Problems solved by technology

[0003] Powder coatings have a high usage rate because they do not emit VOC (volatile organic compounds), and are extremely excellent coatings from the perspective of the environment and resource conservation. For example, a thermosetting powder coating composition disclosed in Japan No. 2001-98212 will When the composition is coated on metal raw materials such as galvanized steel sheets and iron sheets, its moisture resistance and corrosion resistance are poor

Embodiment Construction

[0014] The present invention is described further below, and preferred embodiment of the present invention is: the mass ratio of each component of polyester acid glycidol ester antibacterial powder coating described in the present embodiment is:

[0015] 64 parts of polyester resin

[0016] Glycidyl cyanate (TGIC) 4.5 parts

[0017] Barium sulfate 10 parts

[0018] Titanium dioxide 20 parts

[0019] Leveling agent 1 part

[0020] Benzoin 0.5 parts

[0021] Antibacterial agent 2 parts.

[0022] The above formula is prepared according to the conventional coating preparation method. Appearance of the finished coating: uniform, loose, and non-agglomerated; specific gravity: 1.1~1.8 (varies with different types and colors); horizontal fluidity: 18~35mm; particle size distribution: 100% less than 125μm, of which more than 85% are at 60 ~90μm. Under the conditions of powder utilization rate of 100% and film thickness of about 80 microns, the coating rate is 9-12 square meters ...

Abstract

The invention provides glycidol polyether antibacterial powder coating which consists of the following components in parts by mass: 60-70 parts of polyether resin, 4-6 parts of glycidol cyanate (TGIC), 8-12 parts of barium sulfate, 15-25 parts of titanium dioxide, 0.5-2 parts of leveling agent, 0.5-1 part of benzoin and 2-4 parts of antibacterial agent. The formula is prepared by a conventional coating preparation method. By adding polyether resin, the gloss, smoothness and the like of the pure epoxy powder are improved. After modification treatment of nonmetal mineral power, compatibility between inorganic substances and organic substances is enhanced, the dosage of filler is greatly increased, and the weather resistance, storage stability, corrosion resistance, mechanical strength and the like of the epoxy polyether powder are also improved at the same time.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a polyester acid glycidyl ester antibacterial powder coating. Background technique [0002] Epoxy polyester powder coating is a kind of thermosetting powder coating. It is prepared with epoxy resin and polyester resin as the main raw materials, and has their own unique properties, so that the produced coating film has excellent leveling, decorative, mechanical properties and strong corrosion resistance. , mainly used in the surface coating of automobiles, household appliances, metal furniture, instruments, indoor fitness equipment, radiators and other industries. [0003] Powder coatings have a high usage rate because they do not emit VOC (volatile organic compounds), and are extremely excellent coatings from the perspective of the environment and resource conservation. For example, a thermosetting powder coating composition disclosed in Japan No. 2001-98212 will When the comp...
