Problems solved by technology

[0003] The materials used for automotive water chamber components are required to be resistant to ethylene glycol solution, other chemical corrosive agents, and aqueous solutions above 100°C. At the same time, stress cracking is not allowed at the junction during the assembly process. Ordinary nylon materials have been difficult to meet the above requirements.
[0004] Most of the alcoholysis-resistant materials in the prior art achieve alcoholysis-resistant performance by adding an alcoholysis-resistant agent or an alcoholysis-resistant agent. Although it improves the alcoholysis-resistant properties of the material, the overall performance of the material decreases instead; At the same time, due to the high processing temperature, the anti-alcoholysis agent or anti-alcoholysis agent may decompose, resulting in a decrease in the overall corrosion resistance of the material, affecting production quality and efficiency

Abstract

The invention discloses a processing method of a hydrolysis and alcoholysis resistant PPE (polyphenylene ether) / glass fiber masterbatch. The processing method comprises the following steps: combining ultrasonic waves with mechanical vibration before and after and carrying out dip pretreatment on glass fibers by utilizing graphene, a silane coupling agent and a PPE melt, thus processing the hydrolysis and alcoholysis resistant PPE / glass fiber masterbatch. The processing method has the excellent effects that composite materials using the PPE / glass fiber masterbatch have excellent alcoholysis resistance which meets the TL-VW774 test requirements; specimen surfaces are good, are unchanged and do not crack; and not only is the problem that alcoholysis resistant agents need to be added to meet the requirement of alcoholysis resistance in the prior art solved but also the problem that the mechanical properties of base materials are obviously reduced after PPE is added in the prior art is solved.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a processing method of hydroalcolysis-resistant PPE / glass fiber masterbatch. Background technique [0002] With the rapid development of the automobile industry, replacing steel with plastic has become the trend and direction of the development of automobile materials. Glass fiber reinforced nylon materials are widely used in water chamber parts of automobiles, such as thermostats, for their excellent heat resistance and mechanical properties. Shells, water tank joints, etc. These parts not only require the material to have excellent mechanical properties, but also require the material to have good hydrolysis resistance and alcoholysis resistance, and can be used for a long time in hot water and antifreeze ethylene glycol mixed solution without performance degradation. [0003] The materials used for automotive water chamber parts are required to be resistant to ethylene glycol ...
