Abstract

The invention discloses a special high-wettability resin for colour mixing. The special high-wettability resin is prepared from coconut oil fatty acid and castor oil. The colour paint / colour paste for wood lacquer, which is prepared from the resin, is good in appearance and free from layering, flooding and pig shin during a storage process. After lacquer spraying, the coating is high in adhesion force, pigments in a coating film are uniformly in arrangement and free from flooding and floating phenomena; meanwhile, the lacquer film is good in weather resistance and not liable to yellow. The high-wettability special resin is high in light-protection and colour-protection performances, and especially suitable for producing white paint, and the colour pastes of the various pigments.

Description

technical field [0001] The invention belongs to the technical field of coating resins, and is a short-oil hydroxyl-modified acid-acid resin produced by joint modification of fatty acids and drying oils, and has strong oiliness and wetting compatibility. Background technique [0002] At present, resin occupies the main component of paint, which is directly related to the quality of paint performance. Conventional acid-acid resins are difficult to meet the production of wood paint paint / color paste. Each pigment has strong oil absorption, and the particle size and specific gravity are inconsistent. Disadvantages such as uneven color, floating powder, etc. Contents of the invention [0003] The purpose of the present invention is: to provide a special resin with high wettability for toning, which has very complete esterification, uniform molecular structure, good weather resistance, good oiliness, good wetting compatibility, and solves the problem of pigments and pigments. ...
