Embodiment 1

[0060] A corncob cellulose foaming material, the raw material components of the corncob cellulose foaming material include: a solution of corncob cellulose and reinforcing cellulose, a foaming agent and a pore-forming agent;

[0061] The total mass percentage of corncob cellulose and reinforcing cellulose in the solution of the corncob cellulose and reinforcing cellulose is 7%; the quality of the reinforcing cellulose is 50% of the corncob cellulose mass; the The quality of whipping agent is 4% of the solution quality of corncob cellulose and reinforced cellulose; The quality of described pore forming agent is 3 times of the solution quality of corncob cellulose and reinforced cellulose;

[0062] The reinforcing cellulose is selected from absorbent cotton;

[0063] The whipping agent is selected from p-toluenesulfonyl hydrazide;

[0064] The pore forming agent is selected from sodium sulfate.

[0065] A kind of preparation method of above-mentioned corncob cellulose foaming ...

Embodiment 2

[0072] Compared with Example 1, the only difference is that the foaming agent p-toluenesulfonylhydrazide in Example 1 is replaced by diethyl azodicarboxylate, and other conditions remain unchanged.

Embodiment 3

[0074] Compared with Example 1, the only difference is that the reinforced fiber absorbent cotton in Example 1 is replaced by flax, and other conditions remain unchanged.

Abstract

The invention provides a corncob cellulose foaming material as well as a preparation method and application of the corncob cellulose foaming material. The corncob cellulose foaming material comprises the following raw materials which are taken as components: a corncob cellulose and enhanced cellulose solution, a foaming agent and a pore-forming agent. The preparation method of the corncob cellulose foaming material comprises the following steps: (1) mixing the foaming agent and the pore-forming agent in a formula ratio with the corncob cellulose and enhanced cellulose solution to obtain a mixture; (2) injecting the mixture into a mould to be foamed and molded, so as to obtain a molding material; (3) washing the molding material and drying to obtain the corncob cellulose foaming material. The corncob cellulose foaming material has the functions of buffering, shock absorption, heat preservation, filtration and the like and has outstanding elasticity, and can be widely used in industries of furniture, automobiles, packaging and the like; furthermore, the corncob cellulose foaming material is non-toxic and degradable, and has no toxicity to soil or air, and further is simple in preparation method, capable of being used in a large scale and favorable to rural economic development.

Description

technical field [0001] The invention belongs to the technical field of foaming materials, and relates to a corn cob cellulose foaming material and a preparation method and application thereof. Background technique [0002] The main component of the filling materials used in sofa furniture, pillows, cushions, etc. on the market is polyurethane. However, polyurethane foam is flammable. Once burned, it will produce a gas containing highly toxic hydrogen cyanide. If a person inhales it, he will be poisoned and die. When polyurethane products exceed the service life, their performance will be greatly reduced and they will be scrapped. These waste materials must be recycled, which will increase the cost and cause certain pollution to the environment. [0003] As the most abundant and renewable biomass resource on the earth, cellulose has the advantages of good biocompatibility, easy degradation, and easy derivatization, and will become one of the main raw materials for chemical p...
