Abstract

The invention discloses a production technology of a composite material prepared from degradable PVA non-woven fabric. According to the production technology, the PVA non-woven fabric and a PVA colloidal solution serve as raw materials. At least one face of the PVA non-woven fabric is soaked into the PVA colloidal solution, and the mass fraction of PVA in the colloidal solution is controlled to be 10-30%. When the non-woven fabric enters and passes a metal disk box at a certain speed, one side or two sides of the PVA non-woven fabric can be dipped with colloidal sol in the metal disk box, when the PVA non-woven fabric moves to a scraper, the redundant PVA colloidal solution is scraped away through the scraper, and the PVA non-woven fabric dipped face and the PVA non-woven fabric are composited through grinding, drying and cooling operation. The prepared composite material has very good obstructing performance on liquid and solid and good permeability to gas and is resistant to abrasion and tearing. The composite material can serve as raw materials of disposable medical treatment and public health protective articles.

Description

technical field [0001] The invention relates to the technical field of preparation of composite materials, in particular to a degradable non-woven fabric impregnated composite process and materials obtained by the preparation process. Background technique [0002] With the enhancement of people's awareness of environmental protection, in response to the deterioration of the ecological environment and the harm to human health, suggestions on eliminating pollution and reducing harmful products, including the treatment of white pollution, have been put forward internationally. Developed countries such as Europe, the United States, and Japan have successively legislated or banned "short-term use" non-degradable plastics, and increased investment in research on degradable plastics, promoting the use and promotion of degradable plastics. As a novel green packaging material, water-soluble plastic packaging film is widely used in the packaging of various products in Europe, America,...
