Description
(1) technical field
The present invention relates to a kind of using rice husk, high density polyethylene (HDPE) as the preparation side of the interface modification composite material of raw material
Method.Belong to the biomass-synthetic plastic research field using rice husk for backing material.
(2) background technique
Under sustainable development, environmentally protective historical background, reproducible biomass resource and ecological composite material
Become primary study object.The a part of forest and agricultural biomass as biomass energy, effectively exploitation and comprehensive utilization become
The new hot spot of energy research and environmental area.Currently, the utilization of forest and agricultural biomass is concentrated mainly on feed, Composting utilizes；
As Bio-Energy Material, by the methods of thermal transition, bioconversion, alcohol fuel, biology are converted by forest and agricultural biomass
The oxygenated fuels such as diesel oil are with substitute fossil fuels；Or by Timber residuals through high pressure compressed at scleroid bar-shaped or granule-shaped
Boiler oil molding, for family warm oneself；Furthermore the direct combustion gasification of raw material, is transformed into electric energy and is utilized.This
Outside, the preparation and development and utilization of charcoal, adsorbent can also be carried out by biomass carbonated technology, or extract agricultural residue
Useful component produces chemical products in object.
Wood plastic composite has started to widely apply as a kind of product of maturation, but the agricultural in addition to wood-fibred are remaining
Object construction material, in terms of application still in the elementary step.In numerous forest and agricultural biomass, rice husk resource is produced
Amount is abundant, cheap and easy to get, but its irrational utilization causes immense pressure to environment.Environmentally protective, sustainable development
Under it is required that, research and the utilization of rice husk are received significant attention.Therefore, this research is attempted to use forest and agricultural biomass rice husk and high density
Polyethylene is raw material, and to prepare environmental and ecological rice plastic composite materials of good performance, it prolongs as wood plastic composite
It stretches and develops, be expected to substitution traditional timber and be widely used in every field.
Quality of the plant fiber in conjunction with Study on Polymer Surfaces directly affects the performance of composite material.Due to wood fibre table
Face has a large amount of polar functional group, causes to be difficult to sufficiently merge between nonpolar high polymer.Therefore wood fibre is improved
With the interface binding power of polymeric matrix, improve two alternate interface compatibilities, becomes the key of wood plastic composite research
Content.The present invention, which mainly passes through, adds interface modification auxiliary agent during the preparation process to improve interfacial bond strength.
Based on the reality of China's Forest Resources scarcity, rice moulds the development of ecological composite material and application is the agricultures such as rice husk
The resource utilization of industry waste and waste plastic provides a new approach, to reduce timber resources consumption, alleviates China and builds
There is lack of raw materials that problem provides a possibility that very big for the industries such as material, packaging, is conducive to the protection of the forest reserves, and facilitate
It promotes resource to save and recycle comprehensively, there are preferable environment protection significance and economic results in society.
