Problems solved by technology

[0002] At present, the dry resin (adhesive) and other powdery and short fiber or debris-like materials are used as raw materials in the friction product formula produced by the dry hot pressing process. Due to the inherent defects of the dry process, It will cause a lot of dust to pollute the environment in the process of blending wool, and it will also damage the health of workers. It is required to strengthen the automation, continuity and sealing of the operation process, but these are difficult in the actual production process. It is very well controlled, so it requires some innovation in the formulation process
[0003] Secondly, due to the limitation of formula cost, the compatibility of organic raw materials and inorganic raw materials is not good, which affects the performance of finished products after hot pressing

Abstract

The invention discloses a silane coupling agent modified friction material and a friction plate made of the friction material. The friction material comprises components in a frictional material formula and a processed silane coupling agent. A method for preparing the friction material comprises steps as follows: raw materials are prepared according to the friction material formula, the components of the friction material are uniformly mixed through a mixing process, and the processed silane coupling agent is sprayed into mixing equipment through the mixing process. The silane coupling agent modified friction material and the friction plate made of the friction material have the benefits as follows: the problem about compatibility of raw materials in a friction product is solved, then one friction product is provided, the friction product improves impact strength and inner shearing strength while the friction coefficient and performance are not damaged under the same condition, the wearing is reduced, and the friction plate made of the friction material can be applied to the harsh working condition.
