Description

Fungus damage-prevention and anti-collision packaging material and production method thereof

Technical Field

Background

At present, the packaging materials of commercial products on the market are mainly petroleum-based composite materials such as Expanded Polystyrene (EPS) and the like, and the materials are widely used in the field of packaging due to the characteristics of light weight, low moisture absorption rate, excellent buffering performance, low price and the like. However, because the polystyrene material has stable chemical properties, the polystyrene material is not degraded after being discarded in natural environment within 200 years, thereby causing serious white pollution to the society, recycling the polystyrene material and consuming more cost. Therefore, it is imperative to find an environment-friendly packaging material. In recent years, the development of new fiber cushioning packaging by utilizing crop resources has become a new research direction.

The heat insulation, decoration and durability of the straw wallboard are superior, and the straw board is widely applied to the building industry as a substitute of wood boards and ceramic tiles in many developed countries. In addition, the straw processed by the technical method can also be used for manufacturing rayon and cotton, producing furfural, maltose, wine and xylitol, processing fiber boards and the like. At present, most of straw treatment methods are direct incineration, so that resources are wasted, and gas generated by straw combustion is greatly harmful to the atmosphere.

In order to improve the utilization rate of the straw, the prior art utilizes developed fungal mycelia and strong mycelia kinking capability, so that specific fungi with high conversion capability of cellulose and lignin can be screened, biomasses such as straw leaves and the like are decomposed and glued to develop a novel environment-friendly biomass material, and the novel biomass material replaces foamed plastic used for daily packaging.

finally, continuously stirring for 5-10 min, standing and fermenting for 30-60 min.

In the ratio process of biological stickness batching, the stirring of soluble starch, sucrose and lime powder forms the pasty material that has the stickness, and hot water promotes the decomposition of sodium bicarbonate powder, consequently at the in-process of fermentation, will produce the bubble in the biological stickness batching to increase the fluffy sense improvement stickness of biological stickness batching.

Lime powder also will take place chemical reaction when meeting water in addition to release the heat simultaneously, the heat that produces this moment will make sodium bicarbonate decompose completely at the in-process of biological stickness batching stirring fermentation, consequently further improves the stickness of biological stickness batching, and cane sugar and soluble starch also are fit for growing with the adhering to of fungus silk in addition, and consequently the cross adhesion of matching of biological stickness batching and fungus silk will improve overall material's stability.

200, performing primary fungus seedling culture, namely diluting and mixing the fungus breeding into the sterilized wheat bran and corncob powder, adding the diluted wheat bran and corncob powder into the cottonseed hulls in batches, adding water, uniformly stirring to obtain a fungus culture raw material, and sealing and placing the fungus culture raw material in a dark room for culture until hypha covers the raw material.

In the step, the environment in the sealed darkroom can be adjusted to be the optimal growth condition for using the fungi, in addition, when water is added for uniform mixing, the water content of the fungi cultivation raw material is controlled to be about 65 percent, and the hypha covering raw material is not compacted when being sealed, so that the propagation and growth capacity of the hypha is improved.

It should be added that, because the temperature is not easily raised when the water is much and the fermentation is difficult when the water is little, the water content in the material can be judged by the following operations: the materials can be agglomerated by holding with hands, and the materials are preferably scattered when falling to the ground after being mixed with water by finger joints.

Step 300, extruding to form a fiber board and a straw board, uniformly stirring crushed multi-fiber grass leaves according to a ratio, adding biological viscous ingredients into the mixture, stirring and extruding to obtain the fiber board, uniformly stirring the cut toughness truncated straws according to the ratio, and inwardly adding the biological viscous ingredients, stirring and extruding to obtain the straw board.

The method comprises the steps that the multi-fiber grass blades and the toughness cut straws are respectively formed into independent material plates, different combined material plate interlayers can be formed according to production requirements according to the characteristics of the multi-fiber grass blades and the toughness cut straw raw materials, namely, the fiber plate-straw plate-fiber plate, the straw plate-fiber plate-straw plate or other superposition forms, so that the impact resistance performance can be improved, the application range can be further improved, and when the fungal filaments grow on the independent straw plates and the fiber plates, the individualized growth process can be realized according to different structures of fibers and straws, so that the adhesion capability of the independent straw plates and the fiber plates can be increased, and the structural stability is improved.

In step 300, the specific steps of extruding to form the fiber board are as follows:

adding a biological viscous material into the multi-fiber grass leaf material, stirring at a high speed, reducing the stirring speed after the multi-fiber grass leaf mixture gradually forms a sticky mass, adding a weak acid agent into the mixture, wherein the biological viscous material can adhere the multi-fiber grass leaf material into an integrated bulk structure, and the weak acid agent is organic acid in the process and cannot damage the environment;

after the mixture is continuously stirred until a large amount of bubbles are generated, the mixture is immediately sent into an extrusion device to be extruded into fiberboards with different thicknesses according to requirements, and the organic acid reacts with hydrated lime in the biological viscous material to generate the bubbles again, so that the inside of the fiberboards in the embodiment is filled with the bubbles, and the quality of the fiberboards is reduced.

The method for forming the straw board by extrusion comprises the following specific steps:

cut the toughness after the cutting and cut straw mixture and add water and soak until softening and detach unnecessary moisture, cut the biological stickness batching of straw mixture addition to the toughness after the softening to send into the straw board that extrudes into different thickness according to the demand in the extrusion device, toughness cuts the straw and easily stirs the adhesion with biological stickness batching, because the bubble that the sodium bicarbonate of biological stickness batching itself produced when decomposing, consequently straw inboard also has the bubble, has reduced the quality of fibreboard.

Fibreboard and straw board are when extrusion device extrudees, every face of fibreboard is equipped with a plurality of evenly distributed's interior heavy recess, the surface of straw board is equipped with a plurality of and the arc arch of interior heavy recess mutual interlock, and the mutual interlock of interior heavy recess and arc arch can multiplicable fibreboard and straw board the cohesion when the stack.
