Fireproof fluorocarbon powder coating for aluminum panel curtain walls and preparation method thereof

Abstract

The invention discloses fireproof fluorocarbon powder coating for aluminum panel curtain walls and a preparation method thereof. The fireproof fluorocarbon powder coating for aluminum panel curtain walls comprises, by weight, 300-350 parts of polyvinylidene fluoride, 210-250 parts of polyester resin, 280-350 parts of a flame retardant, 50-70 parts of chlorinated paraffin, 20-30 parts of antimony trioxide, 5-10 parts of nano magnesium hydroxide, 10-30 parts of composite zinc phosphate, 10-15 parts of mica powder, 1.5-2.5 parts of a defoaming agent, 25-30 parts of titanium dioxide, 40-60 parts of triglycidyl isocyanurate curing agent, 40-60 parts of precipitated barium sulfate, 5-10 parts of a leveling agent, and 3-6 parts of wax powder. The fireproof fluorocarbon powder coating for aluminumpanel curtain walls has the advantages that a coating layer of the fireproof fluorocarbon powder coating is imparted flame retardance, heat insulation, fire resistance and good decoration at the premise that excellent weatherability, high light-holding rate, good acid and base resistance, and good aging resistance are ensured, and the fireproof fluorocarbon powder coating is new-generation greenhigh-performance decorating coating.

Description

technical field [0001] The invention relates to the field of powder coatings, in particular to a fireproof fluorocarbon powder coating for aluminum veneer curtain walls and a preparation method thereof. Background technique [0002] Powder coating is a new type of solid powder coating. It has the characteristics of no solvent, no pollution, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film. It can already completely replace liquid fluorocarbon coatings. [0003] Fluorocarbon powder coatings refer to powder coatings with fluororesin as the main film-forming substance, which have particularly superior weather resistance, heat resistance, low temperature resistance, chemical resistance, and unique non-stick and low friction properties. Fluorocarbon powder coatings are widely used in various fields of building profiles, electronics industry, machinery industry, and transportation. [0004] Different from solvent-based coating...

AI Technical Summary

Problems solved by technology

[0004] Different from solvent-based coatings, fluorocarbon powder coatings do not contain volatile compounds (VOC), reduce harm to the human body, comply with ROHS, do not contain toxic heavy metals, are environmentally friendly coatings, and are officially released by the country. Green coating product catalog Approved products, however, the fluorocarbon powder coatings currently on the market have disadvantages such as poor flame retardancy, poor acid and alkali resistance, and poor decoration
