Description

Process method for coating release control Technical Field The invention relates to the technical field of coating release control, in particular to a process method for coating release control. Background The paint is named as paint in China, and is divided into oily paint and water paint. The paint is a continuous film which is coated on the surface of the protected or decorated object and can form firm adhesion with the coated object, and is usually a viscous liquid prepared by taking resin, oil and emulsion as main materials, adding pigment, filler and corresponding auxiliary agents, using diluents and the like. The spray coating is mainly used for surface spraying of automobiles, household appliances, buses, airplanes, ships, furniture and the like. The problems of particles, paint orange peel, chromatic aberration, sagging, pinholes and the like on a sprayed coating film can be caused by uneven mixing, oversized molecules, bubbles and the like of the coating and the diluent in the prior art, so that the coating film is unqualified. Thus, there is a need for a process for coating release modulation. Disclosure of Invention The invention aims at providing a process method for coating release regulation. A process for the modified release of a coating comprising the steps of: S1, dispersing for the first time, namely adding a diluting agent into a stirring barrel filled with paint by using a shower; S2, stirring, namely uniformly stirring the diluent and the paint by using a pneumatic stirrer to form diluted paint; s3, detecting the concentration of the diluted paint by using a viscometer; s4, filtering once, namely, filtering the diluted paint with the concentration qualified by detection through a 120-mesh filter screen; s5, standing, namely standing the diluted paint passing through the 120-mesh filter screen for 5 minutes; S6, secondary filtration, namely, filtering the diluted paint after standing through a 180-mesh filter screen; s7, secondary dispersion, namely heating the diluted paint to 38 ℃ by using hot air, and then cooling the paint to normal temperature by using normal-temperature gas, so that the paint release is finished. Further, in step S7, the heating and cooling process is timed by using an intelligent timing lock, and the total heating and cooling time is 45 minutes. Further, in the step S7, the heating time is 20-25 minutes, and the cooling time is 20-25 minutes. Further, in the step S3, when the concentration of the diluted paint is detected to be too low by the viscometer, the paint needs to be added, when the concentration of the diluted paint is detected to be too high by the viscometer, the diluent needs to be added, and then the step S2 is repeated and stirred uniformly until the concentration detection is qualified. In summary, the invention has the following beneficial effects: The coating released by the process method is uniformly mixed, the air bubbles are thoroughly discharged, and the coating has small molecules and is orderly and uniformly arranged. Solves the problems of particles, painted orange peel, chromatic aberration, sagging, pinholes and the like on the sprayed coating film, and improves the coating spraying effect and quality.
