Abstract
The invention discloses a method for producing a degradable environment-friendly banana bag through banana stem fiber, and relates to the field of the plant fiber degradable material packaging industry. The production method comprises the following steps of: performing physical modification treatment on banana stem natural plant fiber through dry material preparation, drum type segmenting, high-pressure fiber liquid separation and addition of a biological pulping auxiliary agent into a high consistency refiner in proportion and cleaning banana stem softened and degraded fiber; conveying to a concentrated fiber pulp tank through a concentration inclined screen by an intermediate concentration residue remover, a flow-out type pressure screen, a high and intermediate concentration two-section residue remover and a dust collector; adding the banana stem fiber, amylose, waste paper fiber and a water-proof and moisture-proof auxiliary agent in proportion, neutralizing, stirring, gathering and conveying to a 1800 dryer; hot pressing; forming; and warehousing. No harm or potential harm is caused to the natural environment by the banana bag in a degradation process and by residues after degradation; the banana bag can be completely degraded into an organic fertilizer in eight months in the natural environment; and the ecological environment is effectively protected.

3), the physical modification of banana stem stalk natural plant fibre is handled: the banana stem stalk fiber of 40～50mm length is added biological defibrination auxiliary agent to high dense mill, rub with the hands through 25% concentration mill, direct physical has changed the structure and the surface property of banana natural string.
4), the fiber pulp behind the high dense mill directly gets into stock tank, make biological defibrination auxiliary agent disappear to dive and fiber softening decomposed in 60～120 minutes through stirring at normal temperature;
5), the softening fiber that decomposes of banana stem stalk is cleaned, by in dense scummer, outer-flowing type pressurized screen, height, in dense two sections slagging-off, deduster through concentrating the fiber stock tank of oblique net after concentrated;
6), stir as the composite matrix resin of 40-45% banana stem stalk natural fabric 20-35% waste paper fibre with wherein a kind of 20-25% of biodegradable polysaccharide natural polymers such as starch, shitosan and get into good stock tank.
Add waterproof auxiliary agent 2-3%, moisture-proof auxiliary agent 1-3% when 7), good slurry gets into vacuum forming machine and be transported to 1800 dryers hot-forming can the warehouse-in in storage in back of coming out then.
The present invention has following beneficial effect:
1, because this technology extraction banana stem stalk natural plant fibre is through biological defibrination auxiliary agent the banana stem stalk of 40～50mm length to be rubbed with the hands through 25% concentration mill, direct physical has changed the structure and the surface property of banana natural string.
2, banana stem stalk fiber does not need high temperature, high pressure, if under the normal temperature state, disappeared in 60～120 minutes latent, stir and just can obtain available string;
3, banana stem stalk fiber and starch (or shitosan) the polysaccharide natural polymer neutralization banana bagging that forms degradable material has the application performance that ordinary white and Lan Se plastics or foam banana bagging are similar to, and has effects such as better gas permeability, insect protected, sunshade than plastics or foam.
4, the banana bagging in degradation process and the residue after the degraded harmless or do not have potential hazard to natural environment, in natural environment, can all be degraded into fertilizer in 8 months;
5, through utilizing these discarded objects of banana stem stalk, effectively protected ecological environment.
