Abstract

The invention provides a composite material special for an automobile engine oil pan and a preparation method thereof. The composite material contains nylon, alkali-free short glass fiber, a mineral filler, a modifier and an aid. The nylon is nylon 66, high-temperature nylon or a mixture thereof; the mineral filler is one or a mixture of more of mica, wollastonite, talcpowder, calcium carbonate, barium sulfate and kaolin; the modifier is selected from ABS, PE, PC, PPS, PPO, PBT and PET; and the aid contains a temperature resistant ageing agent, a lubricating agent, a nucleating agent and a coloring agent. The composite material special for the automobile engine oil pan has the advantages of light weight, high design freedom degree, low cost, low rejection rate, and shock and noise resistance. The durability of the material meets the requirement on the service life of ten years (or of accumulatively running 1000,000 km), and the material passes the using test under a cold environment at the low temperature of 30 DEG C below zero, and reaches an international leading level.

Description

technical field [0001] The invention relates to the field of automobile engine oil pans, in particular to a special composite material for automobile engine oil pans and a preparation method thereof. Background technique [0002] The oil pan of the vehicle engine is installed at the bottom of the engine, which is used to store oil and seal the crankcase to prevent impurities from entering, collect and store lubricating oil flowing back from the friction surfaces of the engine, dissipate part of the heat, and prevent lubricating oil from oxidizing, etc. [0003] The development process of automobile engine oil pan materials and corresponding processes is: cast iron or cast aluminum parts - single-layer thin steel stamping parts - die-cast aluminum alloy parts - (metal / plastic / metal) sandwich composite parts - SMC thermosetting Plastic Molded Parts - (Nylon) Thermoplastic Injection Molded Parts. [0004] The oil pan made of aluminum alloy die-casting has good quality indicato...
