Nitrile recycled rubber is processed from waste nitrile rubber and its products as raw materials, with excellent oil resistance, and can be used alone or in combination with nitrile rubber to produce oil-resistant rubber products and reduce raw material costs. Nitrile rubber and neoprene are ideal raw materials for the production of oil-resistant rubber boots, and can nitrile recycled rubber be used in the production of oil-resistant rubber boots as a substitute product for high-priced nitrile rubber? How much nitrile recycled rubber is better to use in oil-resistant rubber boots?
1. Can nitrile recycled rubber produce oil-resistant rubber boots?
Nitrile recycled rubber has excellent oil resistance, good elasticity, high plasticity, and good compatibility with nitrile rubber and neoprene, which can replace some nitrile original rubber to produce oil-resistant rubber boots, reducing raw material costs and production energy consumption. Oil-resistant rubber boots are special protective equipment used to protect the feet from oil substances, rationally use nitrile recycled rubber, oil-resistant rubber boots can maintain stable physical properties in oil media such as mineral oil, animal and vegetable oil, lubricating oil for a long time, and provide safety protection for the feet.
2. Selection skills and application methods of nitrile recycled rubber for oil-resistant rubber boots
When using nitrile recycled rubber to replace part of the original nitrile rubber to produce oil-resistant rubber boots, it is recommended to choose a nitrile recycled rubber E5LYY98 with medium and high acrylonitrile content, Mooney viscosity among 45-65, high fineness, and no impurities. In actual production, nitrile recycled rubber can be used alone or in combination with nitrile rubber and neoprene in an appropriate proportion to produce oil-resistant rubber boots, and if necessary, it can also be blended with nitrile rubber and PVC to prepare oil-resistant rubber and plastic soles, so as to improve the comprehensive performance of the finished product and reduce more costs.
3. Nitrile recycled rubber and original rubber are used together to produce oil-resistant rubber boot formula
(1) Nitrile rubber/neoprene/nitrile recycled rubber is used to produce oil-resistant rubber boot upper formula
30 parts of nitrile rubber, 50 parts of neoprene, 20 parts of nitrile recycled rubber, 5 parts of zinc oxide, 2.5 parts of stearic acid, 1 part of anti-aging agent A, 0.5 parts of anti-aging agent D, 50 parts of carbon black N330, 10 parts of light calcium carbonate, 30 parts of dibutyl phthalate, 3 parts of magnesium oxide, 0.1 part of accelerator D, 0.2 parts of accelerator TMTD; Total 202.3 copies.
(2) Nitrile rubber/nitrile recycled rubber is used to produce oil-resistant rubber boot sole formula
70 parts of nitrile rubber, 30 parts of nitrile recycled rubber, 5 parts of zinc oxide, 1 part of stearic acid, 1 part of anti-aging agent A, 1 part of anti-aging agent D, 25 parts of carbon black N330, 75 parts of terracotta, 10 parts of coumarone resin, 25 parts of dibutyl phthalate, 0.5 parts of accelerator M, 0.2 parts of accelerator D, 1 part of accelerator DM, 0.2 parts of accelerator TMTD, 2 parts of sulfur; Total 246.9 copies.
Compared with nitrile rubber, nitrile recycled rubber has better plasticity and fluidity, less expansion and contraction during processing of unvulcanized rubber, less heat generation in processing, etc., replacing some nitrile rubber to produce oil-resistant rubber boots can not only reduce the cost of raw materials, but also improve the performance of rubber processing technology and reduce production energy consumption. In the later stage, we will continue to share with you the formula design and production process points of nitrile recycled rubber production oil-resistant rubber boots.
