Problems solved by technology

The lid of the rice cooker is a main part of the rice cooker, which plays a role in sealing the rice cooker. The lid of the rice cooker is generally made of metal materials and needs to work in a high-temperature steam environment. If it is not treated, It is easy to get rusty. Therefore, in the prior art, the inside of the lid of the electric rice cooker is generally coated with paint. However, the heat resistance of the existing paint is poor, and the fumigation of long-term high-temperature water vapor will greatly reduce Coating life

Abstract

The invention discloses a heatproof electric rice cooker cover inner wall coating, and relates to the technical field of electric rice cooker coatings. The coating is prepared from an organosilicone emulsion, polyol, a dispersant, a wetting agent, a filler, a leveling agent, a film forming assistant, modified montmorillonite containing ethyl cellulose, an antifoaming agent and deionized water. The coating can form a firm, natural, nontoxic and tough film on the inner wall of an electric rice cooker cover, and has good hardness and heatproof property.

Description

technical field [0001] The invention belongs to the technical field of electric cooker coatings, and in particular relates to a heat-resistant coating for the inner wall of a cover of an electric rice cooker. Background technique [0002] An electric rice cooker is a common cooking utensil for cooking rice and porridge. The lid of the rice cooker is a main part of the rice cooker, which plays a role in sealing the rice cooker. The lid of the rice cooker is generally made of metal materials and needs to work in a high-temperature steam environment. If it is not treated, It is easy to get rusty. Therefore, in the prior art, the inside of the lid of the electric rice cooker is generally coated with paint. However, the heat resistance of the existing paint is poor, and the fumigation of long-term high-temperature water vapor will greatly reduce The service life of the coating. Contents of the invention [0003] The purpose of the present invention is to provide a kind of hea...
