Problems solved by technology

[0004] The purpose of the present invention is to solve the disadvantages of polluting environment, endangering human health, poor friction performance and rough production process of the existing brake belt, the fibers used are simple, the textile performance is poor, and modern advanced powerful weaving machines cannot be used to weave blank belts. And the use of resin is unreasonable, and the product density is low, the strength is small, it is easy to break, it is not wear-resistant, and it cannot meet the requirements of modern mechanical equipment.

Abstract

This invention relates to a brake strap of blended fibrage, which belongs to braking material field of mechanical apparatus. The present brake strap comprises the following defects: environmental contamination, harm to human's health, bad frictional behavior, rough manufacturing technique, bad textile performance, low product density, small strong force, fissility, easy attrition, no adaptability to modernization equipment. In order to settle these problems, the invention provides a brake strap of blended fibrage with multilayer, and its characters are following: including stock straps and adhesive material, many core-spun single yarn of blended fibrage, which contains a wire, twisted into twine and braided into said stock straps, selecting thermoplastic phenolic resin as adhesive material, osmosizing fully into braided brake strap with multilayer. The invention comprises the following merits: good textile performance, various fibre mixing fully, homogeneous wire distribution, dense textile texture, high product density, burliness, strong force, good flexible performance, logical friction coefficient, good abradability and heat-durability, flexibility and diversification, satisfying the need of power transmission, deceleration and braking of various mechanical equipment, safe reliability, no environmental contamination and harm to human's health in the process of production and application.

Description

technical field [0001] The invention relates to a blended fiber braided brake band, which belongs to the field of mechanical equipment brake materials. Background technique [0002] The base belt of the existing brake band is woven from asbestos fiber yarn or other spinnable fiber and glass long fiber twisted yarn. Because asbestos fiber is harmful to human health and pollutes the environment during the processing and production process, many Countries have banned the use (including China). And asbestos fiber is a kind of natural mineral fiber, its chemical composition and physical properties can not be changed, so the brake band produced by this fiber, the friction performance is difficult to adjust, and the application occasion is limited. Poor reliability and short service life. Similarly, other spinnable fibers and glass long fiber twisted yarns have simple and rough processing techniques, single fibers, poor spinnability, and uneven distribution of metal wires. Theref...
