Problems solved by technology

[0003] At present, in the production process of glass fiber reinforced polyurethane profiles, polyurethane resin is coated on the surface of the profiles. This coating not only improves the aesthetic effect of the profiles, but also has various properties, such as acid and alkali resistance, aging resistance, Abrasion resistance, etc., the surface of the profile is sprayed with a coating to ensure the strength and flatness of the profile surface, but the current polyurethane resin is not very good in heat insulation and hardness tests, and the profile is easy to fall off under high temperature conditions

Abstract

The invention discloses a glass fiber reinforced polyurethane profile coating and a coating process. The coating comprises a diphenol propane epoxy resin emulsion, a vinyl modified water-soluble emulsion, a polyester resin emulsion, a coalescing agent, a lubricant, a silane coupling agent, aerogel, a PEG softening agent and deionized water. According to the invention, the aerogel is added into the coating and has relatively high compatibility with the profile, so that the surface thickness of the coating can be reduced and the heat resistance and water resistance of the coating can be improved while the strength of the coating of the profile is ensured, and the profile can not generate the conditions of bubbles and skin shedding under the action of high temperature; in the film covering process, an adhesive material with organic materials and high compatibility is adopted to be connected with the outer covering film, and the hardness and the adhesion strength of the coating are guaranteed.

Description

technical field [0001] The invention relates to the technical field of polyurethane profiles, in particular to a glass fiber reinforced polyurethane profile coating and a coating process. Background technique [0002] Polyurethane coatings (referred to as PU coatings) are coatings formulated with polyurethane resin as the main film-forming substance, together with pigments, solvents, catalysts and other auxiliary materials. In the PU coating system, -NCO / -OH two-component polyurethane coatings are favored by people because of their excellent properties such as water resistance, aging resistance, friction resistance, and bright and plump coating appearance. It is composed of isocyanate and polyester. The prepolymer A component containing -NCO group synthesized by polyol, and the B component containing -OH group active group, crosslinking agent, etc. are composed. [0003] At present, in the production process of glass fiber reinforced polyurethane profiles, polyurethane resi...
