Problems solved by technology

[0005] The technical problem mainly solved by the present invention is aimed at the current shortage of wood resources, and bamboo shoot shells can replace wood, but because the surface of bamboo shoot shells contains a waxy layer, it has poor compatibility with the adhesive components used in board making, and the surface wettability is poor. Low, resulting in the final packaging material will be due to the low internal bonding strength resulting in poor mechanical strength defects, a preparation method for high-strength bamboo shoot shell packaging material is provided

example 1

[0027] Weigh the bamboo shoot shells and wash them with water for 3 times, and place them flat on the packing plate in the adsorption tower, then cover the surface of the bamboo shoot shells with a layer of zeolite powder with a thickness of 3 mm, and pass into the adsorption tower with a temperature of 200 ° C from the bottom of the adsorption tower. Superheated steam, control the feeding rate of 1L / min, continue feeding and adsorption treatment for 30min; after the adsorption treatment is completed, take out the dewaxed bamboo shoot shells and zeolite powder in the adsorption tower, dewaxed bamboo shoot shells for later use, and put the zeolite powder and lemon juice and a strength of 10 7The cfu / mL Pseudomonas aeruginosa suspension is mixed according to the mass ratio of 1:1:5, then put into the fermenter, seal the mouth of the tank, and ferment for 7 days at a temperature of 30°C; after the fermentation is completed, take out the fermentation product Put it into a high-pre...

Abstract

The invention relates to a preparation method of high-strength bamboo shoot shell packing materials and belongs to the technical field of packing material preparation. According to the preparation method, firstly through a molecular sieve dewaxing principle, the surface of a bamboo shoot shell is subjected to dewaxing treatment, molecular sieve powder absorbing bamboo wax, lemon juice and bacterial suspension liquid are mixed for fermentation, then fermentation products and nickel boride are mixed and react in a high-pressure reaction kettle to obtain a reinforced material, and then the reinforcing material, urea resin and starch paste are utilized to prepare an adhesive. Then the surface of the dewaxed bamboo shoot shell is subjected to corona treatment, after the adhesive is applied, hotpressing is conducted, and thus the high-strength bamboo shoot shell packing paper is obtained. According to the preparation method, the surface of the bamboo shoot shell is subjected to corona treatment, corona discharge is utilized, low-temperature plasma is generated, thus free radicals are generated on the surface of the bamboo shoot shell, so that crosslinking occurs, the surface of the bamboo shoot shell is coarsened, the wettability to the modified adhesive is improved, the free radicals generated on the surface of the bamboo shoot shell can generate intermolecular adsorption and hydrogen bond adsorption with active groups in the modified adhesive, and the mechanical strength of a plate is improved.

Description

technical field [0001] The invention relates to a preparation method of a high-strength bamboo shoot shell packaging material, which belongs to the technical field of packaging material preparation. Background technique [0002] In recent years, my country's forest resources have become increasingly scarce, and the supply and demand of timber have become unbalanced, and the gap between supply and demand of domestic timber has increased year by year. The shortage of wood resources has restricted the sustainable and healthy development of my country's wood product packaging industry to a large extent. The wood-based wood-based packaging materials used for packaging in my country include plywood, particle board and some other boards. [0003] Bamboo shoot shells are natural shedding of bamboo shoots during growth or a by-product of bamboo shoot processing. About 17.64-22.05 million tons of bamboo shoot shells are harvested in the country every year. Most of this huge biomass re...
