Embodiment 1

[0019] After the chlorinated high-cis-polybutadiene rubber (cis-1, 4-segment content 96%) glue with a chlorine content of 35% is evenly prepared in the glue tank, the dry glue content is measured, and the glue is metered by a metering pump , added to an oil-filled kettle and preheated to 40°C, then added 40 parts of chlorinated paraffin preheated to 30°C, stirred in an oil-filled kettle at 200r / min for 2 hours, then coagulated and dried. The chlorine content, Mooney viscosity and physical properties of the vulcanized rubber were measured before and after being filled with chlorinated paraffin, and its processing performance was investigated. The test conditions and test results are shown in Table 1.

Embodiment 2

[0025] Select chlorine content as 32% chlorinated high cis-polybutadiene rubber (cis 1, 96% content of 4 segments) glue, fill 30 parts of chlorinated paraffin, stir at a stirring speed of 100r / min for 1.5 hours, and the rest With embodiment 1.

Embodiment 3

[0027] Select the chlorinated high-cis-polybutadiene rubber (cis-1, 4-segment content 98%) glue with a chlorine content of 25%, fill with 20 parts of chlorinated paraffin, stir for 1 hour, and the rest are the same as in Example 1.

Abstract

The diolefin rubber chloride containing chloroparaffin consists of diolefin rubber chloride in 100 weight portions and chloroparaffin in 10-50 weight portions, and is prepared through chlorization process to prepare diolefin rubber chloride and filling chloroparaffin before the polymer rubber is solidified for mixing homogeneously. The present invention can raise the fire retarding effect, lower the Mooney coefficient and improve the machining performance of diolefin rubber chloride while maintaining the physical and mechanical performances of diolefin rubber chloride.

Description

technical field [0001] The invention belongs to the field of synthetic rubber industry, in particular to chlorine-containing chlorinated diene rubber and a preparation method thereof. Background technique [0002] Through the method of polymer chemical modification, on the basis of maintaining the performance of the original polymer to a large extent, the desired functional groups or elements can be introduced to improve its performance in some aspects, such as heat resistance, solvent resistance, and chemical resistance. Aging, ozone resistance, blendable or vulcanization properties. Among them, the chlorination modification of polymer is the most promising chemical modification method, which has been developed rapidly in recent years. Chlorination methods include chlorination with chlorine gas in an organic solvent, chlorination with an organic chlorinating agent, and chlorination with phase transfer catalysis. [0003] Usually diene polymers, i...
