preparation example Construction

[0044] The present invention also provides a method for preparing the elastic composite, which is characterized in that it is prepared by a liquid-phase mixing and dispersing process, and the steps include: 1) making a modified white carbon black grinding slurry or carbon black in a non-polar organic solvent Grinding slurry; 2) Dispersing and mixing filler slurry or filler and rubber glue under high-energy shearing in proportion; 3) Dry removing the solvent from the uniformly dispersed composite slurry glue under dynamic conditions; 4) Removing The complex of solvents is sheared, kneaded and dried to obtain a product.

[0045] The solvent used in the filler slurry is non-polar organic solvents such as aliphatic hydrocarbons, alicyclic hydrocarbons, and aromatic hydrocarbons.

[0046] The solvent used in the rubber solution is non-polar organic solvents such as aliphatic hydrocarbons, alicyclic hydrocarbons, and aromatic hydrocarbons.

[0047] In step 1), if the filler is whit...

Embodiment 1

[0060] According to the preparation method of modified silica disclosed in patent application number 201410724713.2, a modified silica slurry with a silica aggregate particle size of 100nm-5μm was obtained, and the solid content was 5%wt.

[0061] In the high-energy disperser, 13.5kg of the above-mentioned modified white carbon black slurry is mixed with 6.8kg of concentration of 20%wt solution-polymerized styrene-butadiene rubber glue, wherein the ratio of the two solid contents is, rubber: white carbon black= 100:50. The high-energy disperser disperses the white carbon black evenly among the rubber molecules while grinding it to obtain a composite mixed liquid.

[0062] The composite mixed liquid is sent to the devolatilization extruder for solvent removal, and the temperature range of the eight blocks on the devolatilization extruder is set to 40-100°C, and the screw speed is 100 rpm. The compound mixed liquid is obtained through the extruder, and the volatile matter conte...

Embodiment 2

[0065] According to the preparation method of modified silica disclosed in patent application number 201410724713.2, a modified silica slurry with a silica aggregate particle size of 100nm-5μm was obtained, and the solid content was 10%wt.

[0066] In a high-energy disperser, mix 9kg of the above-mentioned modified silica slurry with 22.5kg of 5%wt solution-polymerized styrene-butadiene rubber glue, wherein the ratio of the two solid contents is, rubber: silica=100 :80. The high-energy disperser disperses the white carbon black evenly among the rubber molecules while grinding it to obtain a composite mixed liquid.

[0067] The composite mixed liquid is sent to the devolatilization extruder for solvent removal, and the temperature range of the eight blocks on the devolatilization extruder is set to 40-100°C, and the screw speed is 150 rpm. The compound mixed liquid is obtained through the extruder, and the volatile matter content is less than 1%.

Abstract

The invention discloses a preparation method of an elastic complex, comprising the following steps: (1) preparing modified white carbon black grinding slurry or carbon black grinding slurry in a nonpolar organic solvent, marking the modified white carbon black grinding slurry or carbon black grinding slurry as filler slurry, and marking the modified white carbon black or carbon black as a filler; (2) dispersing and mixing the filler slurry or filler and a rubber glue solution proportionally under high-energy shearing to form a complex slurry glue solution; (3) removing the solvent from the uniformly dispersed and mixed complex slurry glue solution by a dry method under a dynamic state; and (4) shearing, kneading and drying the solvent removed complex to obtain the product; wherein the nonpolar organic solvent in the step (1) and the solvent used by the rubber glue solution in the step (2) are aliphatic hydrocarbon, alicyclic hydrocarbon or aromatic series nonpolar organic solvents.

Description

technical field [0001] The invention relates to the preparation of an elastic composite body, in particular to a method for preparing elastic composite materials used for high-performance tires. Background technique [0002] For nearly half a century, solution-polymerized synthetic rubber has developed into an irreplaceable important raw material for tires. Especially solution-polymerized styrene-butadiene rubber, with its ever-changing new structure, provides various viscoelastic properties required by tires, and makes silica an important reinforcing filler for reinforcing rubber. Tires made with silica and solution rubber have lower rolling resistance and higher wet skid resistance than tires made with carbon black and emulsion rubber. Therefore, solution polymerized synthetic rubber and silica have become important basic materials for high-performance tires. [0003] The braking performance of tires on wet roads, on the one hand, comes from the grip of the tires on the ...
