Problems solved by technology

To put it bluntly about this result, processing ① requires more effort because sufficient integral strength does not appear, and processing ② although adhesive bonding has good results, it is more difficult to use other methods for forming holes than processing as a simple method. ① Poor results, indicating that only the size of the surface area cannot achieve the results

experiment example 1

[0081] Commercially available A 5052 / H38 aluminum alloy plates with a thickness of 1 mm were purchased and cut into rectangular pieces of 100 mm×25 mm. In 1 liter of ethanol with ultrasonic waves, the above-mentioned aluminum sheet was soaked for 10 minutes, taken out, immersed in 4 liters of tap water and stirred, poured on a plastic basket and rinsed with tap water. Then, immerse in 2% caustic soda aqueous solution for 2 minutes, wash with ion-exchanged water, immerse in 1% hydrochloric acid aqueous solution for 1 minute to neutralize, immerse in 4 liters of ion-exchanged water, wash with water, and then rinse with ion-exchanged water rinse with running water.

[0082] 1 liter of a 2% aqueous ammonia solution was prepared, and a separately prepared 1% caustic soda aqueous solution was added dropwise, and the pH was adjusted to 11.0 at 50° C. while stirring. Immerse the original aluminum alloy in an aqueous solution of pH 11.0 for 2 minutes, and thoroughly wash it with ion-e...

experiment example 2

[0086] A thermoplastic resin composition composed of 60% of polymer alloy containing 80% of PBT, 20% of PET, 20% of glass fiber and 20% of glass powder filler was produced by using a twin-screw extruder and a granulator. A rectangular molded product with a thickness of 3 mm and a thickness of 100 mm × 25 mm was obtained by injection molding from the end of the rectangle, and the longitudinal and transverse linear expansion coefficients of the molded product were measured between 0 ° C and 60 ° C. As a result, the average value of the linear expansion coefficient in the longitudinal direction is 2.1~2.3~10 -5 ℃ -1 , Horizontal is 3.7~3.9×10 -5 ℃ -1 , the vertical and horizontal average is 3.0×10 -5 ℃ -1 .

experiment example 3

[0088] The thermoplastic resin composition granules obtained in Experimental Example 2 were used as raw materials for injection molding to obtain image 3 Indicates the plate-shaped resin molded product. like Figure 4 As shown, the resin molded product 1 and the aluminum alloy sheet 2 were bonded with an adhesive to obtain a test piece 3 . Before this bonding, the resin molded product 1 was ground on a smooth iron plate using calcium carbonate with an average diameter of 25 μm and a small amount of water to grind the portion to be joined.

[0089] In addition, it was ground with calcium carbonate having an average diameter of 5 μm and a small amount of water, and washed sufficiently with tap water to which ultrasonic waves were added. After leaving to stand in a blow dryer at 50° C. for 6 hours, it was stored in a desiccator for drying to which concentrated sulfuric acid was added. In addition, the aluminum alloy sheet 2 obtained in Experimental Example 1 was also stored i...

Abstract

The invention relates to a complex, which is characterized in that the complex consists of an aluminium alloy shape and a thermoplastic resin combination; the roughness of surface of the complex is more than 5 to 50 Mu m; the surface is provided with the aluminium alloy shape with minute recessed parts or raised parts, the diameter of which is less than 1 Mu m; the aluminium alloy shape is fixed through the recessed parts or raised parts; with the longitudinal and transverse average coefficientof linear expansion ranging from 2X<-5> DEG C<-1> to 4X<-5> DEG C<-1>, the thermoplastic resin combination is primarily made of polybutylene terephthalate resin or polyphenyl thioether; as the thermoplastic resin combination is not peeled off easily from the aluminium alloy shape, the invention has the advantages of metal enclosers and synthetic resin structures in electronic machines and electric appliances. The production efficiency is high, and the complex can be produced on large scale with shape and structure to be designed freely.
