Problems solved by technology

[0003] During the recycling process of waste plastics, there will be many labels, tapes, adhesives 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

Embodiment 1

[0025] A process for recycling and modifying waste plastics, the process steps are as follows:

[0026] (1) Put the collected plastic into the cleaning solution, heat to 60 degrees, and soak for 1 hour;

[0027] (2) Put the plastic and the soaking liquid into the mixer for stirring treatment, the stirring speed is 600r / min, and the stirring time is 20 minutes. Rinse the plastic with a high-pressure water gun;

[0028] (3) Air-dry the rinsed plastic with hot air, put the air-dried plastic into a crusher for crushing, then put the crushed material into a high-speed mixer, add additives, and knead. The temperature is 200 degrees, and the mixing time is 20 minutes;

[0029] The auxiliary agent is composed of the following raw materials in parts by weight: 15 parts of polyvinyl alcohol resin, 5 parts of modified silicon carbide, 3 parts of hydrogenated palm oil, 3 parts of anilinomethyltrimethoxysilane, 2 parts of ethylene bisstearamide -4 parts, 2 parts of zinc stearate, 1 part...

Embodiment 2

[0035] A process for recycling and modifying waste plastics, the process steps are as follows:

[0036] (1) Put the collected plastic into the cleaning solution, heat it to 70 degrees, and soak it for 2 hours;

[0037] The cleaning solution is made of the following raw materials in parts by weight: 150 parts of water, 15 parts of sodium percarbonate, 30 parts of modified melamine, 15 parts of soda ash, 10 parts of alginate, 6 parts of triglyceride, octyl 4 parts of dodecyl alcohol, 3 parts of cyclomethicone;

[0038] (2) Put the plastic and the soaking liquid into the mixer for stirring treatment, the stirring speed is 800r / min, and the stirring time is 30 minutes. Rinse the plastic with a high-pressure water gun;

Abstract

The invention relates to a waste plastic recovery processing technology. Plastic particles produced by modifying waste plastic bottles have good strength, flexibility, wear resistance, oil resistance,flatness, glossiness and the like, and the economic benefit, the social benefit and the environment protection benefit are highly unified. Aids such as polyvinyl alcohol resin, modified silicon carbide, ethylene bis-stearamide, zinc stearate and the like are added into the crushed material mixing step, the strength, the abrasion resistance, the degradability, the chemical stability and the like of the produced plastic particles can be effectively enhanced, so that not only the use value of the product is enhanced, but also the environmental protection performance is enhanced.

Description

Technical field: [0001] The invention relates to the technical field of recycling plastics, in particular to a recycling process for waste 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 environment and ...
