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 a non-woven fabric and application of the emulsion. The nano cuprous oxide / copper oxide / silver oxide-containing emulsion for the non-woven fabrics comprises the following solid raw material components in 100 parts of a solvent: 3 to 85 parts by mass of nano cuprous oxide / copper oxide / silver oxide, 1 to 40 parts by mass of film-forming resin, 1 to 20 parts by mass of a chain extender, 0 to 2 parts by mass of a dispersant, 0.3 to 2 parts by mass of an emulsifier, 0 to 2 parts by mass of an adhesive, 0 to 5 parts by mass of a curing agent and 0 to 3 parts by mass of an initiator. The nano cuprous oxide / copper oxide / silver oxide-containing emulsion for the non-woven fabric can be applied to the surface of a non-woven fabric base material, and is cured into a film through thermal curing or radiation curing and the like, so that good adhesion performance is achieved for the base material, and the obtained non-woven fabric has excellent antibacterial and bacteriostatic properties and is suitable for preparing masks, surgical gowns, surgical drapes, protective clothing and the like with high barrier requirements.

Description

technical field [0001] The invention relates to an emulsion containing nano-cuprous oxide / cupric oxide / silver oxide used in non-woven fabrics and an application thereof, which 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 their requirements for a healthy environment have become higher and higher. Some special clothes, insoles, bed sheets, etc. will produce pollution and breed bacteria when the weather becomes hot or damp. The spread of most bacteria will endanger people's lives. In addition, SARS in 2002 and the recent novel coronavirus pneumonia and other human-to-human viruses have brought great harm to people's lives and society. Most viruses, especially new coronaviruses, can be transmitted through droplets, contact, etc. Spread in multiple ways. Therefore, f...
