Problems solved by technology

The rubber used in the current hose generally adopts chloroprene rubber, nitrile rubber or styrene-butadiene rubber, etc. Although these rubbers have certain oil resistance properties, their aging resistance is not good. Some of the rubber hoses with very strict requirements use EPDM Rubber, but more expensive

Embodiment 1

[0025] Described xylan derivative comprises the following steps to make:

[0026] Step S21: Add xylan to dimethyl sulfoxide, stir magnetically for 30 minutes, add bromobutane and pyridine, heat up to 65°C, keep warm for 4 hours, add absolute ethanol while stirring after the reaction, and continue stirring until no precipitation produced, formed a suspension, stood still for 10h, filtered, extracted the filter cake for 48h, took out the solid, vacuum dried, and ground to obtain Intermediate 1, which controlled the concentration of xylan, dimethyl sulfoxide, bromobutane and pyridine. The dosage ratio is 1g: 50mL: 0.5g: 1.2mL;

[0027] Step S22: Add intermediate 1 to N,N-dimethylformamide, stir at a constant speed for 15 minutes, raise the temperature to 60°C, add triethylamine and cinnamoyl chloride solution, stir at a constant speed and react for 4 hours, after the reaction, add anhydrous Ethanol, stir at a constant speed until no precipitation occurs, let stand for 10h, filte...

Abstract

The invention relates to chlorinated polyethylene rubber compound and a preparation method thereof. The chlorinated polyethylene rubber compound comprises the following raw materials in parts by weight: 100-150 parts of chlorinated polyethylene rubber, 25-35 parts of a modifier, 2-5 parts of a vulcanizing agent, 1-2 parts of a vulcanizing aid, 15-25 parts of carbon black, 3-5 parts of a calcium-zinc stabilizer, 4-5 parts of a cross-linking agent, 8-10 parts of a plasticizer and 0.5-1.2 parts of stearic acid. The modifier is added for mixing, the modifier is a composite material of a carrier and a xylan derivative, the xylan derivative is dispersed into interlayers of the carrier, the modifier is prepared, the carrier hydrotalcite has an excellent ultraviolet physical shielding function, and the xylan derivative can absorb ultraviolet rays penetrating through hydrotalcite lamellas, so that the modifier has an ultraviolet absorption function and good ultraviolet reflection capability, and can significantly improve the anti-aging performance of the rubber compound as the modifier.

Description

technical field [0001] The invention belongs to the technical field of rubber production, and in particular relates to a chlorinated polyethylene compound rubber and a preparation method thereof. Background technique [0002] Rubber hoses, compared with hoses, focus on rubber hoses extruded from polymer chemical raw materials through vulcanization and other processes. The hose structure is usually divided into: inner rubber layer, outer rubber layer and skeleton layer (or middle layer). The inner rubber layer directly bears the abrasion and erosion of the conveying medium; the outer rubber layer protects the inner body of the rubber hose from damage and erosion of the external environment; the skeleton layer is the pressure-bearing layer of the rubber hose, giving the hose body strength and rigidity. The working pressure of the hose depends on the material and structure of the skeleton layer. [0003] Chlorinated polyethylene is a saturated polymer material with a white po...
