The first type of solvent-based coatings: there are many types of such coatings and the quality is good, but the cost is high, the safety is poor, and the use is not very common
The second type is water-emulsion type and reactive polymer coatings: it is difficult to uniformly disperse various reinforcing agents, fillers, and polymer elastomers in the colloid for this type of coating, and can only be added by grinding. A small amount of compounding agent, reactive polyurethane is two-component, easy to deteriorate, high cost

Abstract
The invention discloses a metal roof waterproof coating. The metal roof waterproof coating comprises 1 to 2 parts by weight of ammoniumhydroxide, 1 to 3 parts by weight of a surfactant, 5 to 15 partsby weight of an acrylic emulsion, 10 to 25 parts by weight of a polyurethane modified acrylate waterproof emulsion, 1 to 5 parts by weight of a siliconewaterproofing agent, 0.5 to 3 parts by weightof silica, 20 to 40 parts by weight of a pigment filler, 0 to 0.5 parts by weight of a bactericidal preservative, 0 to 1 part by weight of an anti-aging agent, 0.2 to 0.8 parts by weight of a dispersing agent, 0.4 to 1 part by weight of a defoaming agent, 0.5 to 2 parts by weight of a film-forming aid, 0.6 to 3 parts by weight of hydroxyethyl cellulose, 0.3 to 1 part by weight of ammonium metavanadate and 10 to 30 parts by weight of water. The metal roof waterproof coating has high elasticity and excellent waterproof performances and is non-toxic, tasteless, safe and environmentally friendly.The coating film has high water resistance, alkali resistance, UV resistance, high elongation at break, tensile strength and an automatic repair function.
Description
technical field [0001] The invention belongs to the field of building materials, and more specifically relates to a metal roof waterproof coating. Background technique [0002] There are two types of waterproof materials on the market: one is polyurethane waterproof coatings. Such materials are generally made of polyurethane and coaltar as raw materials. The tar gas it volatilizes is highly toxic and not easy to remove, so it was banned in China in 2000. The polyurethane waterproof coating that is still on sale uses asphalt instead of coaltar as a raw material. However, when using this kind of coating, it is generally diluted with organic solvents such as toluene and xylene, so it also contains toxicity; the other type is polymercement-based waterproof coating. It is composed of a variety of water-based polymer emulsions and high-quality cement mixed with various additives. The flexibility of the polymer (resin) and the rigidity of the cement are integrated, making it ...
