Embodiment 1

[0047] Chopped basalt fiber reinforced wood-plastic composite material contains the following components by weight based on 100 parts of total weight: basalt fiber: 18 parts; teak wood powder: 57 parts; high-density polyethylene: 25 parts; wherein the diameter of basalt fiber d=13 μm, length L=3 mm.

[0048] refer to figure 1As shown, the preparation process is described as follows: (1), weigh the corresponding basalt fiber and wood-plastic composite material according to the weight of the above table, put them into a double-roll mill after mixing, and plasticize and knead them. During the kneading process, before and after The temperature of the rollers is controlled at 160°C and 170°C respectively, and kneading for 10 minutes;

[0049] (2) Use a pulverizer to pulverize the uniformly plasticized material until the particle diameter of the material does not exceed 20 mm.

[0050] (3) Use a flat vulcanizer to heat and press molding, wipe the used mold clean, place it in the ...

Embodiment 2

[0052] Chopped basalt fiber reinforced wood-plastic composite material contains the following components by weight based on 100 parts of total weight: basalt fiber: 24 parts; teak wood powder: 53 parts; high-density polyethylene: 23 parts; wherein the diameter of basalt fiber d=13 μm, length L=6mm, and the preparation method is the same as that in Example 1.

[0053] The data involved in Examples 3 to 14 are shown in Table 2, wherein d represents the diameter of the basalt fiber, and L represents the length of the basalt fiber. And adopted the same preparation method as Example 1.

[0054] Table 2 List of different components used in Examples 3 to 14.

[0055]

[0056] Wherein in the embodiment that is applied to mixed wood powder, the fiber that adopts is equal weight ratio.

[0057] Depend on figure 2 It can be seen that the added BF content and the chopped length of basalt fiber have obvious effects on the mechanical properties of BF-WPC sheet: under the same content...

Abstract

The invention relates to a basalt fiber reinforced wood-plastic composite material. The composite material is characterized by comprising 5 to 30 parts of chopped basalt fiber with length of 2 to 15 millimeters and diameter of 2 to 25 microns, 21 to 66 parts of wood fiber and 21 to 66 parts of plastic material in part by weight. A preparation method comprises the following steps of: weighing each component according to a proportion, mechanically mixing the components and then feeding the mixture into a double-roll open mill to perform plasticizing and mixing, controlling the temperatures of front and rear rolls at 160 DEG C and 170 DEG C respectively, and mixing the components for 10 minutes till the system is mixed uniformly, namely no BF is observed from the surface; crushing the uniformly plasticized material by using a crusher till the diameters of the particles of the material are not more than 20 millimeters; and heating, mold-pressing and molding the crushed material by using a flat vulcanizing machine to obtain a plate sample. The tensile strength, bending strength and impact strength of the basalt fiber reinforced wood-plastic composite material obtained by the method are improved by over two times, and the composite material has good economic and social benefits.

Description

technical field [0001] The invention relates to a wood-plastic composite material reinforced with chopped basalt fibers and a preparation method thereof. Background technique [0002] Wood Plastic Composites (WPC for short) is made of plant fiber such as wood fiber as reinforcing material, thermoplastic as matrix material, after adding related additives, it is obtained by extrusion, injection molding, molding and other molding methods. WPC maintains the original processing performance, texture and color of wood, and can be widely used in furniture, floors, pallets, doors, windows and automobiles. However, compared with solid wood, the production cost is higher, the energy consumption is 3-4 times higher, the density of the finished board is higher, but the strength and hardness are slightly lower, and the cost performance is lower, which limits its application range. As far as the current performance is concerned, It is also difficult to apply to industries with high perfor...
