Problems solved by technology

Although these methods have no problems in the joint strength and the airtightness of the joint part, the gas derived from halogen is generated during the etching process, so it is necessary to consider that the surrounding metal parts and devices will not be corroded and the surrounding environment will not be affected. Pollution countermeasures and other issues
[0020] In addition, although Patent Document 8 describes the anchoring effect and chemical action of a porous film having a hydroxyl group and the effect of using a thermoplastic resin composition added with a thermoplastic elastomer, Patent Document 9 describes the addition of a polyarylene sulfide resin. Adhesion between resin materials containing olefinic copolymers and the like, and metals, however, the effect of the combination of metal surface treatment and functional groups on the resin composition on joint strength and adhesion is not clear

Embodiment 1

[0114] (1) Fabrication of aluminum base material after surface treatment

[0115] An aluminum substrate having a size of 50 mm×25 mm was cut out from a commercially available aluminum plate (A5052; plate thickness 2.0 mm). Next, by the treatment method A (formation of the zinc-containing film), a surface-treated aluminum substrate for a test in which an oxygen-containing film containing zinc element was formed on the surface was produced.

[0116] With regard to the obtained surface-treated aluminum substrate, the oxygen content, oxygen strength, and film thickness of the oxygen-containing film were measured.

[0117] The results are shown in Table 1.

[0118] (2) Resin composition

[0119] As the thermoplastic resin composition, a PPS-based resin composition [PPS (1)] containing additive compound a and additive compound b and 50% of an inorganic filler shown in Table 1 was used. The PPS resin composition [PPS(1)] has a melt viscosity of 230Pa·s (310°C, 1000s -1 ) resin co...

Embodiment 2～47

[0128] For the aluminum base material, film formation treatment of oxygen-containing film, oxygen-containing film, resin composition, and resin molding conditions as shown in Tables 1 to 8, respectively, an evaluation test of bonding strength was performed in the same manner as in Example 1.

[0129] In addition, 30wt% HNO was used in Example 29 3 In the solution and Example 30, 0.1 M NaOH water was used to adjust the conductivity of the hot water to the values ​​shown in Table 5.

[0130] In addition, in Examples 3, 4, 12 to 14, 18, 23, 24, 29 to 34, 42, 43, 45, and 46, the same PPS-based resin composition [PPS (1)] as in Example 1 was used. . In addition, in Example 2 using PPS resin [PPS(2)], 40% by mass of glass-based filler was added to the resin composition, and in Examples 5-9, 15-17, 19- 22, 25 to 28, 35, 36, 44, and 47, and Examples 10 and 11 using PP, 30% by mass of glass filler was added to the resin composition, and in Examples 37 to 47 using POM In 40, 25% by m...

Abstract

Provided is a metal-resin bonded body with which excellent bonding strength can be achieved, strength is not reduced after being subjected to a durability test, and excellent bonding strength can be maintained for a long time. This metal-resin bonded body is provided with: a metal base material: an oxygen-containing film which includes oxygen, and which is formed on a surface of the metal base material by being subjected to processing in which the oxygen content thereof is intentionally increased; and a resin moulded body which is bonded to a top of the oxygen-containing film, and which is formed using a thermoplastic resin composition including an additive compound having a specific functional group that reacts with the oxygen-containing film. The functional group in the additive compound is at least one selected from the group consisting of a carboxyl group and salts and esters thereof, an epoxy group, a glycidyl group, an isocyanate group, a carbodiimide group, an amino group and salts thereof, and an acid anhydride group and esters thereof.

Description

technical field [0001] The present invention relates to a metal-resin bonded body in which a metal base material made of metal and a resin molded body made of thermoplastic resin are integrally and firmly bonded by injection molding or thermocompression bonding of thermoplastic resin, and a method for producing the same. Background technique [0002] In recent years, in the fields of various sensor parts of automobiles, home appliance parts, industrial machinery parts, etc., copper substrates made of copper or copper alloys with very high heat dissipation and conductivity have been used due to their high heat dissipation and compared with other metals. A metal-resin bonded body in which an aluminum substrate made of lightweight aluminum or an aluminum alloy is integrally bonded to a resin molded body made of a thermoplastic resin having high insulating performance, light weight, and low cost is widely used, and its use is expanding. [0003] Conventionally, as a metal-resin ...
