Obviously and it is readily appreciated that, wherein：
Fig. 1 is the method flow schematic diagram according to an embodiment of the invention for preparing dampening composition.
Specific implementation mode
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
In one aspect of the invention, the present invention proposes a kind of dampening composition.According to an embodiment of the invention, the resistance
Nylon 6 combination includes ABS resin, brombutyl, inorganic filler and compatilizer.Inventor's discovery, the ABS trees as matrix
Generally in 105 degree of glass transition temperature, nearby there are maximum damping factor, damped coefficients 1.1 for fat, but air-conditioning is practical makes
With temperature between 20-40 degree, make ABS resin damped coefficient between 0.1-0.2, therefore above-mentioned temperature range has been unable to reach
The damping of effect, and brombutyl has good damping at normal temperatures, dosing brombutyl can show
The damping for improving air-conditioning actual use temperature range is write, to reduce the generation of abnormal sound, however due to brombutyl
With the poor compatibility of ABS resin, it is necessary to so that brombutyl and ABS resin compatibility is improved using compatilizer, so that
Product is not stratified, and performance is more stable, while inorganic filler can significantly improve the rigidity, intensity and table of composition as additive
Face gloss, makes surface frame as appearance member, and sense organ more preferably, and can further increase damping factor.The damping combination of the composition as a result,

It does not limit, those skilled in the art can select according to actual needs, a specific example according to the present invention, compatilizer
It is connect to be selected from ABS grafted maleic anhydrides compound, SBS grafted maleic anhydrides compound, AS grafted maleic anhydrides compound and PS
At least one of branch maleic anhydride chemical combination object.Inventor has found that SBS, AS and PS are all styrenic polymer, with ABS
Resin have natural compatibility, using such styrenic polymer grafted maleic anhydride can play brombutyl and
The good compatible role of ABS resin, to improve the stability of product.
According to still a further embodiment, in order to improve the comprehensive performance of dampening composition, above-mentioned dampening composition
Further comprise at least one of antioxidant, lubricating oil and coupling agent.A specific embodiment according to the present invention, above-mentioned resistance
