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 polymer compound obtained by reacting only with carbon-carbon unsaturated bonds, in particular to a transparent and colored thermosetting acrylic resin and its preparation method and application. Background technique: [0002] Thermosetting acrylic resin means that there are certain functional groups in the resin, which form a network structure by reacting with functional groups in melamine resin, epoxy resin, polyurethane, etc. added during paint making. It has excellent fullness, luster, hardness, solvent resistance, and weather resistance. When baked at high temperature, it does not change color or yellow. An important application of thermosetting acrylic resin is to combine with melamine resin to form acrylic-amino baking varnish, which is widely used in products such as automobiles, motorcycles, bicycles, coiled steel, and gold and silver wires. In the prior art, to obtain a transparent and colorful acrylic baking varn...
