Problems solved by technology

[0007] (3) For products with high dimensional accuracy requirements (especially for multi-cavity molds), this process is lacking
[0008] (4) The disadvantage of compression molding is that the mold manufacturing is complicated, the investment is large, and due to the limitation of the press, it is impossible to manufacture larger products
[0009] (5) The surface wear resistance of the phenolic resin bushing is not good

Abstract

The invention discloses a phenolic resin shaft sleeve. The phenolic resin shaft sleeve comprises the following components by mass percent: 30-45% of fiber mono-filaments, 25-40% of thermosetting phenolic resin, 5-15% of hydroxymethyl cellulose and 15-30% of carbonate, wherein carbonate is a calcium carbonate andmagnesium carbonate mixture with the grain size of 400 meshes or above. A manufacturingprocess of the phenolic resin shaft sleeve comprises the following steps: (1) mixing; (2) drying; (3) impregnation; (4) stoving; (5) reeling; (6) curing formation; and (7) processing. The provided phenolic resin shaft sleeve has favorable universality, is suitable for forming of various complicated products, and does not need a mold, and the manufactured phenolic resin shaft sleeve has good surface abrasive resistance and high temperature resistance.

Description

technical field [0001] The invention relates to the field of shaft sleeves, in particular to a phenolic resin shaft sleeve and a manufacturing method thereof. Background technique [0002] Phenolic resin bushings can maintain their structural integrity and dimensional stability even at very high temperatures, so they are widely used in some high-temperature fields, such as refractory materials, friction materials, adhesives and foundry industries . [0003] The patent application document with the application number 201611188868.4 discloses a new type of shaft sleeve and its preparation method. It mainly uses special plastic substrates to bond and compound these carbon fibers with X-Y directions by molding; thus obtaining excellent performance. Specialty composites. [0004] The defective of this kind preparation process is: [0005] (1) It is not suitable for compression molding of complex products with depressions, side slopes or small holes. [0006] (2) In the manufa...
