Problems solved by technology

[0006] In response to the requirements put forward by the user, the inventor accidentally discovered through a large number of experiments that adding 4-hydroxyphenyl phosphate in the paint remover can solve the problem of volatility at high temperature and can enhance the paint removal effect. The inventor believes that this may be related to 4 -Hydroxyphenyl phosphate has a small molecular weight, but has a high boiling point and is related to three -OH

Abstract

The invention discloses a paint remover. The paint remover contains phenyl 4-hydroxyphosphate, and is particularly prepared from the following components in percentage by weight: 5 to 30% of phenyl 4-hydroxyphosphate, 15 to 25% of high aromatic hydrocarbon solvent oil, 20 to 30% of dichloromethane, 5 to 20% of formate, 5 to 15% of lower alcohol, 0.5 to 2% of a surfactant, 0.5 to 2% of a thickeningagent and 10 to 20% of water. The paint remover is not easy to volatilize, good in paint removing effect and suitable for outdoor paint removing operation.

Description

technical field [0001] The invention relates to a paint remover. Background technique [0002] Paint remover is a kind of old paint film that is mainly used to remove metal, formwork, wood board, furniture, and various supplies. It is a liquid made of aromatic compounds and high-solubility solvents. The osmotic swelling effect of the membrane can achieve the purpose of removing paint and coating on the surface of various substrates. [0003] According to the corresponding standards, the paint stripping operation should be carried out indoors at 23-25°C. However, many paint stripping operations are carried out outdoors, such as aircraft maintenance work. Due to the high ambient temperature in summer and the low ambient temperature in winter, the existing paint strippers volatilize quickly in summer, and the paint stripping effect in winter is not ideal. . Therefore, the user has proposed to the applicant the requirement of developing a paint remover suitable for outdoor op...
