Solar light reflection paint for metal and preparation method of solar light reflection paint

Abstract

The invention provides solar light reflection paint for metal and a preparation method of the solar light reflection paint. The paint comprises the following raw materials in parts by mass: 4-12 parts of water, 1-2 parts of attapulgite, 0.3-0.7 part of sodium bicarbonate, 2-4 parts of wollastonite in powder, 0.3-0.7 part of zinc stearate, 0.1-0.3 part of alkylphenol polyoxyethylene ether, 0.1-0.3 part of sodium dodecyl benzene sulfonate, 10-20 parts of diatomite, 30-45 parts of silicone acrylic emulsion, 8-18 parts of acrylic emulsion, 1-3 parts of propanediol butyl ether, 10-22 parts of ceramic particles, 1-4 parts of sodium tripolyphosphate, 0.5-2 parts of magnesium sulfate, 6-12 parts of electric-precipitation coal ashes, 3-9 parts of lead oxide and 0.1-0.5 part of sodium silicate. The paint provided by the invention has good performances such as reflection, elasticity and wear resistance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a solar light reflecting coating for metals and a preparation method thereof. Background technique [0002] Metal is a shiny, malleable, easily conductive, thermally conductive substance. The above properties of metals are all related to the free electrons contained in the metal crystals. In nature, most metals exist in a compound state, and a few metals such as gold, platinum, silver, and bismuth exist in a free state. Metals are used in a very wide range of applications. Many outdoor fixtures are made of metal. People protect metals by applying paints to their surfaces. However, due to being placed outdoors for a long time, the paint is easy to age and fade, and is easy to be worn. [0003] Existing coatings for metals currently on the market have poor sunlight reflection properties, low elasticity, poor impact resistance, and poor thermal insulation and wear resistance properties....

AI Technical Summary

Problems solved by technology

However, due to the long-term outdoor, the paint is easy to age and fade, and it is easy to be worn

[0003] Existing metal coatings currently on the market have poor solar reflection properties, low elasticity, poor impact resistance, and do not have good thermal insulation and wear resistance

For example, the Chinese invention patent (patent number 201310734028.3, application date 2013-12-26) discloses a water-based environmentally friendly reflective thermal insulation coating for metal surfaces. The coating can effectively reflect thermal insulation, has good thermal insulation effect, and has stable thermal insulation performance and corrosion resistance , long service life, environmental protection and no pollution, but its wear resistance and impact resistance are poor, and it is easy to peel off when it is impacted; Chinese invention patent (patent number 201110195842.3, application date 2011-07-13) discloses an ultra-thin metal plate A heat-insulating reflective coating and a preparation method thereof, the coating has the advantages of thin coating thickness, wide application range, and convenient construction, but has poor anti-reflection performance, low elasticity, and poor impact resistance
