Abstract

The invention relates to a flatting agent for aluminum paint and a preparation method thereof. The flatting agent comprises the following components by weight percent: 5%-19.5% of dimethylbenzene, 15.5%-45% of butyl acetate, 1%-9% of butyl acetate cellulose and 42%-72% of polyether modified polysiloxane. The preparation method of the flatting agent for aluminum paint comprises the following steps of: 1) fully stirring 10%-30% of dimethylbenzene and butyl acetate and the butyl acetate cellulose, thereby obtaining an A group raw material; 2) fully stirring the polyether modified polysiloxane and 70%-90% of the butyl acetate, thereby obtaining a B group raw material; and 3) fully mixing and stirring the A group raw material and the B group raw material, thereby obtaining an end product. The flatting agent for aluminum paint has the function of boosting the array of aluminum powder (silver powder), and can accelerate and balance the volatilization of a solvent, and the recoatability of a painting layer is difficult to cause.

Description

technical field [0001] The invention relates to the use of a compound used as a leveling agent, in particular to a leveling agent for aluminum powder coatings and a preparation method thereof. Background technique [0002] Generally, when the leveling agent is added to the coating with aluminum powder (silver powder), it only forms leveling on the surface of the coating. [0003] It cannot promote the arrangement of aluminum powder (silver powder), cannot accelerate and balance the volatilization of solvents, and, [0004] It is easy to cause recoatability of the coating, which is its disadvantage. Contents of the invention [0005] The object of the present invention is to provide a method that can promote the arrangement of aluminum powder (silver powder), and can accelerate [0006] And balance the volatilization of solvents, and it is not easy to cause the leveling agent of aluminum powder coating and its preparation [0007] method. [0008] The technical solution...
