Problems solved by technology

[0008] However, in this method, the plant fiber is once swollen in the chemical treatment process, and the chemical substance is then put into the processing machine after drying. Therefore, although it is improved compared with the above method, the process remains the same. Complicated, there is a limit to cost reduction

Embodiment 1

[0332] Cellulose-reinforced thermoplastic resins were prepared by the following procedure.

[0333] 1) Preparation process of cellulose composition

[0334] After dispersing 90 parts by mass of cellulose A in an acetone solvent and mixing 10 parts by mass of ionic compound A, the mixture was stirred every few hours and left to stand in a container with a lid for more than 12 hours.

[0335] Thereafter, the lid of the container was opened, and the acetone solvent was dried. After the acetone solvent was almost removed, it was further stored in a thermostat at 80° C. for 12 hours or more in order to dry the water.

[0336]2) Kneading process of cellulose composition and thermoplastic synthetic resin (production of cellulose-reinforced thermoplastic resin composition)

[0337] Feed the thermoplastic synthetic resin B into the twin-screw extruder [KZW15TW-45MG-NH manufactured by TECHNOVEL Co., Ltd.] at an outlet temperature of 150°C and a rate of 300 g / hour, while using the secon...

Embodiment 2

[0343] Without performing the step 3) of Example 1, a cellulose-reinforced thermoplastic resin composition containing one of the thermoplastic synthetic resins obtained in 2) was produced.

Embodiment 3

[0345] In the process of 1) of Example 1, 0.1 parts by mass of ionic compound A is compounded with respect to 99.9 parts by mass of cellulose A; and, in the process of 2), thermoplastic synthetic resin B is used instead of thermoplastic synthetic resin A and B were resins mixed so that the mass ratio was 499:1. A cellulose-reinforced thermoplastic resin composition containing two types of thermoplastic synthetic resins was prepared and produced in the same manner as in Example 2.

Abstract

This thermoplastic resin composition contains a thermoplastic synthetic resin, cellulose and an ion compound, wherein, the cellulose content is 1-100 parts by mass per 100 parts by mass of the thermoplastic resin 100, and the content of the ion compound is at least 0.001 times and less than 1.000 times the cellulose. Also provided are: a thermoplastic resin composition production method, a cellulose-reinforced resin molded product, and a cellulose-reinforced resin molded product manufacturing method.

Description

technical field [0001] The present invention relates to a thermoplastic resin composition, a method for producing the thermoplastic resin composition, a cellulose-reinforced resin molded article, and a method for producing a cellulose-reinforced resin molded article. [0002] More specifically, it relates to a thermoplastic resin composition useful for a cellulose-reinforced resin molded article containing cellulose, particularly plant fiber cellulose, and an ionic compound, a method for producing the thermoplastic resin composition, a cellulose-reinforced resin molded article, and a cellulose-reinforced resin molded article. A method for producing a cellulose-reinforced resin molded article. Background technique [0003] As for cellulose, it is known that the mechanical properties are improved by making it finer to a minute size, and that it becomes a material having an extremely high modulus of elasticity and high strength when it is made finer to a nanometer size. Resear...
