Environmental-friendly composite water-proof paint

Abstract

The invention provides an environmental-friendly composite water-proof paint which is characterized by comprising a bottom paint and a surface paint, wherein the bottom paint is prepared by uniformly mixing the following components of 15-60 percent of sodium metasilicate with modulus of 3-4, 0.05-18 percent of triethanolamine, 0.1-15 percent of sodium hexafluorosilicate, 0.2-8 percent of staple glass fibre, 0.2-30 percent of kaolin powder, 0.1-20 percent of quartz powder, 1-40 percent of barium sulfate, 0.2-10 percent of mica powder, 0.1-10 percent of sodium polycarboxylic acid and 0.2-15 percent of 1,2-dibutyl-naphthalene-6-sodium sulfonate; the surface paint is prepared by uniformly mixing the following components of 0.5-10 percent of mica powder, 0.1-60 percent of quartz powder, 2-50 percent of white cement powder, 0.1-10 percent of ethylene glycol, 0.2-20 percent of propylene glycol, 1-30 percent of barium sulfate, 2-40 percent of talcum powder, 0.1-10 percent of hydroxyethylcellulose, 0.2-20 percent of HX-5440, 2-50 percent of 8128 type styrene-acrylate emulsion and 0.05-20 percent of modified polydimethylsiloxane, wherein the content is accounted in the percent by weight. The invention has scientific and reasonable material selection, low price, no pollution, convenient construction, strong adhering force, no combustion, large hardness, high strength, good fire resistance, weather fastness, good durability and water, acid or alkali resistance.

Description

technical field [0001] The invention provides an environment-friendly composite waterproof coating, which belongs to the technical field of coatings. Background technique [0002] Traditional waterproof materials mainly include flexible waterproof materials such as waterproof membranes, waterproof coatings, and sealing ointments, as well as rigid waterproof materials that are based on cement substrates and added waterproofing agents and other additives. [0003] Most waterproof projects in my country use traditional waterproof materials, which have disadvantages such as poor aging resistance, low tensile strength, and sensitivity to temperature. At the same time, there are still the following problems: (1) Traditional waterproof coatings are not environmentally friendly, corrosive, have large shrinkage of their own materials, and poor puncture resistance; (2) Traditional waterproof coatings are less brushed, and it is difficult to detect missing brushes; (3) Traditional wate...

Problems solved by technology

[0003] Most waterproof projects in my country use traditional waterproof materials, which have disadvantages such as poor aging resistance, low tensile strength, and sensitivity to temperature.

At the same time, there are still the following problems: (1) Traditional waterproof coatings are not environmentally friendly, corrosive, have large shrinkage of their own materials, and poor puncture resistance; (2) Traditional waterproof coatings are less brushed, and it is difficult to detect missing brushes; (3) Traditional waterproof coatings The construction base surface has strict requirements and must meet the requirements of solidity, smoothness and drying, otherwise the quality of the project is difficult to guarantee; (4) The traditional waterproof coating process is simple, low in technical content, and easy to fake; (5) If the wall is painted with a large area of ​​waterproof coating, It is difficult to guarantee the requirements for pasting large-size decorative bricks on the facade.

[0004] Traditional waterproof coatings are used for roof waterproofing, which is easy to cause aging, cracking, deformation, breaking, and delamination; for indoor waterproofing, it is difficult to construct for places with complex shapes, and it is even more difficult to guarantee the quality of leakage. It takes a lot of money and labor to repair every few years, which not only disrupts people's normal life, work and production order, but also affects the service life of the entire building.
