Description
Technical field
The present invention relates to technical field of coatings, specifically a kind of coil coating waste residue recoverying and utilizing method and utilize this method
The priming paint of the preparation of preparation.
Background technique
In the paint package barrel that client retracts, the paint that pail pack inner wall speckles with accounts for 1% or so, thereby produces a large amount of
Coil coating waste residue, these coil coating waste residue quantity are many, and can produce secondary pollution to environment.
Currently, domestic mainly have 3 kinds of methods, i.e. combustion method, landfill method and reclaiming to the processing of coil coating waste residue
Utilization method.The above two are all very big to the pollution of environment, and especially landfill disposal influences more far-reaching.
As for the third method, traditional recovery and reusing and recycling technique is usually to recycle coil coating waste residue to be mixed
After uniformly, impregnated using a large amount of solvent, paint vehicle is made in dissolution filter, and coating products are further made；Due to first
A large amount of solvent is used, this partial solvent is eventually evaporate into atmosphere, is formed volatile organic matter (VOC), and ring is polluted
Border, and have part coil coating waste residue still cannot be degradable, more filtering residue is had, this part residue still will form
Danger wastes；In addition, technics comparing is complicated in implementation process, production cost is in a disguised form increased, so that paint producer is to volume
The attitude that material coating waste residue carries out recycling and reusing is not positive.
Summary of the invention
The purpose of the present invention one is to provide a kind of method of recovery and reusing and recycling coil coating waste residue.
The purpose of the present invention one is achieved in that
A kind of coil coating waste residue recoverying and utilizing method, characterized in that the following steps are included:
