Embodiment Construction

[0007] 1. Formula

[0008] No. 10 petroleum pitch (softening point 125-140°C): 34.49, cooked tung oil: 4.23, No. 200 solvent gasoline: 34.28, xylene: 35, manganese naphthenate: 3, cobalt naphthenate: 10.

[0009] Second, the preparation process.

[0010] Heat and dehydrate the petroleum asphalt to remove impurities, then add hot tung oil and drier, then add xylene, and finally add solvent gasoline to adjust the viscosity. The asphalt paint has good adhesion to metal and non-metal, and has the performance of sulfuric acid corrosion resistance.

Abstract

The invention relates to high-grade acid resistant bituminous paint, which is further improvement of common paint. Firstly, petroleum pitch is heated, dehydrated and decontaminated; secondly, hot tung oil and drier are added and then xylene is added; thirdly, solvent gasoline is added for adjusting the viscosity. The paint has certain antiseptic power to gas such as chlorine, hydrogen chloride, sulfur dioxide, ammonia, ammonia oxide and so on and corrosive media such as low-concentration mineral acid solution, caustic alkali and so on, is suitable for indoor engineering, and can be used for protecting steels, concrete and woody elements.

Description

technical field [0001] The invention relates to a paint, in particular to a high-grade acid-resistant asphalt paint. Background technique [0002] The present invention is a further improvement on the common paint. The paint has a certain anti-corrosion ability against corrosive media such as chlorine gas, hydrogen chloride, sulfur dioxide, ammonia, ammonia oxide, low-concentration inorganic acid solution, caustic alkali, etc. at normal temperature, but not It is resistant to petroleum solvents, acetone, oxidants, etc., and will gradually age under long-term outdoor sunlight. It is suitable for interior projects and can be used to protect steel, concrete and wooden components. Contents of the invention [0003] 1.
