Abstract

The making process of integrally pressed brake belt with blended fiber includes the following steps: 1. preparing blended fiber with several kinds of friction fiber material; 2. combing the blended fiber, adding metal net layer by layer and pressing integrally to form the belt blank; 3. soaking the belt blank in phenolic resin; 4. drying the soaked belt blank naturally; 5. heating to cure; and 6. polishing surface of the cured belt to produce brake belt product. The process has the advantages of high safety and saving in gasoline, and the product has raised heat resistance, wear resistance and stability and low cost.

Description

technical field [0001] The invention relates to the field of brake materials for mechanical equipment, in particular to a method for manufacturing a blended fiber integrally pressed brake band. Background technique [0002] Existing brake bands include blank bands and adhesive materials, which are roughly divided into two categories according to the manufacturing method, one is manufactured by pressing, and the other is manufactured by integral weaving. [0003] Pressing method to manufacture brake bands: including the multi-layer lamination processing method used in rubber-based cloth brake bands as shown in Figure 1 (a), and the rubber resin fiber stirring and pressing method used in rubber-based short-fiber brake bands as shown in Figure 1. 1(b). The brake bands manufactured by these two pressing methods all use natural rubber as the adhesive material. Since the rubber adhesive material will coke and decompose when the temperature reaches 150°C, the brake band will heat ...
