Embodiment 1～6

[0032] A kind of paint film cleaning agent, is prepared by the component of listed mass parts in table 1:

[0033] Table 1

[0034]

[0035] A preparation method of a paint film cleaning agent, comprising the steps of:

[0036] S1. Mix and stir 3-10% co-solvent, emulsifier, accelerator and activator evenly, the stirring speed is 250-300r / min, and the stirring time is 30min;

[0037] S2. Add benzaldehyde, ethylene glycol butyl ether and the remaining co-solvent to the mixed solution in S1 above, and stir until the water-emulsion is transparent without particles, and the paint film cleaning agent is obtained.

Abstract

The invention discloses a paint film cleaning agent and a preparation method and application thereof. The cleaning agent is prepared from, by mass, 10-20 parts of benzaldehyde, 4-8 parts of butyl cellosolve, 0.5-2 parts of an emulsifying agent, 1-2 parts of an activating agent, 0.5-1 part of a thickening agent, 20-42 parts of a cosolvent and 1-2 parts of a promoting agent. The cleaning agent takesbenzaldehyde and butyl cellosolve as main solvents, and a green neutral waterborne paint remover is prepared by matching of components in specific mass parts and is moderate in potential of hydrogen,in a pH range of 7-8, low in volatilization, effective in paint removal and free of corrosion of metal steel. The paint film cleaning agent is environmentally friendly in raw material, simple in preparation, short in paint film removal time, high in paint removal speed, efficient in removal without base material damages and extensively applicable to the field of automobile painting and cleaning,especially cleaning of automobile painting fixture with high requirements on base material precision.

Description

technical field [0001] The invention relates to the technical field of surface coating removal, more specifically, to a paint film cleaning agent and its preparation method and application. Background technique [0002] In the manufacture of automobile painting process, when the paint film reaches a certain thickness during the recycling process of the on-board fixture, the paint film needs to be cleaned for quality and safety. Paint remover, also known as paint film cleaning agent, is currently used to remove the paint film on the surface of the substrate. Its working principle is to destroy the paint through a series of physical and chemical processes such as dissolution, penetration, swelling, stripping and reaction The spatial structure of the film or the bonding force between the paint film and the substrate is used to achieve the purpose of paint removal. The solvent molecules in the paint remover penetrate into the molecular chain segment of the paint film polymer, t...
