Abstract

The invention discloses an aqueous mirror back aluminum plated protective coating which comprises the following raw materials in percentage by weight: 19-25% of a 65% solid content aqueous pure acrylic resin, 10-16% of a 65% solid content aqueous epoxy modified acrylic resin, 4-6% of a 100% solid content complete methoxylation amino resin, 33-50 parts of inorganic pigment packing slurry, 4-6 partsof a cosolvent, 4-6 parts of a composite colloid aid and 8-12 parts of distilled water. By using main body resin, a technical measure of aqueous preparation, and water as a construction medium, the prepared coating has property effects equivalent to those of an oily product on the premise that environment pollution problems caused by excessive VOC (Volatile Organic Compound) emission are solved.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a water-based aluminum-plated protective coating on the back of a mirror. Background technique [0002] At present, the oil-based coating products used for the protection of mirror back aluminized film at home and abroad are relatively mature and the technology is stable, especially in the field of epoxy modification of acrylic, alkyd and other resins, and the homogenization competition in the field of mirror back glass processing is serious. The common denominator is that there are serious environmental problems. In Xingtai and Qinhuangdao in Hebei, Tengzhou in Shandong, Jiaxing in Zhejiang and Dongguan in Guangdong, etc., there are huge market potentials that urgently need to solve environmental protection problems. [0003] As far as the current development trend is concerned, in recent years, the country has stepped up environmental protection efforts, and VOC emissions h...
