Abstract

The invention provides a medical dental pad aseptic base film and a preparation method thereof. The nano-fiber component of a non-woven fabric comprises PE plastic particles, plant fibers, spider silks, nano sponge, a shell mixed powder material and an additive. The base film has reasonable design and can improve overall hygienic properties of dental pads. In the material, the additive prepared bymixing polyethersulfone, polyether ketone and an ethanol solution can increase tightness between the base film and a dental pad body. Further, addition of plant fibers of cotton seeds, willow seeds,and coconut shell whiskers into the material further increases hygienic properties of the base film, and facilitates decomposition of dental pads after discarding. Further, strength and toughness of the surface of the base film can be increased by spider webs. At the same time, through the action of the mixed powder material of tortoise ventral shells and shrimp shells, strength and hardness of the base film can be increased by calcium carbonate, and healthiness of the base film can be increased.

Description

technical field [0001] The invention mainly relates to the technical field of dental pads, in particular to a sterile base film for medical dental pads and a preparation method thereof. Background technique [0002] At present, due to the gradual improvement of people's living standards, people pay more and more attention to the protection and prevention of teeth, and the frequency of dental remediation is gradually increasing. Dental pads are used to assist the dental restoration work. Since the dental pads need to be placed in the human mouth, there is a great requirement for the hygiene of the dental pads. [0003] Most of the existing dental pads use PE materials to make the basement membrane of dental pads, and PE materials are also in the carcinogenic list published by the International Agency for Research on Cancer of the International Health Organization. Therefore, it is necessary to develop a new dental pad basement membrane. It can realize the overall health dema...
