Description
Technical field
The present invention relates to chemical material field, particularly relate to a kind of rice husk Plant fiber's synthetic resin and preparation work thereof
Skill.
Background technology
China is as large agricultural country, and along with agricultural is scored consecutive bumper harvests, agricultural crop straw and other waste material yield the most significantly go up
Rising, wherein light straw yield is about 6.5 hundred million t/, and the process of wastes of crops straw etc. has become social problem, except few
Outside part is taken as feedstuff, fertilizer etc. to develop, major part is committed to the flames, not only wastes resource, and serious harm
Natural ecological environment, therefore, the comprehensive utilization of waste agronomic crop is significant.And the mankind are while creating modern civilization, also
It is negatively affected white pollution.Disposable tableware, Phthalates and agricultural mulching etc. are all difficult to recycling
Utilizing, its processing method is to burn and to bury.Burning can produce substantial amounts of harmful gas, pollutes environment；Bury wherein
The polymer short time in can not be decomposed by the microorganisms, also pollute environment.The residual plastic foil abandoned is present in soil, hinders farming
The growth of thing root system and to moisture, the absorption of nutrient, makes the gas permeability of soil reduce, causes crop production reduction；Action eats residual abandoning
Plastic foil after, intestinal obstruction can be caused and dead；The synthetic netting being lost in ocean or discard in ocean and fishline
Marine organisms are caused suitable harm, has therefore advocated green consumption imperative with reinforcement environmental conservation.In the face of day by day
Exhausted petroleum resources, popular biodegradation material is just becoming a research and development heat as high-tech product and environment-friendly products
Point.
Along with people are to resource, the raising of environmental consciousness, it has been recognized that resources conservation, environmental conservation are that the mankind can enter
The mandatory principle of row sustainable development, is the inevitable requirement of the Scientific Outlook on Development.Existing tableware on the market, furniture, kitchen tools
All use the products such as wood, bamboo, common plastics etc. the articles for daily use, this type of product cost is high, be unfavorable for degraded, not environmentally, Qi Zhongpu
Logical plastics not only can not be degraded, and is widely acknowledged as " white pollution ", destroys the water penetration of soil, and wood, Bamboo products to be cut down
Forest, has contaminated wastewater in manufacture process, be not good environment-friendly materials.It is subject to the filling-modified plastics of Plant fiber at present
The attention of countries in the world, this technology meets the theory of resources conservation, environmental conservation.Lignocellulosic fiber source is abundant, cheap, its
Density is less than all inorfils, and modulus and hot strength are close with inorfil, Plant fiber's potting resin materials processing
Time less energy consumption, the loss to process equipment is little, the beneficially saving of the energy in the course of processing, and can natural degradation, it is possible to subtract
That lacks plastics uses the pressure brought to environment, in a large number simultaneously for improving the production of people, life a kind of brand-new material of offer.
