Paint slag regenerating process

Abstract

The present invention is paint slag regenerating process and belongs to the field of waste utilizing technology. The paint slag regenerating process includes the following steps: mixing paint slag with organic solvent, homogenizing and dispersing, vacuum distilling, crushing and filtering, regulating viscosity, and packing the product. The present invention can regenerate paint slag produced during painting to produce paint reach the quality standard of the paint so as to realize the reuse of waste.

Description

technical field

[0001] The invention relates to the field of waste slag utilization, in particular to a method for regenerating paint waste slag. Background technique

[0002] Solvent-based paint usually adopts high-pressure air spraying, high-pressure airless spraying, electrostatic spraying and other construction methods. The primary utilization rate of paint is generally between 50% and 85%. Especially when high-pressure air spraying is used, the utilization rate of paint varies with the shape of the workpiece. There are some differences, but generally not more than 60%. Therefore, during the construction process, a large amount of paint is wasted, a large amount of organic waste residue is produced, and the environment is polluted. Paint waste has become a major burden and problem for manufacturers of automobiles, agricultural vehicles, motorcycles, and household appliances.

[0003] At present, there are reports that special equipment is used for pyrolysis and burning ...
