Abstract

The invention relates to the field of coating, in particular to coil coating and a production method thereof. The coil coating comprises the following raw materials in parts by weight: 80-120 parts ofepoxy resin, 50-70 parts of acrylic resin, 15-20 parts of polyvinylidene fluoride, 3-5 parts of garnet, 10-15 parts of glass fiber, 5-10 parts of titanium dioxide, 5-10 parts of zinc oxide, and 0.5-2parts of auxiliary agent. The prepared coil coating has a reflection effect on ultraviolet light, prevents the aging, powdering, cracking and other damage of a formed film caused by the photochemicalreaction of the ultraviolet light on a coating, and enhances the weather resistance of the coating; and the coil coating has excellent comprehensive mechanical properties, high storage stability, good decorativeness, protectiveness, durability, stamping resistance, abrasion resistance, light resistance, weather resistance, scratch resistance, physical hardness and the like, fine texture, smooth appearance, no dust accumulation, gloss and color retention and excellent adhesiveness, and is not easy to yellow.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a coil coating and a production method thereof. Background technique [0002] With the continuous maturity of technology, the development of coil coatings is very fast. Coil materials were first put into the market in the United States in the 1930s, while the development history of coil coatings in my country began in the 1980s. Coil coatings are not as familiar and well-known as architectural coatings and furniture coatings in the coatings industry, but they are also an indispensable industrial coating for social development. [0003] Coil coating is a special coating mainly used to coat the surface of steel plate and aluminum plate to make pre-coated coil. At present, coil coating technology is mainly developed in the direction of ultra-long life, product functionality and environmental friendliness, and is constantly exploring new application fields. Coiled materials are widely used ...
