Description
Technical field
The present invention relates to a kind of wooden refinforced cement moulding plate and production technique thereof, belong to the environment-friendly building materials field.
Background technology
At present, cement-bonded wood chipboard has been widely used as inside and outside wall board, partition plate, floor, ceiling board, roof boarding etc. as the alternate material of timber, this sheet material generally is that the material preparation with cement, wooden shavings and flyash forms, and it has, and intensity is higher, water tolerance and resistivity against fire, heat insulation property characteristics preferably.But, also existing such as easily buckling deformation at normal temperatures, shrinking percentage is big; Easily broken, workability is poor, can not follow closely, digs, reprocessing such as saw; Flyash mixed little with ratio, the specific surface area of flyash is little, causes aquation insufficient, and the density of sheet material is reduced, and intensity reduces; The outward appearance dullness, pattern is simple, can ornamental difference and when producing labor condition poor, work usefulness is low, defectives such as level of automation difference.
Summary of the invention
The technical problem to be solved in the present invention is exactly the problems referred to above that existing cement-bonded wood chipboard exists, for the people provide a kind of lightweight, high-strength, fire prevention, waterproof, anti-ly damage by worms, use attractive in appearance; Can saw, can follow closely, can dig wooden efficiently refinforced cement moulding plate of simple installation and production technique thereof.
The present invention is prepared from following ratio by following starting material:
Wood wool: 10-35%
Cement: 30-50%
Flyash: 15-50%
Water glass: 0.1-15%
Water: 1-10%
Also waterproof dose 0-3% in the said mixture material can add according to different requirements and ratio.Described wood wool is given birth to economic tree for speed and is prepared from, and the size of wood wool is long 20-100 millimeter * wide 1-10 millimeter * thick 0.1-1 millimeter.
In the above-mentioned starting material, flyash specific surface area should be at 3000-6000m
2Between/the g, the size of wood wool is: long 20-100 millimeter, wide: 1-10 millimeter, thick: 0.1-1 millimeter.
Production technique of the present invention comprises the steps:
1) wood wool, cement, flyash, water glass, water are mixed in proportion stir into mixture through mating formation into slab, slab compression molding in transportation;
2) slab of moulding is sent into the curing kilns temperature at 60-95 ℃, humidity at 60-100%, maintained 6-12 hour, advance again steam-cured still through 1-3 the steam-cured 7-16 of normal atmosphere hour, after naturally cooling.
3) cooled sheet material carries out drying under 88-100 ℃ temperature;
4) dried sheet material is cut by required specification;
5) the utilization spraying coating process uniformly sprays water-borne coatings and paint at plate surface.
In the above-mentioned production technique, the pressure of pressing machine is the 1200-3000 ton in the step 1), sheet material water ratio after drying should be 6-12% in the step 3), and color can spray according to customer requirements in the step 5), and becoming specification baseboard material is long 900-3000mm * wide 600-1200mm * thick 6mm-50mm.
The present invention has following advantage:
1, select the brush wood of the living economy of speed for use, raw material sources are abundant, and cost is lower;
2, vast scale adds industrial waste flyash, and the further hydration enhancement of applying powder coal ash has reduced sheet material shrinking percentage at normal temperatures, has further improved the intensity of sheet material;
3, adopt the high-pressure steaming and cultivating maintenance technology, improved the performance index of product;
4, adopt die press technology for forming, can make product have the sheet material of multiple outer shape, pattern;
5, can give product different decorative effects by colored coating process, make product have extremely strong personal characteristics, improved the aesthetic of sheet material and adopted the PLC production control system, improved labour productivity, reduced personnel's labour intensity in whole production line.
After testing, 1000 hours no changes of 48 hours no changes of 96 hours no changes of the surperficial water tolerance of wooden refinforced cement moulding plate of the present invention, surperficial alkaline-resisting life, surperficial abrasion resistance 〉=5000 time, surperficial artificial ageing resistance, surface hardness＞2h.Therefore, this sheet material goes among can being widely used in the utilization of public and covil construction, decoration and other aspect, can replace other building and finishing material.
