Problems solved by technology

In recent years, my country has experienced rapid growth in many fields such as construction, transportation, petrochemicals, hydropower, and marine engineering, which in turn has driven the rapid growth of demand for related supporting products. The anti-corrosion coating market in my country has also shown a gratifying situation. It has already ranked second only to architectural coatings. However, most of the protective coatings currently on the market have problems such as poor adhesion, too thin paint film, no water resistance, high temperature resistance, and easy corrosion.

Abstract

The invention discloses a mirror back protection coating for a solar reflecting mirror. The protection coating comprises the following components in percentage by weight: 40-60% of fluorocarbon resinF-400, 2-10% of pigment of various colors, 5-10% of talc powder, 6-12% of heavy calcium carbonate, 4-8% of zinc phosphate, 5-8% of aluminum tripolyphosphate, 2-8% of organic bentonite, 2-8% of a wetting dispersant, 1-3% of a leveling agent, 1-2% of a defoaming agent, 1-2% of a silane coupling agent Z-6030, 20-30% of a diluent and 10-16% of a curing agent N-75. The mirror back protection coating for the solar reflecting mirror provided by the invention can be used by shower coating, roller coating, brush coating, and spray coating. The product has the characteristics of high drying speed, compact paint film, strong adhesive force, high and low temperature resistance, water resistance, moisture resistance, heat resistance, corrosion resistance, good cutting performance and edge abrasion resistance.

Description

【Technical field】 [0001] The invention relates to a mirror back protective paint for a reflector, in particular to a mirror back protective paint for a solar reflector. 【Background technique】 [0002] Anti-corrosion coatings are widely used in modern industry, transportation, energy, marine engineering and other departments. According to the degree of corrosion resistance of the coating film and the requirements for use, anti-corrosion coatings are usually divided into two types: general-purpose and heavy-duty anti-corrosion. Different types of anti-corrosion coatings are selected according to the use of corrosive media in the environment. Under the corrosive conditions of the general atmospheric environment, such as machine tools, automobiles, railway vehicles, construction machinery and other industries, general-purpose anti-corrosion coatings are often used, and the coating is also required to have a high decorative function; in industrial or marine atmospheric corrosion...
