Abstract
The utility model discloses a bamboo fiber cement composite board, which comprises a cement substrate. Bamboo fibers are uniformly filled into the cement substrate, and have the average length of 1 to 4mm. As the bamboo fibers are filled into the cement substrate, the composite board of the utility model has high impact resistance and strong breaking strength, and can be applied in the application field of outer walls and the like; and as the main fibers are nontoxic and harmless per se, the composite board is nontoxic.
Description
Technical field
The utility model relates to a kind of cement plate, relates in particular to a kind of bamboo pulp fiber cement plate.
Background technology
The fibrous magnesium silicate cement plate is traditional fiber cement board, has good physical and mechanical property and good weather resistance, is used for the peripheral structure and the water-proof material of buildings in a large number.Find that in recent ten years asbestos have damaging effect to HUMAN HEALTH.
The utility model content
The purpose of this utility model provides a kind of toxicological harmless and sound construction, shock resistance is strong, folding strength is high, can be applicable to the bamboo fibers cement composite board of Application Areass such as exterior wall.
For achieving the above object, a kind of bamboo fibers cement composite board of the present utility model comprises: cement matrix, in this cement matrix, evenly be filled with bamboo fibers, and the mean length of this bamboo fibers is 1～4mm.
Preferably, the mean length of described bamboo fibers is 2～3mm.
The utility model is by compound bamboo fibers in cement matrix, make not only that the shock resistance of composite sheet is strong, folding strength is high, can be applicable to Application Areas such as exterior wall, and principal fiber itself is nontoxic, so compound sheet material do not have toxicity yet.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the composite plate structure synoptic diagram of hollow structure.
Embodiment
As shown in Figure 1, the utility model comprises: cement matrix 1, in cement matrix 1, evenly be filled with bamboo fibers 2, and the mean length of bamboo fibers 2 is 1～4mm, the mean length of bamboo fibers is preferably 2～3mm.The utility model both can have been made the bamboo fibers cement composite board as the solid construction of Fig. 1, also can make the composition board as the hollow structure with square hole 3 of Fig. 2, and among Fig. 2, square hole 3 length and widths are 1.5cm, and spacing is 2cm.
The utility model can prepare by following 2 kinds of methods, and a kind of is wet process forming method, and another kind is the semi-dry pressing method.
The bamboo fibers cement plate of wet moulding; main component is mixed by sulfate bamboo pulp fiber, cement and levigate quartz sand; wherein; cement had both been made matrix in sheet material, play adhesive effect again, and it is whole with the bonding one-tenth of dispersive fiber; and protection fiber reinforcement; the quartz sand low price with quartz sand instead of part cement, makes that this plate is cheap.The proportioning raw materials of wet process forming method: (1) sulfate bamboo pulp fibre content (%) is 8 (accounting for gross weight); (2) cement/quartz sand is 1.5; (3) toughener polypropylene fibre content (%) is 0.2.By vapor cure 8h under high pressure 5～30MPa and 160 ℃ of conditions of high temperature.Its technical indicator is density (g/cm
3) be 1.55～1.7, folding strength (MPa) is 14.61, and 24h thickness swelling (%) is 0.3, and water-intake rate (%) is 13.5, the level that is higher than fiber reinforcement low alkalinity cement building slab (JC/T626-2008) acceptable end product also is higher than the prescribed value of Japanese Side fascia standard JIS A 5422.
The bamboo fibers cement plate of semi-dry pressing, main component is mixed by sulfate bamboo pulp fiber, cement and levigate quartz sand.The proportioning raw materials of semi-dry pressing: (1) sulfate bamboo pulp fibre content (%) is 5; (2) fiber/water mud is 0.14; (3) water cement ratio is 0.3; (4) toughener polypropylene fibre content (%) is 0.2; (5) thickening material Vltra tears (HPMC) content (%) is 0.2.By vapor cure 8h under high pressure 5～30MPa and 160 ℃ of conditions of high temperature.Its technical indicator is density (g/cm
3) be 1.56～1.60, folding strength (MPa) is 8.76, and 24h thickness swelling (%) is 0.04, and water-intake rate (%) is 17.6, satisfies the level of fiber reinforcement low alkalinity cement building slab (JC/T626-2008) acceptable end product.The bamboo pulp fiber cement sheet material sound construction of wet moulding and semi-dry pressing, shock resistance is strong, folding strength is high, can become good Side fascia material, and its specification is the wide 400～600mm thickness of long 1200mm～2000mm 12～20mm.
Have sound construction, shock resistance is strong, folding strength is high performance by the prepared the utility model bamboo fibers cement composite board of aforesaid method, can be applicable to Application Areass such as exterior wall, wherein hollow plate density is light, is convenient to transportation.
Claims (2)
1. a bamboo fibers cement composite board is characterized in that, comprising: cement matrix, in this cement matrix, evenly be filled with bamboo fibers, and the mean length of this bamboo fibers is 1～4mm.
2. bamboo fibers cement composite board as claimed in claim 1 is characterized in that, the mean length of described bamboo fibers is 2～3mm.
