Problems solved by technology

In addition, in order to prevent the coating from falling off, oil paint or silicone paint is commonly used to coat the pot, but its non-stickiness, high temperature resistance and wear resistance are all very poor.
In addition, oil-based paints use organic solvents as diluents or dispersion media, which are expensive and not environmentally friendly

Abstract

The invention belongs to the field of coating materials, and discloses a PES coating material, which comprises the following raw materials: a water-based PES resin emulsion, a water-based color paste,a fluororesin, a surfactant, water and a filler. The water-based PES coating material is good in constructability, good in adhesive force, low in price, basically free of solvent and low in VOC content, meets the national environmental protection requirement, is basically consistent with oil-based PES coating materials in performance, has good construction property compared with oil-based PES coating materials, and can replace oil-based PES coating materials.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a water-based PES coating and a preparation method thereof. Background technique [0002] Polyethersulfone coatings, also known as PES coatings, are special coatings that use polyethersulfone resin as the main resin. Due to the strong chemical resistance of polyethersulfone resin, general solvents cannot dissolve it, mainly use some solvents with high boiling point and strong solvency, such as some high-strength and highly corrosive solvents such as nitrogen methyl pyrrolidone (NMP) . These solvents have strong solvency, and are corrosive, water-absorbing, and volatilize slowly. Also have at present for preventing that coating comes off, and oil paint or organosilicon coating are commonly used to carry out coating process to pot, but its non-stick property, high temperature resistance and abrasion resistance are all very poor. In addition, oil-based paints use organic solvents as dilue...
