Abstract

The invention provides a protection material, which comprises a high-temperature-resistant protection film and dustless cloth. The high-temperature-resistant protection film is bonded to the dustless cloth. The invention also provides the fabrication method of a metal-plastic composite part, which includes (1) providing a metal part and a plastic part, and pre-pressing hot-melt adhesive between the metal part and the plastic part; (2) placing the metal member above the plastic part which is provided with a region exposed from the metal part, and arranging a protection material on the metal part, wherein the protection material covers the region of the plastic part exposed from the metal part and the protection material adopts the above protection material; and (3) performing hot-melting to the metal part and the plastic part, cooling, and removing the protection material, to obtain the metal-plastic composite part. The inventive protection material has good high temperature resistance and heat-insulating property, can effectively protect the exposed part of the plastic part, to prevent scald, and improves the adhesive melting effect.

Description

technical field

[0001] The invention relates to the field of hot-melt technology, and more specifically, relates to a protective material for making metal-plastic composite parts and a method for making metal-plastic composite parts. Background technique

[0002] Metal-plastic composite parts are parts that combine metal parts made of metal and plastic parts made of plastic. They usually appear in the field of electronic products, for example, the combination of metal casings and plastic panels of electronic products. At present, there are two commonly used bonding methods for metal parts and plastic parts of electronic products: dispensing and double-sided adhesive bonding. Dispensing is prone to glue overflow problems. For parts with very strict appearance requirements, for example: the metal shell of electronic products is a first-class surface, it is difficult to meet the requirements for appearance with dispensing, and the dispensing process has high requirements on the...
