According to the present invention, the rubber vibration absorption sleeve material has characteristics of high hardness and deformation resistance, the surface friction coefficient of the product is low, and the matching property with the inner rod is good after assembly.
Description
Technical field
The present invention relates to shock-absorbing sleeve technical field, relate in particular to a kind of rubber shock-absorbing cover material.
Background technology
The vibroshock of automobile is also referred to as " suspension ", by spring and vibroshock, jointly formed, vibroshock is not for supporting the weight of vehicle body, but concussion while being used for suppressing rebounding after spring shock-absorbing and absorb the energy of road shocks, spring works to relax impact, " macro-energy one-shot " become to " little energy repeatedly impacts ", and vibroshock is exactly progressively " little energy repeatedly impacts " to be reduced, vibroshock is equipped with in suspension system inside at most of automobiles, and follow that vibroshock exists also just have a rubber shock-absorbing sleeve.Function and the vibroshock of shock-absorbing sleeve are similar, and it can play subsidiary function to vibroshock, help to promote the effect of damping, how to prepare a kind of hardness high, not yielding, and good with the conformability of interior bar after assembling, the rubber shock-absorbing cover material that friction noise is little becomes the current technical issues that need to address.
Summary of the invention
The present invention proposes a kind of rubber shock-absorbing cover material, hardness is high, not yielding, and product surface frictional coefficient is lower, and good with the conformability of interior bar after assembling, friction noise is little.
A kind of rubber shock-absorbing cover material that the present invention proposes, its raw materials by weight comprises:
In embodiment, the weight percent of paracril NBR can be 40, 41, 43, 44, 45, 46, 48, 50%, the weight percent of silicon-dioxide can be 20, 21, 24, 25, 27, 28, 29, 30%, talcous weight percent can be 0, 1, 2, 3, 4, 5%, the weight percent of sulphur can be 1, 2, 2.5, 3, 4%, the weight percent of dioctyl terephthalate DOTP can be 0, 2, 3, 4.5, 5, 6, 8, 10%, the weight percent of carbon black can be 15, 17, 17.5, 18, 18.5, 20, 21, 22%, the weight percent of higher fatty acid can be 1, 1.5, 2, 2.5, 3, 4%.
Preferably, described silicon-dioxide by quartzy, phosphorus is quartzy, cristobalite or form without quartzy one or more of fixed row.
Preferably, in described talcum powder, magnesian content is 31-33%, and the content of silicon oxide is 62-64%, and the content of water is 4-5%, and its Mohs' hardness is 1.21-1.35.
