Description

Technical Field

[0001] The invention relates to the field of friction brake materials, in particular to a method for preparing a wear-resistant noise-reducing material suitable for a two-wheeled vehicle brake pad. Background Art

[0002] Two-wheeled vehicle braking systems (such as motorcycles and electric vehicles) widely use non-asbestos organic friction materials, semi-metallic materials, or ceramic-reinforced friction materials. Although these materials have certain braking performance, they are prone to the following problems in actual use:

[0003] Prominent brake noise: Especially during low-speed coasting, the initial braking phase, or wet conditions, a high-frequency "squealing" noise, also known as brake squeal, is easily generated between the friction pad and the brake disc. Prior art research has proposed reducing brake noise through coatings or surface treatments. For example, patent US11655864B2 reduces friction-induced vibration noise by applying a graphite-containing thermosetting resin coating to the friction pad surface.

[0004] Poor wear resistance: Two-wheeled vehicles often experience frequent starts and stops, and high braking frequency, which can lead to rapid wear of friction materials. While some improved materials improve wear resistance, this often sacrifices friction coefficient stability and noise control.

[0005] Unstable friction performance: Particularly under high-temperature or thermal decay conditions, the friction coefficient of some metal-based friction materials decreases significantly, making them unsuitable for high-speed braking. For example, patent US11635120B2 states that using Ni or Ni-Fe as a metal matrix, incorporating oxide or nitride particles and solid lubricants, can improve high-temperature stability and friction performance, but lacks systematic optimization for noise control.

[0006] In the prior art, some have proposed using organic fillers (such as cashew nut shell powder and rubber particles) as friction modifiers to improve chemical stability, reduce noise, and enhance wear resistance. For example, Nisshinbo Industries' patent proposes that by adding 2–20 vol% cashew nut shell powder, 10–25 vol% rubber particles, and a small amount of solid lubricant, the braking static friction coefficient can be increased and noise can be suppressed, but it is not specifically designed for the vibration characteristics of two-wheeled vehicles. Another Japanese patent, JP2014251547, also points out that the use of straight novolak-type phenolic resin can effectively suppress low-frequency noise, and its lower elastic modulus helps to reduce the stick-slip phenomenon.

[0007] In summary, although the existing two-wheeled vehicle friction material technology has made progress in some aspects, it still has the following shortcomings:

[0008] There is little suppression of high-frequency brake noise generated by two-wheeled vehicles at low speeds; existing patents mostly focus on passenger cars or heavy-duty vehicles; there is a lack of systematic technical solutions that can coordinate the design of hard phase reinforcement, solid lubricants and organic fillers to balance wear resistance, friction stability and noise reduction performance; in particular, there is a lack of methods for preparing friction materials that introduce fiber or microporous structures to improve damping and reduce noise based on the vibration characteristics of two-wheeled vehicles. Summary of the Invention

[0009] Based on the above-mentioned technical status, the present invention proposes a preparation method of a wear-resistant and noise-reducing material suitable for two-wheeled vehicle brake pads. By rationally selecting metal matrix powder, hard phase reinforcement material, solid lubricant, organic filler and microfiber, they work together to improve friction performance, wear resistance and noise control, and have better performance in working stability and adaptability to extreme conditions.

[0010] The technical solution is as follows:

[0011] A method for preparing a wear-resistant and noise-reducing material suitable for a two-wheeled vehicle brake pad comprises the following steps:

[0012] 1) Ingredients stage, by mass

[0013] Ni-Fe alloy powder: 40-60 parts;

[0014] Hard phase reinforcement particles: 18-35 parts;

[0015] Solid lubricant: 4-12 parts;

[0016] Microfiber reinforcement: 4-10 parts;

[0017] Organic binder: 10-20 parts;

[0018] Lanthanum (III)-indazole-cashew nut shell oil phenolic resin additive: 0.5-2 parts;

[0019] Filler / damping agent: the rest up to a total of 145 parts;

[0020] 2) Mixing process

[0021] All ingredients are mixed evenly in a ball mill or V-type mixer for 10-30 minutes;

[0022] 3) Press molding

[0023] Press the mixture onto the metal backing plate with a certain pressure and hold it for 30-60 seconds;

[0024] 4) Hot pressing sintering / curing

[0025] If hot pressing sintering is used: set the temperature to 200-300℃ and keep warm for 1-3 hours;

[0026] If compression curing is used: temperature 130-160°C, pressure 20-50 MPa, hold pressure for 2-8 minutes

[0027] 5) Post-processing stage

[0028] Post-cure at set temperature for 1-2 hours to perfect the bonding network.

[0029] Preferably, the hard phase reinforcement particles are a mixture of ZrO2, TiO2, and mullite, with ZrO2: 6-14 parts, TiO2: 6-14 parts, and mullite: 6-14 parts.

[0030] Preferably, the solid lubricant comprises 15-35wt% of MoS2, 5-15wt% of BN, 5-15wt% of FeS, and the rest is graphite.

[0031] Preferably, the microfiber reinforcement material is selected from aramid fibers or microcellulose fibers.

[0032] Preferably, the organic binder is selected from phenolic resin, epoxy-modified phenolic resin, polyvinyl acetal-modified phenolic resin or cashew nut shell oil-modified phenolic resin.

[0033] Preferably, the filler / damping agent is selected from rubber powder, graphite powder, and talc powder.

[0034] Preferably, the preparation method of the lanthanum (III)-indazole-cashew nut shell oil phenolic resin additive is:

[0035] According to parts by mass, 20-30 parts of cashew nut shell liquid-modified phenolic resin and 6-10 parts of 5-carboxyindazole are added to 30-40 parts of toluene, 1-3 parts of zinc chloride are added as a catalyst, and an acylation reaction is carried out at a temperature of 80-90°C. After a period of reaction, the system is cooled, 0.03-0.08 parts of La(NO3)3·6H2O are added, and the reaction is continued for 2-5 hours. After post-treatment, a lanthanum (III)-indazole-cashew nut shell oil phenolic resin additive is obtained.

[0036] Preferably, the rotation speed in the mixing process is 60-150 rpm.

[0037] Preferably, the pressure during the compression molding is 100-200 MPa.

[0038] Preferably, the curing temperature is 300-350°C.

[0039] Reaction mechanism: 5-carboxyindazole is grafted onto the molecular chain of cashew nut shell oil phenolic resin through acylation reaction, which enhances the rigidity and thermal stability of the resin; La 3+It coordinates with indazole and other groups to form a stable chemical structure, which can form a uniform transfer film during the friction process and improve the friction performance.

[0041] The composite friction material produced by the preparation method described herein, through hard phase reinforcement, lubricant ratio, and microfiber-introduced microporous damping structure, not only improves friction coefficient and wear resistance, but also effectively suppresses braking noise. It is particularly suitable for braking applications on high- and low-speed two-wheeled vehicles. DETAILED DESCRIPTION
