Embodiment 1

[0060] PA-6-GF30-01 (manufactured by Daicel Polymer Co., Ltd.), which is a polyamide 6 resin with 30% by mass of glass fiber added, using a 2-screw kneading extruder ("HK25D-41" manufactured by "Parker Polymer Co., Ltd.") ) and graphene oxide (manufactured by "Tokyo Chemical Industry Co., Ltd.", model: G0443, 0.1% by mass relative to the total mass of the resin composition) were melt-kneaded to form pellets.

Embodiment 2 and 3

[0062] Resins were produced in the same manner as in Example 1, except that the amount of graphene oxide added was changed to 1% by mass (Example 2) and 3% by mass (Example 3) relative to the total mass of the resin composition. Composition pellets.

Abstract

The invention provides a resin compound, the finished product of the resin compound, and the joint structure of the finished product of the resin compound. The resin compound has a good thermal stability and a good binding performance between silicone sealing materials without damaging the strength of the finished product. The resin compound comprises polyamide resin and oxidized graphene. The resin compound is provided with the thermal stability brought by the oxidized graphene and the good adhesive performance between the silicone sealing material. The strength of the finished product after the finishing is not damaged. The invention provides the finished product of the resin compound, the finished product of the resin compound, and the joint part connected with the finished product, and the joint structure of the finished product of the resin compound connected by the joint part by the hardening object of the liquid-state hard silicon rubber compound.

Description

technical field [0001] The present invention relates to a resin composition, in particular, to a resin composition comprising a polyamide resin and having excellent mechanical properties and heat resistance, a molded product of the resin composition, and a molded product of the resin composition Joint construction. Background technique [0002] Polyamide resins such as nylon 6 and nylon 66 have excellent properties such as mechanical properties and heat resistance, and are used in many applications as engineering plastics. [0003] However, although it is a polyamide resin having excellent heat resistance, when it is continuously exposed to high temperature for a long period of time as in the case of automotive parts, the resin reacts with oxygen in the atmosphere when heated and dies. Deterioration by heat aging. [0004] Heat aging is considered to occur because hydrogen peroxide formed by the reaction of hydrogen and oxygen occurring on the skeleton carbon of the resin ...
