Problems solved by technology

Almost simultaneously with the heat generation, the thermoplastic resin is rapidly cooled by contacting the aluminum alloy shape kept at a low mold temperature, but due to the heat generation, the solidification of the resin to be crystallized and solidified is delayed and remains molten. State, sneak into the concave part of the surface of the ultra-fine aluminum alloy shape

[0127] [Adjustment Example 1 (Preparation Example of PPS Composition)]

[0128] In a 50-liter autoclave equipped with a stirrer, 6214 g of Na 2 S 2.9H 2 O and 17,000 g of N-methyl-2-pyrrolidone were slowly heated up to a temperature of 205° C. while stirring under a nitrogen stream, and 1,355 g of water was distilled off. After cooling the system to a temperature of 140° C., 7160 g of p-dichlorobenzene and 5000 g of N-methyl-2-pyrrolidone were added, and the system was sealed under nitrogen flow. The system was heated up to a temperature of 225°C over 2 hours, polymerized at 225°C for 2 hours, then heated up to a temperature of 250°C over 30 minutes, and further polymerized at a temperature of 250°C over 3 hours. After the polymerization was completed, it was cooled to room temperature, and the polymer was separated with a centrifuge. The solid polymer was repeatedly washed with warm water, and dried overnight at a temperature of 100° C. to obtain a PPS composition having a...

Embodiment 1

[0147] Commercially available 1.6 mm thick cold-rolled steel "SPCC smooth" plate was purchased, cut into a plurality of rectangular pieces with a size of 18 mm×45 mm, and used as steel sheets. Through-holes were opened at the ends of the steel sheets, and dozens of copper wires coated with vinyl chloride were passed through. The copper wires were bent and processed so that the steel sheets did not overlap each other, and all were suspended at the same time. The steel sheet was immersed in an aqueous solution containing 7.5% of the aluminum alloy degreasing agent "NE-6 (manufactured by Meltex)" at a temperature of 60° C. for 5 minutes, and washed with tap water (Ota City, Gunma Prefecture).

[0148] Then, a 1.5% sodium hydroxide aqueous solution having a temperature of 40° C. was prepared in a separate immersion tank, and after immersing the steel material piece therein for 1 minute, it was washed with water. Then, an aqueous solution containing 10% of 98% sulfuric acid at a te...

Embodiment 2

[0156] Steel sheets were treated in exactly the same manner as in Example 1 except that hydrazine hydrate 3.5% aqueous solution at 40°C was used instead of hydrazine hydrate 3.5% aqueous solution at 40°C, and the tensile fracture test was performed in the same manner as in Example 1. The shear breaking force was 26 MPa as an average of three samples. The 10,000-fold and 100,000-fold electron microscope photographs of the steel sheet are shown in Figure 4 (a), 4(b). Depend on Figure 4 (b) It can be seen that although the basic shape is the same as that of Example 1, the form of the thin skin attached to the surface of the stepped unevenness is different from that of Example 1. The obtained steel sheet was injection-joined using the PPS composition (1) in exactly the same manner as in Example 1, annealed, and subjected to a tensile test. The average shear breaking force is 25MPa.

Abstract

A composite of a metal with a resin in which the metal and the resin, especially a shaped base made of an ordinary steel material and a resin composition, can be tenaciously bonded and united to each other; and a process for producing the composite. A surface of a shaped ordinary steel material is treated by chemical etching or the like to form a thin iron autoxidation film layer the surface of which almost wholly has ultrafine irregularities. Hydrazine, ammonia, or a water-soluble amine is chemically adsorbed onto the treated steel material. The resultant steel material shape (1) is inserted into an injection die (10), and a specific resin composition (4) is injected thereinto. The surface of the steel material shape (1) may have a thin layer of a metal oxide or metal-phosphorus oxide. By this injection, a composite (7) is obtained in which the ordinary steel material has been tenaciously bonded and united to the resin. The resin composition (4) to be used contains a crystalline polyphenylene sulfide resin (PPS) or polybutylene terephthalate resin (PBT) as the main resin component.

Description

technical field [0001] The present invention relates to complexes generally applicable to mobile machinery, electrical equipment, medical equipment, general machinery, and other manufacturing fields and its manufacturing technology. More specifically, it relates to a composite body formed by integrating a steel material shaped object shaped by various machining processes and a thermoplastic resin composition, and a method for producing the same. Background technique [0002] The technology of integrating metals and synthetic resins is required in a wide range of industries, including parts manufacturing for automobiles, household electrical appliances, and industrial equipment, and a large number of adhesives have been developed for this purpose. Among the proposals are very good adhesives. For example, an adhesive that functions at room temperature or by heating is used to integrally join metal and synthetic resin, and this joining method is currently a common joining tech...
