Problems solved by technology

[0002] Traditional acid-cured furniture paint, because it contains volatile organic solvents, such as benzene, affects human health and pollutes the environment. Therefore, most companies no longer use such products
However, other types of furniture paints have poor heat resistance and stability, which affects the service life of furniture. In addition, they often have shortcomings such as insufficient filling and weak hardness.

Embodiment

[0010] Embodiment: a kind of preparation technology of topcoat comprises the following steps,

[0011] a. Add 40-80 parts of water, 85-130 parts of polyethylene oxide, 140-170 parts of glycidyl methacrylate and 90-140 parts of toner into the mixer in order, mix and stir, and keep the mixer at 650-750 rpm minutes, stirring for 5 minutes;

[0012] b. Adjustment Adjust the speed of the mixer to 1800-1900 rpm, and then add 75-85 parts of polyethylene terephthalate, 20-40 parts of polyphenylene sulfide, and 25-50 parts of acrylamide in sequence, Disperse at high speed for 30 minutes;

[0013] c. After dispersion, the paint is obtained, and its fineness is less than 60 microns;

[0014] d. Put the paint in cans, seal and pack.

[0015] As preferably, when stirring, the stirrer is reversed once every 5 minutes.

[0016] The invention has excellent heat resistance, comprehensive chemical stability and heat resistance, can still work normally below 200 DEG C, and has good stability...

Abstract

The invention discloses a process for preparing finish paint. The process for preparing the finish paint comprises the following steps of: a, adding 40-80 parts of water, 85-130 parts of polyethyleneoxide, 140-170 parts of glycidyl methacrylate and 90-140 parts of toner into a mixer, performing mixing and stirring, keeping the mixer at 650-750 rev / min, and performing stirring for 5 minutes; b, adjusting the speed of the mixer to 1800-1900 rev / min, then adding 75-85 parts of polyethylene terephthalate, 20-40 parts of polyphenylene sulfide and 25-50 parts of acrylamide sequentially, and performing high-speed dispersion for 30 minutes; and c, after the dispersion, preparing the paint with the fineness of less than 60 microns. The finish paint has the advantages of excellent heat resistance,comprehensive chemical stability and heat resistance, can still work normally below 200 DEG C, and therefore has good stability.

Description

technical field [0001] The invention belongs to the technical field of paint for furniture, and in particular relates to a preparation process of a top paint. Background technique [0002] Traditional acid-cured furniture paint, because it contains volatile organic solvents, such as benzene, affects human health and pollutes the environment. Therefore, most companies no longer use such products. Other types of furniture paints have poor heat resistance and stability, thereby affecting the service life of furniture. In addition, they often have insufficient filling and weak hardness. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a preparation process of a topcoat, which has better heat resistance and stability, aiming at the deficiencies of the above-mentioned prior art. [0004] The technical scheme adopted in the present invention is: a preparation process of topcoat, comprising the following steps, [0005]...
