Embodiment 1

[0021] Embodiment 1 of the manufacture method of a kind of bamboo fiber composite board plate of the present invention is:

[0022] Step 1: The equivalent diameter is 0.5mm and the bamboo fiber of length 200mm and thermoplastic short fiber are carried out mixing and twisting into bamboo-plastic blended rope with bamboo 20% plastic 80% mass ratio;

[0023] Step 2: uniformly mixing 70% of thermoplastic powder and 30% of bamboo fiber powder by mass ratio to form bamboo-plastic mixed powder;

[0024] Step 3: In the autoclave, cross the bamboo-plastic blended rope according to the "warp" and "weft" at a certain angle and the number of meshes to form a plurality of tendons, and apply a tension of 50 MPa to the bamboo-plastic blended rope;

[0025] Step 4: Fill the bamboo-plastic mixed powder into the autoclave, apply a pressure of 20MPa, and a temperature of 230°C for 30 minutes;

[0026] Step 5: Keep the tension cool to room temperature.

Embodiment 2

[0028] Step 1: the bamboo green fiber with an equivalent diameter of 0.3mm and a length of 100mm and thermoplastic short fibers are mixed and twisted into a bamboo-plastic blended rope with a mass ratio of 50% bamboo to 50% plastic;

[0029] Step 2: uniformly mixing 50% of thermoplastic powder and 50% of bamboo fiber powder by mass to form bamboo-plastic mixed powder;

[0030] Step 3: In the autoclave, cross the bamboo-plastic blended rope according to the "warp" and "weft" at a certain angle and the number of meshes to form multiple tendons, and apply a tension of 30 MPa to the bamboo-plastic blended rope;

[0031] Step 4: Fill the mixed powder of bamboo and plastic into the autoclave, apply a pressure of 15MPa and a temperature of 180°C for 20 minutes;

[0032] Step 5: Keep the tension cool to room temperature.

Embodiment 3

[0034] Step 1: the bamboo fiber with an equivalent diameter of 0.2mm and a length of 50mm and thermoplastic short fibers are mixed and twisted into a bamboo-plastic spinning rope with a mass ratio of 80% of bamboo and 20% of plastic;

[0035] Step 2: uniformly mix 30% of thermoplastic powder and 70% of bamboo fiber powder into bamboo-plastic mixed powder;

[0036] Step 3: In the autoclave, cross the bamboo-plastic blended rope according to the "warp" and "weft" at a certain angle and the number of meshes to form a plurality of ribs, and apply a tension of 10 MPa to the bamboo-plastic blended rope;

[0037] Step 4: Fill the mixed powder of bamboo and plastic into the autoclave, apply a pressure of 10MPa and a temperature of 140°C for 10 minutes;

[0038] Step 5: Keep the tension cool to room temperature.

Abstract

The invention provides a manufacturing method of a super-strong bamboo fiber composite board. The manufacturing method includes the steps that bamboo fibers with the equivalent diameter of (0.2-0.5) mm and the length of (30-100) mm are blended with thermoplastic plastic short fibers according to the mass ratio of (70-30)%:(30-70)% to form a blended rope, and uniformly mixing is conducted on thermoplastic powder (80-20)% and bamboo fiber powder (20-80)% to form mixed powder. By means of the manufacturing method of the super-strong bamboo fiber composite board, a reinforced bamboo-plastic composite material is prepared by taking the blended rope as a reinforcing rib and taking the mixed powder as filler, so that the application limitation of a traditional bamboo material is broken through, the multifunction property of the bamboo fiber material is achieved, and the additional value of the bamboo fiber material is greatly improved.

Description

technical field [0001] The invention relates to a manufacturing method of a super-strong bamboo fiber composite board, in particular to a reinforced composite board prepared with bamboo fiber and thermoplastic as main raw materials. Background technique [0002] Bamboo fiber is a kind of natural fiber (also known as bamboo fiber) derived from bamboo. It has the advantages of low density, high strength, high rigidity, and wear resistance. It is a green, renewable, and degradable plant fiber. According to data, the tensile strength of bamboo fiber prepared by advanced technology is equivalent to that of carbon steel, and the mechanical properties of composite materials prepared by bamboo fiber are comparable to those of glass fiber reinforced plastics. Therefore, bamboo fiber is also called "natural glass fiber". [0003] Using bamboo fiber as a reinforcing material and thermoplastic as a matrix for composite, it can be prepared into a thermoplastic bamboo fiber composite mate...
