Problems solved by technology

[0004] For the above-mentioned related technologies, the inventor believes that although the Teflon coating has played the effect of protecting the metal mesh substrate, because the surface energy of the Teflon molecule is low, the Teflon is easy to fall off from the surface of the metal mesh substrate, resulting in Teflon-coated metal mesh has limited service life

preparation example

[0040] The raw materials used in the preparation examples of this application can all be obtained from the market, wherein the bagasse is selected from the bagasse (ground to an average particle size of 80 μm) sold by the Xinlaishun Agricultural Products Waste Management Department of Wuming County, and the acetone is purchased from Nanjing For Zhenmu Chemical Co., Ltd., phosphoric acid is selected from industrial-grade orthophosphoric acid sold by Shandong Hongyunchang Chemical Technology Co., Ltd., and phosphorus oxychloride is selected from industrial-grade phosphorus oxychloride sold by Shandong Anqiang Chemical Co., Ltd.

preparation example 1

[0043] In this preparation example, the carbonization aid is prepared according to the following method:

[0044] (1) 70kg of bagasse with a moisture content of 63% is mixed with 980kg of acetone to obtain a bagasse dispersion;

[0045] (2) Add 12 kg of phosphoric acid to the bagasse dispersion, heat at 58° C. for 2.5 hours, and then evaporate the acetone to obtain the charring aid.

[0046] As shown in Table 1, the difference between Preparation Examples 1-5 lies in the different raw material proportions of the charring aids.

preparation example 6

[0050] The difference between this preparation example and preparation example 1 is that the formula of the charring aid also includes 8 kg of phosphorus oxychloride, and the phosphorus oxychloride is mixed together with the bagasse dispersion in step (2).

[0051] As shown in Table 2, the difference between Preparation Examples 6-10 is that the amount of phosphorus oxychloride is different.

Abstract

The invention relates to the technical field of metal products, and particularly discloses a Teflon coated metal net and a preparation method thereof. The Teflon coated metal net comprises a metal net base body and a Teflon coating, the metal net base body is soaked in an alkali solution, the Teflon coating is formed by heating and curing a film coating solution on the surface of the metal net base body, and the film coating solution comprises the following components in parts by weight: 40-60 parts of Teflon powder, 16-24 parts of persulfate, 120-140 parts of deionized water, and 8-12 parts of an emulsifier. According to the preparation method, the metal net base body is pretreated through the aqueous alkali, the activity of the Teflon powder is improved through the persulfate, the combination degree between the Teflon coating and the metal net base body can be improved, and the service life of the Teflon coating is prolonged.

Description

technical field [0001] The application relates to the technical field of metal products, more specifically, it relates to a Teflon-coated metal mesh and a preparation method thereof. Background technique [0002] Teflon is another name for polytetrafluoroethylene. The hydrogen atoms in the Teflon molecule are all replaced by fluorine atoms, which has the characteristics of corrosion resistance, so it is an ideal material for processing metal surface coatings. [0003] There is a Teflon-coated metal mesh in the related art, which includes a metal mesh substrate and a Teflon coating. The Teflon coating is formed after the coating liquid is heated and solidified on the surface of the metal mesh substrate. The formula of the coating liquid includes The components are as follows in parts by weight: 40-60 parts of Teflon powder, 120-140 parts of deionized water, 8-12 parts of emulsifier, 20-40 parts of binder, and the binder is polyvinyl alcohol. The preparation method of the Tef...
