Coating material for modified bitumen waterproof roll material surface and preparation method

Abstract

The invention discloses a coating material for a modified bitumen waterproof roll material surface. The coating material is prepared by three sections of raw material proportions of a film-forming agent, synthesis of the film-forming agent and preparation of the coating material. The raw material proportions of the film-forming agent are as follows: 30.0-50.0 parts by weight of deionized water, 0.2-0.5 part by weight of an initiator, 0.8-1.5 parts by weight of an emulsifier, 1.0-5.0 parts by weight of a stabilizer, 25.0-40.0 parts by weight of acrylate, 0.8-1.2 parts by weight of an organic acid, 10.0-15.0 parts by weight of phenylethylene and 3.0-5.0 parts by weight of organosilicone. The raw material proportions of the coating material are as follows: 45.0-55.0 parts by weight of the film-forming agent, 0.1-0.3 part by weight of a dispersing agent, 0.3-1.0 part by weight of a defoaming agent, 40.0-65.0 parts by weight of a filling material and 0.2-0.5 part by weight of a thickening agent. The coating material is prepared after synthesizing the film-forming agent according to the above raw material proportions. The coating material has the functions of heat preservation and heat insulation, and can resist solar irradiation of solar ultraviolet improve the service life of the modified bitumen waterproof roll material.

Description

technical field [0001] The invention relates to a building waterproof material, in particular to a composition and a preparation method of a cover layer material used for modifying the surface of an asphalt waterproof coiled material. The covering layer material has the functions of heat preservation, heat insulation and ultraviolet radiation resistance, and improves the service life of the modified asphalt waterproof coiled material. Background technique [0002] At present, manufacturers of modified asphalt waterproofing membrane products in my country hope to take various measures to improve the service life of the product and expand the application range in order to avoid direct erosion of the sun rays and other harmful gases on the modified asphalt layer of the membrane. Its surface is compounded with a layer of aluminum-plated silver polyester film, or a layer of colored sand, mica rock flakes and other materials are sprayed on the production line, or the surface of the...

AI Technical Summary

Problems solved by technology

a. Granular colored sand, mica flakes and other materials cannot completely cover the modified asphalt layer, and the gaps between many particles can still irradiate sunlight and accumulate heat; b. Covered colored sand, mica flakes and other materials have improved the volume The overall weight of the material increases the labor intensity and overall cost of the production, transportation and construction process;

[0005] 3. It is not appropriate to make a protective layer of cement mortar on the surface of the rolled material. The problem is: a. Increase the construction process, labor intensity of workers, load of the building and material cost; b. Cement mortar When cracked, it still cannot block the erosion of sunlight and other harmful gases
