Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] see see figure 1 . figure 1 It is a schematic block diagram of the production process flow of a friction material made of wheat straw in a preferred embodiment of the present invention.

[0015] A production process for making friction material from wheat straw according to an embodiment of the present invention includes steps:

[0016] S1: providing wheat straw, removing moldy and rotten parts in the wheat straw, removing soil and impurities therein to generate clean wheat straw;

[0017] S2: crushing the clean wheat straw, the length of which is 0.1-0.2 cm after crushing, and then performing incomplete carbonization in an oxygen-poor furnace to generate incomplete carbonized wheat straw grains;

[0018] In this step, the wheat straw is crushed, and the crushed length is about 0.1-0.2 cm. The crushed rice and wheat straw must not be ...

Abstract

The invention provides a production process of preparing friction material with wheat straw. The production process includes the steps of: providing wheat straw and removing the mildewed and rotten parts as well as mud and impurities in the wheat straw to obtain clean wheat straw; crushing the clean wheat straw into the length of 0.1-0.2 cm, and incompletely carbonizing the clean wheat straw in an oxygen deficient furnace to obtain incompletely carbonized wheat straw granules; activating the incompletely carbonized wheat straw granules and removing impurities in a winnowing manner, and foaming and grinding the granules to obtain the friction material. The friction material has good use performances and good compression resistance performance.

Description

technical field [0001] The invention relates to the technical production field of friction materials, in particular to a production process for making friction materials from wheat straw. Background technique [0002] The existing brake pad friction material has little elasticity and poor compression resistance when used. [0003] Therefore, how to design a friction material production process with large deformation during use and good compression resistance is an urgent issue in the industry. Contents of the invention [0004] In order to solve the above-mentioned existing technical problems, the production process of using wheat straw to make friction material provided by the present invention has the advantages of high elasticity in the use process and good compression resistance. [0005] The invention provides a production process for making friction material from wheat straw, which comprises the steps of: [0006] providing wheat straw, removing moldy and rotten pa...
