Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] see figure 1 . The friction material production process of the rice-wheat straw brake pad ash-grinding brake pad in the preferred embodiment of the present invention includes steps:

[0014] S1: Incinerate rice and wheat straw in the environment of 350°C-400°C. After grinding for 2 hours, the brake pads are cooled and ground according to the mass parts. 7 parts of molybdenum disulfide: 1 part of aqua regia are mixed and sealed for 15 hours for later use. ;

[0015] S2: Add 10 kg of natural graphite and 5 kg of barite for every 100 kg of crushed rice and wheat straw, stir evenly, put it into a high-temperature pool for soaking, control the temperature at about 90 to 100°C, take it out and bake it for about 3 hours dry standby;

[0016] S3: The spare ground ash and the spare rice and wheat straw were mixed according to the mass ratio o...

Abstract

The invention provides a friction material production process for a ground rice and wheat straw brake pad, comprising the following steps: incinerating rice and wheat straw, grinding for 2 hours at 350-400 DEG C, cooling, mixing 7 parts of ground ash, 2 parts of molybdenum disulfide and 1 part of aqua regia, and sealing for 15 hours for later use; putting 10kg of natural graphite and 5kg of barite in each 100kg of ground rice and wheat straw, uniformly stirring, putting in a high temperature tank for soaking, controlling the temperature at about 90-100 DEG C, taking out after about 3 hours, and baking for later use; and mixing the standby ground ash and the standby rice and wheat straw according to the mass fraction of 1:1 for 15 minutes, and then carrying out carbonization, neutralizing treatment, activation and enhanced treatment. The friction material production process has the advantage of reasonable utilization of waste.

Description

technical field [0001] The invention relates to the production field of friction materials for automobile brake pads, in particular to a friction material production process for brake pads made of rice straw and ash. Background technique [0002] During the production process of current brake pads, the dust generated by grooving, chamfering, and size grinding has plagued enterprises for a long time. According to the annual production of 100 million sets of brake pads, each set of 1 kg of friction material will produce 0.12 kg of ash, and 100 million sets of brake pads will produce 120,000 kg of ash, which will cause great pollution to the environment. [0003] Therefore, how to design a technology for rationally utilizing grinding ash is a problem that the industry needs to solve urgently. Contents of the invention [0004] In order to solve the above-mentioned existing technical problems, the present invention provides a friction material production process of rice-wheat...
