Description
Technical field
The invention belongs to environment-friendly materials technical fields, and in particular to a kind of system of environment-friendly biomass composite flame-proof plate material
Preparation Method.
Background technology
China's agricultural straw resource is abundant, and national Primary Crop Straw in 2015 collects stock number and reaches 900,000,000 tons,
But China's agricultural crop straw comprehensive utilization ratio is relatively low, stalk surplus has caused crop straw burning, a series of society such as road safety
Meeting problem researches and develops agricultural crop straw high value comprehensive utilization technique by scientific and technical innovation, promotes the sustainable of China's agricultural production
Development, it has also become the whole society pays high attention to and hot issue urgently to be resolved hurrily.
The abundant stalk resource in China that develops into of artificial board of straw has found the new way rationally utilized, it is estimated that often giving birth to
1 cubic metre of agri-fiber based panel of production can consume 1.2 tons of agricultural crop straws, realize about 4 tons of carbon emission reduction.Develop agri-fiber based panel
It can not only solve the problems, such as agricultural crop straw waste treatment, preserve the ecological environment, and can be increased income with Huinong, promote peasant just
Industry.However, since agricultural crop straw is annual plant, fibre strength is well below timber, using agricultural crop straw as raw material system
Standby timber intensity is low, yielding, therefore a certain proportion of woody debris and crushed straw aggregate are mixed with wheat straw/timber homogeneous
Composite inorganic flakeboard is significant to improving plate property.
In recent years, as wooden class wood-based plate is fitted up indoors and the extensive use of Furniture manufacture process, by wooden decorative
The fire incident that material causes takes place frequently, and seriously threatens the security of the lives and property of people, and wooden class wood-based plate belongs to combustible material,
The a large amount of heat of combustion process release, rate of propagation are fast, moreover it is possible to discharge poison gas, therefore caused by fire hazard it is big.As building
It builds, finishing material, the fire protecting performance of plank is most important, and the flame retardant property assessment and detection to material are security against fire and design
Important content.Therefore, flame retardant property becomes an important finger of environment-friendly biomass composite flame-proof plate material popularization and application
Mark.
