The two liquids undergo instant polymerization in the air, and quickly form a certain strength and toughness. Elastic waterproof membrane layer. [0003] In the prior art, many patents about acrylate sprayed film waterproofing materials have been disclosed, such as a silane-modified sprayed fi...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned spray film waterproof materials can usually meet the general waterproof requirements, but under the conditions of rainy season construction or water immersion after spray film, due to the insufficient adhesion of the waterproof film layer in a short period of time, it is easy to bulge and fall off when immersed in water. Reduce the waterproof performance and anti-water channeling ability of the waterproof membrane layer; after spraying the membrane, the drying speed is too fast to cause dry cracks and other problems. The requirements for the front and rear processes are strict and water conservation and maintenance are required, which increases the difficulty of construction.
