Embodiment 1

[0022] In Example 1, an ecological degradation plastic film, composed of a weight of the following weight: 80 parts of linear low density polyethylene, 10 parts of high density polyethylene, 20 starch, 1 plasticizer and environmentally friendly deworm filler 12 Part.

[0023] Further, the environmentally-deridated filler consists of 40 parts of the following weight: 40 parts of rice husk, 20 copies of calcium carbonate, 50 water and 5 parts of plant source.

[0024] Further, the preparation method of the environmentally-inductorfi filler includes the following steps: mix the rice husk and calcium carbonate, ground powder, then add water and stir well, stand for 12 h at room temperature, after standing, placed in a high temperature furnace, Under the nitrogen atmosphere, calcination of 0.5 h at a temperature of 880 ° C, after cooling, adding a plant source insect agent, mix uniform, disrupted into powder to obtain an environmentally friendly deworm filler.

[0025] Further, the pla...

Embodiment 2

[0033] In Example 2, an ecological degradation plastic film film, consisting of a weight of the following weight: 90 parts of linear low density polyethylene, 15 parts of high density polyethylene, 25 starch, 3 plasticizers and environmentally friendly worms 18 Part.

[0034] Further, the environmentally-inductorous filler consists of 50 parts of the following weight: 50 parts of rice husk, 25 calcium carbonate, and 9 water in water and the plant source.

[0035] Further, the preparation method of the environmentally-induced plug-in filler includes the steps of mixing the rice husk and calcium carbonate, polishing powder, then add water and stir evenly, standing for 24 h at room temperature, after standing, placed in a high temperature furnace, At a temperature of the nitrogen atmosphere, 1 h is calcined at a temperature of 900 ° C, after cooling, the plant source insect agent is added, mixed uniform, broken into powder, and obtain an environmentally friendly deworm filler.

Embodiment 3

[0044] In Example 3, an ecological degradation plastic film film consists of 85 parts of the following weight: 12 parts of linear low density polyethylene, 12 parts of high density polyethylene, 2 starch, 2 plasticizers and environmentally friendly worms 16 Part.

[0045] Further, the environmentally-inductive filler consists of 45 raw materials of the following weight: 2 of rice shells, 22 calcium carbonate, and 7 water in water and 7 parts of plant source.

[0046] Further, the preparation method of the environmentally-inductorfi filler includes the following steps: mix the rice husk and calcium carbonate, ground powder, then add water and stir well, stand for 18h at room temperature, after standing, placed in a high temperature furnace, At a temperature of the nitrogen atmosphere, 0.5 h was calcined at a temperature of 890 ° C, after cooling, the plant source insectic agent was added, mixed uniform, crushed into powder to obtain an environmentally friendly deworm filler.

Abstract

The invention relates to the technical field of plastic mulching films, in particular to an ecologically degradable plastic mulching film which is prepared from, by weight, 80-90 parts of linear low-density polyethylene, 10-15 parts of high-density polyethylene, 20-25 parts of starch, 1-3 parts of plasticizer and 12-18 parts of environment-friendly insect-repelling filler. The ecologically degradable plastic mulching film is simple in preparation method and low in cost, and the cost is low. The plastic mulching film is mainly composed of starch and linear low-density polyethylene, the decomposition effect of the plastic mulching film is good, the environment-friendly insect-repelling filler is also composed of easily-decomposed substances, after the mulching film is broken, calcium oxide and water in the environment-friendly insect-repelling filler can release heat, heat decomposition of the plastic mulching film is facilitated, and the easily-decomposed performance of the plastic mulching film is further guaranteed; therefore, the plastic mulching film is not easy to cause adverse influence on the environment.

Description

Technical field [0001] The present invention relates to the field of plastic floral techniques, and more particularly to an ecological degradation plastic film and a preparation method thereof. Background technique [0002] my country is an agricultural big country and population big country, and agricultural issues are important strategic issues related to the people's livelihood. The ground film is one of the important material materials for agricultural production. The application of ground film technology has greatly promoted the improvement of agricultural production and benefits, driving the changes in agricultural production and the development of agricultural productivity. my country is a ground film cover cultivation. The ground film has covered 40 crops in Xinjiang, Shandong, Shanxi, Inner Mongolia, Heilongjiang, Shaanxi, Gansu, etc., and presents continuous growth. [0003] However, ordinary agricultural film is mostly non-degradable polyethylene film, so many environm...
