Problems solved by technology

[0002] The bicycle brake system includes accessories such as brake handles, brake lines, and brake calipers. The brake system of the prior art is usually provided with a front and a rear brake line and two corresponding brake handles and two brake calipers. The brake line is prone to breakage after being used for a period of time, causing brake failure and high potential safety hazards. In order to solve the above technical problems, it is necessary to use a two-line brake system with two front brake lines and two rear brake lines. The two brake lines of this brake system The length of the two front brake cables must be the same to ensure that the two brake cable bodies are evenly stressed during braking. However, the two independent brake cable bodies cannot guarantee the same length, and there are certain difficulties in assembly.
[0003] The existing brake line body is composed of an outer rubber hollow tube and an inner steel wire, its strength is not high enough, its chemical corrosion resistance is poor, its weather resistance is not good, and its production cost is relatively high
[0004] The friction and supporting force between the existing brake line liner and the outer cladding are not enough, and the inner liner and the outer cladding tend to slide relative to each other, which will cause the brake to not be tight and affect the use effect of the braking system; the existing The end of the outer cladding layer of the brake line has no outer sleeve, so the end joint of the brake line is easy to wear, which affects the use effect of the brake system
[0005] The end of the existing brake line body is a hook used to fix the handle. After a long time of use, the hook will be deformed, which will cause the brake line to be disengaged from the handle, thereby causing brake failure and accidents
[0006] The outer cladding of the existing brake line is exposed to the environment for a long time. If it encounters corrosion or scorching heat, it will affect the normal use of the brake line, and in serious cases, there will be safety hazards

Embodiment 1

[0040] Example 1, put 35 parts of polyvinyl alcohol and 23 parts of potassium sorbate into the reactor and mix them. The mixing time is 1.5 hours, the mixing temperature is 40 degrees, and the mixing speed is 90 r / min. After mixing, 16 parts of dispersant are added , continue to stir for 20 minutes, then add 8 parts of talcum powder, 7 parts of resole phenolic resin and 4 parts of microencapsulated red phosphorus. Can.

Embodiment 2

[0041] Example 2, put 37 parts of polyvinyl alcohol and 25 parts of potassium sorbate into the reactor and mix them. The mixing time is 1.5 hours, the mixing temperature is 40 degrees, and the mixing speed is 90 r / min. After mixing, add 14 parts of dispersant , continue to stir for 20 minutes, then add 13 parts of talcum powder, 7 parts of resole phenolic resin and 4 parts of microencapsulated red phosphorus. Can.

Embodiment 3

[0042] Example 3, 33 parts of polyvinyl alcohol and 21 parts of potassium sorbate were mixed in the reactor, the mixing time was 1.5 hours, the mixing temperature was 40 degrees, the mixing speed was 90 r / min, and 18 parts of dispersant were added after the mixing , continue to stir for 20 minutes, then add 14 parts of talcum powder, 9 parts of resole phenolic resin and 5 parts of microencapsulated red phosphorus, the mixing temperature is 50 degrees, the mixing speed is 110r / min, until the mixing is uniform, naturally cool to room temperature Can.

[0043] The brake line body 4 of the present invention is molded at one time. In the process of preparing the brake line body, the head of the extruder passes through a bundle of continuous carbon fibers, and the molten resin layer 4.2 coming out of the extruder is tightly coated. The brake line body 4 is made on the carbon fiber core wire group 4.1.

[0044] The diameter of the carbon fiber core wire group 4.1 can be controlled b...

Abstract

The invention relates to a high-strength anti-corrosion fireproof brake cable including an outer wrapping layer (1), two parallel lining pipes (2) which are arranged side by side, and two metal wire sets (3); each brake cable body (4) comprises a carbon fiber core wire set (4.1) on the inner layer and a resin layer (4.2) on the outer layer; one end of an outer casing pipe (5) is arranged on the outer wrapping layer (1), the other end of the outer casing pipe (5) extends outwards along the axial direction of the outer wrapping layer (1) and is arranged on the brake cable bodies (4); an annular belt (6) is arranged at the end part of each brake cable body (4), and the surface of the outer wrapping layer (1) is provided with a anti-corrosion fireproof coating layer. The high-strength anti-corrosion fireproof brake cable has the advantages of simple molding, light mass, chemical corrosion resistance, good weather resistance, low production cost, and safe driving, and allows the brake cable bodies to be uniform in stress; the surface of the outer wrapping layer is provided with the anti-corrosion fireproof coating layer, so that the brake cable is effectively protected, and the normal use of the brake cable is ensured.
