Problems solved by technology

However, cellulose fiber has very high hydrophilicity, so it lacks affinity with highly hydrophobic resins such as polypropylene and polyethylene, and it cannot be mixed uniformly only by mechanical kneading using a twin-screw extruder or the like.
Therefore, the mechanical properties of the obtained composite material are not necessarily satisfactory and are insufficient
[0004] Generally, when a thermoplastic resin with high hydrophobicity such as polyethylene and polypropylene is used to manufacture a molding material containing cellulose fibers, the dispersibility of the cellulose fibers is poor, and it is very difficult to obtain further mechanical strength.

Embodiment 1

[0272] A thermoplastic resin composition composed of 11 parts by mass of cellulose, 1 part by mass of maleic anhydride-modified polyethylene A, and 0.1 part by mass of dialkyl peroxide A was used in a twin-screw extruder with respect to 100 parts by mass of high-density polyethylene. [KZW15TW-45MG-NH manufactured by TECHNOVEL CO., LTD.] was heated and kneaded to obtain pellets of cellulose-reinforced thermoplastic resin.

[0273] Next, a test piece as a molded product for tensile strength evaluation was prepared using an injection molding machine [Robot shot α-30C manufactured by FANUC CORPORATION] with respect to the above-mentioned pellets.

Embodiment 2～5

[0275] In the thermoplastic resin composition of Example 1, except that the compounding amount of the maleic anhydride-modified polyethylene A was changed as shown in the following Table 1, moldings for tensile strength evaluation were produced in the same manner as in Example 1. sample of the product.

Embodiment 6

[0277] In the thermoplastic resin composition of Example 1, 11 parts by mass of cellulose, 2 parts by mass of maleic anhydride-modified polyethylene A, and 0.05 parts by mass of dialkyl peroxide A were changed to 100 parts by mass of high-density polyethylene. Except that, a test piece as a molded product for tensile strength evaluation was produced in the same manner as in Example 1.
