Problems solved by technology

At present, most of the mulch films commonly used in production are artificially synthesized plastics, which are difficult to degrade automatically under natural conditions. After long-term use, the residual mulch film waste will be deposited in the soil planting layer, making the seeds of crops unable to take root and germinate, forming a large amount of white pollution. Great damage to the soil planting environment
The incineration process of plastic often contains a variety of toxic and harmful substances, causing air pollution.
If plastic products cannot be decomposed in time after use, it will not only seriously affect the sustainable use of soil, but also restrict the sustainable development of modern agriculture and the rapid development of modern industry and packaging industry.

Embodiment 1

[0030]A masterbatch that promotes the increase in crop, which can control the rate of degradation speed, including a component of the following weight parts: 10 parts of polyethylene, 10 polyvinyl alcohols, 0.001 parts of the square, 0.001 parts of the rare earth oxide, and the photosensitive agent. 0.00.1 parts of the joint agent, 0.001 part of the crosslinking agent, and 0.001 composite degraded agents. The preparation method is as follows:

[0031](1) First, the coupling agent, the calcium, and polyethylene, stir well, then add the crosslinking agent, photosensitizer, polyvinyl alcohol, heated to 100-120 ° C stirring to complete melting, and then cool down to 20 ° C;

[0032](2) A rare earth oxide and a composite reducing agent were added, heated to 100 ° C, stirred, and the reaction was completed at a material reaction, i.e., the ground film masterbatch.

[0033]The average degradation of the masterbatch made of masterbatch was 1103 days.

Embodiment 2

[0035]A masterbatch that promotes the increase in crop, can control the rate of degradation speed, including 100 parts by weight of the following parts: 100 parts of polyethylene, 100 parts of polyvinyl alcohol, 50 parts of 2000, 0.001 rare earth oxides, 80 photosensitizers , 50 parts of the coupling agent, 0.001 part of the crosslinking agent, 20 composite degraded agents.

[0036]The preparation method is as follows:

[0037](1) First, the coupling agent, the calcium and polyethylene, stir well, then add the crosslinking agent, photosensitizer, polyvinyl alcohol, heating to 100-120 ° C stirring until complete melting, then cooling to 50 ° C;

[0038](2) A rare earth oxide and a composite reducing agent were added, heated to 100 ° C, stirred, and the reaction was completed at a material reaction, i.e., the ground film masterbatch.

[0039]The average degradation of the resulting masterbatch was 71 days.

Embodiment 3

[0041]A masterbatch that promotes the increase in crop, can control the rate of degradation speed, including a component of the following weight parts: 200 parts of polyethylene, 200 parts of polyvinyl alcohol, 100 square alcohol, 100 parts of the rare earth oxide, 100 photosensitive, even 100 parts of the joint agent, 100 parts of the crosslinking agent, 50 parts of the composite degraded agent.

[0042]The preparation method is as follows:

[0043](1) First, the coupling agent, the square solution, and the polyethylene, stir well, then add the crosslinking agent, photosensitive agent, polyvinyl alcohol, heating to 100-120 ° C stirring to completely melting, then cooling to 80 ° C;

[0044](2) A rare earth oxide and a composite reducing agent were added, heated to 200 ° C, stirred, and the reaction was completed to the material reaction, i.e., the masterbatch.

[0045]The average degradation of the masterbatch was 15 days.

Abstract

The invention relates to the field of degradable mulch, and discloses a masterbatch that can increase crop yield and control the degradation rate, comprising the following components by weight: 10-200 parts of polyethylene, 10-200 parts of polyvinyl alcohol, calcite 0.001-100 parts, rare earth oxide 0.001-100 parts, photosensitizer 0.001-100 parts, coupling agent 0.001-100 parts, cross-linking agent 0.001-100 parts, composite degradation agent 0.001-50 parts. The present invention also provides a manufacturing method of the above-mentioned masterbatch. The mulch film prepared from the masterbatch of the present invention can achieve the purpose of increasing production by adjusting the ratio of each component, and can be degraded within 15 days to 3 years, so as to avoid polluting the environment and affecting sustainable planting of soil.

Description

Technical field[0001]The present invention relates to the field of degradable materials, particularly a masterbatch and a manufacturing method thereof that promote the increase in creator, and can control the degradation rate.Background technique[0002]Plastics are a synthetic polymer material for a wide range of applications. But "white pollution" brought about by abandoned plastics is getting more serious. Film is a commonly used agricultural materials. The laying film can effectively reduce the evaporation of soil moisture, drought and rumor, and after the rain, it has the effect of maintaining soil humidity, improving soil temperature, inhibiting weed growth, and effectively improving the survival rate and yield of plant cultivation. Currently, the most commonly used molding plastics is difficult to automatically degrade. It is difficult to automatically degradation under natural conditions, and the residual ground film waste will deposit in the soil planting layer, so that the s...
