Description
Technical field
The invention belongs to construction material fire-proof and damp-proof technical field, more particularly to a kind of fire-proof and damp-proof wheat（Rice）Stalk board.
Background technology
China is world's fiberboard（Or particieboard）The big country of production and consumption first, and turn into fiberboard in the world（Or
Particieboard）Fastest-rising country and big export country.Fiberboard also known as density board, traditional fiberboard be with wood fibre or its
His plant cellulose fiber is raw material, applies wood-based plate made of Lauxite or other applicable organic adhesion agents, particieboard is by wood
Particle made of material or other ligno-cellulosic materials, apply adhesive after heating power and pressure effect under compose it is artificial
Plate, also known as flakeboard.
Fiberboard（Or particieboard）As the favorable substitutes of timber, be widely used in furniture, timber floor, building, decoration,
The industries such as shipbuilding, vehicle, it is more excellent compared to other like product qualities, performance.Under the background of forest tree resource shortage, fiber
Plate（Or particieboard）Market demand constantly rise.But the fiberboard as produced in conventional processes has the side such as fire prevention, waterproof
The shortcomings that face, restricts, and is especially the maximum of fiberboard application with the not environmentally property of the fiberboard of the adhesive producings such as Lauxite
Obstacle.
Due to the generation of a lot of building heat preservation event of fire in recent years, the thinking of each bound pair insulated fire is triggered, has been incubated
The unprecedented great attention for causing all circles in the industry of the fire protecting performance of material.However, many insulation materials it is on fire be all
Caused by work progress, such as：Electric welding, naked light, bad construction custom.These materials are constantly caused in combustion to be melted
Thing and toxic smoke are dripped, while the CFC that discharges, hydrofluorocarbons, the harm of the gas to environment such as freon can not also neglect
Depending on.Issued therefore, house and town and country construction portion and the Ministry of Public Security combine《Civil buildings outer heat preservation system and decoration of exterior wall fire prevention are temporary
Professional etiquette is determined》Notice, carries out fireproof heated board energetically.Existing fireproof heated board, has the disadvantage that：Fault in material causes to prevent fires
Heat insulation effect is poor, and no facing is so that sheet material unsightly, using particieboard cost height and destroys ecological environment, just because of above-mentioned original
Cause, fireproof heated board fail commercially to mention good popularization always.
At present without the forest for mankind's exploitation, the preciousness that trees will become.And trees are the substantially former of timber
Material, and the needs that the mankind build.If the technology of artificial stalk board, that can saves many trees, and stalk is most
Common thing.Annual China can produces 700,000,000 tons of stalk, according to incompletely statistics, stalk being utilized in the world etc.
For agriculture and forestry organic waste material less than 2%, the utilization rate of the current stalk in China is 33%.
Straw plate plate is to utilize a kind of artificial composite board of function admirable made of agricultural production residue-stalk.It is
A kind of homogeneous sheet material as medium-density plate, and the surface with unusual light；Its formaldehydeless release, thus do not pollute ring
Border.It is not against the wood raw material of worsening shortages, and it is raw material to use annual all renewable cheap and inexhaustible wheat straw,
Gu and can meet building and furniture industry to it is growing the needs of.With promoting the use of for straw plate plate, market is to its performance
It is required that also increasingly improve.The shortcomings that it is prevented fires, heat-resisting and moisture protection is one fatal as nonmetallic materials；Therefore, how
The fire protection flame retarding and moisture protection for solving the problems, such as straw plate plate have become particularly important, and rational preparation technology can effectively change
It is apt to this problem.
