Biodegradable coffee-grounds vine-imitating material

Abstract

The invention discloses a biodegradable coffee-grounds vine-imitating material. The biodegradable coffee-grounds vine-imitating material is prepared from the following raw materials in parts by weight: 40-50 parts of polylactic acid, 5-15 parts of polyadipate / butylene terephthalate, 20-40 parts of modified coffee grounds, 5-15 parts of nucleator, 0.5-1 part of crystallization accelerant, 2-5 partsof compatibilizer, 0.1-5 parts of melt strength strengthener, 0.5-2 parts of lubricant, 0.1-0.6 part of anti-aging agent, 0.1-0.6 part of antioxidant and 0.1-0.6 part of anti-ultraviolet agent. According to the biodegradable coffee-grounds vine-imitating material, the vine-imitating material is prepared by adopting the coffee grounds, so that a large amount of waste residues generated by a coffeeindustry are put into effective use, meanwhile, odors of original plastic imitated vines are effectively improved, and the woody sense of the vine-imitating material is enhanced; and the traditionalpolyethylene and polyvinyl chloride are replaced with a biodegradable material, i.e., the polylactic acid, so that the generation of environmental pollution is reduced, and protection of ecological environments is facilitated.

Description

technical field [0001] The invention relates to a novel rattan weaving material, in particular to a biodegradable coffee ground imitation rattan material. Background technique [0002] With the continuous improvement of living standards, people's requirements for the living environment are getting higher and higher, such as adding some green to the office space or interior decoration, so the rattan weaving material, as a traditional weaving material, is favored by consumers. But due to the shortage of natural rattan material supply, many existing products adopt rattan-like materials such as plastics to be woven into rattan-like weaving products to meet market demand. Existing rattan-like materials mostly use plastic rattan, including PE rattan and PVC rattan. Compared with natural rattan, it has a longer lifespan, lower cost, and is easy to take care of. However, it is difficult to degrade after being discarded and pollutes the environment, thus limiting its use. [0003] I...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the environmental pollution problem of rattan-like materials, improve the use value of coffee grounds at the same time, and provide a new type of biodegradable coffee grounds-like rattan materials. This invention uses polylactic acid to replace traditional polyethylene or poly Vinyl chloride is used to make rattan-like materials, and the combination of coffee grounds and polylactic acid realizes high-value utilization of coffee grounds, reduces the cost of polylactic acid materials, and maintains the biodegradability of polylactic acid
