Degradable rubber and plastic film with plant peel and shell, fiber, plant powder as raw materials and preparation method thereof

Abstract

The invention belongs to the technical field of biodegradable materials, and particularly relates to a degradable rubber and plastic film and a preparation method thereof. The degradable rubber and plastic film with plant peel and shell, fibers, plant powder as raw materials is characterized in that the film is prepared from raw materials of plant peel and shells, plant fibers, plant powder, high-molecular polymer, a compatibilizing plasticizer, and a functional additive; the weight percents of the raw materials are: 5-15% of plant peel and shells, 4-10% of plant fibers, 30-70% of plant powder, 3-7% of high-molecular polymer, 17-40% of compatibilizing plasticizers, and 1-5% of functional additives; the functional additive is any one of or a mixture of any more than two of a smell removing agent, an insect resist agent, a preservative, and a defoamer, and when any more than two of the above are mixed, the ratio is arbitrary. The degradable rubber and plastic film of the invention has rubber and plastic physical and mechanical performance, and comprehensive functions of general rubber and plastics; the degradable rubber and plastic film prepared by the method has the characteristics of low cost and biodegradability.

Description

technical field [0001] The invention belongs to the technical field of biodegradable materials, and in particular relates to a degradable rubber-plastic film and a preparation method thereof. Background technique [0002] Using agricultural plant resources to make degradable materials as the main raw materials to replace plastic packaging products, making agricultural plant materials a new alternative to petroleum-based resources, not only giving agricultural plants new economic value, improving the economic benefits of agricultural production, To reduce the waste of limited resources (such as oil), but also to control the environmental "white pollution" caused by the extensive use of plastic packaging products. [0003] From the perspective of the development technology of biodegradable materials, using natural polymer materials and polymer derivatives as the main raw materials to produce degradable materials with superplastic function is the main direction of current resea...

Problems solved by technology

However, due to the complicated material preparation process and high processing cost of this kind of degradable materials, the material is expensive, and at the same time, it lacks the comprehensive utilization of other renewable resources, so it cannot widely replace plastics in market applications.

[0006] 3. Natural polymer type: natural polymer materials and derivatives, such as starch, cellulose, chitin, pullulan, etc., but natural polymer plastics are difficult to process directly due to the existence of materials (generally, casting methods are used to form films) ), the film has disadvantages such as poor weather resistance, low strength, and unstable film quality, and has not yet reached the stage of practical application.
