Abstract
The invention relates to a composite board, in particular to a cement straw composite board, and belongs to the technical field of building material processing. The composite board is prepared by taking portland cement, fly ash, wood shavings or straws as main materials and other auxiliary agents as auxiliary materials, paving the raw materials into a board blank after stirring, and drying the board blank after hot pressing, indoor curing and steam curing in a steam curing kettle. The cement straw composite board can be widely used as ceiling boards, non-bearing internal partition boards, floor boards, roof boards and external wall boards of various buildings.
Description
Technical field
The present invention relates to a kind of composition board, be specifically related to a kind of cement straw composition board, belong to the material of construction processing technique field.
Background technology
At present, along with socioeconomic fast development, the various places construction industry is surging forward; Drive the material of construction demand and roll up, and cementitious composite sheet material has good physical and mechanical property, waterproof fireproofing performance, is a kind of novel wall material and decorating and renovating material of high comprehensive performance; But the production and processing technology of cement composite board is relatively backward; Yield poorly down, desired raw material is single, and finished product output, quality all can't be met the need of market.
Summary of the invention
The objective of the invention is for overcoming the weak point of above-mentioned prior art; A kind of cement straw composition board is provided; This composition board is a main raw with silicate cement, flyash, wood particle or stalk; Be equipped with other auxiliary agent, mat formation into slab after the raw material stirring, carry out steam-cured after drying through hot pressing, indoor maintenance, steam-cured still again and get finished product.The cement straw composition board can be widely used as various buildingss ceiling ceiling board, non-bearing inner partition plate, panel, roof boarding, Side fascia.
The present invention realizes with following technical scheme: a kind of cement straw composition board is characterized in that: it is a main raw with silicate cement, flyash, wood particle or stalk, is equipped with other auxiliary agent; Its proportioning comprises following weight part: 30～40 parts of stalk or wood wools; 18～30 parts in flyash, 20～50 parts of cement, 1～3 part of water glass; Quicklime 0.3-1.8 part, 0.1～2 part of auxiliary agent.
Described auxiliary agent is one or more in sodium-chlor, plaster stone, calcium hydroxide, the sodium sulfate.
A kind of method for preparing the described cement straw composition board of claim 1; It is characterized in that: (1), stalk or wood wool, flyash, cement, water glass, calcium chloride, water and auxiliary agent are mixed, stir, mat formation into slab then; To the pressurization of slab buttress, pressure is 3.5-4.5MPa; (2), send into indoor maintenance to slab buttress, room temp is 70 ℃-90 ℃, curing time 8-12 hour; (3), to send the sheet material of maintenance steam-cured still to carry out steam-cured, pressure is 1.8-4MPa, the time is 8-16 hour, cooling is carried out drying to sheet material then, drying temperature is 60 ℃-75 ℃, makes water ratio reach 5%-10%.
Advantage of the present invention is: this composition board is a main raw with silicate cement, flyash, wood particle or stalk, is equipped with other auxiliary agent, mats formation into slab after the raw material stirring, carries out steam-cured after drying through hot pressing, indoor maintenance, steam-cured still again and gets finished product.Cement-bonded wood chipboard can be widely used as various buildingss ceiling ceiling board, non-bearing inner partition plate, panel, roof boarding, Side fascia, have that intensity height, fire protection flame retarding property are good, water tolerance and good characteristics of sound-insulating performance.
Embodiment
Below in conjunction with embodiment the present invention is done further explain:
