Problems solved by technology

Due to the poor compatibility between inorganic substances and high-molecular polymer compounds such as PP, it is difficult to solve the problem of relatively uniform distribution of nano-silver-copper alloy particles on non-woven melt-blown fabrics in composite materials, which has great impact on the quality of nanoparticles and The surface treatment requirements are relatively high, the proportion of silver nanoparticles is relatively high, and the price is expensive, making the cost of fabric preparation relatively high

Abstract

The invention discloses a nano-cuprous oxide / copper oxide / silver oxide-containing emulsion for non-woven fabrics and an application thereof. The solvent contains the following solid raw material components: 3-85 parts of nano cuprous oxide / copper oxide / silver oxide, 1-40 parts of film-forming resin, 1-20 parts of chain extender, 0-2 parts of dispersant, emulsifier 0.3-2 parts, 0-2 parts of adhesive, 0-5 parts of curing agent and 0-3 parts of initiator, described parts are parts by mass. The present invention is used for non-woven fabrics containing nano-cuprous oxide / copper oxide / silver oxide emulsion, which can be coated on the surface of non-woven fabric substrates, and cured into films by thermal curing or radiation curing, etc., and has good effects on substrates. The obtained non-woven fabric has excellent antibacterial and bacteriostatic properties, and is suitable for the preparation of masks, surgical gowns, surgical drapes, protective clothing, etc. with high barrier properties.

Description

technical field [0001] The invention relates to an emulsion containing nanometer cuprous oxide / copper oxide / silver oxide for non-woven fabrics and its application, and belongs to the technical field of antibacterial and antibacterial cloth coating. Background technique [0002] With the development of the economy and the improvement of people's living standards, people's awareness of health care has gradually increased, and the requirements for health and environment are also getting higher and higher. Some special clothes, insoles, bed sheets, etc., will pollute and breed bacteria when the weather becomes hot or damp. The spread of most bacteria will endanger people's lives. Most viruses, especially the new coronavirus, can be transmitted through droplets, contact and other ways. Therefore, fabrics and fabrics with antibacterial functions have a wide range of needs in medical, health, industrial and other industries such as high-barrier masks, surgical gowns, surgical drap...
