Abstract
The invention discloses a powder coating production method, which comprises the steps of mixing resin, a curing agent, pigment, a degassing agent and a filler in proportion, uniformly mixing, carrying out melt extrusion, cooling, crushing, finely grinding by using an air classifying mill, sieving, and finally curing to obtain the coating.
Description
Technical Field
The invention belongs to the technical field of coatings, and particularly relates to a production method of a powder coating.
Background
The paint consists of film forming matter, pigment/filler, solvent, assistant, etc. During the production of the coating, the solid powdery pigment/filler is uniformly distributed in the paint to form a stable dispersion system through effective processing. The nature and amount of the various components in the coating formulation determines the properties and use of the coating.
As a novel environment-friendly material, compared with the common traditional coating, the powder coating has the characteristics of completely containing no solvent and 100 percent of solid powder, and the existing state of the coating is mainly fine powder without using an organic solvent, so the powder coating is named as the powder coating. As zero discharge of three wastes can be basically realized in the production process of the powder coating, and the film layer endowed by the powder coating has the advantages of high mechanical property, excellent chemical resistance, excellent corrosion resistance, labor intensity reduction and the like. Therefore, the coating is concerned by all countries since birth, and becomes a new favorite of the coating market, in the production process of the powder coating, the curing temperature and time have great influence on the product quality, and most of the powder coatings have too long curing time, too high temperature, high production cost and low production efficiency.
Disclosure of Invention
In order to solve the problems, the invention discloses a powder coating production method, which reduces the curing time and the curing temperature, thereby reducing the production cost and improving the production efficiency.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a powder paint is prepared from resin, solidifying agent, pigment, degassing agent and filler through proportional mixing, fusing, extruding out, cooling, breaking, fine pulverizing, sieving and solidifying.
Preferably, the resin is 100 parts by mass.
Preferably, the curing agent is an organic urea low-temperature curing agent, and the mass part of the curing agent is 6-9.
Preferably, the pigment is titanium dioxide, and the mass part of the pigment is 20-25.
Preferably, the degassing agent is benzoin, and the mass part of the degassing agent is 0.3-0.8.
Preferably, the filler is talcum powder, and the mass part of the filler is 40-50.
Preferably, the curing time is 1-10 min, and the curing temperature is 100-180 ℃.
The invention has the beneficial effects that:
the organic urea low-temperature curing agent adopted by the invention reduces the curing time and the curing temperature, thereby reducing the production cost and improving the production efficiency.
Detailed Description
The present invention will be further illustrated below with reference to specific embodiments, which are to be understood as merely illustrative and not limitative of the scope of the present invention.
A powder coating production method comprises the steps of mixing resin, a curing agent, a pigment, a degassing agent and a filler in proportion, wherein the resin is 100 parts by mass, the curing agent is an organic urea low-temperature curing agent 7 parts by mass, the pigment is titanium dioxide 23 parts by mass, the degassing agent is benzoin 0.4 part by mass, the filler is talcum powder 48 parts by mass, uniformly mixing, carrying out melt extrusion, cooling, crushing, finely grinding by using an air classifying mill, sieving, and finally curing for 9min at the curing temperature of 130 ℃, thus obtaining the coating.
The technical means disclosed in the invention scheme are not limited to the technical means disclosed in the above embodiments, but also include the technical scheme formed by any combination of the above technical features.
