Embodiment Construction

[0021] In the specific implementation of the biological downgrading agent of the present invention, the above-mentioned components can be used to produce ingredients using the existing technology, and the source of the raw materials can be:

[0022] Sodium thiocarbamate can be produced by Inter-chemical Company;

[0023] Diethylamine can be produced by Shanghai Linger Chemical Co., Ltd.;

[0024] Acetone can be produced by Nanjing Chemical Reagent Co., Ltd.;

[0025] Carbon disulfide, ferric chloride and nickel chloride can use products produced by Shanghai Chemical Reagent Group;

[0026] The water should be distilled water at 30~40℃.

[0027] The National Center for Quality Supervision and Inspection of Synthetic Resins and Plastics tested the ultraviolet radiation temperature of the mulch made of the biological drop promoter of the present invention at 63°C and the intensity of 1000uw / cm 2 The degradation effect was tested under the conditions of, and the test results are:

Abstract

The invention relates to preparation of a raw material for producing a biodegradable mulch film, in particular to a biological degradation accelerating agent which comprises the following components in percentage by weight: 12-12.5% of sodium dithiocarbamate, 18.5-22% of diethylamine, 10-12% of acetone, 5-8% of carbon disulfide, 15-18% of iron chloride, 12-14% of nickel chloride and 28-30% of water. The invention has the advantages that polyethylene molecule branched chains can be increased to enable the mulch film to be swallowed by microbes in the set time to form CO2, H2O and humus which are finally and thoroughly degraded by biologies; biodegradable mulch films capable of meeting different climate and soil environments in various regions and requirements of different crops in the period of preservation of heat and soil moisture can be manufactured, and the mulch films can be degraded in the designed life without influencing the planting of crops of the next season; and the invention builds a good foundation for producing the biodegradable mulch films.

Description

【Technical Field】 [0001] The invention relates to the field of biomaterials, and relates to the preparation of raw materials for the production of biodegradable mulch films, and specifically, is a biological downgrading agent for producing adjustable and controllable biodegradable mulch films. 【Background technique】 [0002] Agricultural mulch is an important agricultural production material after seeds, fertilizers and pesticides. The mulch film has a good effect of increasing temperature and keeping moisture, and can greatly increase the yield of crops. However, with the large-scale use of ordinary plastic mulch, a large number of mulch fragments remain in the soil. With the accumulation of mulch film fragments, a large amount of residual mulch film destroys the soil structure, causing soil compaction, poor permeability, and reduced soil fertility, which seriously affects the growth and production of crops, and reduces crop production. If the residual mulch film per acre exce...
