Abstract

The invention belongs to the technical field of electret melt-blown cloth, and particularly relates to a method for preparing an electret melt-blown cloth material based on zeolite and polypropylene.The method for preparing electret melt-blown cloth material based on zeolite and polypropylene comprises the following specific steps of S1, uniformly mixing raw materials: adopting the components inparts by mass of 80-90 parts of polypropylene, 5-10 parts of zeolite and 5-10 parts of electret master batch as the raw materials of the electret melt-blown cloth material, and uniformly stirring andmixing the polypropylene, the zeolite and the electret master batch to obtain a mixture; and S2, melting the raw materials. The zeolite is added, so that the adsorption effect of the melt-blown clothis improved, impurities in air can be better adsorbed when a mask is applied, and the filtering effect is improved. Through the addition of the electret master batch, a good antistatic effect can be achieved, and the situation of static electricity is not liable to occur when the cable is used in winter. The preparation process is simple, and the preparation efficiency is high.

Description

technical field [0001] The invention relates to the technical field of electret melt-blown cloth, in particular to a method for preparing electret melt-blown cloth material based on zeolite and polypropylene. Background technique [0002] Polymer electret is also called electret compound. Polymer material with electret function. Polymer electret can be made into a flexible film, and has excellent charge storage capacity, so it has a promising future. There are two main types. One is highly insulating materials, such as polytetrafluoroethylene and copolymers of ethylene fluoride and propylene, which have a fairly good ability to maintain injected charges. The other is a polarizable polymer, such as polyvinylidene fluoride, which has a permanent dipole moment in the molecule. After this material is polarized, it can maintain its dipole directivity within a certain temperature range. [0003] Zeolite has the properties of adsorption, ion exchange, catalysis, acid resistance...
