Abstract

The invention discloses an alkaline paint remover and a preparation method thereof. The alkaline paint remover comprises the following components in part by weight: 30 to 40 parts of sodium hydroxide, 20 to 30 parts of benzyl alcohol, 5 to 8 parts of water-soluble cellulose, 1 to 3 parts of alkylphenol polyoxyethylene, 1 to 3 parts of benzotriazole, 3 to 6 parts of dimethyl maleate, 1 to 3 parts of polyethylene glycol and 10 to 15 parts of water. The alkaline paint remover is low in cost and toxicity, high in paint removing speed and environment-friendly and sewage is easy to discharge and treat. Different raw materials, proportioning ratios and preparation processes are adopted, so that the alkaline paint remover is safely used, the paint removing effect is enhanced, the using period is prolonged, the working efficiency is effectively improved, and the production cost is obviously saved.

Description

technical field [0001] The invention belongs to the field of paint remover, and relates to an alkaline paint remover and a preparation method thereof. Background technique [0002] In some hardware production factories, due to the needs of the process, the workpiece needs to be protected so as not to affect the next process, so it needs to be protected by painting, and the paint must be removed after the next process is completed; there is another process, because The workpiece needs to be decorated and painted, and the defective products produced after painting need to be stripped and then reworked. For this process, acid stripping is used, and acid stripping is more dangerous and easy to cause personal injury. [0003] Paint stripping is one of the important processes in surface treatment. Various paint strippers have emerged in recent years. The traditional organic paint strippers are mainly dichloromethane paint strippers. Due to the continuous improvement of environmen...
