Problems solved by technology

[0008] However, in the process of preparing automotive coatings, the good condition of the raw materials cannot be guaranteed, so the quality of the finished product cannot be guaranteed, and a drying oven is required to produce automotive coatings, which cannot be used in the case of drying more raw materials. At the same time, the efficiency of raw material drying is guaranteed, and there are defects in the use

Abstract

The invention discloses a preparation method of an anti-oxidation and anti-discoloration water-based automobile coating. The preparation method comprises the following steps of S1, drying raw materials; S2, putting the raw materials obtained in step S1 into a hot press; S3, stirring the raw materials subjected to hot pressing in S2; S4, adding lauryl sodium sulfate, toluene diisocynate, methyl cellulose, tantalum nitride, ammonium polyphosphate, zinc borate, methyl amyl alcohol and nano activated carbon into a reaction kettle; S5, adding raw materials obtained in S3 into the reaction kettle; and S6, grinding the raw materials obtained in S5. The invention further discloses preparation equipment of the oxidation-resistant and color-change-resistant water-based automobile coating. The preparation equipment comprises a shell, and a door body is movably connected to an outer surface of a front end of the shell. The preparation method and equipment of the oxidation-resistant and color-change-resistant water-based automobile coating are improved at the same time, so that the defect of a finished product caused by poor compatibility of multiple components is avoided, the quality control effect is good, the drying efficiency of the raw materials can be effectively improved, and the use is convenient.

Description

technical field [0001] The invention relates to the field of water-based automotive coatings, in particular to a preparation method and equipment for anti-oxidation and anti-discoloration water-based automotive coatings. Background technique [0002] Automobile coating refers to the coating applied on the body and parts of various vehicles such as cars. It generally refers to the coating and auxiliary materials of new cars and the coating for vehicle repair. Like ordinary coatings, automotive coatings are generally composed of film-forming substances (resin) , additives, pigments, and solvents. At present, my country's automobile sales have continuously exceeded 18 million. The rapid growth of automobile sales has strongly stimulated the continuous development of the automotive coatings business, bringing huge business opportunities to the automotive coatings industry. [0003] Compared with Chinese patent CN201611126722.7, an easy-to-clean automotive coating and its preparat...
