Abstract

The invention discloses a benzoic acid type paint remover. The raw materials are prepared according to the following parts by weight: 20-30 parts of benzoic acid, 15-18 parts of acetophenone, 10-12 parts of benzaldehyde, and 10-15 parts of isopropanol , 3-5 parts of methyl cellulose, 10-12 parts of formic acid, 1-3 parts of paraffin, 2-4 parts of surfactant. The invention is a product with fast paint removal speed, high paint removal efficiency and wide application range. This product can effectively remove various baking paints, self-drying paints and plastic spraying materials, has no corrosion to the substrate and has good flame retardancy. Neither does an open flame burn.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a benzoic acid type paint remover and a preparation method thereof. Background technique [0002] The paint remover is a liquid composed of aromatic compounds and high-solvent solvents. It has a strong ability to dissolve paint films. The paint remover is fast and efficient. It can remove a wide range of coating types and is suitable for alcohol Acid, nitro, polyurea-formaldehyde rubber type vinyl, epoxy, polyester, polyurethane and other paints, exterior wall coatings, powder spraying, coating removal, and strong paint removal ability. Compared with similar foreign products, this product has The paint removal effect is the same, and the paint removal time can be saved by about 20%. [0003] The chemical paint remover in the prior art still has a kind of paint remover that is only suitable for removing several kinds of paint strands, and the paint removal speed is slow, the effi...
