preparation example Construction

[0019] (1) The preparation method of the thermoplastic resin composition involved in this embodiment includes: step (a), mixing carbon nanofibers in an elastomer containing unsaturated bonds or groups that have affinity for carbon nanofibers and Disperse the composite elastomer by shearing force to form a composite elastomer; and step (b) kneading the composite elastomer and the thermoplastic resin.

[0020] (2) The preparation method of the thermoplastic resin composition involved in this embodiment includes: step (c), mixing the thermoplastic resin with an elastomer containing unsaturated bonds or groups that have affinity for carbon nanofibers; And in step (d), the mixture of the thermoplastic resin and the elastomer is mixed with carbon nanofibers and dispersed by shearing force.

[0021] The thermoplastic resin composition involved in this embodiment includes: a matrix containing a thermoplastic resin and an elastomer; and carbon nanofibers, the carbon nanofibers are disperse...

Embodiment

[0082] Hereinafter, embodiments of the present invention will be described in detail, but the present invention is not limited to this.

[0083] (1) Preparation of samples of Examples 1 to 6

[0084] Process (a):

[0085] Put the amount of elastomer shown in Table 1 into a 6-inch open mill roll (roll temperature 10-50°C), wind it on a roll with a roll gap of 1mm, put and mix carbon nanofibers into the elastomer, and put the roll Adjust the gap to 0.1mm and perform 5 thin-layer passes to obtain a composite elastomer in which carbon nanofibers are dispersed in the elastomer. The roller rotation speed was set to 22 rpm / 20 rpm.

[0086] Process (b):

[0087] The composite elastomer was wound on a 6-inch open-rolling roll with a heated hot roll, the thermoplastic resin in the amount shown in Table 1 was put in and mixed, and the thermoplastic resin with a thickness of 1.2 mm was extruded in a sheet form. At this time, the heat roller temperature was set to 180°C in Examples 1, 2, 5, an...

Abstract

A thermoplastic resin composition including: a matrix including a thermoplastic resin and an elastomer; and carbon nanofibers dispersed in the matrix. The elastomer includes an unsaturated bond or a group having affinity to the carbon nanofibers.

Description

Technical field [0001] The invention relates to a thermoplastic resin composition and a preparation method thereof. Background technique [0002] Generally, as a composite material, combining a matrix material and reinforcing fibers or reinforcing particles can obtain physical properties corresponding to different uses. In particular, in the fields of semiconductor manufacturing equipment, optical equipment, and ultra-fine processing equipment, it is required to reduce the influence of thermal expansion on components. Therefore, composite materials made of various reinforcing fibers such as carbon fibers have been proposed. (For example, refer to International Publication No. 00-64668 pamphlet). [0003] In addition, as a composite material already proposed by the present inventors, it is a carbon fiber composite material in which carbon nanofibers are uniformly dispersed in an elastomer (for example, refer to Japanese Patent Application Laid-Open No. 2005-68386). This carbon fib...
