Embodiment Construction

[0022] The method for recovering and reusing waste paint slag, including aqueous waste paint slag and dry waste paint slag, is characterized in that:

[0023] A, the method for reclaiming and reusing aqueous waste paint slag,

[0024] The first step is to dry the water-containing paint slag in a dryer at 45-50°C to evaporate the water;

[0025] The second step is crushing, crushing the dried waste paint slag, and the crushing fineness is 500-1000 mesh dry powder;

[0026] The third step is to dissolve and screen the dry powder into the reaction kettle, in which the dry powder is 30-35%, add 65-70% of the water-based paint resin, adjust the pH value to 7.5-8.5, and then add the preservative, which accounts for the total amount 1%; Stir to mix the water-based paint resin with the dissolved powder milk, which is the water-based paint;

[0027] The fourth step is to grind the water-based paint, and grind the water-based paint in the third step with a sand mill or a three-roller ...

Abstract

The invention discloses a method for recycling, regenerating and reusing waste paint residues. Water-containing waste paint residues and dry waste paint residues are included. The method comprises a method A for recycling, regenerating and reusing the water-containing waste paint residues and a method B for recycling, regenerating and reusing the dry waste paint residues. The method A comprises the following steps: volatilizing water, smashing the residues into dry powder of 500-1,000 meshes, dissolving into aqueous paint, grinding the aqueous paint, filtering the aqueous paint by a filtering net with the fineness of 450-650 meshes, modulating the color, adding a colorant into the filtered aqueous paint during stirring, stewing for 72 hours, and removing oil dirt to obtain a finished product. The method B comprises the following steps: performing dissolving, grinding, filtering and viscosity adjustment, performing secondary color modulation, adding filtered paint into a reaction kettle, and adding a solvent colorant during stirring to obtain a finished product. The water-containing waste paint residues and the dry waste paint residues are respectively treated; by use of the different physical properties and the dissolving capacities, the water-containing waste paint residues and the dry waste paint residues can be both turned into treasures and can be reasonably collected; the phenomenon that the waste paint residues pollute the air, the soil and the working environment can be completely treated, and the method is a powerful guarantee for environmental treatment.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a method for recycling and reusing waste paint slag. Background technique [0002] The pollution of waste paint slag in the air, soil, water and working environment endangers farmland, irrigation, drinking water and groundwater for humans and animals. The irreversible harm of pollution is well known. [0003] The application number is 200710146302 for the method of reusing industrial waste paint slag, but there is no way to realize it, because waste paint slag is divided into aqueous waste paint slag and dry waste paint slag, which not only involves the change of physical properties, but also requires the improvement of chemical properties. Only by changing can we meet the standard of recycling. Contents of the invention [0004] In order to eradicate the pollution of waste paint slag in the air, soil and its working environment, the present invention recycles the waste paint ...
