Embodiment 1

[0037] First, 65 parts of the raw material polyethylene plastic particles, 37 polylactic plastic particles, 9 starch plastic particles, 3.4 parts of maleic anhydride, 2.6 defoamides, and 1.5 parts of dikyl phthalate. At the same time, the polyethylene plastic particles, polylactic acid plastic particles and starch plastic particles are screened to 80 mesh;

[0038] The polyethylene plastic particles, polylactic acid plastic particles, and starch plastic particles are melted at a temperature of from 190 ° C, and the stirring is mixed, and the maleic anhydride graft compatible agent, defoamer, and octyl phthalate are added to 155 ° C. Stir mixing;

[0039] The feedstock mixed in the above-described T-type die casting was extruded, and the extruded film was cooled by a cooling roller of 1 ° C, and then the film was milled by a flattening device. Film creates wrinkles;

[0040] The film was rinsed by uniformly disposed uniformly provided by the film on both sides, and after the 1.2m h...

Embodiment 2

[0043] First, 75 parts of the raw material polyethylene plastic particles, 39 polylactic acid plastic particles, 8 starch plastic particles, 3.8 maleic anhydride graft compatible agents, 1.8 defoamodulators, and 1.8 dikyl phthalate. At the same time, the polyethylene plastic particles, polylactic acid plastic particles and starch plastic particles are sieved to 120 mesh;

[0044] The polyethylene plastic particles, polylactic acid plastic particles, and the starch plastic particles are melted under 200 ° C at the temperature conditions, and the mixture is added to 155 ° C to add maleic anhydride graft compatibilizer, defoamer, and dictyl phthalate. Stir mixing;

[0045] The feedstock mixed in the above-described T-type die casting was extruded, and the extruded film was subjected to a cooling roll of -1 ° C to cool the film, and then the film was milled by a flattening device. Avoid the formation of pleats;

[0046]The film was rinsed by uniformly disposed uniformly disposed of th...

Embodiment 3

[0049] First, 58 raw material polyethylene plastic particles, 41 polylactic plastic particles, 10 starch plastic particles, 2.3 parts of maleic anhydride graft compatible agent, 3.2 parts of defoamide, and octyl phthalate 1.8 parts. At the same time, the polyethylene plastic particles, polylactic acid plastic particles and starch plastic particles are sieved to 100 mesh;

[0050] The polyethylene plastic particles, polylactic acid plastic particles, and starch plastics are simultaneously stirred at a temperature of 180 ° C, and then add a maleic anhydride graft compatible agent, anhydrutant, and dictyl phthalate. Stir mixing;

[0051] The feedstock mixed in the above-described T-type die casting was extruded, and the extruded film was cooled by a cooling roller of 1 ° C, and then the film was milled by a flattening device. Film creates wrinkles;

[0052] The film was rinsed by uniformly disposed uniformly provided by the film on the upper and lower sides, and then dried after the ...

Abstract

The invention discloses a production process of an environment-friendly degradable plastic film. The production process of the plastic film comprises the following steps of 1, preparing and screening raw materials such as polyethylene plastic particles, polylactic acid plastic particles and starch plastic particles, 2, melting and mixing the raw materials, 3, extruding the raw materials mixed in the step 2 through a casting machine, 4, cooling the film extruded in the step 3, 5, flattening the cooled film through a flattening device, 6, spraying, washing and drying the flattened film, and 7, slitting and rolling the dried film. According to the production process of the environment-friendly degradable plastic film, the production efficiency can be guaranteed, full mixing of raw materials is guaranteed, and what can be guaranteed is that the plastic film is rapidly and fully degraded.

Description

Technical field [0001] The present invention relates to the field of plastic film technologies, and more relate to degradable plastic film technology, in particular, a production process of environmentally friendly degradable plastic films. Background technique [0002] Plastic film is a product that can be common in daily life, which is generally used for parcels or coating layers. Due to large demand for various products, foods, and shopping, it is necessary to increase the use of plastic films. It is guaranteed that the good recovery of the plastic film has also led to plastic pollution under modern society; [0003] Plastic pollution is placed by plastic packaging bags, agricultural film, disposable tableware, plastic bottles such as plastic products, is abandoned into solid waste, causing relief treatment, giving an ecological environment, and landscapes have caused non-negligible pollution; [0004] In response to the problem of plastic pollution, degradable plastics should...
