Description
Technical field
The invention belongs to building material technical field, relate to a kind of cement-bonded wood chipboard and preparation method thereof specifically.
Background technology
Cement-bonded wood chipboard is used as the acoustic barrier material etc. of inside and outside wall board, partition plate, floor, railway or highway both sides abroad in a large number, and application at home at present is also progressively expanding.This sheet material is generally prepared from by cement, wooden shavings, flyash and various additive, and timber intensity is high, and fire protection flame retarding is good, water tolerance and sound-insulating performance all better.But in order to physical and mechanical properties such as the intensity that ensures cement-bonded wood chipboard, usually require that the calcium content of flyash is lower, general calcium oxide content is lower than 8%.
As Chinese patent CN200310106131.X discloses a kind of wooden refinforced cement moulding plate and production technique thereof, described sheet material is prepared from following ratio by following starting material: wood wool: 10-35%, cement: 30-50%, flyash: 15-50%, water glass: 0.1-5%, water: 1-10%.Its production technique comprises the following steps: 1) be mixed in proportion by each raw material and stir into mixture through mating formation into slab and compression molding; 2) slab is sent into curing kilns temperature 60-95 DEG C, humidity at 60-100%, maintenance 4-16 hour, then enters steam-cured still naturally cooling after 1-3 the steam-cured 6-12 of normal atmosphere hour; 3) cooled sheet material carries out drying at the temperature of 88-100 DEG C; 4) cuts sheet material; 5) plate surface is sprayed.Cost of the present invention is low, and timber intensity is high, and product can have multiple outer shape, pattern, improves labour productivity, reduces the labour intensity of personnel.
Disclosed in above-mentioned patent, wooden refinforced cement moulding plate does not relate to high-calcium fly ass and activator thereof.The calcium oxide content of the flyash wherein used is lower, according to during containing the high-calcium fly ass of more than 15% calcium oxide in this patent formulation, slab early strength may be caused lower, slab frangibility when unloading plate.High-calcium fly ass, because it contains more than 15% calcium oxide, the comparatively slow and volumetric expansion after aquation of its hydration rate, shrinking percentage is high at normal temperatures easily to cause sheet material, reduces the intensity of sheet material, has thus had a strong impact on the utilization of high-calcium fly ass in cement-bonded wood chipboard.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
High for light weight cement plate cost in prior art, the defects such as the production cycle is long, and operation is loaded down with trivial details, the object of the invention is to provide a kind of light weight, the environment protecting cement plate that with short production cycle, cost is low.
Technical scheme provided by the invention is:
A kind of cement-bonded wood chipboard, comprises following component: wood wool 10-40 part, high-calcium fly ass 15-50 part, aluminosulfate cement 30-55 part, water glass 2-5 part and calcium chloride 0.2-2.2 part by weight.

Preferably, the length of described wood wool is 10-30 millimeter.
As preferably, in described high-calcium fly ass, the content of calcium oxide is 15-40%; The mass percentage concentration of described water glass is 35%; The mass percentage concentration of described calcium chloride is 30%.
As preferably, described aluminosulfate cement is fast hard special cement, and after 3d, intensity can reach 42.5MPa.
The present invention also provides a kind of preparation method of cement-bonded wood chipboard, comprises the following steps:
(1) wood wool, high-calcium fly ass, aluminosulfate cement, water glass, calcium chloride, water and auxiliary agent are mixed, stir, then mat formation into slab, slab buttress fork truck is placed in chilling press, pressurizes.
(2), after the dwell time terminates, slab is carried out maintenance;
(3) sheet material being sent into steam-cured still carries out steam-cured, then cools;
(4) drying is carried out to sheet material, obtain described cement-bonded wood chipboard.
Wherein, step adds water when mixing raw material in (1), and the ratio controlling the gross weight of water and the weight sum of high-calcium fly ass and cement in mixture is 1:2.
Wherein, in step (1), when colding pressing to described slab, described pressure is 4-6MPa, and the dwell time is 4-8 hour.
Wherein, in step (2), control curing temperature is 30-40 DEG C, relative humidity 70-90%, curing time 8-12 hour;
Wherein, a steam-cured pressure 1.8-4 normal atmosphere of sheet material in step (3), steam-cured time 8-16 hour;
Wherein, the temperature controlling described drying in step (4) is 60-75 DEG C, makes the water ratio of sheet material reach 6-12%.
Compared with prior art, the present invention has following beneficial effect:
1. cement-bonded wood chipboard light weight of the present invention is high-strength, and low cost of manufacture is with short production cycle; Cement-bonded wood chipboard of the present invention adopts aluminosulfate cement to substitute prior art ordinary portland cement, substantially increases production efficiency.
2. cement-bonded wood chipboard of the present invention utilizes usually discarded high-calcium fly ass as tackiness agent, not only ensure that the use properties of cement-bonded wood chipboard meets " cement sawdust plate (JC/T411-1991) " standard-required, and greatly reduce the cost of cement-bonded wood chipboard.
