Abstract

The invention discloses an unbreakable automobile meter framework material, which is prepared from, by weight, 60-80 parts of styrene- maleic anhydride copolymer, 30-40 parts of polystyrene, 10-20 parts of acrylonitrile- butadiene- styrol copolymer, 4-8 parts of crosslinking agent, 1.5-2.5 parts of titanate coupling agent, 45-50 parts of filling fortifier, 0.8-1.4 parts of 2, 2'-methylene bis(4-methyl-6-tertiary butyl phenol), 2-4 parts of distearyl thiodipropionate, 3-5 parts of tricresyl phosphite(n-dodecanol) ester. The filling fortifier is prepared from, by weight, 8-16 parts of iron-basedmontmorillonoid composite, 4-8 parts of glass fiber, 4-8 parts of hard kaoline, 3-7 parts of ground limestone, 4-6 parts of expanded graphite, and 8-16 parts of fly ash. The unbreakable automobile meter framework material has the advantages of extremely high tear resistance and impact resisting intensity, and extremely high shockproof performance; the meter framework is not easy to break.

Description

technical field [0001] The invention relates to the technical field of automobile instruments, in particular to a skeleton material of an automobile instrument which is not easily broken. Background technique [0002] For many years, the composite materials used by automobile companies all over the world for the framework of automobile dashboards are mainly glass fiber reinforced styrene-maleic anhydride copolymers. Glass fiber reinforced styrene-maleic anhydride copolymer (SMA resin) has good heat resistance, dimensional stability, processing fluidity and low cost and is widely used. However, due to its poor anti-vibration performance, on bumpy roads such as the suburbs, the frame of the car instrument is easy to break, which needs to be solved urgently. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a car instrument frame material that is not easy to break, which has high tear resi...
