Description
Technical field
The present invention relates to silicate plate technical fields.More particularly, to a kind of fiber reinforcement for outdoor plank road
Silicate plate and its preparation method and application.
Background technique
With people occupy with the continuous improvement of Leisure Environment, in cell or tourist attractions, built more and more plank roads, needed
Use a large amount of plank road plate.
It walks on the wooden footway in park, appreciates garden landscape, be the favorite leisure way of many citizen.The present wooden stack
Road and wood moulding plank road, the plate of use are mainly anticorrosive wood and wood moulding and a small amount of bamboo plank road, and there are many inadequate natural endowments, such as
Service life is short, and vulnerable to damaging by worms, perishable, does not prevent fires, and also largely to expend the valuable forest reserves, is unfavorable for environment guarantor
Shield.The good fiber silicates plank road plate of laying fire prevention, anti-corrosion, humidity resistance was not only sturdy and durable but also environmentally protective, also very beautiful
It sees.By factual survey, current plank road is mainly wooden plank road plate and wood plastics composite plank road plate and a small amount of bamboo plank road with plate.
Wood and modeling essence are not suitable for outdoor use, so under normal circumstances, wooden footway plate is needed by preservative treatment, and just can guarantee makes
With；Wood moulding plank road plate as wood plastics composite product, it is also desirable to which advanced complex technique can just make its outdoor applicable performance be more than
Natural timber.Nonetheless, due to congenital, the service life of wooden footway plate and wood moulding plank road plate is not grown, and general 5 years
Left and right need to do primary big maintenance, and certain low-quality products will even go wrong within 2 years.Data introduction, only good fortune
State urban district, in recent years, every year to the maintenance cost of plank road at 20,000,000 yuan or more.
Silicate material light weight board is due to its good resistance to weather, and anti-corrosion is mothproof, is well suited for outdoor use.Mesh
The preceding report for not seeing silicate plate in the market for outdoor plank road, need when fiber silicates plank road plate is used as plank road plate
Solve some technical problems, be mainly manifested in: 1) silicate light weight board is a kind of fragile material, and shock resistance is poor, when
When running jump on plank road brittle failure easily occurs for people, exists using security risk, although this risk can pass through the cooperation of system
It reduces, but increases system cost；2) the apparent natural texture of silicate light weight board can not show a candle to wood based panel, much chase after at present
It asks and is difficult to be received in the scape light plank road of high natural quality.
The silicate plate High anti bending strength of production is followed the example of using slurry flowing process or copy, but since it is sandwich structure,
The environment for having freeze thawing using when easily there is interlayer structure destruction.
Therefore, the present invention provides a kind of fiber reinforcement silicate plates for outdoor plank road, have compared with high impact-resistant
There is the high-strength light plate of natural wood texture on property and surface, and plate can be surveyed by stringent outdoor use environment endurance quality
Examination, is suitble to the use of various plank roads.
Summary of the invention
It is an object of the present invention to provide a kind of fiber reinforcement silicate plates for outdoor plank road.Traditional adopts
Plank road service life with wooden plank road plate and wood plastics composite plank road plate is short, and silicate material has better weather resistance, but
It is that silicate light weight board shock resistance is lower, Yi Fasheng brittle failure.Fiber reinforcement silicate plate of the invention be have compared with
The high-strength light plate of high impact properties can be tested by stringent outdoor use environment endurance quality, be suitble to various plank roads
Use.Meanwhile plate surface forms natural wood grain, plate entire body color or surface color can also be tuned into the face of various timber
Color, for the density and natural wood of plate also substantially in a grade, the plank road natural sense manufactured with it is fine.
It is another object of the present invention to provide a kind of preparations of 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 plate frost resistance is poor, and the present invention passes through formula design, technique
Improve and equipment adjusts, realizes the production with grained 20mm~40mm fiber reinforcement silicate plate, this plate has
Excellent physical and mechanical property can be used as outdoor plank road plate and use.
Third object of the present invention is to provide a kind of application of fiber reinforcement silicate plate for outdoor plank road.
In order to achieve the above first purpose, the present invention adopts the following technical solutions:

4) fiber reinforcement silicate plank road plate surface has natural wood grain, and can be according to demand by plate entire body or table
Surface treatment is at various imitation wood colors, and the density and natural wood of plate are also substantially in a grade, so plate nature texture is very strong,
It is suitble to the use including occasions such as urban landscape plank roads.
5) fiber reinforcement silicate plank road plate physical and mechanical property is excellent, and easy processing and installation.Make in general plank road
In, it can keep constructing with the consistent system of anticorrosive wood substantially, not will increase additional system cost.Ordinary circumstance is general
Plank road system, can be than using the low of anticorrosive wood using silicate plank road plate total cost.For example use the silicic acid of 25mm~30mm
Salt plank road plate manufacture landscape plank road, and using 40mm anticorrosive wood system performance it is close, but comprehensive cost the former be only the latter
70%, in addition the advantage of late maintenance cost, from cost consideration, fiber reinforcement silicate plank road plate is also the fine of wooden footway
Substitute.Belong to the outdoor anti-corrosion plank road of a new generation.
