Abstract

The invention provides a multifunctional plastic with an anti-microbial effect, an oxidation resistance and a metal-chelating property and a preparation method thereof. The plastic material is mainly prepared from the following raw materials in parts by weight: 6%-10% of active anti-microbial agent, 2%-6% of active antioxidant, 3%-8% of metal-chelating agent and the balance of macromolecule resin base membrane. The modified resin substrate has certain anti-microbial effect, oxidation resistance and metal-chelating property. A novel application material is supplied for the products, such as, electronic cigarette, and the fields, such as, food packaging. The plastic has certain various characteristic functions; on the basis of improvement for the inherent performance of the products, the plastic is endowed with a more practical characteristic; the guarantee period of the products is prolonged and the application thereof is improved, so that the market value is promoted; the original raw material cost is lowered; the market space is expanded and the incoming is increased.

Description

technical field [0001] The invention relates to the field of plastic packaging technology development, in particular to the research and development of an antibacterial, anti-oxidant and metal chelating smoke filtering plastic material for electronic cigarettes. Background technique [0002] Electronic cigarettes, also known as electronic cigarettes, are mainly used to quit smoking and replace cigarettes. It has the same appearance and taste similar to cigarettes, and even has a lot more taste than ordinary cigarettes. It can also suck out smoke, taste and feeling like cigarettes. E-cigarettes were positioned as "tobacco substitutes" and "smoking cessation products" as soon as they came out, which to a certain extent captured the consumption psychology of some cigarette consumers. The appearance of electronic cigarettes is very similar to that of real cigarettes. It simulates the taste of cigarettes, but has no ash and no cigarette butts. This electronic cigarette, which in...
