Formula of nitrile rubber-polyvinyl alcohol double-degradable plastic film and preparation method thereof

Abstract

The invention relates to a formula of a nitrile rubber-polyvinyl alcohol double-degradable plastic film and a preparation method thereof, and relates to the technical field of film production. The nitrile rubber-polyvinyl alcohol double-degradable plastic film is prepared from the following raw materials in parts by weight: 20-30 parts of zinc oxide, 10-15 parts of stabilizing agents, 150-200 parts of butanone, 60-70 parts of nitrile rubber, 60-70 parts of phenolic resin varnish, 60-70 parts of polyvinyl alcohol, 15-20 parts of artemisia sphaerocephala krasch gum, 12-18 parts of hydroxypropyl cellulose, 7-15 parts of pulullan polysaccharide, 13-16 parts of nanometer silicon dioxide, 15-20 parts of zinc stearate, 14-18 parts of oxidized polyethlene wax, 12-17 parts of ethyl silicon oil, 13-15 parts of calcium carbonate, 4-10 parts of glutaric dialdehyde and 13-15 parts of stearyl alcohol. The plastic film prepared through the method disclosed by the invention has biodegradable and photodegradable effects, can effectively solve the problem of white pollution brought by difficult degradation of a common plastic film and is simple in production process, low in cost and favorable to industrialized production.

Description

Technical field: [0001] The invention relates to the technical field of film production, in particular to a formula of nitrile rubber-polyvinyl alcohol double-degradable plastic film and a preparation method thereof. Background technique: [0002] In order to solve the environmental pollution caused by plastic film products such as packaging bags and garbage bags, researchers at home and abroad have been devoting themselves to the development of plastic films that do not pollute the environment. Biodegradable plastic film materials include synthetic materials and natural polymer materials, and natural polymer materials are particularly attractive due to their abundant and renewable resources. However, the molecular chain of nitrile rubber contains a large number of hydroxyl groups, which are easy to form hydrogen bonds inside and outside the molecular chain, so it is insoluble, infusible, and has poor water resistance. its stability. [0003] At present, there have been ma...

Problems solved by technology

[0003] At present, there have been many reports on the research of fully biodegradable plastic films of nitrile rubber-polyvinyl alcohol, but the prepared nitrile rubber-polyvinyl alcohol degradable plastics still have slow degradation speed, nitrile rubber and polyethylene Problems such as poor compatibility and blending of alcohol polymers
