preparation example Construction

[0025] A kind of preparation method of the multifunctional rubber vulcanizate containing modified graphene oxide of the present invention comprises the following steps:

[0026] Step 1: Preparation of polyvinylpyrrolidone-modified graphene oxide: Add graphite oxide to the aqueous solution, ultrasonically disperse, ultrasonic time 0.5-1h, power 100-300W, add polyvinylpyrrolidone, continue ultrasonic stirring, ultrasonic time 0.5 -1h, power 100-300W, obtain polyvinylpyrrolidone modified graphene oxide aqueous solution;

[0027] Step 2: mixing and stirring the polyvinylpyrrolidone-modified graphene oxide aqueous solution prepared in step 1 with rubber latex, adding a gelling agent, washing and drying the gel to obtain a rubber mixture containing polyvinylpyrrolidone-modified graphene oxide;

[0028] Step 3: After mixing the rubber mixture containing polyvinylpyrrolidone modified graphene oxide obtained in step 2 with zinc oxide, stearic acid, anti-aging agent, accelerator and vul...

Embodiment 1

[0040] Disperse 1 part of graphite oxide in the aqueous solution, 100W ultrasonic 1h, add 1 part of polyvinylpyrrolidone, power 100W ultrasonic stirring 1h, obtain polyvinylpyrrolidone modified graphene oxide aqueous solution, wherein the size of polyvinylpyrrolidone modified graphene oxide is as follows figure 2; Add it dropwise to natural rubber latex, mix and stir, and add a gel agent, wash and dry the gel to obtain a rubber mixture containing 1 part of modified graphene oxide; further mix it with 3 parts of zinc oxide, 1 part of Stearic acid, 2 parts of RD, 0.5 parts of DM and 3 parts of sulfur are mixed on the open mill, parked, and the vulcanization time is measured with a vulcanizer, and then the rubber vulcanizate is obtained with a flat vulcanizer. Among them, the XRD diffraction of vulcanized rubber is as follows figure 1 shown. The detailed properties of the vulcanizate are shown in Table 1.

Embodiment 2

[0042] Repeat the method of Example 1 according to the specified content of each component, but adopt 2 parts of polyvinylpyrrolidone-modified graphene oxide in the formula. The detailed properties of the vulcanizate are shown in Table 1.

Abstract

The invention discloses multifunctional vulcanized rubber containing polyvinylpyrrolidone-modified graphene oxide and a preparation method of the multifunctional vulcanized rubber. The multifunctional vulcanized rubber comprises the following components in parts by mass: 100 parts of rubber matrix, 1-4 parts of polyvinylpyrrolidone-modified graphene oxide, 2-5 parts of an anti-aging agent, 3-10 parts of zinc oxide, 1-3 parts of stearic acid, 0.5-1 part of a vulcanizing accelerator and 1-3 parts of a vulcanizing agent. The multifunctional vulcanized rubber prepared by the method has a plurality of functions, such as a mechanical function, a heat-conducting function and a solvent-resistant function.

Description

technical field [0001] The invention belongs to rubber-like polymer composite materials and a preparation method thereof, in particular to a multifunctional rubber vulcanizate containing polyvinylpyrrolidone-modified graphene oxide and having excellent mechanical properties, heat conduction and solvent resistance, and a preparation method thereof. Background technique [0002] Multifunctional rubber vulcanizates, that is, rubber vulcanizates with excellent mechanical properties, thermal conductivity and solvent resistance, are one of the research hotspots in the rubber industry. Graphene oxide, a two-dimensional material, has the characteristics of high mechanical strength (63GPa), high modulus, large specific surface area and good barrier properties, and is easy to prepare and low cost. It has received extensive attention as a new carbon-based material. However, since the surface of graphene oxide contains a large number of oxygen-containing functional groups, graphene oxid...
