Embodiment 1

[0023] Grind the wheat straw with a ball mill first, then take 1000g of the crushed fiber, add 150g of water, 50g of glycerin, 50g of sorbitol, and 50g of polyvinyl alcohol, mix evenly with an internal mixer, dry and pulverize to prepare a particle size of Relatively small thermoplastic fiber ultrafine powder. Add 0.5% coupling agent, mix well and set aside.

[0024] Take 10g of the superfine fiber composite powder and mix it with 100g of natural rubber at 70°C, add 1.0g of vulcanizing agent and 1.0g of vulcanization accelerator at the same time; Under vulcanization for 15min.

Embodiment 2

[0026] First grind the rice husk with a ball mill, then take 1000g of the crushed fiber, add 150g of water, 50g of glycerin, 50g of sorbitol, and 50g of polyvinyl alcohol, mix evenly with an internal mixer, dry and grind to prepare a particle size of Relatively small thermoplastic fiber ultrafine powder. Add 0.5% coupling agent, mix well and set aside.

[0027] Take 10 g of the superfine fiber composite powder, and knead together with 100 g of natural rubber at 80° C., and add 1.0 g of vulcanizing agent and 1.0 g of vulcanization accelerator at the same time. The mixing process takes about 20 minutes, and the prepared rubber is vulcanized at 170° C. for 15 minutes.

Abstract

The invention belongs to the technical filed of synthetic rubber and particularly relates to a fiber filling agent used for rubber and a preparation method thereof; the fiber filling agent comprises anatural fiber, a coupling agent and a modifying agent and is prepared by adopting the following process: the natural fiber raw material is crushed into more than 20 meshes of fiber powder, and then the coupling agent and the modified materials are added to the fiber powder and evenly mixed with the same in a banbury mixer; and the process is simple, the processing process of the rubber is not changed, and the invention can be used for replacing the partial or the total carbon black and white carbon black type filling agent, reduces the manufacturing cost of the rubber and saves the natural mineral resources.

Description

Technical field: [0001] The invention belongs to the technical field of synthetic rubber, in particular to a fiber filler for rubber. Background technique: [0002] Because of its excellent oil resistance, alkali resistance, impact resistance, seawater corrosion resistance, ultraviolet light and high-energy radiation resistance, low air permeability; at the same time, it has good adhesion, low temperature flexibility, electrical insulation and good Construction performance; therefore, it is widely used in aviation, petroleum, chemical industry, shipbuilding, automobile, construction, electromechanical, instrumentation, water conservancy, electric power, railway and other fields. [0003] In rubber manufacturing, in order to obtain rubber with better performance, carbon black and white carbon black fillers are commonly used. Carbon black and white carbon black are mineral filler materials. These mineral filler materials are made from ore after a certain The production proces...
