Technical Field
The invention belongs to the technical field of daily chemical articles, and particularly relates to an anti-contamination washing gel bead and a preparation method thereof.
Background
The water-soluble film is a film obtained by contacting water (H)2O) can be quickly decomposed, belonging to a novel packaging material. The water-soluble film is generally prepared from low-molecular compounds which can be decomposed, denatured and even degraded after contacting water, can replace the original inner and outer packages due to excellent physical and chemical properties and has wide application range, thereby achieving the purposes of greenness, environmental protection, high efficiency and safety, and having the application fields of pesticides, chemicals, daily chemical products and the like.
At present, the PVA water-soluble film is most widely applied, and the PVA water-soluble film replaces the prior internal and external packages, and has the advantages that: 1. the inner film can reduce the chemical residue on the outer package, reduce the probability of the contact person and the user being damaged by the chemical, and reduce the harm to the environment caused by the harmful pollutant residue on the outer package; 2. as an outer package, the use of plastic and glass products is reduced, and the plastic and glass composite material has the advantages of pollution reduction, environmental protection, easy degradation and the like. The PVA water-soluble film is widely applied to daily chemical articles, is mainly used for products which are relatively light in weight and suitable for small-volume packaging, and can meet the washing requirement by single input if high-concentration detergents are packaged to form washing condensation beads, so that the products not only can arouse the interest of consumers, but also have the advantages of convenience, rapidness and the like.
The PVA water-soluble film is used as the outer package of the washing condensation bead, the effects of quickly dissolving in water and releasing detergent during washing can be achieved, but due to the difference of physical and chemical properties of the water-soluble film, stains are easily formed on clothes, a washing machine filter screen, the inner wall of the washing machine and the like, dirty spots are formed, and the problems of blockage, bacterial breeding and the like are caused. Therefore, how to solve the problem of the water-soluble film of the washing condensation beads in the using process becomes a difficult point to be overcome.
Disclosure of Invention
