Waterproof and air-permeable elastic film and preparation method thereof

Abstract

The invention relates to a waterproof and air-permeable elastic film and a preparation method thereof. The elastic film contains the following components: matrix resin, elastomer resin, an antibacterial master batch, an inorganic powder material and an aid. The preparation method comprises the following steps: (S1) crushing the inorganic powder material, adding the matrix resin, the elastomer resin, the antibacterial master batch, and the crushed inorganic powder material into a high-speed kneading machine, stirring, adding the mixture into a double screw granulator, and carrying out granulation, extrusion, grain dicing and cooling, so as to obtain a resin master batch for later use; and (S2) uniformly mixing the resin master batch obtained in the step (S1) with the aid, carrying out internal mixing and plastification so as to obtain a sizing material, filtering, carrying out calendering by virtue of a calendering machine, carrying out cooling shaping by virtue of a cooling wheel set,and carrying out clipping and reeling, so as to obtain the elastic film. The prepared elastic film has the waterproof and air-permeable properties and has the advantages of good waterproof and air-permeable properties and antibacterial effect and simple preparation process.

Description

technical field [0001] The invention relates to the technical field of functional films, in particular to a waterproof and breathable elastic film and a preparation method thereof. Background technique [0002] A film is a thin, soft, transparent sheet. Made of plastic, adhesive, rubber or other materials. Thin film is scientifically explained as: a two-dimensional material formed by depositing atoms, molecules or ions on the surface of a substrate. [0003] The development and application of antibacterial waterproof and breathable pellets has built a green barrier for the protection of human health, which is of great significance for improving the living environment of human beings, reducing diseases, and protecting the health of the whole people. [0004] New plastics are gradually replacing traditional natural materials, wood and metal materials, and are favored by people for their excellent performance and rich colors. However, the surface of these plastics is easy to...
