Description
Technical field
The present invention relates to silicate plate technical field.More particularly, to a kind of fiber reinforcement for outdoor plank road
Silicate plate and its preparation method and application.
Background technology
As people occupies the continuous improvement with Leisure Environment, in cell or tourist attractions, increasing plank road is built, needed
Use substantial amounts of plank road plate.
Walk on the wooden footway in park, appreciate garden landscape, be the leisure way that many citizen like.Present wooden stack
Road and wood moulding plank road, the sheet material of use are mainly anticorrosive wood and wood moulding and a small amount of bamboo plank road, there are many inadequate natural endowments, such as
Service life is short, and is easily damaged by worms, perishable, does not prevent fires, and also largely to expend the forest reserves of preciousness, is unfavorable for that environment is protected
Shield.The good fiber silicates plank road plate of laying fire prevention, anti-corrosion, humidity resistance was both sturdy and durable, and environmental protection, also very beautiful
See.By factual survey, current plank road plate is mainly wooden plank road plate and wood plastics composite plank road plate and a small amount of bamboo plank road.
Wood and modeling essence are not suitable for open air and use, so generally, wooden footway plate is needed by preservative treatment, and just can guarantee that makes
With；As the wood moulding plank road plate of wood plastics composite product, it is also desirable to advanced complex technique, its outdoor applicable performance can just exceeded
Natural timber.Nonetheless, due to congenital, the useful life of wooden footway plate and wood moulding plank road plate is not long, general 5 years
Left and right need to do once big maintenance, and some low-quality products will even go wrong within 2 years.Data is introduced, only good fortune
State urban district, in recent years, every year to the maintenance cost of plank road more than 20,000,000 yuan.
Silicate material light weight board is due to its good resistance to weather, and anti-corrosion is mothproof, is well suited for open air and uses.Mesh
Preceding in the market does not see silicate plate for the report of outdoor plank road, need when fiber silicates plank road plate is used as plank road plate
Some technical problems are solved, is mainly manifested in：1) silicate light weight board is a kind of fragile material, and shock resistance is poor, when
Easily there is brittle failure in people, exist and use security risk, although this risk can be by the cooperation of system when jump is run on plank road
Reduce, but increased system cost；2) the apparent natural texture of silicate light weight board can not show a candle to wood based panel, much be chased after at present
To ask be difficult in the scape light plank road of natural quality high and received.
Using slurry flowing process or the silicate plate High anti bending strength for following the example of production is copied, but because it is sandwich structure,
Easily occurs interlayer structure destruction when the environment for having freeze thawing is used.
Therefore, the invention provides a kind of fiber reinforcement silicate plate for outdoor plank road, with compared with high impact-resistant
Property and there is the high-strength light sheet material of natural wood texture on surface, sheet material can be surveyed by strict outdoor use environment endurance quality
Examination, is adapted to the use of various plank roads.
The content of the invention
It is an object of the present invention to provide a kind of fiber reinforcement silicate plate for outdoor plank road.Traditional adopts
Plank road useful life with wooden plank road plate and wood plastics composite plank road plate is short, and silicate material has more preferable weather resistance, but
It is that silicate light weight board shock resistance is relatively low, brittle failure easily occurs.Fiber reinforcement silicate plate of the invention be have compared with
The high-strength light sheet material of high impact properties, can be tested by strict outdoor use environment endurance quality, be adapted to various plank roads
Use.Meanwhile, plate surface forms natural wood grain, and sheet material entire body color or surface color can also be tuned into the face of various timber
Color, the density of sheet material is with natural wood also substantially in a grade, and the plank road natural sense manufactured with it is fine.
It is another object of the present invention to provide a kind of preparation of the fiber reinforcement silicate plate for outdoor plank road
Method.The slab Coating combination that slurry flowing process and copying follows the example of production is poor, and sheet material frost resistance is poor, and the present invention is designed by formula, technique
Improve and equipment adjustment, realize the production with grained 20mm~40mm fiber reinforcements silicate plate, this sheet material has
Excellent physical and mechanical property, can use as outdoor plank road plate.
Third object of the present invention is to provide a kind of application of fiber reinforcement silicate plate for outdoor plank road.
To reach above-mentioned first purpose, the present invention uses following technical proposals：
