Embodiment Construction

[0024] The present invention uses special physical principles to process and regenerate new coatings:

[0025] 1. Obtain paint slag

[0026] Two methods are used to collect waste paint for spray paint

[0027] (1) The air flotation coagulant spray exists in the waste water tank, and the floating or sinking waste paint slag is lifted out and put into a square container.

[0028] (2) The coagulant-free paint slag obtained from the filter partition in the spray booth is put into a square container.

[0029] 2. Pretreatment tank

[0030] Made into 40cm high, 200cm wide and 300cm long, with two cement tanks for soaking, ceramic tiles on the inner surface of the tank, and drainage pipes below, the paint slag obtained in 1. (1) is cut into small pieces of about 0.5kg weight with a knife, put Put into the pretreatment tank, add clear water (accounting for 50% of the tank volume), soak the paint residue by hydrolysis for 3-5 hours, and constantly turn over the paint residue, adjust ...

Abstract

The invention relates to the manufacturing technology of a coating, in particular to the reproductive technology of a waste coating. According to the technical proposal provided by the invention, the reproductive technology of a waste coating comprises: a. gaining paint slags; b. preprocessing; c. stirring and filtering; d. synthesizing novel coating. The paint slags conforming to the requirement after sampling and analyzing are synthesized, when synthesizing, one to two paint slag liquid in put in a vessel and is added with the following additive: 10 to 25 original resins and added with solvent to adjust the proportion of 1 : 1 between the original resins and the solvent; 0.3 to 1.0 anti-settling agent; 3 to 5 color sizing for adjusting the colors and 0.5 to 1 dehydrating agent; the unit is part by weight. The invention can process the waste coating into the coating which can be used again and reduce the waste of the resources and the impact of the waste coating on the environment.

Description

technical field [0001] The invention relates to the production technology of paint, in particular to a recycling technology of waste paint. Background technique [0002] Coating is an organic substance that must be used for surface protection and decoration in the surface engineering industry. It is a precious resource. There are many kinds of coatings used in the surface engineering industry. According to different protective functions and construction conditions, the types and quantities of waste coatings produced It is not the same, the waste paint treatment method and the existence form of the slag are also different. The present invention is mainly aimed at waste coatings synthesized from various drying resins, excluding room temperature drying coatings, powder coatings, electrophoresis coatings, water swimming coatings and self-swimming coatings. [0003] Amino resin paint is a kind of paint with amino resin and alkyd resin as the main film-forming substances, and gen...
