Abstract

The invention relates to a biological degradable gas-permeable membrane for paper diaper and a preparation method of the biological degradable gas-permeable membrane, and belongs to the technical field of organic macromolecule film. The biological degradable gas-permeable membrane for paper diaper comprises a spunbond nonwoven fabric which is made of natural plant fibers as a raw material, and a membrane layer with polylactic acid PLA as a substrate, wherein the two layers are compounded through thermal pressing; the membrane layer with the polylactic acid PLA as the substrate contains the following components in parts by mass: 50-60 parts of polylactic acid, 40-45 parts of crosslinked polystyrene, 0.5-1.2 parts of a lubricant, 0.01-0.3 part of an antioxidant and 0.1-0.5 parts of color master batch. The biological degradable gas-permeable membrane provided by the invention has certain tensile strength, anti-leakage properties and good air permeability, can be biologically degraded, and is environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of organic polymer films, and in particular relates to a biodegradable breathable film used for paper diapers and a preparation method thereof. Background technique [0002] Diapers are products that can be discarded after one-time use. Compared with traditional diapers, they are more convenient and hygienic, and are more and more popular among young parents. Diapers are generally made of non-woven fabrics, toilet paper, fluff pulp, polymer water-absorbent resin, PE film, rubber bands and other materials. Among them, the PE polymer breathable film is generally used as an anti-leakage bottom film, which requires it to have a certain tensile strength, and at the same time, it has better air permeability under the premise of anti-leakage. [0003] The application number is 201610807650.6, and the patent titled "a high moisture permeability polyolefin microporous breathable membrane" achieves anti-leakage and g...
