Problems solved by technology

[0003] During the recycling process of recycled plastics, there will be many labels, tapes, glues on the plastics, as well as oil stains, dust, etc., which are difficult to remove, which will have a great impact on the subsequent modification of plastics. Influence, will make the performance of the modified plastic particles poor

Abstract

The invention discloses a modifying reprocessing craft for a recycled plastic. A plastic particle produced by modifying the recycled plastic has better qualities of strong, flexibility, wear resistance, oil resistance, flatness, glossiness and the like, and the economic benefit, the social benefit and the environmental protection benefit are highly integrated; the auxiliarie such as a polyvinyl alcohol resin, a modified ceramic fiber, hydrogenated palm oil, zinc stearate and cholamine are added during the steps of crushing and mixing, so that the performances of the produced plastic particle such as strength, wear resistance, degradability and chemical stability are effectively enhanced, the use value of a product is improved, and the environment protection performance is also strengthened.

Description

Technical field: [0001] The invention relates to the technical field of new materials, in particular to a modification and reprocessing process of recycled plastics. Background technique: [0002] As the consumption of plastic products continues to increase, waste plastics are also increasing. At present, my country's waste plastics are mainly plastic films, plastic yarns and woven products, foam plastics, plastic packaging boxes, plastics, daily-use plastic products, plastic bags and agricultural mulching films. These waste plastic products are difficult to decompose naturally, and waste resources, which will have a great impact on the environment. It is understood that in 2011, my country's waste plastic production was about 28 million tons, and in 2012 it was 34.13 million tons. If the storage, transportation and processing of these waste plastics are not properly used and post-processed, the waste plastic raw materials waiting to be processed will definitely damage the...
