Problems solved by technology

[0005] Chinese invention patent (CN201310363040) discloses a polyphenylene sulfide composite material and its preparation method. The composition is added by adding different types of polyamide and polyphenylene sulfide Ether forms an alloy, which improves the processing type of polyphenylene sulfide and reduces the cost. Although a composition with good comprehensive mechanical properties is obtained, it is found that the addition of polyamide will inevitably lead to an increase in the water absorption of the material, sacrificing the polyphenylene sulfide. Due to the advantages of low water absorption of sulfide, it takes longer to dry the material during the injection molding process, 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 relates to the field of polyphenylene sulfide resin processing and preparation, in particular to a glass fiber reinforced polyphenylene sulfide compound with high bonding strength with metal and a preparation method thereof. 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. [0003] Polyphenylene sulfide resin (PPS), also known as polyphenylene sulfide, PPS plastic is a light yellow, brown, high crystallinity, hard and brittle polymer. ...
