Problems solved by technology

This is indeed an effective solution to the odor problem in the short term. However, with further research, it has been found that the duration of the fragrance of the slush plastic skin prepared by directly adding flavor to the slush plastic material formula is often short and not long enough. Long lasting

Abstract

The invention relates to long-acting fragrant polyvinyl chloride slush molding powder and application thereof, and the raw material formula of the long-acting fragrant polyvinyl chloride slush molding powder comprises the following components in parts by weight: 100 parts of polyvinyl chloride resin, 70-140 parts of a plasticizer, 3-15 parts of a stabilizer compound, 5-15 parts of an anti-caking agent and 1-3 parts of a long-acting fragrant compound, wherein the long-acting fragrant compound is a compound of cyclodextrin and essence. Compared with the direct addition of essence, the long-acting fragrant compound added in the invention can prolong the lasting time of fragrance from 3 months to 6 months or more, does not affect the atomization and VOC of the final product, and does not need to change the existing production equipment and production process.

Description

technical field [0001] The invention belongs to the field of automotive interior skins, and relates to a plastic slush powder, in particular to a formula, a preparation method and an application of a long-acting fragrance polyvinyl chloride slush plastic powder. Background technique [0002] The problem of new car odor, as the most complained problem by Chinese consumers, has become the focus of the auto industry that needs to be solved urgently. In this regard, major automobile OEMs have continuously introduced and improved relevant standards to strengthen control. At the same time, industry standards are also brewing. In principle, new car odors are mainly small odor molecules released from interior trim materials. When these small odor molecules exceed their odor threshold, people can perceive the corresponding odor. [0003] Automotive dashboard assembly, as an important part of automotive interior parts, especially the instrument panel skin that has the most contact w...
