Problems solved by technology

[0004] The technical problem mainly solved by the present invention: Aiming at the disadvantages that the current agricultural film is difficult to degrade, which seriously reduces the permeability of the soil, brings great difficulties to farming, sowing and crop growth, and causes serious "white pollution", it provides A bamboo fiber and waste silk nonwoven fabric agricultural film, the method sprays the prepared composite adhesive evenly on the composite fiber of bamboo fiber and waste silk fiber, desulfurizes with sodium hydroxide aqueous solution, and then bleaches, Softening, drying and other treatments, the plant fiber agricultural film prepared by this method can be completely degraded, effectively avoiding the pollution of the residue to the soil, environmental protection and low cost, and can be widely used

Embodiment Construction

[0017] Take 1-2kg of bamboo green strips and put them into a grinder, crush them into small pieces of 5-10cm, put them into an oven at 70-100°C and bake them for 1-3 hours, then manually tear them to extract bamboo hemp, and the obtained bamboo hemp Soak it in a hydrochloric acid solution with a concentration of 0.2-0.4mol / L for 1-3 hours, take it out, and air-dry it naturally, then immerse it in a sodium hydroxide solution with a concentration of 0.3-0.5mol / L for 1-3 hours, then air-dry it naturally Rinse the air-dried bamboo hemp with 10-15% bleaching powder solution for 30-60 minutes, take it out, spray emulsified oil evenly on its surface, put it into a fermentation tank and seal it for fermentation at 28-38°C for 10-15 days, and the fermentation is completed Finally, take it out and rinse it with deionized water until its pH reaches 6-8, then move it into an oven and dry it at 50-60°C, comb it with a comb cutter and cut it short to make bamboo fiber for later use; weigh 5-...

Abstract

The invention relates to agricultural mulching film made of bamboo fiber and waste silk non-woven fabric, and belongs to the field of film. The agricultural mulching film made of the bamboo fiber and waste silk non-woven fabric mainly solves the technical problems that existing agricultural film is difficult to be degraded, permeability of soil is seriously reduced, great difficulties are brought to farming, sowing and growth of crops, and serious white pollution is caused. A preparation method of the agricultural mulching film made of the bamboo fiber and waste silk non-woven fabric comprises the steps that a prepared composite adhesive is evenly sprayed on composite fibers of the bamboo fibers and waste silk fibers, desulfurization is conducted through a sodium hydroxide aqueous solution, bleaching, softening and drying are conducted in sequence, prepared agricultural film which is made of plant fibers can be completely degraded after being used for three months, soil pollution Management of users, information categories, map images and information auditingcaused by residues can be effectively avoided, green environmental protection is achieved, the cost is low, and the agricultural mulching film made of the bamboo fiber and waste silk non-woven fabric can be used and promoted in a large area.

Description

technical field [0001] The invention relates to a bamboo fiber and waste silk nonwoven cloth agricultural mulching film, which belongs to the field of film. Background technique [0002] Most of the mulch films in my country's farmland are plastic monomer polyethylene or other synthetic polymers, which have the characteristics of large molecular weight, stable performance, and difficult to decompose. Mulch film fragments are scattered in the soil due to the difficulty of recycling, which will seriously reduce the permeability of the soil year after year, and bring great difficulties to tillage, sowing and crop growth. Therefore, the development of degradable agricultural mulch film to solve the "white pollution" caused by residual film has become a research hotspot in recent years. The research and development of different types of mulch films has progressed rapidly, and a large number of mulch film products have been tested and achieved good results. Plant fiber mulch films...
