Embodiment 1

[0020] A preparation method of a dense steel wire braided rubber hose. The preparation methods of the materials of the inner rubber hose, the middle rubber layer and the outer rubber layer are the same, including the following steps:

[0021] a. Weigh each raw material in parts by weight, pass the raw rubber thinly on the open mill, with a roll distance of 0.5~0.8mm, and a time of 3~4min; relax the roll distance by 2~3mm, put in small materials in order, wait for small materials Eat up all, add the reinforcing agent and softener in batches. When adding the compounding agent, do not use the knife to knead. Add the vulcanization system. After all is eaten, adjust the roller pitch to 0.5~0.8mm, thin 3 times; then adjust the roller pitch to 2~3mm, make 5 triangle packages and 3 rolls, and cool the next film;

[0022] b. The test piece is vulcanized on a plate vulcanizing machine, and the vulcanization condition is 151℃×60min;

[0023] Among them: the materials for preparing the inner ru...

Embodiment 2

[0038] A preparation method of a dense steel wire braided rubber hose. The preparation methods of the materials of the inner rubber hose, the middle rubber layer and the outer rubber layer are the same, including the following steps:

[0039] Steps a and c are the same as in Example 1, but step b is different,

[0040] Step b: The test piece is vulcanized on a flat vulcanizing machine, and the vulcanization condition is 151℃×60min;

[0041] Among them: the materials for preparing the inner rubber tube, the middle rubber layer and the outer rubber layer are as follows:

[0042] The inner rubber of the inner rubber layer is prepared from the following raw materials by weight: raw rubber: nitrile rubber N1042 100kg, reinforcing agent: carbon black N660 90kg and white carbon black 10kg; softener: dioctyl phthalate 10kg; sample: zinc oxide 3kg, stearic acid 1kg, antioxidant 2,2,4-trimethyl-1,2-dihydroquinoline 2kg, sulfur 1kg, adhesive RC5kg and accelerator N-cyclohexyl -2-Benzothiazole s...

Abstract

The invention discloses a dense steel wire braided rubber hose and a preparation method thereof. The dense steel wire braided rubber hose includes an inner rubber layer, two steel wire layers braided outside the inner rubber layer, a middle rubber layer between the two steel wire layers and the outside of the steel wire layer outer rubber layer. The inner rubber of the inner rubber layer, the middle rubber of the middle rubber layer and the outer rubber of the outer rubber layer are all prepared from the following raw materials in parts by weight: raw rubber, reinforcing agent; softener, sample, adhesive and accelerator . The invention also discloses a preparation method of the dense steel wire braided rubber hose. The invention has the following advantages: the compact braided rubber hose of the invention has reasonable structure, small deformation under pulse pressure, light rubber hose, small bending radius, all properties of the finished product meet the requirements of SAEJ517R17 remarks, stable pulse performance, and the number of pulses exceeds 300,000 Second, greatly increasing the service life of the hose.

Description

technical field [0001] The invention relates to a steel wire braided rubber hose, and also relates to a preparation method of the rubber hose. Background technique [0002] At present, many heavy industry supporting enterprises have a great demand for SAE R17 series hoses, and the requirements are getting higher and higher, while SAER17 The 25×2-layer steel wire braided rubber hose has been tested. Well-known domestic rubber hose manufacturers only reach about 100,000 times, and rarely reach the 200,000 times required by the standard, which is far from meeting the needs of customers. The main reason for this problem is that the formula of the rubber compound and the design of the skeleton layer are unreasonable. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a dense steel wire braided rubber hose and its preparation method. The dense steel wire braided rubber hose is an SAE R17 rubber hose with c...
