preparation example Construction

[0029] In another typical embodiment of the present application, there is also provided a method for preparing a composite material, the preparation method comprising: matrix material, reinforcing material, auxiliary material and their proportions in the composition of any one of the above composite materials Mixing to obtain a mixture; extruding and granulating the mixture to obtain a semi-finished product; injecting, extruding or molding the semi-finished product to obtain a composite material.

[0030] The above-mentioned preparation method uses the composition of the above-mentioned composite material, uses the natural product bamboo fiber and shell powder as the reinforcing material, and cooperates the reinforcing material with the thermoplastic resin of the matrix material according to the above-mentioned ratio, and passes the bamboo fiber and shell powder and the thermoplastic resin. The synergistic effect among them makes the composite material prepared by the compositi...

Embodiment 1

[0047] According to the raw material ratio in Table 2 and the raw materials in Table 3, the bamboo fiber reinforced composite material composition of Example 1 is formed, and the reinforcing material is first placed in a hot mixing pot at 80°C and pre-prepared at a speed of 900 rpm / min. After stirring for 1 min, add a coupling agent to the pre-stirred reinforcing material, and then stir at a speed of 1000 rpm for 3 min to obtain the first premix; add the base material and the rest of the auxiliary materials to the first premix to The rotating speed of 1200 rev / min was stirred for 5min to obtain the mixture;

[0048] The mixture is extruded and granulated at 230°C to obtain a semi-finished product;

[0049] The semi-finished product is injected, extruded or molded to obtain the bamboo fiber reinforced composite material.

Embodiment 2

[0051] According to the raw material ratio in Table 2 and the raw materials in Table 3, the bamboo fiber reinforced composite material composition of Example 2 is formed, and the reinforcing material is first placed in a hot mixing pot at 110°C and pre-prepared at a speed of 950 rpm / min. After stirring for 3 minutes, add a coupling agent to the pre-stirred reinforcing material, and then stir for 1 minute at a speed of 1200 rpm to obtain the first premix; add the matrix material and the rest of the auxiliary materials to the first premix to Stir at a speed of 1000 rpm / min for 5 min to obtain a mixture;

[0052] The mixture is extruded and granulated at 180°C to obtain a semi-finished product;

[0053] The semi-finished product is injected, extruded or molded to obtain the bamboo fiber reinforced composite material.

Abstract

The invention provides a bamboo fiber reinforced composite material composition, and a preparation method of a bamboo fiber reinforced composite material. The composition comprises, by weight, 25-80 parts of a base material, 10-70 parts of a reinforcement material and auxiliary materials, and the base material comprises bamboo fibers and shell powder. The bamboo fibers in the composition are a renewable resource, and have an antibiosis and deodorization effects, and the shell powder has very strong regeneration ability, and is a natural environmentally-friendly material. The bamboo fibers and the shell powder which are natural products are used as the reinforcement material, and the reinforcement material and the matrix material thermoplastic resin are mixed according to above proportions, and synergism of the bamboo fibers, the shell powder and the thermoplastic resin makes the composite material prepared by using the composition have the advantages of degradability, environmentally-friendly performance, good tensile strength, good high-temperature resistance, good heat insulation property and good weather resistance.

Description

technical field [0001] The invention relates to the field of materials science, in particular to a bamboo fiber reinforced composite material composition and a preparation method of the bamboo fiber reinforced composite material. Background technique [0002] Composite materials are used in a wide range of fields, especially interior materials in the fields of automobiles, airplanes, and ships, shell materials in the fields of home appliances, daily necessities in the fields of furniture, toys, pallets, and turnover boxes, and alternative materials for daily necessities and construction. , decoration, packaging and garden construction, public places and other fields. [0003] However, most of the modified materials currently used are synthetic plastics or fibers extracted from non-renewable resources such as minerals and petroleum, which are non-degradable and bring a considerable burden to the environment after being discarded. [0004] Therefore, how to improve the enviro...
