Embodiment
See Fig. 1, the present invention relates to a kind of corrosion-resistant braking string, comprise internal lining pipe 2 and two winding springs 3 of surrounding layer 1, two side by side parallel settings, the length of two internal lining pipes 2 is equal, braking string body 4 is provided with in described internal lining pipe 2, two are wound around the outer wall that spring 3 is wrapped in internal lining pipe 2 respectively, and surrounding layer 1 is coated on two and is wound around outside spring 3.
See Fig. 2-3, described braking string body 4 comprises carbon fiber heart yearn group 4.1 and the outer field resin layer 4.2 of internal layer, described carbon fiber heart yearn group 4.1 is made up of multi-beam carbon-fiber heart yearn, 1000 ~ 200000 carbon fibers are comprised in every a branch of carbon fiber core, the diameter of every root carbon fiber is 5 ~ 15 microns, described resin layer is formed by the material mixture ratio of following mass ratio: epoxy resin 25 ~ 40%, modified paint phenolphthalein resin 25 ~ 40%, titanium nano particle 5 ~ 10%, color stuffing 10 ~ 15%, curing agent 10 ~ 15%, solvent 15 ~ 20%, described curing agent is capsule curing agent, capsule curing agent comprises core and wall material, the particle diameter of described capsule curing agent is 10 μm, described core is ethylenediamine, described wall material is polymethylmethacrylate, color stuffing is French chalk, plumbago, aluminium powder and pigment, the mass ratio of described French chalk, plumbago, aluminium powder and pigment is 20:5:3:10, described pigment is any one or two kinds of titanium dioxide, zine oxide, and described solvent is one or both of ethanol and acetic acid, and the mass ratio of described ethanol and acetic acid is 3:1.
