Embodiment Construction

[0028] A kind of rice-wheat straw activated carbon powder toughened granular friction material is produced according to the following method:

[0029] Step 1. Cleaning of rice and wheat straw materials: Collect newly harvested or one-year rice and wheat straw, remove moldy and rotten rice and wheat straw, and clean the soil and impurities on the straw;

[0030] Step 2. Drying: Expose or dry the cleaned rice and wheat straw; when drying, the drying temperature is 45°C-55°C, and the drying time is 1-1.5 hours; The water content is 9%-13%;

[0031] Step 3, crushing: crushing the dried rice and wheat straw into rice and wheat straw powder with a length of 0.1-0.2 cm, and storing in a dry place;

[0032] Step 4, proportioning and stirring: 100 parts of rice straw powder mixed with 1 part of vermiculite and stirred evenly;

[0033] Step 5, forming a mandrel under high pressure: pressing the mixture of rice and wheat straw powder and vermiculite into a mandrel; the mandrel has a le...

Abstract

The invention discloses a rice-wheat straw activated carbon powder toughening particle friction material and a preparation method thereof. The rice-wheat straw activated carbon powder toughening particle friction material comprises the following components: 48 parts of a rice-wheat straw activated carbon powder toughening particle, 5 parts of tire powder, 2 parts of talc, 4 parts of graphite, 1 part of pyrite powder, 2 parts of phenolic modified resin, 37 parts of natural rubber, 0.5 part of an anti-aging agent and 0.5 part of sulfur. By the toughening particle friction material prepared by the preparation method, the toughness and the friction coefficient of friction materials such as brake blocks can be increased, the production cost is decreased, the toughening particle friction material is environmentally friendly and free of pollution and simultaneously the use channels of rice-wheat straws can be broadened.

Description

technical field [0001] The invention relates to a rice-wheat straw activated carbon powder toughened granular friction material and a preparation method thereof, which belong to the field of chemical industry. Background technique [0002] The annual output of crop straw in our country reaches more than 700 million tons, but most of these resources are burned except for a small amount of feed, which not only causes a huge waste of resources but also causes serious environmental pollution. Rice and wheat straw contains a large amount of carbon sources and has high utilization value, such as materials that can replace phosphorus flake graphite through special processes, and composite fibers. For example, our company discloses a method of making friction material for brake pads from rice and wheat straw in patent CN 103820078 A. The formula is as follows: 15% toughening fiber, 16% modified resin, 14% friction agent, sulfur + tin Powder 9%, carbon black 1.6%, zinc oxide 2.5%, b...
