Second step, pulverizing, pulverize dried waste painting slag, and smashing fineness is 500-1000 object dry powder;
3rd step, dissolving, the dry powder of screening adds reactor, and wherein dry powder is 30-35%, adds water paint resin 65-70%, and tune pH value is 7.5-8.5, and then adds anticorrisive agent, and anticorrisive agent accounts for 1% of total amount; Mix the powder breast after making water paint resin and dissolving to be uniformly mixed, be water paint;
4th step, grinding water paint, grind the water paint sand mill of the 3rd step or three-roller;
5th step, filtration water paint, screen pack fineness 450-650 object filter screen;
6th step, toning, will filter water paint, add mill base while stirring, and mixing time is more than 4 hours;
7th step, only to put, after required colourity having been adjusted, in groove, only put more than 72 hours, after degreasing finished product;
The method of B, dryness waste painting slag recovery and reusing and recycling;
The first step, to dissolve, that the waste painting slag without moisture after drying is put into solvation dissolves in groove or reactor, wherein the ratio of solvation and dryness waste painting slag is 60%-65%:35%-40%, finish rear only put 24 hours after, then stir until all dissolve;
Second step, grinding, grind with sand mill or three-roller;
3rd step, filtration, screen pack fineness 450-650 object filter screen;
4th step, adjusting viscosity, viscosity regulates will be guaranteed consistent with the viscosity of former paint;
5th step, toning, by the regeneration of having filtered paint join in reactor, add while stirring solvent borne mill base finished product.
Beneficial effect:
Property of water-bearing waste painting slag and dryness waste painting slag process by the present invention respectively, the physical property utilizing them different and solvability, all turn waste into wealth, and rationally collects, the pollution situation of thorough radical cure waste painting slag in air, soil and working environment thereof is the strong guarantee of environmental improvement.
Detailed description of the invention
The method of waste painting slag recovery and reusing and recycling, comprises property of water-bearing waste painting slag and dryness waste painting slag, it is characterized in that:
The method of A, property of water-bearing waste painting slag recovery and reusing and recycling,
The first step, containing by dry in the drying machine of 45-50 DEG C containing sealing wax slag, be evaporated completely moisture;
Second step, pulverizing, pulverize dried waste painting slag, and smashing fineness is 500-1000 object dry powder;
3rd step, dissolving, the dry powder of screening adds reactor, and wherein dry powder is 30-35%, adds water paint resin 65-70%, and tune pH value is 7.5-8.5, and then adds anticorrisive agent, and anticorrisive agent accounts for 1% of total amount; Mix the powder breast after making water paint resin and dissolving to be uniformly mixed, be water paint;
4th step, grinding water paint, grind the water paint sand mill of the 3rd step or three-roller;
