Ceramic sol modified polyether-ether-ketone paint and preparation method thereof

Abstract

The invention discloses ceramic sol modified polyether-ether-ketone paint and a preparation method thereof. The invention aims at providing safe, environment-friendly, oleophobic and hydrophobic water-based paint and manufacturing and spray coating methods thereof. The ceramic sol modified polyether-ether-ketone paint is prepared from prime coat paint, floating coat paint and surface coat paint, wherein the prime coat paint is prepared from all the following ingredients in mass fraction: 5 to 30 parts of ceramic sol, 5 to 15 parts of alkoxy silane, 5 to 30 parts of polyether-ether-ketone matter, 2 to 20 parts of fluroresin, 5 to 20 parts of powder filler, 1 to 15 parts of pigment filler and 10 to 40 parts of solvent; the floating coat paint is prepared from all the following ingredients inmass fraction: 5 to 30 parts of ceramic sol, 5 to 15 parts of alkoxy silane, 10 to 40 parts of fluroresin, 2 to 15 parts of powder filler, 1 to 15 parts of pigment filler and 20 to 50 parts of solvent; the surface coat paint is prepared from all the following ingredients in mass fraction: 40 to 60 parts of fluroresin, 30 to 50 parts of solvent, 0.2 to 2 parts of pearl powder and 1 to 5 parts of aid. The ceramic sol modified polyether-ether-ketone paint disclosed by the invention is mainly applied to paint production.

Description

technical field [0001] The invention relates to an inorganic material surface treatment process, in particular to a ceramic sol modified polyether ether ketone coating and a preparation method thereof. Background technique [0002] In daily life, people use fluorine coatings on the surface of various electric cooker inner tanks, pressure cooker inner tanks, cooking utensils and other electric heating appliances. A new type of coating material that is modified and processed on the basis of resin. The superior coating performance of fluorocarbon coatings comes from the structure of F-C bond. Fluorine is the element with the most electronegativity, its atomic radius is very small, the C-F bond formed is extremely short, and the bond energy is large. The fluorine atoms are closely arranged around the polymer carbon chain, which plays a good protective role and endows fluorine-containing polymers with excellent properties. Excellent solvent resistance, oil resistance, weather r...

Problems solved by technology

However, the mechanical properties of conventional fluororesin coatings are relatively poor, the mechanical properties are not good, and the coating hardness is low (only 1-2H), and the wear resistance is poor.

The conventional improvement method is to add inorganic wear-resistant powders such as silicon carbide to the paint, but these wear-resistant powders only play a filling role in the paint alone, and do not form a firm bond with the paint molecules, which is The effect is not ideal
