Industrial paint film separating agent and application thereof

Abstract

The invention discloses an industrial paint film separating agent and application thereof. The industrial paint film separating agent comprises the following components in percentage by weight: 50-75 percent of organic acid, 2-20 percent of alcohols, 0.5-5 percent of fatty alcohol-polyoxyethylene ether and alkylphenol ethoxylates, 0.5-2.5 percent of an anionic surfactant and 5-25 percent of water. According to the prepared separating agent disclosed by the invention, an acrylic ester paint film and epoxy paint films on the surface of a plastic part can be effectively removed and the damage to the plastic part is avoided. After the paint films on the surface of the plastic part are separated by using the separating agent, the surface of the plastic part is cleaned by using a plastic cleaning agent, so that the plastic part can be directly and continuously used as a spraying or printing substrate. The separating agent is mild in volatilization speed and can be reused.

Description

technical field [0001] The invention belongs to the field of chemical coatings, and in particular relates to an industrial paint film separator and its application. Background technique [0002] With the gradual promotion and use of plastic products, more and more plastic products have entered people's daily life. In the production stage of plastic products, with the increasingly complex processing technology and more and more diverse appearance requirements, the coating used on the surface Layers are becoming more and more diverse, and the defective rate of the products brought is also higher and higher. In order to improve the living space of the production factory, the handling of defective products is gradually placed in front of each production company. Using methods such as manual eradication to remove the old paint film not only consumes manpower and material resources, but also damages the surface of plastic products. Under normal circumstances, the plastic parts wi...

[0003] Invention patent CN200510033449.9 discloses a paint remover and its method for removing paint on plastic surfaces. The paint remover is water, alcohols, cellulose, and solubilizing agent sodium hydroxide. Although this type of method can remove plastic parts Paint on the surface, but it needs to be heated to 20-70°C (50°C is better), the heating operation is not conducive to the actual operation of the production line, and the high energy consumption is not conducive to large-scale production in the production workshop

It can enter the human body through multiple channels such as skin, mucous membranes, respiratory tract, and oral cavity. Relevant operators bring great hidden dangers
