Thin layer application type water-proof and thermal insulation coating

Abstract

A water-proof and insulating thin-layer paint is proportionally prepared from elastic emulsion of acrylic acid, asbestos wool, talc powder, defoaming agent, anticorrosion agent, thickening agent, water, hollow glass micro-beads, disperser and opaque polymer. Its advantages are high water-proof and insulating effect, and thin coated layer (2mm).

Description

technical field [0001] The invention relates to the field of building materials, in particular to waterproof and thermal insulation coatings. Background technique [0002] With the rapid development of my country's economy, people's requirements for the quality of buildings are getting higher and higher. In the past few years, the country has formulated a series of policies and regulations for building waterproofing projects, which has greatly improved the waterproof quality of buildings in our country. Now from the perspective of energy conservation, my country has put forward the slogan of building energy conservation, especially the insulation and energy conservation of buildings themselves, which is the development direction vigorously advocated by the country. In view of this, in the long-term work experience, the applicant has explored a production method of a thermal insulation coating integrating waterproofing and thermal insulation. [0003] Most of the waterproof a...

Problems solved by technology

The three patents disclosed above all have the effect of waterproofing, heat insulation and heat preservation. Their common disadvantage is that the elongation at break of the coating is small due to the low mechanical strength of the main heat insulating materials added, such as perlite and vermiculite. , the waterproof effect and wear resistance are poor, and it needs thick coating (generally 2-5cm) to play a better thermal insulation effect, which is time-consuming and laborious, the decorative effect is poor, and the material cost is high
