Embodiment Construction

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below, obviously, the described embodiments are only some of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0017] A manufacturing process of a clutch face, comprising the following steps:

[0018] S1. Preparation of Cashew Nut Shell Oil Modified Phenolic Resin Adhesive: Add phenol, formaldehyde, cashew nut shell oil and catalyst into the reaction kettle, stir and heat up to 100°C, react at constant temperature for 4 hours, vacuumize and dehydrate, and raise the temperature of the material to 160°C When discharging, the solid obtained after cooling is cashew nut shell oil modified phenolic resin;

[0019] S2. Selection of rein...

Abstract

The invention discloses a manufacturing process for a clutch surface patch. The preparation process comprises the following steps of S1, preparation of a cashew nut shell oil modified phenol resin adhesive; S2, selection of a reinforcing material, a filler and a friction performance adjustment agent; S3, material mixing, hot pressing and forming and heat treatment; S4, grinding and polishing and inspection and packaging. Cashew nut shell oil serves as a modifier for phenol resin, the flexibility of the phenol resin can be effectively adjusted, the resin can have certain plastic deformation capacity in the frictional heating process, and noise is further lowered while the friction coefficient is increased. The cashew nut shell oil is utilized to modify the phenol resin, the heat resistanceand tenacity of the material can be obvious improved, the friction performance is excellent, a carbonized film formed on the surface of the material in the friction process is soft, has tenacity and is not prone to falling, the composition and heating states of the surface of the friction material are uniform, and stable friction performance is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of automobile clutch faces, and in particular relates to a manufacturing process of clutch faces. Background technique [0002] Modern brake materials can be classified according to material type: resin-based brake materials, powder metallurgy brake materials, carbon / carbon composite brake materials and ceramic-based brake materials. Resin-based brake materials are widely used in equipment braking due to their structural designability, excellent friction and wear properties, certain heat resistance and mechanical strength, and relatively low cost. Resin-based brake materials are mainly composed of resin matrix, reinforcing fibers, friction modifiers and fillers mixed and hot-pressed. The resin matrix binds all components into a whole and plays the role of transmitting and balancing loads. It is the main component of brake materials. It is an important component; but it is also the component with the worst c...
