Abstract

The invention provides a waterproof thermal-insulation coating with organosilicon-modified styrene-acrylic emulsion. The waterproof thermal-insulation coating is prepared from the following componentsin parts by weight: 80-100 parts of organosilicon-modified styrene-acrylic emulsion, 20-25 parts of hollow glass bead, 8-15 parts of diatomite, 5-10 parts of nano titanium dioxide, 30-40 parts of cement, 20-30 parts of talcum powder, 20-30 parts of quartz powder, 0.2-0.5 part of silane coupling agent, 3-6 parts of dispersing agent, 2-4 parts of plasticizer, 0.2-0.5 part of defoaming agent, 1.0-2.5 parts of film-forming additive, 0.1-0.3 part of lubricant, 0.2-0.5 part of preservative and 20-30 parts of deionized water.

Description

technical field [0001] The invention relates to a waterproof and heat-insulating paint, in particular to a silicone-modified styrene-acrylic emulsion waterproof and heat-insulating paint. Background technique [0002] "Heat insulation coating": refers to a functional water-based coating developed in recent years that blocks, reflects, and radiates near-infrared heat from sunlight, which can insulate and cool roofs, save energy and reduce consumption. It has the characteristics of heat insulation, waterproof, anti-rust, anti-corrosion, short construction period, and quick results. It completely replaces the water spray system, thermal insulation cotton, foam sponge, interlayer iron sheet, etc. There are three main classifications of thermal insulation coatings in terms of characteristics and principles, insulating conductive thermal insulation coatings, reflective thermal insulation coatings and radiation thermal insulation coatings. In addition to the above three types of t...
