Problems solved by technology

[0002] As a kind of daily necessities and industrial products, foamed plastics have appeared for decades and become an indispensable item in industrial production and people's life. The foamed products sold in the market are mainly polyurethane and polyester derived from petroleum products. It is made of styrene, which not only pollutes the environment during the production process, but also is difficult to degrade the waste, especially when it is used for human hygiene, household washing and makeup, long-term use will cause certain harm to people

Embodiment 1

[0029] Embodiment 1, the present invention provides a kind of ecological environment-friendly material, comprises cellulose raw material, reinforcing fiber, NAOH solution, sulfuric acid, pore-forming agent and auxiliary agent, and described cellulose raw material is from plant stem, bar and shell Extracted pure cellulose, the reinforcing fiber is one of cotton, flax and pineapple hemp, and the auxiliary agent includes a debonding agent, a plasticizer and a stabilizer.

[0030] Further, the plasticizer is ethylene glycol and ethanolamine, the stabilizer is an antifungal agent and a light stabilizer, and the debonding agent is a quaternary ammonium salt containing more than 18 C atoms.

[0031] Further, the pore forming agent is sodium sulfate.

[0032] Further, the length of the reinforcing fiber is 8-20mm.

Embodiment 2

[0033] Embodiment two, such as figure 1 As shown, the invention provides a kind of preparation method of eco-type environment-friendly material, comprises the following steps:

[0034] S1010, solution preparation includes: 1, the configuration of NAOH solution: configuration concentration is 10wt%-15wt%

[0035] 2, the configuration of cellulose solvent: take a certain amount of NAOH and sulfuric acid,

[0036] Put it into quantitative distilled water, and configure mixed solutions with concentrations of 9wt% and 7wt% respectively;

[0037] S103, pretreatment of cellulose: cut the cellulose into cubes with a length and width of about 2 cm, weigh 10 g of cellulose raw material, put it into NAOH solution, soak it for 2 hours, take it out and air-dry it naturally, put the air-dried cellulose into clean water and soak it After a period of time, wash until weakly alkaline, and dry for later use;

[0038] S105, dissolving cellulose: put the dried alkali cellulose into a solvent, ...

Abstract

The invention belongs to the field of preparation of environmentally-friendly materials, and especially relates to an ecological and environmentally-friendly material. The material comprises a cellulose raw material, reinforcing fibers, a NaOH solution, sulfuric acid, a pore-forming agent and auxiliary agents, the cellulose raw material is pure cellulose extracted from stems, stalks and shells ofplants, the reinforcing fibers are one of cotton, flax and pineapple hemp, and the auxiliary agents comprise a debonding agent, a plasticizer and a stabilizer. The cellulose belongs to renewable resources, so that the consumption of natural energy is reduced; and the cellulose is a biodegradable high-molecular compound, has excellent performances in use, and can be quickly decomposed into low-molecular compounds under the action of microorganisms after being discarded, so that the sponge taking the cellulose as the raw material is beneficial to environmental protection of human beings.

Description

technical field [0001] The invention belongs to the field of preparation of environment-friendly materials, and in particular relates to an ecological environment-friendly material and a preparation method thereof. Background technique [0002] As a kind of daily necessities and industrial products, foamed plastics have appeared for decades and become an indispensable item in industrial production and people's life. The foamed products sold in the market are mainly polyurethane and polyester derived from petroleum products. It is made of styrene, which not only pollutes the environment during the production process, but also is difficult to degrade the waste, especially when it is used for human hygiene, household washing and makeup, long-term use will cause certain harm to people. With the continuous reduction of petroleum resources, the source of its raw materials will also be a serious problem. After entering the 21st century, people have a better understanding of environ...
