Abstract

The invention discloses asbestos-yarn-free impregnated resin for an automobile clutch. The asbestos-yarn-free impregnated resin is prepared from, by weight, 10 parts of phenolic resin, 10 parts of curing agent and 50 parts of organic solvent. A preparation technology of the asbestos-yarn-free impregnated resin for the automobile clutch comprises the following steps of raw material pretreatment, raw material mixing and solution preparation. Free phenol in the phenolic resin is reduced through a distillation still at first, then, the phenolic resin is mixed with the curing agent, the phenolic resin, the curing agent and the organic solvent are beaten through a stirring machine into slurry, the steps are simple, the performance of the phenolic resin is effectively improved, and the quality ofthe whole product is improved. Compared with traditional asbestos-yarn-free impregnated resin for the automobile clutch, the technology is simple, and the adhesion effect is better.

Description

technical field [0001] The invention belongs to the field of adhesives for clutch friction plates, and more specifically relates to a non-asbestos thread impregnated resin for automobile clutches. Simultaneously, the invention also relates to a preparation process of asbestos-free thread impregnated resin for automobile clutch. Background technique [0002] The friction part is the main component of the friction clutch, and the physical and mechanical properties of the working surface material directly affect the working performance of the clutch. The main requirements for the material are: the friction coefficient is large and stable, and the dynamic friction coefficient should be as close as possible to the static friction coefficient; the strength is high, it can withstand impact, and it is not easy to break and peel off at high speed; The deformation is small; it should not stick when left standing for a long time. In addition, long service life, easy processing and lo...
