Abstract

The invention relates to a friction plate, in particular to a wet brake friction plate and a manufacturing method thereof. The wet brake friction plate is manufacturing from the following raw materials: 35-38 parts of cotton pulp, 8-10 parts of carbon fiber, 13-15 parts of aramid fiber, 20-25 parts of graphite, 6-8 parts of sepiolite, 6-8 parts of friction powder, 10-15 parts of iron oxide red, 5-8 parts of iron oxide yellow, 4-5 parts of latex, 8-10 parts of feldspar, 0.5-1 part of raw alkali and 0.06-0.08 part of sulfur. The manufacturing method comprises the following steps of: material proportioning -> pulping -> papermaking -> paper drying -> paper cutting -> gum dipping -> secondary paper drying -> paper curing -> chip plate treatment -> pasting -> friction plate curing -> subsequent friction plate processing -> cleaning and packaging. According to the wet brake friction plate and the manufacturing method thereof, the friction coefficient is increased, and the service life is prolonged.

Description

technical field [0001] The invention relates to a friction plate, in particular to a wet brake friction plate and a preparation method thereof. Background technique [0002] In agricultural machinery, the wet brakes used have extremely high requirements on the performance of the friction plates. Since the annual working hours of agricultural machinery are relatively short, and the harvesting task must be completed in a limited period of time, the quality requirements for the friction plates are extremely high. The following problems are found in the use of traditional friction plates: 1. The effective friction area of ​​the friction plate is too small; 2. The friction coefficient is small and the wear is relatively large. Only one harvesting period can be completed, or even one harvesting period cannot be completed. It affects the agricultural harvest as scheduled, and at the same time affects the quality of agricultural products. Contents of the invention [0003] The in...
