preparation example Construction

[0018] The invention provides a black paint for automobiles and a preparation method thereof, which is characterized in that the preparation method comprises: 2-3% by weight of carbon black, 30-40% by weight of 1387 resin, 2-4% by weight After mixing butyl acetate cellulose, 2-4% weight ratio of dispersant, 1-2% weight ratio of white water, 0.1-0.5% weight ratio of leveling agent and the rest as solvents, the black color for automobiles is obtained. coating.

[0019] Carbon black is well known to those skilled in the art, and the grinding fineness of said carbon black is ≤20 μm.

[0020] The original function of the diluent is to reduce the concentration of the effective components in the paint and increase the spraying performance. The diluent can be a mixture of butyl acetate and propylene alcohol methyl ether acetate.

[0021] The dispersant is a high-molecular-weight block copolymer solvent containing pigment affinity groups; the bleaching water is ethylene glycol monobut...

Abstract

The invention relates to the technical field of automobile coatings, in particular to a black coating for automobiles and a preparation method thereof. The black coating for automobiles is prepared bymixing the following components in percentage by weight: 2-3% of carbon black, 30-40% of 1387 resin, 2-4% of butyl acetate cellulose, 2-4% of dispersing agent, 1-2% of white water, 0.1-0.5% of leveling agent and the balance of solvent.

Description

technical field [0001] The invention relates to the technical field of automobile coatings, in particular to a black coating for automobiles and a preparation method thereof. Background technique [0002] Automobile coatings refer to the coatings applied on the body and parts of various vehicles such as cars, and generally refer to coatings and auxiliary materials for new cars and coatings for vehicle repairs. Automotive coatings include automotive body OEM paints, automotive refinish paints, auto parts paints, and PVC anti-stone chip coatings. [0003] Chinese patent CN104164105A discloses a coating for automobiles, which is made of the following raw materials in parts by weight: 10-15 parts of nitrocellulose, 13-18 parts of nitrocellulose, 11-20 parts of epoxy resin, 3 parts of linseed oil -9 parts, itaconic acid 5-9 parts, ethylene glycol ether 3-9 parts, diene epoxy resin 2-8 parts, zinc oxide 3-7 parts, talcum powder 1-3 parts. The beneficial effect of this patent is ...
