Abstract

A colorful and transparent hot-setting acrylic resin possesses the general formula A(M)n, in which A is hot-setting acrylic resin, M is premetallized dye and n is integer between. The steps as the following: first, premetallized dye reacting with acrylic ester to form premetallized olefin integral compound; second, preparing colorful and transparent hot-setting acrylic resin. The invention can be used in preparation of acrylic lacquer to ensure stable and homogeneous color.

Description

Technical field: [0001] The invention relates to a high molecular compound obtained only by the reaction of carbon-carbon unsaturated bonds, in particular to a transparent and colored thermosetting acrylic resin, a preparation method and its application. Background technique: [0002] Thermosetting acrylic resin refers to a certain functional group in the resin, which forms a network structure by reacting with the functional groups in the added melamine resin, epoxy resin, polyurethane, etc. during the paint making process. It has excellent fullness, gloss, hardness, solvent resistance, weather resistance, and does not change color or yellow when baked at high temperature. An important application of thermosetting acrylic resin is to combine with melamine resin to form acrylic-amino baking paint, which is widely used in automobiles, motorcycles, bicycles, coiled steel, gold and silver wires and other products. In the prior art, in order to obtain transparent colored acrylic...
