Embodiment 1

[0037] Embodiment 1: The preparation method of the fluororesin emulsion impregnating agent of the present embodiment comprises the following steps:

[0038] ①Prefabricated A mixture, according to the following components and weight ratio:

[0039] 60% fluororesin emulsion 86.5% ~ 98.5%;

[0040] Coupling agent 0.5% to 5%;

[0041] Water-based silica latex with a pH value of 4-6 0.5%-7%;

[0042] FA-series fluorine-containing surfactants 0.5% to 3.5%;

[0043] Mix and stir the above-mentioned A mixture components evenly, A mixture components are stirred in a rotating container, the rotation speed is 60-90 rpm, and the stirring time is 2-5 hours, until there is no sinking and no condensation, stir The pH value of the final A mixture component is kept at 5-6, and then it is ready for use. Among them, the coupling agent is matched with the fluororesin emulsion, and the water-based silicone latex is soft and elastic, resistant to high temperature, and compatible with water;

Embodiment 2

[0078] Example 2, such as figure 1 As shown, the coating equipment includes a dipping tank 1, a heat-fluid heat preservation body 2, and a drum 31, a drum 32, a drum 33, and a drum 34. A drying zone 21 , a second drying zone 22 and a sintering zone 23 .

[0079] The fabric cloth 4 passes through the impregnation tank 1 filled with impregnating agent through the drum drive, and then enters the heat-fluid insulation body 2, and first completes the first-stage drying in the first drying zone 21, and the condition is to dry at 80-120°C 2 to 5 minutes; then complete the second stage of drying in the second drying zone 22 under the condition of 200 to 300°C for 2 to 5 minutes; then complete sintering in the sintering zone 23 under the condition of 360 to 380°C After sintering for 2-5 minutes, the fluororesin-coated base cloth 5 is finally obtained, which has long-term heat resistance up to +260°C, no deformation, no shrinkage, no oil sticking, corrosion resistance, light weight, sm...

Abstract

The invention relates to a method for preparing fluorine resin emulsion. The invention is characterized in that the method comprises the following steps: (1) blending agent A comprising components of fluorine resin, coupling agent, water-based silicone emulsion, FA-serial fluorine-containing surfactant and water is prefabricated; (2) blending agent B comprising components of silicone surfactant, silane coupling agent and water is prefabricated; (3) impregnant is made, and the blending agent A, the blending agent B, acidity pH value modifier, alkalescence viscosity modifier are mixed and stirred evenly until no condensation or precipitation exists in the impregnant, thus the impregnant is made. The invention also discloses a method for fabricating a coated fabric cloth. Compared with the prior art, the invention has the advantages that the obtained fluor resin coat base is used for fabricating a baking pad, a baking tray and a baking basket, has long-term heat-resistant property demonstrated by not deforming at the temperature of 260 DEG C, and does not deform, shrink or absorb oil; moreover, the fluor resin coat base has the advantages of anticorrosion, light weight, smooth surface, self-cleaning property and high temperature flame retardancy.

Description

technical field [0001] The invention relates to a fluororesin emulsion impregnating agent, and also relates to a preparation method of a coated fabric cloth using the impregnating agent. Background technique [0002] Most of the cooking utensils used in the cooking industry in European and American countries are fluororesin (Teflon) pans and non-stick pans that adopt metal product coatings. The use of natural gas or gas in cooking food heating is very easy to cause the bottom of the pot to be overheated and burn out the non-stick fluororesin coating (Teflon) to produce toxic gas, cause food poisoning, affect people's health, and be burned out The pot can not be reused to bring waste of resources and environmental impact. On the other hand, with the rapid development of baking household appliances, it is more convenient for people to cook food, such as microwave ovens, toaster ovens, electric ovens and so on. In order to achieve more hygienic, less time-saving, easier to cl...
