Embodiment Construction

[0021] In the specific implementation of the biodegradation accelerator of the present invention, the above-mentioned components can be utilized to carry out batch production, and the source of its raw materials can be:

[0022] Sodium thiocarbamate can adopt the product of Intel Chemical (Inter-chemical) company;

[0023] Diethylamine can adopt the product 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 be produced by Shanghai Chemical Reagent Group;

[0026] The water should be distilled water at 30-40°C.

[0027] The National Synthetic Resin and Plastics Quality Supervision and Inspection Center used the mulch film made of the biodegradation accelerator of the present invention to be 63° C. under ultraviolet irradiation and have a strength of 1000uw / cm 2 Carried out the detection of degradation effect under the condition of condition,...

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 biological materials, and relates to the preparation of raw materials for producing biodegradable mulches, in particular to a biodegradation-stimulating agent for producing controllable biodegradable mulches. 【Background technique】 [0002] Agricultural mulch is an important means of production in agriculture 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 common plastic mulch, a large number of mulch fragments remain in the soil. With the accumulation of plastic film fragments, a large amount of residual plastic film destroys the soil structure, causing soil compaction, poor permeability, and soil fertility decline, which seriously affects the growth and production of crops and reduces crop production. If the residual plastic film per mu exceeds 22kg, the c...
