Abstract

The invention relates to PU white primer beneficial to low-temperature quick drying and free of prickly heat. The PU white primer is composed of a component A and a component B, wherein the componentA is prepared from the following raw materials in parts by weight: 3-8 parts of coconut oil resin, 17-23 parts of fatty acid alkyd resin, 1-3 parts of butyl acetate, 19-25 parts of titanium dioxide, 30-45 parts of ground calcium carbonate, 0.1-0.3 part of an antifoaming agent, 0.8-2.5 parts of an anti-settling agent, 0.05-0.15 part of leveling agent and 1.5-2.5 parts of propylene glycol methyl ether acetate, and the component B is prepared from the following raw materials in parts by weight: 25 to 50 parts of a mixed solvent, 0.3 to 0.7 part of a dehydrating agent, 5 to 9 parts of Demoder L75(C), 20 to 25 parts of BG-450 TB, 25 to 35 parts of DESMODUR IL 1451 and 2 to 4 parts of HT-100 HDI. According to the PU white primer, a mixture of coconut oil resin, fatty acid alkyd resin and castoroil resin is selected as a main film-forming material, so that the polishing property is improved, the drying speed is increased, the flexibility is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a PU white primer which is good for low-temperature rapid drying and does not suffer from heat rash. Background technique [0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous solid film firmly attached to the object to be coated, also known as paint film or coating, usually based on resin, or oil, or emulsion, adding Or do not add pigments, fillers, add corresponding additives, and use organic solvents or water to prepare viscous liquids. There are many classifications of coatings, which are divided according to the form of the product, mainly including solvent-based coatings, water-based coatings, powder-based coatings, high-solid coatings, metallic coatings, pearlescent coatings and solvent-free coatings. According to the brightness of the appearance of the coating film, it can be divided into matt, flat, matte and high...
