Problems solved by technology

Although the coating can be applied to outdoor steel structures, due to the addition of a large amount of deionized water and nano-titanium dioxide (titanium dioxide) in the coating, the coating has low glue content, poor crack resistance and toughness, generally only 2- The service life of 3 years is difficult to meet the needs of many occasions
In addition, the addition of nano-titanium dioxide (titanium dioxide) will cover the reflection and refraction of the hollow microspheres, and the heat insulation performance is not very ideal.

Abstract

The invention discloses a semitransparent multifunctional water-based paint which is characterized by mainly comprising the following components in parts by mass: 60-100 parts of water-based acrylic acid or water-based polyurethane emulsion, 0.1-0.5 part of pH value multifunctional assistant, 1-5 parts of a water-based antifreezing agent, 0.1-0.5 part of a wetting agent, 1-5 parts of a coalescingagent, 0.5-1 part of defoaming agent, 0.5-2 part of a mildew-proofing agent, 0.1-0.5 part of a preservative, 0.5-2 part of a flash-rust inhibitor, 0.5-2 part of a water-based coupling agent, 0.5-1 part of fumed silica and 10-20 parts of light heat-insulating microspheres. The product is semitransparent; when light-transmitting materials such as glass and color light tiles are coated with the coating, the light is not shielded and a matte surface is formed, and light pollution is avoided. Meanwhile, the heat insulation performance is more excellent. Tests show that the heat-insulating waterproof paint provided by the invention has the heat-insulating property of more than 15 DEG C, and the coating film has strong adhesion on the base material, and excellent water permeation resistance and cracking resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a translucent multifunctional water-based coating. Background technique [0002] At present, the common emulsion-type waterproof coatings on the market are generally one-component water-emulsion type waterproof coatings prepared by adding a large amount of water and other additives to the acrylic emulsion of the styrene-acrylic system as the colloid. After the coating is cured, it forms a thin waterproof coating, which has poor extensibility, elasticity, crack resistance, impermeability and weather resistance. It is mainly used for waterproofing of balconies, toilets, bathrooms, kitchens, etc., mainly for indoor applications. . [0003] Heat-insulating coating is a functional water-based coating developed in recent years that blocks, reflects, and radiates infrared heat from sunlight to insulate and cool roofs, saving energy and reducing consumption. It has the characteristics...
