Abstract

The invention discloses a non-stick coating layer, which is prepared from the following raw materials in parts by weight: 40 to 50 parts of epoxy acrylate, 25 to 32 parts of polyacrylic acid fluorine-containing ester, 25 to 32 parts of poly (vinylidene fluoride-trifluoroethylene), 10 to 15 parts of polytetrafluoroethylene powder, 2.5 to 4 parts of a suspension dispersing agent, 1 to 1.4 parts of aleveling agent and 1.5 to 2 parts of a curing agent. The non-stick coating layer has excellent lubricating performance and excellent non-stick performance, can completely meet the use requirements ofvarious processing molds (such as various plastic demolding, baking molds and papermaking and textile industries), contains no demolding agent (the production efficiency can be improved), and has excellent durability; in addition, no silicone oil is contained, and the product is prevented from being polluted; the adhesive force with a base material is large, the loading capacity is large, the impact resistance is good, the flexibility is good, the comprehensive performance is good, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of paint and its coating, in particular to a non-stick coating and its coating process. Background technique [0002] Coating is a solid continuous film obtained by one application of paint. It is a thin plastic layer coated on metal, fabric, plastic and other substrates for the purpose of protection, insulation and decoration. The paint can be gaseous, liquid, or solid, and the type and state of the paint are usually determined according to the substrate to be sprayed. [0003] Epoxy coatings are generally divided into two types: oil-based epoxy coatings and water-based epoxy coatings. According to the performance, there are generally wear-resistant epoxy coatings and epoxy anti-corrosion coatings. Strict divisions should also include anti-static epoxy coatings and architectural environmental protection coatings. Oxygen decorative paint. [0004] However, the coatings currently used also have the followin...
