Abstract

The invention discloses a water-based siloxane coating for an outer surface coating of a non-stick pan. The water-based siloxane coating comprises a single component, the coating is prepared from thefollowing raw materials in parts by weight: 15 to 25 parts of hybrid silane resin; 10 to 15 parts of silicon modified acrylic resin; 5-10 parts of water-based closed polyurethane, 10-15 parts of aminoresin, 30-50 parts of water, 5-10 parts of propylene glycol monomethyl ether, 4-8 parts of diethylene glycol monobutyl ether, 4-58 parts of isopropanol, 0.2-0.5 part of defoamer, 0.2-0.5 part of wetting agent, 1-2 parts of dispersing agent and 0.5-1 part of leveling agent. The water-based system takes water as a main component and a small amount of alcohol ether solvent as an auxiliary component,is environment-friendly and human-friendly, is single-component stoving varnish, is simple in process, only needs a base material according to an existing pretreatment mode, and does not need shot blasting.

Description

technical field [0001] The invention relates to the technical field of non-stick coatings, in particular to a water-based siloxane coating used for coating the outer surface of non-stick pans. Background technique [0002] According to statistics, the total output value of China's domestic non-stick pan surface coatings has reached 2 billion. At present, the outer surface coatings of non-stick pans and utensils used in the market can be divided into three types. Including solvent-based fluorocarbon coatings, solvent-based silicone coatings, and two-component ceramic coatings. [0003] There are a lot of problems in the actual application of the above three coatings, such as: [0004] 1. The solid content of solvent-based coatings currently used is 40%-50%, and 50%-60% are all solvents (xylene, butyl ester, propylene glycol methyl ether acetate, etc.), which are flammable and explosive items. During production and transportation There are major safety hazards in storage an...
