After completion, obtain the mixed powder for standby; Through the above ultrafine pulverization treatment, the materials can be pulverized at a low temperature state, increasing the specific surface area of the materials, and correspondingly increasing the adsorption and solubility, etc., without polluting the environment.

[0007] (2) Modified composite treatment: After heating and melting the mixed powder prepared in the above steps, 25 parts by weight of calcium carbonate, 0.2 parts of terpene, 18 parts of clay, 6 parts of asphalt and 10 parts of reinforcing filler are added to the molten material and stirred evenly. After cooling, it is cut into sheet-shaped polymer damping materials.

[0008] (3)Forming and compounding operation: The prepared sheet-shaped polymer damping material is pressed together with the upper bottom plate and the lower bottom plate, and glued under the baking of water vapor to make the required bamboo floor.

[0009] Preferably, during the ultrafine pulverization treatment in step (1), the rotation speed of the pulverizer is controlled at 10000 - 12000 rpm, and the pulverization treatment time is 10 - 20 min.

[0010] Preferably, the preparation method of the reinforcing material in step (2) includes the following steps: Weigh 10 - 20% glass fiber, 10 - 25% basalt fiber, 12 - 22% carbon fiber, 10 - 15% artemisia annua and 15 - 25% dandelion in corresponding parts by weight after pulverization, conduct continuous flash explosion treatment, take out the mixture after completion, and then dry it to obtain the reinforcing material for standby.

[0012] By adopting the above technical scheme, the synergistic effect between components can be promoted, and the effect of the reinforcing material can be fully utilized.

[0013] Preferably, in the forming and compounding operation in step (3), the temperature of the water vapor is 100 - 105 °C, and the baking time is 40 - 45 min.

[0014] Through the above operations, while effectively compounding the components, the bottom plate and the interlayer can be moistened, and the use of water vapor drying can reduce the probability of bursting.

[0015] (III)Beneficial effects The present invention provides a manufacturing process for a bamboo floor for buses. It has the following beneficial effects: 1. The manufacturing process of the bamboo floor for buses pulverizes at a low temperature to obtain ultrafine powder with a uniform particle size distribution, increasing the specific surface area of the micro powder, and correspondingly increasing the adsorption, solubility, etc., which helps the dissolution of active ingredients. Moreover, the ultrafine pulverization treatment is carried out in a closed system, which not only avoids the pollution of the micro powder to the surrounding environment but also prevents the pollution of the product by dust in the air, meeting the safe and environmental protection technical operations.

[0016] 2. The manufacturing process of the bamboo floor for buses. Using flash explosion treatment can destroy the gum in the fibers, improve the fiber separation effect, significantly increase the ratio of cellulose, which is of great significance for improving the purity and performance of the fibers, thereby enhancing the damping effect of the interlayer, and forming tiny exhaust channels to improve the air permeability of the material and prevent the floor from bursting at high temperatures.
