Description
Technical Field
The invention relates to the technical field of mite removing materials, and particularly relates to a hydrogel type household mite removing material with a cross-linked structure and a preparation method thereof.
Background
Hydrogels (hydrogels) are a class of very hydrophilic three-dimensional network-structured gels that swell rapidly in water and hold a large volume of water in this swollen state without dissolution, and can swell and hold a large amount of water due to the presence of a crosslinked network, the amount of water absorbed is closely related to the degree of crosslinking, the higher the degree of crosslinking, the lower the amount of water absorbed. This property is very much like a soft tissue. The water content in the hydrogel can be as low as a few percent, and can also be as high as 99 percent. The gel is neither a completely solid nor a completely liquid in its aggregate state. The behavior of a solid is that a certain shape and volume can be maintained under certain conditions, the behavior of a liquid is that a solute can diffuse or permeate from a hydrogel, and the hydrogel has various classification methods and can be classified into physical gel and chemical gel according to different hydrogel network bonding. Physical gels are formed by physical forces such as electrostatic interactions, hydrogen bonding, entanglement of chains, etc., are non-permanent, can be converted to a solution by heating the gel, and are also referred to as pseudogels or thermoreversible gels. Many natural polymers are in stable gel state at normal temperature, such as k2 type carrageenan, agar, etc.; among the synthetic polymers, polyvinyl alcohol (PVA) is a typical example, and hydrogels stable at temperatures below 60 ℃ can be obtained by freeze thawing. Chemical gels are three-dimensional network polymers formed by cross-linking chemical bonds, are permanent, and are also called true gels;
mites belong to a class of small animals of the subclass Acarina, the phylum Arthropoda, with body sizes generally around 0.5 mm, some as small as 0.1 mm, and most species less than 1 mm. The mites and spiders belong to the class of arachnids, and the adults have 4 pairs of feet, a pair of tentacles, no wings and tentacles, and are fused into a capsule body which is different from insects.
