Problems solved by technology

Although the thermal ablation process can improve the recession to a certain extent, it cannot solve this problem, and the ablation is easy to cause other problems, such as: the shear force is reduced, easy to peel off; the uniformity of ablation; and Product consistency, etc.

Embodiment Construction

[0013]

[0014] According to above formula, sample is processed according to the production technology of prior art, and test: test result:

[0015] Ordinary metal-less formula has a decay rate of over 40% when performing the decay procedure, and the high-speed performance is also very poor, less than 0.25, while the metal-less formula A with sodium titanate whiskers has a decay rate of 12%, and the 160 km At high speed per hour, the coefficient of friction is 0.33. The metal-less formula B with sodium titanate whiskers has a decay rate of 10%, and the friction coefficient is 0.35 at a high speed of 160 km / h.

[0016] It can be seen from the above data that due to the use of sodium titanate whiskers, the performance of the metal-less formula brake pads has been greatly improved, and its decline rate has reached the goal of less than 15%, and the high-speed performance has also been very good. The improvement, the friction coefficient is greater than 0.32.

Abstract

The invention provides a preparing formula of low metallic brake pad by utilizing sodium titanate whisker, which comprises (by weight) 5%-15% of adhesive, 15%-25% of reinforced fiber, 10%-20% of abrasive, 8%-15% of lubricant, 10%-20% of modifier and 30%-50% of filler. By the aid of the brake pad prepared according to the formula, the air porosity can be effectively improved and the high-temperature resistance of materials can be enhanced, thus the decomposition rate of organic materials at a high temperature can be reduced, the escaping speed of gas on friction surfaces in brake fading can be lowered simultaneously, and the fading rate and the changing rate of frictional coefficient at high speed can be reduced to below 15%.

Description

technical field [0001] The invention relates to a production formula of a brake pad, in particular to a formula for producing a brake pad by using sodium titanate whiskers. Background technique [0002] In addition to binders, reinforcing fibers, abrasives, lubricants, and fillers, the basic composition of metal-less brake pad materials also includes a very important material—friction performance regulator. The specific processing technology is as follows: mixing—hot pressing - Grinding - Painting - Installation accessories - Printing - Packaging. [0003] High-temperature fading performance and high-speed stability are two crucial performance indicators of brake pads, which directly affect the braking safety and comfort of the product. Although the thermal ablation process can improve the recession to a certain extent, it cannot solve this problem, and the ablation is easy to cause other problems, such as: shear force drop, easy to peel off; ablation uniformity; and Produ...
