Abstract

The invention relates to relates to a flame retardation type exterior coating capable of automatically cleaning, the coating takes epoxy resin slurry and methacrylate as monomer. The exterior coating comprises the following raw materials by weight: 20-40 parts of vinyl epoxy resin slurry, 5-30 parts of n-butyl methacrylate, 0.5-2.5 parts of phosphate tri(2-chloropropyl)ester, 1-10 parts of hydrophobic silica, 0.1-5 parts of titanium dioxide, 0.1-2 parts of levelling agent, 0.1-2 parts of antifoaming agent, 0.5-5 parts of silicon auxiliary agent and 1-5 parts of initiator. When the coating is used, the monomer initiates a polymerization through a radical initiator to form a thermosetting polymer, a contact angle with water is greater than 110 DEG, and a roll angle is less than 65 DEG. The water-repellency grade is grade 4, and the oil-repellency grade is grade 2. The hydrophobicity can reach 96%, the heat conduction coefficient is 0.032W / mK, the combustion grading accords with a grade C, and all the indexes can reach an international relative standard.

Description

technical field

[0001] The invention belongs to the field of architectural coatings, in particular to a self-cleaning flame-retardant exterior wall coating. Background technique

[0002] Flame-retardant coatings are coated on the surface of non-refractory substrates during construction, which can reduce the surface combustion ability or reduce the degree of damage when subjected to flames, thereby weakening the spread of flames, providing valuable time for firefighters and reducing losses. drop to lowest.

[0003] Although the existing flame-retardant coatings have their own unique advantages, they still show some shortcomings when used as exterior wall coatings. In particular, the lack of antifouling ability will make the coating Discoloration or even falling off will occur, which will affect the appearance and even cause safety hazards, which has also become a factor limiting the development of this type of product.

[0004] my country is currently in the peak period of ...
