A kind of degradable decoration material and preparation method thereof

Abstract

A degradable decoration material and a preparation method thereof, the invention relates to the technical field of biodegradation. The raw materials of this material and their parts by weight ratio are: plant source powder 20‑50, polypropylene 10‑30, calcium carbonate 15‑30, plasticizer 1‑8, compatibilizer 2‑5, coupling agent 1 ‑5, catalyst 0.2‑3, activator 0.5‑5, heat stabilizer 0.1‑3, degradation agent 0.3‑5, oxidant 0.01‑5, in the range of 160—275°C, different formula raw materials are blended according to the ratio to form a modified The powdery or powdery polymer after curing is directly fed into a calender or extruder to form a sheet, plate or profile. By adjusting the ingredients, this material can control the length of degradation time, and reduce the impact on the ecological environment through active recycling or natural degradation.

Description

technical field [0001] The invention relates to the technical field of biodegradation, in particular to a degradable decoration material and a preparation method thereof. Background technique [0002] With the rapid development of the petrochemical industry, various types of new materials used in the construction industry and daily life are increasing, especially the demand for temporary buildings or disposable consumables is increasing, and these materials are discarded after use to form mass production Household garbage causes environmental pollution and energy waste, so its degradation treatment has become a hot research topic. Around 1990, biodegradable plastics filled with starch appeared in general-purpose plastics. At the same time, on the basis of photodegradable plastics, new materials with both photodegradation and biodegradation functions filled with starch were developed. The main technical problems of this new type of degradable material are as follows: the deg...

AI Technical Summary

Problems solved by technology

[0003] The invention patent with the publication number CN103012950A discloses a biodegradable plastic containing starch, polypropylene and calcium carbonate, wherein the starch content is low, the degree of biodegradation is not high, and the degradation time is uncontrollable

[0004] The invention patent of authorized notification number CN 1164661C discloses a starch-based biodegradable material with high starch content and good degradation rate. The controllability is poor, and it may deteriorate after a short period of application

[0005] The invention patent of authorized notification number CN 102634073B discloses a starch / polypropylene degradable material, which has a high biodegradation rate, but the degradation time cannot be well controlled, and the starch needs to be modified, the preparation process is complicated, and the application of the material The scope is also relatively narrow, limited to light and thin disposable consumables such as disposable lunch boxes, plastic films, and packaging materials. It cannot be applied to some materials that need to be degraded for a long time.
