Description
Technical field
The present invention relates to chemical material field, particularly relate to a kind of chestnut shell Plant fiber's synthetic resin and preparation technology thereof.
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 rise, 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 small part is worked as
Make outside feedstuff, fertilizer etc. develops, major part is committed to the flames, not only wastes resource, and serious harm natural, ecological ring
Border, 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 be recycled, its process side
Method is to burn and to bury.Burning can produce substantial amounts of harmful gas, pollutes environment；Bury the polymer short time the most therein
In can not be decomposed by the microorganisms, also pollute environment.The residual plastic foil abandoned is present in soil, hinder crops root system growth and
To moisture, the absorption of nutrient, make the gas permeability of soil reduce, cause crop production reduction；After action eats the residual plastic foil abandoned, meeting
Cause intestinal obstruction and dead；Marine organisms are caused by synthetic netting and fishline that be lost in ocean or discard in ocean
Suitable harm, therefore advocates green consumption imperative with reinforcement environmental conservation.In the face of day by day exhausted petroleum resources, symbol
In the swim biodegradation material is just becoming a research and development focus as high-tech product and environment-friendly products.
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 carry out can
The mandatory principle of sustainable development, is the inevitable requirement of the Scientific Outlook on Development.Existing tableware on the market, furniture, kitchen tools etc. are raw
Product of applying flexibly all use the products such as wood, bamboo, common plastics, and this type of product cost is high, be unfavorable for degraded, not environmentally, the most commonly
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 gloomy
Woods, has contaminated wastewater in manufacture process, be not good environment-friendly materials.At present with the filling-modified plastics of Plant fiber by generation
The attention of various countries of boundary, 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, during Plant fiber's potting resin materials processing
Less energy consumption, the loss to process equipment is little, the beneficially saving of the energy in the course of processing, and energy natural degradation, it is possible to reduce
Plastics use the pressure brought to environment in a large number, simultaneously for improving the production of people, life provides a kind of brand-new material.
