experiment example 1

[0040] Using the same test conditions to test the coefficient of friction of X1 prepared in Comparative Example and the compositions of Examples 1-6 within 600°C, coefficient of thermal fading, density, compressive strain, impact strength, weight loss after the AK-MASTER test, etc. For details, see Table 2.

[0041] The X1 that table 2 comparative example makes and the performance effect data of the composition of embodiment 1-6

[0042]

[0043]

[0044] As can be seen from Table 2, the performance of the low-cost low-metal copper-free composition for automobile brake pads provided by the present invention is obviously better than that of X1, which may be due to the fact that each component in the composition of the present invention is produced under a specific ratio. In order to realize the effect of synergy, it is found through comparative data that the thermal recession coefficient in the X1 formula is only 0.25, which is due to the fact that the rubber-based formula ...

Abstract

The invention discloses a low-cost low-metal copper-free composition for an automobile brake pad, application and a preparation method thereof, and relates to the technical field of automobile brake pad preparation. The low-cost low-metal copper-free composition for the automobile brake pad is made of steel fibers, and the mode that inorganic adhesives and inorganic fibers are mixed with heat-resisting organic fibers is further matched for use. According to the low-cost low-metal copper-free composition for the automobile brake pad, the low-content steel fibers are adopted to be matched with the nonmetal-type inorganic fibers and the heat-resisting organic fibers for use; and moreover, raw materials like copper fibers causing environmental pollution are not contained in the formula, the hybrid fiber friction material is excellent in property, all the fibers make the best of the advantages of others, material strength is guaranteed and meanwhile the frictional wear performance of the product can be ensured.

Description

technical field [0001] The invention relates to the technical field of preparation of automobile brake pads, in particular to a low-cost, low-metal, copper-free composition for automobile brake pads. Background technique [0002] With the rapid development of automobile industry and transportation at home and abroad, on the one hand, the high growth rate has provided a market for friction material products; on the other hand, the increase in vehicle speed has put forward more stringent requirements for the performance of friction materials. The first is the requirement of environmental protection; the second is to have a good friction coefficient and wear resistance, with a certain heat resistance and mechanical strength; the last is to meet the market requirements, to ensure the performance and develop lower cost brake pad formula more and more become a trend. [0003] Automobile brake pads are an important part to ensure the safety of automobiles. However, with the popul...
