Abstract
The invention relates to a compound mullite automotive brake pad. Mullite in the automotive brake pad is processed to reach the nanometer level; an additive is added, so that the automotive brake pad has the performance of heat resistance, light weight, low heat accumulation, low thermal conductivity, wear resistance and high sound absorption. The compound mullite automotive brake pad is mainly applied to braking in automotive braking devices and the recycling of discarded materials.
Description
The present invention relates to a kind of mullite automobile brake sheet, its mullite reaches nanometer by processing, and makes it possess heat resistanceheat resistant, in light weight, low accumulation of heat, low heat conductivity, the good performance of sound absorption properties by adding additive.The brake device for car brake block that adopts this automobile brake sheet to make, in its braking process, present braking steadily, no impact, noise free, progressive sense is arranged, no dust.
At present, automobile brake sheet in use all is up to state standards though all state every performances such as friction factor, wear rate, hardness, impact toughness.But it is second-rate, even the new car that has is on five kilometers the road of travelling, brake block several very big holes that just rubbed out.Therefore there is certain hidden danger in the brake block in the automobile braking device in using at present, and can not carries out the secondary recovery utilization.
Purpose of the present invention provides a kind of compound automobile brake sheet of being made up of nano mullite, realize steadily, no impact, noise free, no dust, wear and tear little, finish automobile brake safely and reliably.And can realize the utilization again after material is discarded.
The objective of the invention is to be achieved by the following scheme: make mullite reach nanometer → the be blended into additive material → stirring homogenize → moulding of other compositions.
Owing to adopted above-mentioned design proposal, can make nanometer mullite automobile brake sheet possess heat resistanceheat resistant, in light weight, low accumulation of heat, low heat conductivity, the good performance of sound absorption properties, realize steadily, no impact, noise free, no dust, the little braking of finishing brake device for car safely and reliably of wearing and tearing, and realize utilization again after material is discarded.
Below in conjunction with the prescription and the accessible data thereof of nano mullite automobile brake sheet, the present invention will be further described.
The formula table of nano mullite automobile brake sheet
| Sequence number | 1 | 2 | 3 | 4 | 5 |
| Material | Nano mullite | Modified resin | Increase the agent that rubs | The friction stabilizer | The antifriction agent |
| Ratio % | 13 | 14 | 16 | 10.5 | 2.5 |
| Sequence number | ?6 | ?7 | ?8 | ?9 | ?10 | ?11 |
| Material | Additive 1 | Additive 2 | Additive 3 | Additive 4 | Additive 5 | Additive 6 |
| Ratio % | ?3 | ?3 | ?10.5 | ?9.5 | ?16 | ?4 |
By above-mentioned prescription with adopt certain technology to make the braking device of different performance, to above-mentioned sample carried out friction, wear test detects, test result meets the requirement of NBS and relevant industry standard.Result such as following table:
Claims (3)
1. compound mullite automobile brake sheet, mullite in its material reaches nanometer by processing, and make it possess heat resistanceheat resistant, in light weight, low accumulation of heat, low heat conductivity, wear-resistant, the good performance of sound absorption properties by adding additive, can realize the utilization again after discarded of braking function in the brake device for car and material.
2. the braking function in the realization brake device for car according to claim 1.It is characterized in that: the prescription that this automobile brake sheet uses nanometer mullite material and other composition materials to form.
3. the utilization again after material according to claim 1 is discarded, it is characterized in that: the constituent in this automobile brake sheet can be recycled.
