Abstract

The invention belongs to the technical field of waterproof coatings, and particularly relates to a quick-drying waterproof exposure type waterproof coating, which is prepared from the following raw materials in parts by weight: 1 to 5 parts of polyether polyol, 3 to 18 parts of polyethylene glycol, 3 to 8 parts of fluorine-containing monomer, 1 to 10 parts of polyether-ether-ketone oligomer, 10 to 30 parts of polyisocyanate, 0.01 to 0.1 part of catalyst, 0.01 to 0.05 part of acetone and 0.5 to 3 parts of an amine chain extender. According to the waterproof coating provided by the invention, through modification treatment of the polyisocyanate curing agent, a large number of rigid structures are introduced to a PUD molecular chain, and the benzene ring structure of polyether-ether-ketone can significantly accelerate the drying speed of a coating film of the finally prepared waterproof coating, and shorten the surface drying time and the hard drying time of a waterproof coating, the hardness increasing speed of a coating film is increased, and finally the strength of the coating film is improved; and besides, through modification treatment on a polyisocyanate curing agent, various branched structures are introduced into a molecular chain, and the heat resistance of the polyether-ether-ketone is fully exerted, so that the prepared waterproof coating has relatively high thermal stability.

Description

technical field [0001] The invention belongs to the technical field of waterproof coatings, in particular to a quick-drying, water-resistant and exposed waterproof coating. Background technique [0002] Polyurethane waterproof coating is a polymeric elastic waterproof coating. After curing, it can form a dense, strong and flexible waterproof coating on the surface of the base. Because of its excellent performance, easy construction, remarkable waterproof effect and long service life, it has been widely used in various waterproof and anti-seepage projects. The current polyurethane waterproof coatings are mainly based on aromatic products. In order to meet the weather resistance requirements of waterproof coatings, it is necessary to apply a layer of aliphatic anti-aging topcoat on the surface of aromatic coatings. The polyurethane waterproof coating prepared by using aliphatic isocyanate can significantly improve its weather resistance, and can be directly used as an exposed...
