Embodiment 1

[0053] Example 1 300°C high temperature resistant coating

[0054] Recipe one:

[0055] Select the following components in mass percentage: 8810 modified silicone resin (acrylic resin modified silicone resin) 30% (Shanghai Longxu Chemical Co., Ltd.), alkyd resin 28% (Jiangsu Champion Paint Technology Group), xylene 7.8% (Sinopec Yangzi Petrochemical Co., Ltd.), AF300 organic soil 1% (Zhejiang Shunfu Clay Chemical Co., Ltd.), carbon black 2% (Tianjin Baochi Chemical Co., Ltd.), ceramic black 1% (Shanghai Furui Chemical Co., Ltd. company), sericite powder 15% (Lingshou County Yaotai Mica Powder Factory), 1250R brand talc powder 15% (Changxing Dajing New Material Technology Co., Ltd.), silicone defoamer 0.2% (Hangzhou Zhuoli Chemical Co., Ltd. ).

[0056] Formula two (replacing the sericite powder and talcum powder of formula one with slag fine powder of the present invention):

[0057] Select the following components in mass percentage: 8810 modified silicone resin (acrylic r...

Embodiment 2

[0065] Example 2 400°C high temperature resistant coating

[0066] Recipe three:

[0067] Select the following components in mass percentage: 8810 modified silicone resin (acrylic resin modified silicone resin) 40% (Shanghai Longxu Chemical Co., Ltd.), polyurethane resin 18% (Amway Material Technology Co., Ltd.), xylene 7.8% (Sinopec Yangzi Petrochemical Co., Ltd.), AF300 organic soil 1% (Zhejiang Shunfu Clay Chemical Co., Ltd.), carbon black 2% (Tianjin Baochi Chemical Co., Ltd.), ceramic black 1% (Shanghai Furui Chemical Co., Ltd. company), sericite powder 15% (Lingshou County Yaotai Mica Powder Factory), 1250R brand talc powder 15% (Changxing Dajing New Material Technology Co., Ltd.), silicone defoamer 0.2% (Hangzhou Zhuoli Chemical Co., Ltd. ).

[0068] Formula four (replacing the sericite powder and talcum powder of formula three with the slag powder of the present invention): select the following components in mass percentage): 8810 modified silicone resin (acrylic res...

Embodiment 3

[0077] Performance tests were performed on the high-temperature-resistant coatings of formula 1 and formula 2 in Example 1, and the high-temperature-resistant coatings of formula 3 and formula 4 in Example 2, and the results are shown in Table 1 and Table 2. The result shows that the high temperature resistant coating of the present invention has superior high temperature resistance, salt resistance, alkali resistance, salt spray resistance performance compared with the high temperature resistant coating that uses traditional high temperature resistant filler such as mica powder, talcum powder, and has higher Paint film adhesion, paint film hardness.

Abstract

The invention discloses improved high-temperature resistant paint. The improved high-temperature resistant paint comprises solvent, organic silicon resin and / or modified organic silicon resin and high-temperature filler which is superfine slag powder. The high-temperature resistant paint is excellent in high temperature resistance, salt resistance, alkali resistance and salt spray resistance and has larger paint film adhesive force, higher paint film hardness and higher market application value.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to an improved high-temperature-resistant coating. Background technique [0002] High temperature-resistant coatings generally refer to coatings that do not change color or fall off when the temperature is above 200°C, and can still maintain appropriate physical and mechanical properties. High temperature resistant coatings are generally composed of high temperature resistant resins, pigments and fillers, solvents and additives. Since the industrial production of organosilicon, the high-temperature-resistant coatings formulated with its products have been widely used in high-temperature motors, high-temperature reactors, high-temperature pipelines, and electrical insulation. Although silicone high-temperature-resistant coatings have excellent high-temperature resistance; however, due to the different pigments and fillers and formulas selected, the coatings have problems such as ...
