Description

Processing method of loosening agent for powder coating

technical field

The invention relates to the field of paint processing, in particular to a processing method of a powder paint loosening agent used in powder paint processing.

Background technique

Powder coating is a new type of solvent-free solid powder coating, which has the characteristics of no solvent, no pollution, recyclable, environmental protection, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film. Powder coating is different from general coatings. A completely different form, it exists in the state of fine powder, because it does not use solvents, it is called powder coating. However, the powder fluidity, anti-caking and electrification of the existing powder coatings are relatively poor, and the powder coating rate at dead angles when using the existing powder coatings to spray complex workpieces is very low, and the storability of the existing powder coatings Not good.

Contents of the invention

The technical problem to be solved by the present invention is to provide a processing method for a bulking agent for powder coatings. After the bulking agent processed by the method is added to the powder coating, the powder fluidity, anti-caking and electrification properties of the powder coating can be improved, and at the same time It can improve the powder coating rate in dead corners when powder coatings are sprayed on complex workpieces, and can also improve the storage properties of powder coatings.

For solving above-mentioned existing technical problem, the present invention adopts following scheme: the processing method of powder coating loosening agent, comprises the following steps:

Step 1: The mass fraction is 18-22% of nano-scale micronized wax, 8-12% of micro-scale aluminum oxide, 22-28% of micro-scale silicon dioxide, 18-22% of nano-scale trioxide Dialuminum, 22-28% nano-scale silica mixed;

Step 2: mixing and stirring, and performing physical depolymerization, so that the particles of the above raw materials are effectively dispersed and agglomerated are eliminated;

Step 3: Sub-sieving to form finished products.

As preferably, 18% nanoscale micronized wax, 8% micron-scale aluminum oxide, 24% micron-scale silicon dioxide, 22% nano-scale aluminum oxide, 28% nano-scale aluminum oxide are used in the step one. Nanoscale silica.
