The tread adhesive of the bicycle tire needs to be continuously frictioned with the road surface during riding and is subjected to bending, stretching and other forces, which requires the rubber to have good wear resistance, flex resistance, etc. Sufficient tensile strength, tear strength, and appropriate elasticity ensure riding safety and comfort. Bicycle black tread adhesive is generally made of natural rubber or natural rubber, styrene-butadiene rubber, and butadiene rubber and processed with glue as raw materials; The appropriate use of recycled rubber can effectively reduce the cost of raw materials.
1. Bicycle black tire tread adhesive is commonly used in recycled rubber varieties
(1) Tire recycled rubber
The main components are natural rubber, general synthetic rubber and carbon black, which are compatible with natural rubber, styrene-butadiene rubber or butadiene rubber, and can replace some raw rubber to produce black bicycle tire tread adhesive and reduce raw material costs.
(2) Black latex recycled glue
Black latex recycled rubber is generally processed from variegated waste natural rubber and its products as raw materials, retaining the basic performance characteristics of natural rubber, good elasticity, high strength, and can replace natural rubber in whole or in part E5LYY43 produce black bicycle tires and reduce costs. From the price point of view, black latex recycled rubber with the same index is lower and more cost-effective than white natural rubber recycled rubber.
(3) Styrene-butadiene recycled rubber
Styrene-butadiene recycled rubber is generally processed from hoses and tapes with good elasticity, with tear resistance, wear resistance and anti-aging, high plasticity, easy mixing, low heat generation, good low temperature flexibility and other characteristics, replacing part of styrene-butadiene rubber or using natural rubber and general synthetic rubber to produce bicycle tire tread adhesive can reduce the production cost by 15%-20%.
(4) Cs-buting recycled rubber
Clay butadiene recycled rubber is mostly processed from waste raw materials such as highly cold-resistant tapes, rubber rings, diaphragms, etc., with cold resistance, wear resistance and other performance characteristics, and can be used with natural rubber and butadiene rubber to produce bicycle tire tread adhesive to reduce raw material costs.

45 parts of natural rubber, 20 parts of butadiene rubber, 35 parts of tire recycled rubber, 2.5 parts of zinc oxide, 2.5 parts of stearic acid, 0.4 parts of paraffin, 0.8 parts of anti-aging agent D, 0.6 parts of anti-aging agent AW, 0.3 parts of anti-aging agent 4010NA, 9 parts of carbon black N660, 50 parts of ultra-fine calcium carbonate, 40 parts of activated calcium carbonate, 1 part of diethylene glycol, 13 parts of naphthenic oil, 7 parts of coumarone resin, 1 part of accelerator DM, 0.25 parts of accelerator D, 1.65 parts of sulfur; Total 230 copies.
When using recycled rubber to reduce the production cost of bicycle black tire tread adhesive, rubber product manufacturers must choose the appropriate recycled rubber variety according to actual needs, reasonably determine the proportion of recycled rubber mixing, some products can completely use recycled rubber, especially black natural latex recycled rubber and high-strength tire recycled rubber, and continue to share with you the key points of recycled rubber production bicycle tire tread compound formula design in the later stage.
