Medical high-temperature water-soluble plastic film and preparation method thereof

Abstract

The invention discloses a medical high-temperature water-soluble plastic film and a preparation method thereof. The medical high-temperature water-soluble plastic film is prepared from the following components in parts by weight: 50-60 parts of polyvinyl alcohol, 8-15 parts of calcium carbonate, 1-4 parts of nanometer titania, 1-2 parts of nanometer antimony trioxide, 7-9 parts of sodium alkyl benzene sulfonate, 1.2-1.4 parts of tetrabutyl titanate, 12-14 parts of xylitol, 60-65 parts of phosphate starch, 2-3 parts of urea, 1-2 parts of magnesium stearate, 13-15 parts of acetyl tributyl citrate, 1-1.5 parts of citric acid, 4-6 parts of 3-hydroxybenzoic acid, 1-2 parts of polyvinyl pyrrolidone and 4-6 parts of water-soluble wax sheets. The plastic film disclosed by the invention has the effects of resisting bacteria and removing odor, is slowly dissolved in water when the temperature exceeds 90 DEG C, has high water solubility, is simple in preparation process, uniform in film-forming thickness and high in flatness and is widely applied to medical washing bags.

Description

technical field [0001] The invention relates to the technical field of medical plastics, in particular to a medical high-temperature water-soluble plastic film and a preparation method thereof. Background technique [0002] Medical packaging materials have a wide range of uses in the medical field. Medical packaging materials must allow the effective penetration of the selected sterilant and apply to other relevant conditions for sterilization methods. Medical packaging materials must also ensure the sterility of the contents before the package is opened. Pharmaceutical packaging materials should also facilitate the aseptic operation when the user opens the package without contaminating the contained items. In addition, the items in the medical sterile packaging materials must also maintain sterility during use. [0003] Generally speaking, the hazards of non-degradable popular plastics to the earth include: 1. The recycling value of plastic bags is low, and they are easy ...

AI Technical Summary

Problems solved by technology

[0003] Generally speaking, the hazards of non-degradable popular plastics to the earth include: 1. The recycling value of plastic bags is low, and they are easy to be scattered in urban streets and tourist areas during use. The plastic structure is stable and not easy to be degraded by natural microorganisms. Long-term inseparability in natural environment

This means that if waste plastics are not recycled, they will become pollutants in the environment, exist permanently and accumulate continuously, which will cause great harm to the environment.

2. Affect agricultural development

3. Waste plastic products discarded on land or in water bodies are swallowed by animals as food, resulting in animal death

4. Landfilling of waste plastics will not only occupy a large amount of land, but also the occupied land will not be restored for a long time, affecting the sustainable use of land

Due to the particularity of the items it packs, medical packaging materials need its packaging materials to meet certain requirements, such as the degradability of materials. Although some research has been done on degradable materials at home and abroad, the degradation performance is still Poor, and if the degradable material is prepared by modification with components with strong degradability, the physical properties of the material often do not meet the requirements
