Background
The processing steps of powder coating circulating in the existing market are usually three steps, and all coarse-grained raw materials and related auxiliary agents are premixed; then melting and premixing the raw materials through an extruder, homogenizing all components in the coating in the process, and tabletting and forming; and finally, cutting the formed material sheet into pieces, grinding the pieces into powder by using a mill, and packaging and bagging the powder after screening and grinding to form a product.
Because the content of each component in the powder coating is different, especially the auxiliary agent in the raw material belongs to a small amount of components, the raw materials are simply premixed and then enter an extruder, all the raw materials are hot-melted by the extruder, and because the viscosity of the organic matter component in the raw materials of the powder coating is in a liquid state, the auxiliary agent cannot be uniformly dispersed in the coating by a process means of homogenizing each raw material component through hot-melting extrusion, the particle size of the product prepared by the method is about 35 mu m generally in order to ensure the spraying film-forming effect, and the complete leveling can be achieved only when the film thickness of the coating film is more than 35 mu m. The spraying film thickness of the paint can be controlled to be 10-25 mu m, so that the use of the paint cannot be released in various coating fields, and the environment-friendly property of the powder coating becomes a chicken rib.
In the development direction of producing ultrafine powder coating, research and development institutions and various large enterprises propose two different technical exploration routes aiming at the problem, which are respectively as follows:
1. premixing, melt extrusion, cooling and crushing, and liquid nitrogen cryogenic crushing.
2. Dissolving the formula materials in a solvent, dispersing at a high speed, grinding, and spray drying.
The liquid nitrogen cryogenic crushing has high requirements on production equipment, the industrial production is difficult to realize through the operation, the energy consumption is high, and the production efficiency is low. The spray drying process has the VOC emission problem, and the spray drying is limited by the difficulty in realizing industrial mass production by equipment.
Using organic solvent as carrier, dissolving all materials and stirring them uniformly to implement homogenization, then using spray drying to volatilize organic solvent in the later stage. The problems of the scheme are that the spray drying technology is difficult to realize large-scale production, the energy consumption is huge in the organic solvent volatilization process, and the problems of pollution and the like are prominent.
In the patent (CN 200680032433) it is mentioned that powder coatings are prepared by a mechanical melting process from powder coating particles. Such that the powder particles comprise substantially single substantially spherical particles. The proposal combines the particles of the powder coating into larger particles by a melting-agglomeration method, and theoretically adopts air as a solvent of the powder to realize the melting-agglomeration among different raw material particles, thereby achieving the effect of homogenizing all raw material components. Although the laboratory operation of the technology obtains ideal effect, the laboratory operation is changed into industrial production, the powder is influenced by the increase of the amount of the produced product, the powder is obviously accumulated at the bottom of the tank body under the action of gravity in the stirring process, the heating in the reaction tank is uneven, the raw material powder positioned at the upper end of the stirring paddle cannot be melted or agglomerated, and the raw material powder positioned at the stirring paddle is very easy to generate a large amount of agglomeration.

when the powder coating physical polymerization tank is used for carrying out powder coating polymerization, materials in the tank are driven by the stirring paddle 5 to carry out circular motion in the rotating direction in the tank body, raw material powder which moves along the periphery of the stirring paddle changes the moving direction under the action of the diversion module 8 and is collided and rubbed with the raw materials which carry out circular motion, and raw material particles are mutually fused and agglomerated by the temperature generated by self-friction heating among the raw materials. Because the heat that the powder raw materials produced in the jar is divided into self-friction themogenesis and stirring rake and the frictional themogenesis two parts between the raw materials, consequently, the intensification efficiency that is located jar body hypomere part is higher than upper segment part, according to the powder coating of producing to polymerization temperature's demand, utilize two heat exchange system mutually independent nature, the artifical inflow of adjusting two heat exchange system respectively, make it possess different heat exchange efficiency, offset the difference of jar interior upper and lower two space intensification efficiencies through this efficiency difference, make the inside temperature of jar body 3 maintain required temperature uniformly.
