Problems solved by technology

[0004] 2. Teflon tetrafluoroethylene coating must be baked at high temperature (300°C) to form a film, which consumes too much energy and is not suitable for coil coating lines and sheet coating lines.
[0005] 3. The mechanical processing performance of the coating film is poor, but the Teflon coating must be sprayed after the appliance is processed and then pickled and phosphated, which not only increases the cost of the production process but also causes environmental pollution

Abstract

The invention relates to a production method of a high temperature resistant nonstick paint. The method includes the steps of: putting modified 609 epoxy resin liquid, organosilicon resin, phenyl amino resin, acetal amino resin and a coupling agent into a paint mixing kettle, starting stirring and controlling the rotation speed at 800-1000RPM; under a stirring condition, adding a pearlescent basematerial, polytetrafluoroethylene powder and epoxy carbon black pulp, then increasing the dispersion rotation speed and controlling the speed at 1000-1500RPM until the fineness meets the requirements;when the fineness meets the requirements, controlling the stirring rotation speed at 500-800RPM, adding a pre-mixed coated aluminum paste and PMA mixed paste, and using n-butyl alcohol and cyclohexanone to adjust the paint viscosity. The high temperature resistant nonstick paint produced by the method provided by the invention has the advantages of no toxicity, strong adhesion, good machinability, high temperature resistance and nonstick performance.

Description

technical field [0001] The invention relates to a method for manufacturing a coating, in particular to a method for producing a high-temperature-resistant non-stick coating. Background technique [0002] In the food culture of western countries, baking molds with non-stick properties are widely used for food processing, such as bread pans, cake molds, coffee cups, etc. With the continuous development of the national economy and the improvement of people's living standards, the consumption of non-stick utensils in my country will continue to soar. At present, the Teflon coating used internationally and domestically has the following disadvantages when applied as a non-stick coating: [0003] 1. Tetrafluoroethylene, the chemical component of Teflon, is cracked under high temperature to produce highly toxic by-products, fluorophosgene and perfluoroisobutylene, which are banned by the US government; [0004] 2. Teflon tetrafluoroethylene coating must be baked at high temperatu...
