Problems solved by technology

At present, most manufacturers sell the leftover materials as waste products, resulting in a great waste of film. Some manufacturers will use a granulator to directly granulate, but because the raw materials have undergone the heat history and shear history of the molding process Compared with brand-new materials, recycled materials have significantly lower mechanical properties, including tensile strength and impact properties, than brand-new materials, and their appearance quality is not as good as before. The color is yellow and the transparency is reduced, which can no longer meet the production needs of PE gloves. can only be used for other purposes

Embodiment 1

[0018] A recovery and regeneration process of PE glove production waste, including waste recovery, crushing, cleaning and granulation. In the granulation process, the waste is mixed with polyethylene octene co-elastomer (POE), nano-SiO 2、 Antioxidant 1010 is mixed according to the following proportions by weight, and heated for plasticization:

[0019] Scrap 86 copies

[0020] Polyethylene octene co-elastomer (POE) 7.8 parts

[0021] nano-SiO 2 6 servings

[0022] Antioxidant 1010 0.2 parts

[0023] The waste is cleaned and dried. After drying, the water content of the waste is measured at 3%. The heating and plasticizing temperature is set at 210°C, and the plasticizing time is 25 minutes. After cooling and pelletizing, observe the obtained PE particles. The appearance is milky white translucent, Waxy, the incision section is smooth.

[0024] Sampling detection of the regenerated PE granules in this embodiment, the performance results are as shown in Table 1:

Embodiment 2

[0028] A recovery and regeneration process of PE glove production waste, including waste recovery, crushing, cleaning and granulation. In the granulation process, the waste is mixed with polyethylene octene co-elastomer (POE), nano-SiO 2、 Antioxidant 1010 is mixed according to the following proportions by weight, and heated for plasticization:

[0029] Scrap 90 parts

[0030] Polyethylene octene co-elastomer (POE) 4 parts

[0031] nano-SiO 2 5.8 servings

[0032] Antioxidant 1010 0.2 parts

[0033] After the waste is cleaned, it is dried. After drying, the water content of the waste is measured as 4.5%. The heating and plasticizing temperature is set at 200°C, and the plasticizing time is 20 minutes. After cooling and pelletizing, observe the obtained PE particles. Waxy, the incision section is shiny, and the product has a slippery feeling when touched by hand.

Embodiment 3

[0038] A recovery and regeneration process of PE glove production waste, including waste recovery, crushing, cleaning and granulation. In the granulation process, the waste is mixed with polyethylene octene co-elastomer (POE), nano-SiO 2、 Antioxidant 1010 and phosphite antioxidant 168 are mixed according to the following proportions by weight, and heated for plasticization:

[0039] Scrap 90 copies

[0040] Polyethylene octene co-elastomer (POE) 3.8 parts

[0041] nano-SiO 2 5.5 servings

[0042] Antioxidant 1010 0.2 parts

[0043] Phosphite antioxidant 168 0.5 parts

[0044] The waste was cleaned and dried. After drying, the water content of the waste was measured to be 3.8%. The heating and plasticizing temperature was set at 220°C, and the plasticizing time was 15 minutes. After cooling and pelletizing, observe the obtained PE particles. Waxy, the incision section is shiny, and the product has a slippery feeling when touched by hand.

Abstract

The invention relates to a recovery and regeneration process of PE (polyethylene) glove production waste, which comprises recovery, crushing, cleaning and granulation of waste, in the granulation process, polyethylene octylene co-elastomer (POE), nano SiO2, antioxidant 1010 and the waste are mixed, heated and plasticized, the process further comprises a drying process, and the water content of the dried waste is controlled to be 3-4.5%. The process is simple, recycling of resources is achieved, the quality of the waste film can reach or be similar to the quality of a brand new PE raw material through modification reduction of the waste film, and good economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of PE film recycling and processing, in particular to a recycling process for PE glove production waste. Background technique [0002] PE gloves have the functions of anti-oil, water, anti-bacteria, acid and alkali resistance, etc., and are widely used in many fields such as household cleaning, medical examination, scientific research, food, hygiene, and industrial and agricultural protection. PE gloves are made of polyethylene blown film. During the production of PE gloves, there will be a lot of leftovers, accounting for about 60% of the film material. At present, most manufacturers sell the leftover materials as waste products, resulting in a great waste of film. Some manufacturers will use a granulator to directly granulate, but because the raw materials have undergone the heat history and shear history of the molding process Compared with brand-new materials, the mechanical properties of recycled mater...
