Problems solved by technology

Among them, BYD Co., Ltd. proposed to directly inject polyamide resin on the surface of the nano-treated aluminum alloy to obtain a directly bonded combination. However, his technology is limited to aluminum alloy and polyamide resin; Dacheng Plus Co., Ltd. through soaking Metals such as aluminum alloys and stainless steels can be directly combined with resins by methods such as etching and etching. This technology can extend metals to metals such as aluminum alloys and stainless steels, and resins can also be extended to relatively common engineering resins. However, it cannot cover general engineering applications. Other metal materials, such as iron and its alloys, magnesium and its alloys, zinc and its alloys, titanium and its alloys, copper and its alloys, nickel and its alloys and other metals, and both of them have a common drawback, a Metal materials can only be treated in a specific way, and cannot be used in common with each other, resulting in different process solutions for different substrates, which increases the cost of use and limits product applications

Embodiment 1

[0029] Example 1, such as Figure 1~3 As shown, a method for preparing a combination 3 of metal 1 and resin 2 comprises the following steps:

[0030] Step 1. Deposit a layer of microporous layer on the surface of metal 1 by electrodeposition, wherein the microporous layer is set as metal 1 nickel microporous layer or metal 1 nickel alloy microporous layer;

[0031] Step 2: Combining resin 2 with the surface of metal 1 treated in step 1 by injection molding, so as to obtain a combination 3 of metal 1 and resin 2 .

[0032] Specifically, (1) Pre-treatment: Cut the commercially available 1.0mm thick 6063 aluminum into many small pieces of 15mm×50mm, randomly take ten pieces and hang them firmly on the stainless steel hanger covered with electroplating glue; then Soak in the special degreasing agent for aluminum materials for 300 seconds, then wash with water, the temperature is set to 60°C; then soak in 65g / l sodium hydroxide aqueous solution for 40 seconds, then wash with water...

Embodiment 2

[0036] Embodiment 2, different from Embodiment 1, is that the metal of this embodiment is set to a magnesium alloy, and the commercially available 1.0mm thick AZ91D magnesium alloy is cut into many small pieces of 15mm * 50mm, and the magnesium alloy degreaser is used at 60 Soak for 300 seconds at ℃. The ten groups of magnesium alloy and resin direct combination of this experimental case were obtained. The average peel strength of ten groups of combination resin and magnesium alloy was measured to be 22.4MPa.

[0037] Others are the same as in Embodiment 1, and will not be repeated here.

Embodiment 3

[0038] Embodiment 3 is different from Embodiment 1 in that the metal of this embodiment is set to a zinc alloy, and its specific preparation steps are as follows:

[0039] (1) Pretreatment: Cut the commercially available 1.0mm thick ZA4-1 zinc alloy into many small pieces of 15mm×50mm, randomly take ten pieces and hang them firmly on the stainless steel hanger covered with electroplating glue; then soak After 300 seconds in the special degreasing agent for zinc alloy, wash it with water, and the temperature is set to 60°C; then soak it in 15g / l ammonium bifluoride aqueous solution for 30 seconds, then wash it with water, and the temperature is set at 40°C;

[0040] (2) Pre-deposition: Soak the zinc alloy treated in step (1) in 5g / l citric acid solution for 30 seconds, wash it with water, and put it in the pre-nickel plating bath at a cathode current density of 1.2A / dm at room temperature. 2 After galvanic deposition for 300 seconds, rinse with water, pre-nickel plating tank: 9...

Abstract

The invention belongs to the technical field of material, and particularly relates to a preparation method of a combined body of metal and resin. The preparation method comprises the following steps: firstly, depositing a micro pore layer on the surface of metal via an electric deposition method, wherein the micro pore layer is arranged to be a metal nickel micro pore layer or a metal nickel alloy micro pore layer; and secondly, combining resin with the surface of the metal processed in the step one in an injection molding mode for molding so as to obtain the combined body of metal and resin. According to the invention, the technical difficulties that multiple metal not suitable for surface treatment cannot be firmly combined with resin and different technologies are required for different metal are solved by an electric deposition method, and the diversification need of market is met; in addition, the invention also discloses the combined body of metal and resin.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a method for preparing a combination of metal and resin and a product. Background technique [0002] In the fields of mobile communication equipment, electronic and electrical equipment, automotive machinery, etc., it is often encountered the problem of firmly combining metal parts and engineering resins. The traditional solution is to use adhesives or manufacture a large number of rivets, undercuts, Methods such as holes, however, not only increase the process flow and product size virtually, but also do not have high bonding strength. Therefore, the method of directly combining engineering resin and metal without using adhesives or manufacturing a large number of rivets, undercuts, holes, etc. has gradually become a research hotspot. [0003] Both BYD Co., Ltd. and Japan's Dacheng Plus Co., Ltd. have applied for some patents such as CN103286909A, CN101568420A, CN...
