Description
Technical Field
The invention relates to an emulsion containing nano cuprous oxide/copper oxide/silver oxide for non-woven fabrics and application thereof, belonging to the technical field of antibacterial and bacteriostatic cloth coating.
Background
With the development of economy and the improvement of the living standard of people, the health care consciousness of people is gradually enhanced, and the requirements on the aspects of health and health environment and the like are higher and higher. In special clothes, insoles, bed sheets and the like, the weather becomes hot or becomes damp, pollution and bacteria are bred, and the spread of a plurality of bacteria can harm the life of people. In addition, SARS and the recently-appearing novel coronavirus pneumonia and other human-borne viruses in 2002 bring great harm to the life and the society of people, and most viruses, particularly the novel coronavirus can be spread through various ways such as droplets, contact and the like. Therefore, the fabrics and cloth with antibacterial function have wide requirements in the fields of medical treatment, health, industry and the like, such as high-barrier-property masks, operating gowns, operating hole towels, protective clothing and other high-barrier-property occasions. At present, some health-care clothes fabrics have a certain antibacterial function, but the antibacterial function is mostly realized through medicine components contained in the fabrics, and the fabrics have weak bonding force with medicines and poor stability.
The nanometer materials such as nanometer cuprous oxide, nanometer copper oxide, nanometer silver oxide and the like can prevent fungal and bacterial diseases, not only has a protection effect on pathogenic bacteria, but also has a treatment and eradication effect. In addition, the copper preparation and the silver preparation have the characteristics of low toxicity, no public nuisance and good environmental compatibility, and are widely applied to antibacterial materials. The Chinese patent applications with publication numbers of CN103572582A (2012) and CN106319925A (2016) propose that nano copper oxide is coated on the surface of a cotton product in an ultrasonic mode, and the prepared non-woven fabric has a good antibacterial and bacteriostatic function, wherein the non-woven fabric coated with the nano copper oxide in CN103572582A is washed with water for 20 times, the nano copper oxide hardly falls off, and the good antibacterial performance is also maintained, and the non-woven fabric coated with the nano copper oxide in CN106319925A is washed with water for 30 times, the nano copper oxide hardly falls off, and the good antibacterial performance is also maintained. Although the cloth is washed for 20 times and 30 times in the two patents, the cloth hardly falls off or falls off to a certain extent, and the antibacterial effect of the cloth is reduced to a certain extent along with the increase of the washing times of the cloth.
Since this year, more and more antibacterial fabrics are widely researched due to the transverse movement of novel coronavirus, and a sterilization port prepared from nonwoven melt-blown fabric prepared from a polypropylene composite material containing nano silver-copper alloy particles is provided in the Chinese patent application with the publication number of CN111528553A, wherein the composite material consists of 95-99% of polypropylene and other nano silver-copper alloy particles, the silver content is 40% -80%, and the balance is copper, and the prepared nonwoven melt-blown fabric has a good antibacterial and bacteriostatic function. Because the compatibility of inorganic substance and high polymer compounds such as PP and the like is poor, the problem that nano silver-copper alloy particles in the composite material are uniformly distributed on non-woven melt-blown cloth is solved, the technical difficulty is high, the requirements on the quality and the surface treatment of nano particles are high, the proportion of silver nano particles is high, the price is high, and the cost for preparing cloth is high.
