Embodiment 1
[0070] (1) Synthetic acrylic water-based resin:
[0071] Process: Add xylene solvent and 20 parts of mixed monomers, pass nitrogen gas, heat up to 100°C, add various monomers and some initiator dibenzoyl peroxide (BPO) dropwise, keep warm for 1 hour, add dropwise Keep the remaining initiator at high temperature (130°C) for 3 hours, measure the conversion rate (99%), remove the solvent, remove the solvent under negative pressure, lower the temperature, add DC-3AD modified polysiloxane surfactant, and add deionized water , stir to disperse, control the solid content, filter and pack for later use. The ratio of the main raw material mixed monomers: 55 parts of methyl methacrylate, 25 parts of methacrylic acid, 5 parts of acrylic acid, 15 parts of 2-ethylhexyl acrylate, and 9 parts of methacrylamide.
[0073] Process: Add 30 parts of polytetrafluoroethylene (PTFE) water-based resin, start stirring, add the de...
Embodiment 2
[0077] (1) Synthetic acrylic water-based resin:
[0078] Process: Add butyl acetate solvent and 30 parts of mixed monomers, blow nitrogen gas → raise the temperature to 100°C → add various monomers and part of the initiator di-tert-amyl peroxide (DTAP) dropwise → keep warm for 1h → Add the remaining initiator dropwise → keep high temperature (130°C) for 3 hours → measure the conversion rate (96%) → desolventize → negative pressure desolventize → lower the temperature → add DP-518 dispersant surfactant → add deionized water → stir Disperse → control solid content → filter and pack for later use. The proportion of the main raw material mixed monomer: 40 parts of methyl methacrylate, 15 parts of methacrylic acid, 3 parts of acrylic acid, 12 parts of 2-ethylhexyl acrylate, and 5 parts of methacrylamide.
[0080] Process: Add 60 parts of polytetrafluoroethylene (PTFE) water-based resin → start stirring, add th...

Abstract
The invention relates to a waterborne fluororesin nonstick coating, which is formed by 40 to 70 portions of modified polyte-trafluoroethylene (PTFE) water base resin, 10 to 30 portions of high temperature resistance pigment, 1 to 5 portions of fluororesin additive, 1 to 5 portions of surfactant and 20 to 40 portions of antiwear filler. The waterborne fluororesin nonstick coating uses synthesis propylene acid water base resin for modifying trafluoroethylene PTFE water base resin, adopts acrylic acid fat second polymerization method and does not use an addition agent, the entire fluorine caprylate compound which is harmful to human body in the modification process; the modified resin forms mosaic and perforating network structure, has good temperature dispersing region, solves the problem of the adhesiveness of the coating and the base material and the problems of baking and cracking, thus improving the hardness of nonstick coating. The NU aqueous fluorine resin of the invention does not stick to coating, can be coated on the surfaces of a microwave oven, an electric cooker, a nonstick pan and an electromagnetic pan, etc. to play the roles of protecting the surfaces from being stuck with food, and causing food and aluminum and other metals to be isolated.
Description
technical field [0001] The invention belongs to the technical field of coatings and production techniques thereof, and relates to a non-stick coating of fluorine-containing resin, more specifically a NU water-based non-stick coating of fluororesin and a preparation method thereof. Background technique [0002] Non-stick coating is a special coating whose coating surface is not easily adhered by other sticky substances or easily removed after adhesion. This kind of coating is widely used in household appliances, cooking utensils, automobiles, machinery, chemical industry and other industries due to its anti-adhesive properties such as extremely low surface energy, small friction coefficient and easy sliding. Since DuPont of the United States successfully developed polytetrafluoroethylene (PTFE) non-stick coatings in 1938, it developed PVDF (polyvinylidene fluoride resin) resin construction fluorine coatings in the 1960s. Fluorine-containing resins with functional groups. Fl...
