Foamed polyurethane intramode paint color modifier and preparation method thereof

Abstract

The invention discloses a foamed polyurethane intramode paint color modifier and a preparation method of the foamed polyurethane intramode paint color modifier. The foamed polyurethane intramode paint color modifier comprises the following ingredients in parts by mass: 10 to 20 parts of acrylic resin, 20 to 30 parts of solvents, 1 to 2 parts of anti-settling agents, 50 to 60 parts of fillings and 1 to 8 parts of pigments, wherein the acrylic resin is thermoplastic weatherability type acrylic resin of 50 percent dimethylbenzene solution, the solvents are arene S-100 solvents with the boiling point being 157 to 174 DEG C, the anti-settling agents are bentonite or gas-phase silicon dioxide, the fillings are quartz sand, calcium carbonate or barium sulfate, and the pigments are iron oxide red, iron oxide yellow or carbon black. The color modifier disclosed by the invention is suitable for color modification on the foamed polyurethane intramode paint surface, the material impurity effect of a stone plate after the color modifying is extremely similar to that of a natural stone plate, and the color and the luster are very distinct, natural and attractive. In addition, the color modifier disclosed by the invention has good performance of adhesive force, weather resistance, water resistance, durability and the like.

Description

technical field [0001] The invention relates to a color-correcting agent and a preparation method thereof, in particular to a color-correcting agent which can be used for color-correcting the surface of foamed polyurethane in-mold coatings and a preparation method thereof. Background technique [0002] The imitation natural stone plate material is a new type of decorative material, which can be produced by spraying special in-mold paint on the inner surface of the foamed polyurethane mold, and then foaming polyurethane. The shape and color of imitation natural stone board materials are similar to those of natural stone boards, and it has a series of advantages such as good decorative effect, fire prevention, waterproof, and light weight. Therefore, this kind of decorative material has been more and more used in high-end outdoor decoration Many, especially in high-end low-rise buildings in South America and other places. However, compared with natural stone slabs, this imita...
