Production method of nonstick utensil

Abstract

The invention relates to a production method of a nonstick utensil. The method includes the steps of: conducting surface purification treatment on a base material for manufacturing the nonstick utensil; coating the surface of the base material with a high temperature resistant nonstick paint; and processing the base material into the nonstick utensil. Specifically, the nonstick paint is prepared by: adding modified 609 epoxy resin liquid, organic silicon resin, phenyl amino resin, acetal amino resin and a coupling agent into a paint mixing kettle, starting the little, and controlling the stirring rotation speed at 800-1000RPM; adding a pearlescent matrix, polytetrafluoroethylene powder and epoxy carbon black pulp under stirring, then increasing the dispersion rotation speed to 1000-1500RPMuntil the fineness meets the requirement; after the fineness meets the requirement, controlling the stirring rotation speed at 500-800EPM, adding premixed blended pulp of coating aluminum silver pulpand PMA, and using n-butanol and cyclohexanone to adjust the paint viscosity. The nonstick utensil produced by the method provided by the invention has the advantages of no toxicity, high temperatureresistance and good nonstick performance.

Description

technical field [0001] The invention relates to a method for manufacturing utensils, in particular to a method for producing non-stick utensils. 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 temperature (300°C) to form a film, wh...

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
