Embodiment Construction

[0018] A kind of preparation method of the fiber of surface coating starch composite hydrogenated nitrile butadiene rubber, comprises the following steps:

[0019] (1) Add 45 parts by weight of nitrile latex dropwise to 2.5 parts by weight of hydrazine hydrate while stirring, then add 15 parts by weight of water, stir for 35 minutes until evenly mixed, then add 8 parts by weight of boric acid and hydrogen peroxide mixture dropwise, Adjust the reaction temperature to 50°C. After the dropwise addition, raise the temperature to 90°C and continue the reaction for 2.5 hours. Then add 40 parts by weight of oxidized starch solution to the torque rheometer for 2 hours. Keep the temperature at 70°C and add 0.2 weight 1 part of stearic acid, 0.2 parts by weight of anti-aging agent, 0.3 parts by weight of accelerator M, and 3.5 parts by weight of sulfur were stirred evenly, the temperature was raised to 80 ° C, 2.5 parts by weight of plasticizer was added and stirred for 1.5 hours, and th...

Abstract

The invention discloses a preparing method of fiber with the surface coated with starch composite hydrogenated butadiene-acrylonitrile rubber. The method includes the steps of adding oxidized starch for compositing after hydrogenated modification of butadiene-acrylonitrile latex through a hydrazine hydrate method, mixing the oxidized starch with other aids to prepare oxidized starch composite hydrogenated butadiene-acrylonitrile rubber, conducting oxidization modification after activating carbon fiber, and conducting drying, vulcanizing and blending after infiltrating the carbon fiber and glass fiber with latex. The mechanical strength and use performance of the prepared fiber with the surface coated with the starch composite hydrogenated butadiene-acrylonitrile rubber are greatly improved, and the method is easy and convenient to operate, high in production efficiency and small in material loss.

Description

technical field [0001] The invention belongs to the field of composite materials, and in particular relates to a method for preparing fibers coated with starch and compounded with hydrogenated nitrile rubber. Background technique [0002] Due to the existence of carbon-carbon double bonds, nitrile rubber has poor ozone aging resistance and chemical resistance. Compared with nitrile rubber, hydrogenated nitrile rubber has better performance than nitrile rubber. Hydrogenation modification is one of the important directions of rubber modification. Hydrogenation modification improves the oxygen resistance, heat resistance and aging resistance of polymers, prolongs the life of polymers, and expands the application fields of synthetic rubber materials. Unsaturated rubber can generally be modified by hydrogenation. The hydrogenation of rubber is mainly the addition reaction between hydrogen and the unsaturated double bond on the rubber molecular chain. The C=C double bond in the m...
