Abstract

The invention relates to a fastener used by a railway track, which comprises a track pitch baffle, a baffle base and an insulation track pitch block. The technical proposal is that: prepreg of thermoplastic resin composite is taken as the base material and is cut to be shaped; after being preheated, pulled, pressed, solidified and shaped, the material is made into insulation components of the track. The prepreg of thermoplastic resin composite refers to prepreg composite obtained by combining the thermoplastic resin and nemaline reinforced material; the thickness of the prepreg of thermoplastic resin composite is ranging between 0.1 mm-0.6mm, and the proportion of the reinforced material inside the prepreg of thermoplastic resin composite is 20-40 percent of that of the thermoplastic resin. The invention is characterized by great strength and modulus, good size stability, lasting static resistance, small friction coefficient, wear resistance, long service life, etc.

Description

technical field [0001] The invention relates to a fastener for railway track, in particular to a track insulation component processed by using thermoplastic resin matrix composite material for the fastener of railway track. Background technique [0002] In the track insulation components, the traditional technology mostly uses metal sheets and insulating layers to form composite insulation parts. Due to the large differences in the linear expansion coefficient, compressive strength and impact strength of metal materials and plastic insulating materials, it is reflected in the application In the middle, there will be poor weather resistance of the insulating parts, no wear resistance, and unsatisfactory service life. Chinese patent CN94106253.8 (railway rail composite insulating part) discloses a kind of multi-layer metal sheet, adhesive and glass fiber cloth bonding, and is equipped with a plastic insulating sheath, which can improve the service life of the insulating part. ...
