Problems solved by technology

[0003] Due to the relatively harsh working environment of construction machinery and equipment, the hydraulic oil pipe is not only affected by the oil pressure generated by the hydraulic oil, but also affected by external factors such as temperature, humidity and oil pollution. If things go on like this, the outer rubber hose of the hydraulic oil pipe is prone to mildew. It affects the performance of the outer rubber hose, and also affects the overall performance and life of the hydraulic oil pipe

Embodiment 1

[0016] The specific preparation steps of the outer rubber hose for hydraulic oil pipes with excellent anti-mold performance mentioned in the present invention are as follows:

[0017] a) Material selection and preparation, the main components of the outer rubber hose and their percentage ratios are: 40% of raw silicone rubber powder, 11% of polyethylene resin, 11% of anti-mildew filler, 32% of white carbon black, and the rest are related auxiliary materials. The white carbon black is fumed silica; the active agent in the auxiliary agent is zinc oxide, the lubricant is microcrystalline paraffin, the accelerator is accelerator BZ and accelerator CZ, the anti-aging agent is anti-aging agent DNP, and the plasticizer is selected Stearic acid, vulcanizing agent selects vulcanizing agent DTBP;

[0018] The antifungal filler is zeolite particles treated with antifungal agent. The antifungal agent is prepared from 8-hydroxyquinoline copper and glacial acetic acid. The mixing ratio of t...

Abstract

The invention provides a preparation method of an excellent-mildew resistance outer rubber pipe for a hydraulic oil pipe. The preparation method comprises a, material selection and preparation, b, rubber mixing, c, mixing, d, extrusion sulfuration and e, after-treatment. The preparation method has reasonable and simple processes and a moderate cost. The excellent-mildew resistance outer rubber pipe has high strength, heat resistance, stable corrosion resistance and unique mildew resistance. The preparation method effectively prolongs a hydraulic oil pipe service life and widens a hydraulic oil pipe application scope.

Description

technical field [0001] The invention relates to a method for preparing an outer rubber hose for hydraulic oil pipes, in particular to a method for preparing an outer rubber hose for hydraulic oil pipes with excellent anti-mold performance, and belongs to the technical field of hydraulic accessories. Background technique [0002] Hydraulic equipment is widely used in excavators, loaders, road rollers and other large-scale construction machinery equipment. Most of the outer hoses are made of rubber, which has good wear resistance, corrosion resistance and heat resistance. [0003] Due to the relatively harsh working environment of construction machinery and equipment, the hydraulic oil pipe is not only affected by the oil pressure generated by the hydraulic oil, but also affected by external factors such as temperature, humidity and oil pollution. If things go on like this, the outer rubber hose of the hydraulic oil pipe is prone to mildew. It affects the performance of the ou...
