Embodiment Construction

[0019] A kind of high temperature resistant powder coating, it is made up of following components, and the weight part of each component is:

[0020] Amount of special high temperature resistant resin 560-650 parts

[0021] TGIC 40-48 servings

[0022] Universal leveling agent 8 parts

[0023] Benzoin 3 parts

[0024] PTFE wax 5-10 parts

[0025] Antioxidant 2-5 parts

[0026] Carbon black 8 parts

[0027] Filling 250-350 parts,

[0028] The TGIC adopts TEPIC produced by a Japanese manufacturer, the polytetrafluoroethylene wax is imported TF1778, the antioxidant is imported antioxidant 626, and the carbon black is 330R of CABOT;

[0029] The manufacturing process is batching-mixing-extrusion-grinding into powder, and the control nodes are as follows:

[0030] It is extruded by a single-screw extruder, and the temperature in the curing section is controlled at 125-130°C;

[0031] Grinding with ACM grading mill, the median particle size is controlled to be 33-38.

Abstract

The invention relates to powder paint and particularly to high-temperature-resistant powder paint. The high-temperature-resistant powder paint consists of the following components in parts by weight: 560-650 parts of special high-temperature-resistant resin, 40-48 parts of TGIC (triglycidyl isocyanurate), 8 parts of a common flatting agent, 3 parts of benzoin, 5-10 parts of polytetrafluoroethylene wax, 2-5 parts of an antioxidant, 8 parts of carbon black and 250-350 parts of stuffing. The high-temperature-resistant powder paint is stable in performance, low in production cost and capable of being kept to be invariant in color for 4 hours at a high temperature of 300 DEG C.

Description

technical field [0001] The invention relates to a powder coating, in particular to a high temperature resistant powder coating. Background technique [0002] With the improvement of people's living standards, the requirements for powder coatings on the market are also diversified. In order to meet people's living requirements, many powder coating factories have developed high-temperature-resistant powder coatings, but the existing high-temperature-resistant powder coatings on the market basically have properties Not stable enough, and the price is relatively expensive. Contents of the invention [0003] In view of the above defects, the purpose of the present invention is to provide a kind of stable performance, low production cost, a kind of high-temperature-resistant powder coating that remains unchanged for 4 hours at a high temperature of 300 degrees Celsius. [0004] The technical scheme that the present invention adopts for this reason is: [0005] A kind of high t...
