The color paste is a relatively universal product in the market at present, and can be used for adding liquid colors such as paint, glue, printing and the like; the pigment is a solid powdery synthetic resin coating composed of solid resin, pigment, filler, auxiliary agent and the like. Unlike common mixed solvent type paint and water paint, its dispersion medium is not mixed solvent and water, but air. The method has the characteristics of no mixed solvent pollution, 100% film formation, low energy consumption and environmental protection. Colorants are of both thermoplastic and thermosetting types. Thermoplastic pigments have poor appearance (gloss and leveling property) and poor adhesion to metals, so the thermoplastic pigments have few applications in the field of automotive coating, and thermosetting pigments are generally used for automotive coating, wherein thermosetting synthetic resins are used as film forming substances, and the resins are melted first in the drying process and then chemically crosslinked and cured to form a flat and hard coating. The paint film formed by the paint can meet the requirements of automobile coating on appearance and various mechanical properties and corrosion resistance.
At present, raw materials are mixed and stirred in the production and processing process, then are prepared into solid through a hot melt coating and evaporating mode, and finally are prepared into the required pigment through a crushing mode, wherein the main production and processing process comprises the steps of mixing, melt extrusion, tabletting cooling, crushing and screening, but the traditional processing process needs to be subjected to melting, solidification and crushing treatment, the treatment steps are complicated, a great deal of time is consumed in the treatment process, and coarse crushing, fine crushing and ultrafine powder separation are needed in the crushing stage, so that the steps are more and the energy consumption is high; in addition, the range of motion of the pigment is large in the crushing process, more gas is mixed, if the gas is not reasonably collected, the powder is scattered around as dust, and the production environment is adversely affected, so that dust removal is needed before discharging, and the gas is exhausted, so that the pigment is stabilized; in view of the above, the conventional pigment processing technology is time-consuming, costly, and generates large dust, which is troublesome to process, and it is necessary to propose an improved technical solution to solve the above problems.
