Raw paper of high-performance environment-friendly paper based friction material and manufacturing method of friction plate

Abstract

The invention discloses raw paper of a high-performance environment-friendly paper based friction material and a manufacturing method of a friction plate. The high-performance environment-friendly paper based friction material is characterized by comprising the following components in percentage by weight: a substrate comprises 7-15% of carbon fiber, 5-10% of chopped aramid fiber, 5-10% of aramidpulp and 9-30% of bamboo fiber pulp; a friction agent comprises 10-20% of kieselguhr and 8-12% of cashew nut shell powder; a frictional property regulator adopts 2-4% of rubber particles, 5-10% of calcium carbonate and 10-15% of flake graphite; and a forming adhesive comprises 1-2% of fluororubber, 3-15% of silicone resin and 3-15% of phenolic resin. The invention fully forms the materials of thefriction material into a whole by changing the traditional impregnation process, effectively improves the physical and mechanical properties of the friction plate, improves the friction factors, regulates the dynamic and static friction ratio factors, and reduces the abrasion ratio of the friction plate.

Description

technical field

[0001] The invention relates to a paper-based friction material base paper and a method for making the friction plate, in particular to a high-performance paper-based friction material that can work in brakes and clutches and a method for making friction plates using the material. Background technique

[0002] Paper-based friction material refers to the use of wet papermaking technology to produce homogeneous multi-material base paper, and then to prepare friction sheets by die-cutting, dipping, and lamination hot-pressing methods. It is widely used in construction machinery, agricultural machinery, mining machinery, and heavy-duty vehicles. It is used to transmit torque, decelerate and brake in the clutch and brake systems of machinery, cars and ships.

[0003] In China, dry-process powder metallurgy molding is widely used to manufacture friction plates for friction materials in the past. Its advantage is one-time molding, powder friction raw materials can ...
