Abstract

The invention relates to a coating material as well as a preparation method and application thereof. The coating material comprises the following components in parts by weight: 30-50 parts of hydrogenated styrene-isoprene-ethylene branched isoprene-styrene resin; 5-10 parts by weight of polybutylene terephthalate; 5-20 parts by weight of polypropylene; and 20-70 parts by weight of an auxiliary agent. According to the invention, hydrogenated styrene-isoprene-ethylene branched isoprene-styrene resin and polybutylene terephthalate are introduced into the formula of the coating material at the same time, and are matched with other components in the formula according to a specific proportion, so that the obtained coating material has the characteristics of super softness, scratch resistance, fine and smooth hand feeling, dryness and chemical resistance. Moreover, the raw materials adopted by the invention are environment-friendly and non-toxic raw materials, the recycling rate is high, the production mode is clean and efficient, and no pollution is caused to the environment.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an outer coating and a preparation method and application thereof. Background technique [0002] With the increasing demand for life, the quality requirements for products that come into contact with the human body are also getting higher and higher. For example, earphones that are often in contact with the human body are required to be smooth and delicate, and they are also expected to be able to withstand cosmetics. , and is very soft and easy to store, but it is difficult for the earphone cover material in the prior art to take into account the properties of smoothness, fineness, softness, scratch resistance and chemical resistance. [0003] Therefore, there is an urgent need in this field to develop a cover material with the characteristics of super softness, scratch resistance, delicate hand feeling, dryness and chemical corrosion resistance. Contents of the inve...
