[0003] CN102558863A discloses a low-dielectric polyphenylene sulfide composite material and a preparation method thereof. The composition realizes low dielectric properties by adding polytetrafluoroethylene (hereinafter referred to as PTFE) with low dielectric properties, although the obtained dielectric The polyphenylene sulfide composite material with a property of 2.8, but the melting point of polyphenylene sulfide is 280 ° C, the melting point of PTFE is 330 ° C, and PTFE is relatively difficult to process, and the molding shrinkage rate is very large (3.0%); and PTFE is a non-polar Non-toxic polymers, poor adhesion to metals
CN103525088A discloses a polyphenylene sulfide composite material and its preparation method. The composition forms an alloy by adding different types of polyamide and polyphenylene sulfide, which improves the processing type of polyphenylene sulfide and reduces the cost, although it has obtained A composition with good comprehensive mechanical properties, but research has found that the addition of polyamide will inevitably lead to an increase in the water absorption of the material, sacrificing the advantages of low water absorption of polyphenylene sulfide, and it will take longer to use during the injection molding process. For dry materials, and the dielectric properties, weather resistance and other related properties of the composite material have not been effectively improved

Description

technical field [0001] The invention belongs to the field of composite materials, and relates to a method for bonding and fixing metal parts, a polysulfone composite material for bonding and fixing metals, a preparation method and an application. Background technique [0002] In recent years, with the diversification of people's demand for the appearance of electronic products, the appearance quality of electronic products is constantly changing. The single metal or plastic casing of electronic products can no longer meet the diversified market needs. Combined electronic product casings have become people's new favorite. At present, some of the more popular electronic product bodies on the market are the products of the combination technology of aluminum alloy surface treatment and resin polymer. However, electronic products have higher and higher requirements on materials, especially in terms of signal penetration. The dielectric constant and loss factor of materials need ...
