Embodiment 1

[0038] DX 2002 (manufactured by Polyplastics Co., Ltd., polybutylene terephthalate) was used as a molded body, and main agent XNR5002 / curing agent XNH5002 (manufactured by Nagase ChemteX Corporation) was used as an adhesive. As an adhesion pretreatment, the molded body was immersed in the main agent XNR5002, and immersed at 150°C for 1 hour. After the pretreatment, the bonding treatment is performed using a common bonding method, and curing is carried out under the curing conditions of 150° C. and 3 hours. After curing, a bond strength test was carried out after 24 hours.

Embodiment 2

[0040] Except for using DN M90-44 (Polyplastics Co., Ltd., polyacetal) as the molded body, the bonding pretreatment and bonding treatment were performed in the same manner as in Example 1, and bonding was carried out 24 hours after curing. Bonding strength test.

Embodiment 3

[0042] Except for using FN 0220A9 (Polyplastics Co., Ltd., polyphenylene sulfide) as the molded body, the same method as in Example 1 was used for adhesion pretreatment and adhesion treatment, and adhesion was carried out after 24 hours after curing. strength test.

Abstract

The invention provides a cementing method of crystallinity resin forming body, a method for simply cementing hard-cementation crystallinity resin forming body with full cementation force. Concretely the hot-curing cementing agent is used to cement the crystallinity resin forming bodies or crystallinity resin forming body and the other parts, the cementing agent is cured, after or when the cementing ingredient soaks into the cementing surface of the forming body.

Description

technical field [0001] The present invention relates to a bonding method for bonding a difficult-to-bond crystalline resin with a thermosetting adhesive. Background technique [0002] Polyacetal resin (POM), polybutylene terephthalate resin (PBT), and polyphenylene sulfide resin (PPS) have excellent mechanical properties, electrical properties, and other physical and chemical properties, as well as good processability, so These are collectively called engineering plastics and are used in a wide range of applications such as automobiles and electrical and electronic components. The POM, PBT, and PPS can be used alone in various molded products, and are widely used by improving their properties, especially mechanical properties, by adding various reinforcements, additives, etc., depending on the application field. However, the bonding strength between POM, PBT, and PPS and other resins, especially the bonding strength with epoxy resin is low, so for example, between POM, PBT,...
