Abstract

The invention relates to an additive for improving the appearance of paint and a synthesis method of the additive. The additive comprises the following components in parts by weight: 10-20 parts of surface control agent and 40-70 parts of slow drying solvent. The synthesis method comprises the following steps of: preparing materials, adding 80-90% of slow drying solvent into a dispersing container, slowly stirring for 5-10 minutes, adding the surface control agent, continuously stirring for 10-30 minutes, adjusting the content of the surface control agent into a theoretical value by the residual slow drying solvent, slowly stirring for 10-30 minutes, and filtering, so that the product can be obtained. Compared with the prior art, the additive in the invention can effectively avoid the phenomena of pocks, shrinkage cavities and the like caused by the impurity and the greasy dirt, improve the gloss of a paint film, prolong the leveling time of the paint film, and eliminate the pebbling phenomenon, and the invention belongs to the general grade product, and is also suitable for coating materials in the other industries.

Description

technical field [0001] The invention relates to a paint additive and a synthesis method thereof, in particular to an additive for improving the appearance of paint and a synthesis method thereof. Background technique [0002] With the increasing number of automobiles in my country, the automobile repair market has also developed rapidly. In some medium and small auto repair shops, ① cannot completely isolate the dust and oil stains in the repair environment, which will lead to defects in the repaired paint surface, and even rework in serious cases; ② in terms of scale and equipment, they cannot compete with large Comparable to specialized auto repair shops. ③It not only affects the work efficiency of the manufacturer, but also delays the delivery date, and even adversely affects the reputation of the enterprise. In the fierce market competition in the 21st century, it will bring unfavorable factors to the survival and development of small and medium-sized auto repair shops...
