Problems solved by technology

At present, there are no reports on the use of silicate boards for outdoor planks in the market. When using fiber silicate plank boards as plank boards, some technical problems need to be solved, mainly in: 1) Silicate lightweight boards are brittle The material has poor impact resistance, and it is prone to brittle fracture when people run and jump on the plank road, and there is a safety risk in use. Although this risk can be reduced through the cooperation of the system, it increases the cost of the system; 2) Silicate light board The apparent natural texture of the board is far inferior to that of wooden boards, and it is difficult to be accepted in many landscape plank roads that pursue high natural attributes.
[0005] The silicate plate produced by the flow method or the drawing method has high flexural strength, but because it is a multi-layer laminated structure, it is prone to damage to the interlayer structure when used in a freeze-thaw environment

Embodiment 1

[0069] A fiber-reinforced silicate board for outdoor plank road, and its production process is as follows figure 1 shown, including the following steps:

[0070] 1) After pulping and refining the wood pulp board, it is prepared into pulp for later use; the bentonite is emulsified in an emulsifying machine for 1 hour with a concentration of 10%, and the microsilica powder is emulsified in an emulsifying machine for 1 h with a concentration of 30% for standby;

[0071] 2) After each material is mixed in proportion, add water and stir and control the concentration to 10%, form a thin material layer with a thickness of 1.0mm through flow slurry, and then stack each thin material layer through a forming cylinder to form a whole with a thickness of 20mm. Slab; during the multi-layer lamination process of the forming cylinder, the polyacrylamide solution is sprayed uniformly and continuously between each layer, and the spray amount is 200ppm of the dry material weight of the material...

Embodiment 2

[0078] A fiber-reinforced silicate board for outdoor plank road, the preparation steps are the same as those in Example 1, and the difference is:

[0079] In step 2), the concentration after adding water and stirring is 30%, and the plate is made by copying.

[0080] The plate making machine used is a copying plate making machine.

Embodiment 3

[0082] A fiber-reinforced silicate board for outdoor plank road, the preparation steps are the same as those in Example 1, and the difference is:

[0083] In step 2), the concentration after adding water and stirring is 20%, the thickness of the thin material layer is 1.2 mm, the thickness of the slab is 30 mm, and the injection amount of the polyacrylamide solution is 400 ppm of the dry material weight of the material layer.

Abstract

The invention discloses a fiber enhanced silicate sheet material for an outdoor gallery road. The fiber enhanced silicate sheet material is prepared from the following raw materials in percentage by mass: 63 percent to 80 percent of cement, 6 percent to 12 percent of micro-silicon powder, 4 percent to 10 percent of metakaolin, 4 percent to 10 percent of wollastonite, 1.5 percent to 2.2 percent of PVA (Polyvinyl Alcohol) fiber, 3 percent to 5 percent of wood pulp fiber and 0.6 percent to 1.2 percent of bentonite. The fiber enhanced silicate sheet material disclosed by the invention is a lightweight and high-strength sheet material with relatively high impact resistance, and can be suitable for various types of gallery roads through strict outdoor utilization environment endurance performance tests. Meanwhile, natural wood grains are formed on the surface of the sheet material, and the whole body color or surface color of the sheet material can be adjusted into colors of various woods; the density of the sheet material is basically the same level as that of natural wood, and the natural appearance of the gallery roads manufactured by the fiber enhanced silicate sheet material is very good.

Description

technical field [0001] The invention relates to the technical field of silicate plates. More specifically, it relates to a fiber-reinforced silicate board for outdoor plank road and its preparation method and application. Background technique [0002] With the continuous improvement of living and leisure environment, more and more plank roads are built in residential areas or tourist attractions, and a large number of plank road boards are needed. [0003] Walking on the wooden plank road in the park and enjoying the garden landscape is a favorite way of leisure for many citizens. The current wooden plank road and wood-plastic plank road are mainly made of anti-corrosion wood and wood-plastic and a small amount of bamboo plank road, which have many congenital deficiencies, such as short service life, easy to be eaten by insects, perishable, not fireproof, and a lot of precious forest resources, which is not conducive to environmental protection. The laying of fiber silica...
