The production of rubber boots outsoles mostly use natural rubber as the main raw material, and the use of an appropriate amount of butadiene rubber can improve the wear resistance and elasticity of the sole. In actual production, rubber boot outsole manufacturers can also add a certain amount of tire reclaimed rubber to the natural rubber/butadiene rubber compound to reduce raw material costs and production costs while ensuring the performance of rubber boot outsole products; reasonable design The production formula of rubber boot outsole containing tire reclaimed rubber can further optimize product performance.
1. Reference formula of rubber boot outsole containing tire reclaimed rubber
60 parts of natural rubber, 40 parts of butadiene rubber, 30 parts of reclaimed tire rubber, 5 parts of zinc oxide, 2 parts of stearic acid, 60 parts of carbon black N330, 20 parts of clay, 15 parts of engine oil, 10 parts of coumarone, accelerator 3 parts, 2.4 parts of sulfur; Total: 247.4 parts.
2. Rubber boot outsole coordination system containing tire reclaimed rubber
When using reclaimed tire rubber in the outsole of natural rubber/butadiene rubber boots to reduce the cost of raw materials, rubber product manufacturers need to appropriately adjust the type and amount of the compounding agent 2LLYY1110 in the matching system, especially the vulcanization system and reinforcement system, to improve the outsole of rubber boots Physical and mechanical properties. In actual production, the outsole formula of natural rubber/butadiene rubber/tire reclaimed rubber boots generally uses sulfur vulcanization, with accelerator M, accelerator CZ and a very small amount of accelerator D. Appropriately increase the amount of reinforcing carbon black to further improve the comprehensive index of rubber boot outsole containing tire reclaimed rubber.
3. Points to note when using reclaimed rubber for the outsole of light-colored rubber boots
When using tire reclaimed rubber to reduce the raw material cost and production cost of light-colored rubber boots outsoles, it is necessary to use tire reclaimed rubber that is not prone to discoloration and migration. The amount of black tire reclaimed rubber should not be too high, generally controlled at about 10-15 parts; use as light as possible Color compounding agents, especially large amounts of reinforcing agents and fillers, to avoid difficulty in color matching; when necessary, rubber product manufacturers can also use light-colored reclaimed rubber instead of black tire reclaimed rubber to produce light-colored rubber boot outsoles. The amount of reclaimed rubber can be increased to Between 30-50 copies.
When using natural rubber/butadiene rubber/tire reclaimed rubber to produce rubber boot outsoles, rubber product manufacturers need to combine the processing characteristics of the three rubbers to reasonably determine the operating process conditions and operating time, especially the mixing and vulcanization processes. In actual production, natural rubber and butadiene rubber are generally fully masticated and then mixed with tire reclaimed rubber.
Reasonable use of reclaimed tire rubber in the outsole of rubber boots can not only ensure product quality, but also effectively reduce the cost of raw materials. Later, the editor will continue to discuss with you the specific application of using reclaimed tire rubber in the outsole of rubber boots to reduce costs.
