Abstract
The present invention provides a straw fiber cement composite material which belongs to the field of building material. The present invention has the main characteristics that various sectional bars are prepared from raw materials of the following proportion by weight: 1 to 75 of straw fiber, 10 to 95 of cement and a right amount of mildew inhibitors, water reducing agents, waterproof agents, reinforcing agents, etc. by mixing with water, pressing and forming. The present invention is suitable for producing dalle, woodworker plates, fire-proof plates (do not need additional processing), suspended ceiling materials, heat insulating plates, light-duty walls, floors (can be used for site construction), ventilating pipes, mould plates (can be used only once and do not need demoulding), packaging boxboards, etc. The present invention has the obvious advantages of convenient application, no environment pollution, flame resistance, endurance, water resistance, corrosion resistance, decorativeness increase, etc., has good social and economic benefits, can replace and save wood, and add the value of the discard straw.
Description
Technical field
The invention belongs to building material technical field, relate to a kind of straw fiber cement composite material.
Background technology
Stalk is as the annual crops by-product, and resource is quite abundant, and because of its volume is big, the combustion value is low, and utilization ratio is extremely low, is abandoned field or on-site incineration in a large number, and security incident takes place serious environment pollution.
Someone attempts to utilize wheat straw stalk and fiber thereof to make sheet material.Existing wheat straw fiber density board adopts trimeric cyanamide or organic binder bonds such as resol, urea-formaldehyde resin as tackiness agent, has existed a large amount of formaldehyde and has discharged pollution and toxic hazard surrounding environment, major defects such as intensity and poor water resistance; Existing wheat straw stalk cement density plate is because the surperficial wax of wheat straw stalk has influenced its intensity and use range.In a word, owing to the defective of prior art, restricted the sustainable utilization of a large amount of stalks.
Summary of the invention
Of the present invention be to develop a kind ofly can overcome the defective that prior art is utilized stalk than the material of construction of good utilisation crop material, a large amount of depleted crop materials are rationally utilized, save a large amount of wooden boards or other material of construction.
The technical solution used in the present invention adopts following weight percent raw material: stalk fibre 1-75%, cement 10-95%, mould inhibitor 0-5%, water reducer 0-1%, water-resisting agent 0-5%, toughener 0-30%.
And adopt following technical process: stalk is disconnected becomes unwoven or untiwisted------removes wax and----mixes with cement, each additive, suitable quantity of water that--------------is processed into section bar in maintenance in extrusion forming.
In described raw material, wherein said stalk refers to agricultural crop straw and other non-forest tree stalks such as wheat straw, straw; Mould inhibitor refers to zinc sulfate or zinc oxide, borax, Tegosept E, mould inhibitor commonly used such as pentachlorophenol; Water reducer refers to sulfonated lignin, or naphthalenesulfonate, water reducers such as silicone oil; Water-resisting agent refers to paraffin, grease, water-resisting agents such as pitch; Toughener refers to silicon-dioxide, or lime carbonate, magnesium chloride, calcium oxide, calcium sulfate, packing materials such as aluminum oxide.
This straw fiber cement composite material of the present invention can be set different proportionings according to different purposes, the dalle of producing, and carpenter's sheet material weathering resistance, water tolerance, rotproofness improves, and the toxicological harmless material discharges; The PLASTIC LAMINATED of making does not need other special processing, and can not burn can be not combustion-supporting; The ceiling material moisture resistivity of making, good endurance, pollution-free; The heat insulating sheet material of making, light wall, good corrosion resistance, energy consumption is low, and maintenance cost is low; The template of making can the disposable not demoulding of use, does not repair, and saves man-hour; Manufacture of Floor, but site operation, good endurance; Make ventilator trunk, nonpoisonous and tasteless, atmosphere pollution not; Also can make tr, water-repellancy, solidity to corrosion is good.
This straw fiber cement composite material of the present invention is owing to fiber and the cement inorganic adhesive with the agricultural crop straw made is main raw material; so do not need to consume timber; protect and saved the forest reserves; make discarded stalk obtain utilizing increment; in use; use conveniently and save man-hour; use the back unharmful substance to discharge, free from environmental pollution, and also it is not combustion-supporting not burn; security; weather resistance, weathering resistance, erosion resistance; ornamental raising has tangible advantage and favorable social and economic benefits.
Embodiment
The embodiment 1 of straw fiber cement composite material of the present invention adopts following weight percent raw material: stalk fibre 75%, cement 10%, mould inhibitor 2%, water reducer 1%, water-resisting agent 2%, toughener 10%.
The embodiment 2 of straw fiber cement composite material of the present invention adopts following weight percent raw material: stalk fibre 1%, cement 95%, mould inhibitor 1%, water reducer 1%, water-resisting agent 1%, toughener 1%.
The embodiment 3 of straw fiber cement composite material of the present invention adopts following weight percent raw material: stalk fibre 30%, cement 50%, mould inhibitor 2%, water reducer 0.5%, water-resisting agent 3%, toughener 14.5%.
In described technical process, when making section bar disconnected broken the beating of stalk become unwoven or untiwisted, the paraffin removal technology is removed the wax in the stalk in the traditional paper technology of reference, makes stalk fibre, need adjust the setting proportioning according to different purposes, described raw material is evenly mixed with suitable quantity of water in proportion, adding is suitably pressurizeed moulding according in the mould that purposes made to the die face plate, with reference to concrete curing method maintenance for some time, and rebuild and promptly made straw fiber cement composite material of the present invention after the demoulding.
