Problems solved by technology

However, for parts that use resin materials alone as constituent materials, the replacement of resin materials is approaching the limit due to reasons such as insufficient strength and rigidity at high temperatures, or insufficient resistance to chemical substances.
In addition, there are also attempts to improve the surface texture or anti-rust function by compositing or multi-layering parts composed of metal materials alone and resin materials, but the overall strength of the parts is insufficient due to poor bonding between the metal and resin, or for In the case of parts that come into contact with liquids, the function of the parts may decline due to the liquid permeating or stagnating at the junction between metal and resin

Embodiment 1

[0114] Use the natural convection dryer SONW-450 of Azowan Co., Ltd. set at 200°C to preheat the aluminum test piece surface-treated through treatment 1, and set the test piece at a place where it can be molded. figure 1 In the mold of the composite body, the mold is installed on the injection molding machine SE-100D of Sumitomo Heavy Industries Co., Ltd., and the poly The amide resin composition is introduced into the injection molding machine, and injected into a mold with a mold temperature of 150°C at a resin temperature of 260°C, and after applying a holding pressure of 40MPa for 40 seconds, it is cooled in the mold for 45 seconds to obtain figure 1 complex of shapes. The strength measurement and bondability evaluation of the obtained composite were performed. Moreover, the measurement of the linear expansion coefficient was performed based on the cut-out test piece. The results are shown in Table 1.

Embodiment 2

[0116] A composite was obtained in the same manner as in Example 1 except that (a-1) was 25% by mass and (a-6) was 75% by mass in Example 1. The strength measurement and bondability evaluation of the obtained composite were performed. Moreover, the measurement of the linear expansion coefficient was performed based on the cut-out test piece. The results are shown in Table 1.

Embodiment 3

[0118] A composite was obtained in the same manner as in Example 1 except that (a-1) was 50% by mass and (a-6) was 50% by mass in Example 1. The strength measurement and bondability evaluation of the obtained composite were performed. In addition, the linear expansion coefficient and the crystallization temperature were measured based on the cut-out test pieces. The results are shown in Table 1.

Abstract

The objective of the present invention is to provide a composite which is obtained by firmly bonding a thermoplastic resin and a metal without deteriorating the characteristics of the thermoplastic resin. In order to achieve the objective, the present invention provides a composite obtained by contact bonding a thermoplastic resin composition (A) and a metal (B), wherein the thermoplastic resin composition (A) contains a thermoplastic resin and an inorganic filler that increases the crystallization temperature of the thermoplastic resin by 3 DEG C or more and the metal (B) is a surface-treated metal. It is preferable that the thermoplastic resin is a polyamide resin. It is also preferable that the inorganic filler is composed of at least one substance that is selected from the group consisting of talc, graphite, magnesium oxide, kaolin and calcium carbonate.

Description

technical field [0001] The present invention relates to a composite body of metal and thermoplastic resin. Background technique [0002] In various fields such as automobiles and electrical electronics, engineering plastics can help reduce the weight and cost of parts by replacing the constituent materials of parts that were previously made of metal materials with resin materials. However, for parts that use resin materials alone as constituent materials, the replacement of resin materials is approaching the limit due to reasons such as insufficient strength and rigidity at high temperatures, or insufficient resistance to chemical substances. In addition, there are also attempts to improve the surface texture or anti-rust function by compositing or multi-layering parts composed of metal materials alone and resin materials, but the overall strength of the parts is insufficient due to poor bonding between the metal and resin, or for In the case of parts that come into contact...
