Biodegradable material containing bamboo powder, and preparation method thereof

Abstract

The invention relates to the technical field of novel degradable materials, in particular to a biodegradable material containing bamboo powder, and a preparation method thereof. The biodegradable material comprises 15-30 parts of the bamboo powder, 2-6 parts of calcium carbonate and 40-65 parts of biodegradable resin, and coupling agents, biodegradable enzymes, phase solvents, photoinitiators, plasticizers, chain extenders, lubricants, active agents and the like are added to prepare the biodegradable material. The biodegradable material and the preparation method thereof have the advantages that the biodegradable material is made from the bamboo powder, the biodegradable resin, the coupling agents, the biodegradable enzymes, the plasticizers and the like, and the photoinitiators and auxiliary agents are added, so that the biodegradable material can have better mechanical properties and higher degradation rate than other existing plastic materials under the action of different factors in the natural environment; the biodegradable material is easy to prepare, wide in application range, sanitary and environmentally friendly.

Description

Technical field [0001] The present invention relates to the technical field of degradable new materials. Specifically, the present invention relates to a bamboo powder biodegradable material and a preparation method thereof. Background technique [0002] With the development of the country and the gradual improvement of the people's living standards, the people's health awareness and awareness of environmental protection have increased day by day. To create a comfortable, clean, antibacterial and mildew-proof living, learning and working environment that prevents the spread of diseases is what people are passionate about. The product waste can be automatically biodegraded and does not pollute the environment is also an urgent requirement of the current international environmental protection industry. [0003] At the beginning of the twentieth century, with the rapid development of the petroleum and chemical industries, plastics have been widely used in the production and life of h...

Problems solved by technology

[0003] At the beginning of the 20th century, with the rapid development of the petroleum industry and the chemical industry, plastics have been widely used in the production and life of human society due to their good thermal properties and chemical stability, which brought great impact to the production and life of human society. It has brought a lot of convenience, but it has also brought many negative impacts to human society, especially the disposable use of plastic products in human life (such as: agricultural mulch, lunch boxes, various packaging bags, beverage cups, shockproof materials, etc. ), which are discarded after completing their functions, and their recycling rate is very low. A large number of discarded plastic products can only be disposed of in simple ways such as landfill and incineration. After these waste plastic products are landfilled, they are It takes decades or hundreds of years to be partially degraded under natural conditions, thus causing serious pollution and damage to the natural environment and ecological environment, and seriously affecting the living conditions of future generations; if these waste plastic products are incinerated, they will release Harmful gases also cause serious pollution and damage to the natural environment and ecological environment, causing air pollution and affecting people's daily life.

[0005] Although degradable materials have been developed at present, the production process of the degradable materials produced by the existing technology is complicated, the processing is difficult, the use cost is high, and it cannot be widely used. In addition, the existing degradable materials are being discarded to nature. After the environment, the degradation rate is slow, and it takes more than 10 years to be naturally degraded. After degradation, there will still be some residues that cannot be decomposed and degraded by nature, which cannot be completely degraded.

[0006] Patent No. ZL200410061464.X's Chinese invention patent "bamboo fiber, bamboo powder, wood fiber resin-based composite material" (authorized announcement number is CN1284831C) discloses a kind of bamboo fiber, bamboo powder, wood fiber resin base as the main raw material Composite materials, adding additives such as adhesives, curing agents and diluents, are complicated to prepare, and need to be pressed and molded under specific temperature and pressure conditions. The finished product has a rough appearance, poor cuttability and difficult processing. Injection blow molding The molding effect is not ideal, the manufacturing cost is high, and the degradability rate is low
