Problems solved by technology

At present, most of the non-stick pan coatings on the market are mostly Teflon coatings, including PFOA (perfluorooctanoic acid ammonium), which is harmful to the human body. At present, there is no completely environmentally friendly high-temperature resistant non-stick pan coating

Embodiment Construction

[0011] The present invention will be further described below in conjunction with specific examples.

[0012] Add 30kg of TO-3 and 70kg of TO-7 into 600kg of deionized water, heat to 80°C, stir at 400 rpm, and add 300kg of polyamideimide powder to the reaction at a speed of 60kg / hour In the kettle, after adding, keep warm for three hours, cool down, and discharge.

[0013] It has been proved by experiments that the high temperature determines the dissolution rate of the material. The higher the temperature, the faster the dissolution. However, considering the processing cost, 80°C is selected as the ideal heating pre-dissolution temperature.

Abstract

The invention relates to a preparation method of a high-temperature-resistant environment-friendly water-based non-stick pan coating adhesive. The preparation method comprises charging material, increasing temperature, supplementing material, preserving heat and discharging material. The preparation method is characterized by comprising the following steps: adding a surface active agent to deionized water, heating to predissolve, adding an adhesive layer raw material while stirring, preserving the temperature for three hours after addition is complete, cooling and discharging the material. Because the non-stick pan coating adhesive is polyamide imide aqueous solution, polyamide-imide is nonfusible and nonsoluble polymer and is difficult to disperse in water, and then the polyamide imide is emulsified by using the non-ionic surface active agent so as to stably consist in the water. In this way, Teflon harmful to a human body is replaced by the polyamide imide aqueous solution to be used as a non-stick pan coating so as to ensure high-temperature resistance and environment-friendly aquosity of the coating.

Description

technical field [0001] The invention relates to the field of household chemicals, in particular to a method for preparing a high-temperature-resistant and environment-friendly water-based non-stick pan coating glue. Background technique [0002] The relationship between human beings and chemical industry is very close. In modern life, chemical products are inseparable almost anytime and anywhere. From material life such as clothing, food, housing, and transportation to spiritual life such as culture, art, and entertainment, chemical products are required to serve them. . Some chemical products play an epoch-making important role in the history of human development. Their production and application even represent a certain historical stage of human civilization. [0003] The advent of "non-stick pans" has brought great convenience to people's lives. People no longer have to worry about burning meat when they are not careful, and fish fillets sticking to the wall of the pan ...
