Abstract
The invention relates to a rubber formula, in particular to inner-layer rubber of a high styrene-reinforced high-pressure winding rubber hose, which aims to solve the problem existing in the prior art. The inner-layer rubber of the high styrene-reinforced high-pressure winding rubber hose is prepared from the following raw materials in parts by weight: 20 parts of nitrile rubber 2870, 5 parts of styrene, 1 part of active zinc oxide, 0.25 part of stearic acid, 0.5 part of anti-aging agent 4010NA, 2 parts of solid coumarone, 25 parts of carbon black N550, 2.5 parts of dioctyl ester, 0.23 part of accelerator CZ and 0.6 part of sulkol. The rubber hose manufactured by the invention has good oil resistance and good load performance, the rigidity of the inner-layer rubber during a winding technology process can be greatly increased, the machining difficulty is reduced, and the stress at definite elongation and the permanent deformation performance of the inner-layer rubber are increased, so that the quality stability of a product is increased.
Description
Technical field
The present invention relates to rubber compounding, the high pressure being specifically related to a kind of high-phenylethylene reinforcement is wound around rubber hose internal layer rubber.
Background technology
Rubber wire spiral rubber hose produces because of the very sex chromosome mosaicism of internal layer rubber in process of production and strangles pipe and catch up with pipe phenomenon very serious, causes rubber hose to occur serious quality problems, even occurs that batch scraps phenomenon.The very property size direct relation of internal layer rubber in steel wire winding steel the quality of steel wire winding rubber hose, ensures that sizing material has excellent processing characteristics and high very sex chromosome mosaicism just becomes a technical task while ensureing internal layer rubber high-strength degree, Gao Dingshen.
Summary of the invention
For Problems existing in existing technology, object of the present invention is just to provide
The high pressure of high-phenylethylene reinforcement is wound around a rubber hose internal layer rubber, has following weight fraction
Its preparation method is
Step 1 weighs:
The material in the present invention is weighed by rubber production formulation ratio;
Step 2 banburying: use 55 liter milling machines to carry out banburying, load weighted paracril/high styrene rubber is directly added in Banbury mixer, pressure floating weight, after 60 seconds and temperature adds active zinc flower, stearic acid, antioxidant 4010NA, solid coumarone, carbon black N550, dibutyl ester higher than mentioning floating weight when 80 DEG C, the banburying of pressure floating weight, mention floating weight after 120 seconds, continue to press top bolt after the powder of spilling is swept Banbury mixer, discharge after 150 seconds; The sizing material of mixing one-tenth block is transferred to bottom sheet after logical three times of mill pull-up, park after 6 hours stand-by;
Step 3 is filtered:
By park rubber unvulcanizate on a mill until fully after heat refining under become the adhesive tape of wide 10 centimetres, thick 1 cm to filter through filter;
Step 4, sulphurization:
The adhesive tape of having filtered is added accelerant CZ and sulfur flour in an other mill, eats after powder completes and play 5 triangle bags, bottom sheet, hang cool after tank cooling, detect qualified rear stand-by.
The present invention be a kind of use paracril, high styrene rubber and mixing of rubber, as high pressure steel wire be wound around rubber hose internal layer rubber, the present invention make rubber hose there is excellent oil resistance and load performance.This kind of compounded rubber can improve the very property of internal layer rubber in winding process process greatly, reduce difficulty of processing, improve the stress at definite elongation of internal layer rubber and tension set performance thus improve the stability of quality of item, use this kind of internal layer rubber can lower or remove from interior pipe frozen cooling operation, thus play the effect of energy-conserving and environment-protective.This patent of invention use paracril (NBR) and high styrene rubber and method solve the problem of complete processing and constant product quality.Be plastic state under high styrene rubber normal temperature, there is again when temperature is greater than 80 DEG C the characteristic of rubber, rubber processing machinery can be used to process, and under high temperature, viscosity is lower, be convenient to processing.Simultaneously high-phenylethylene is slight high and sulfur sulfide system can be used to carry out sulfuration, thus with and paracril produce sizing material altogether.
Embodiment
Be further detailed below in conjunction with the content of embodiment to invention:
Embodiment 1
The high pressure of high-phenylethylene reinforcement is wound around a rubber hose internal layer rubber, has following weight fraction
Its preparation method is
Step 1 weighs:
The material in the present invention is weighed by rubber production formulation ratio;
Step 2 banburying:
55 liter milling machines are used to carry out banburying, load weighted paracril/high styrene rubber is directly added in Banbury mixer, pressure floating weight, after 60 seconds and temperature adds active zinc flower, stearic acid, antioxidant 4010NA, solid coumarone, carbon black N550, dibutyl ester higher than mentioning floating weight when 80 DEG C, the banburying of pressure floating weight, mention floating weight after 120 seconds, continue to press top bolt after the powder of spilling is swept Banbury mixer, discharge after 150 seconds; The sizing material of mixing one-tenth block is transferred to bottom sheet after logical three times of mill pull-up, park after 6 hours stand-by;
Step 3 is filtered:
By park rubber unvulcanizate on a mill until fully after heat refining under become the adhesive tape of wide 10 centimetres, thick 1 cm to filter through filter;
Step 4, add sulphur:
The adhesive tape of having filtered is added accelerant CZ and sulfur flour in an other mill, eats after powder completes and play 5 triangle bags, bottom sheet, hang cool after tank cooling, detect qualified rear stand-by.
Steel wire winding internal layer rubber Typical physical performance of the present invention is as following table:
| Physicals | Detect data |
| Tensile strength at yield (MPa) | 18.9 |
| Tensile yield (%) | 226 |
| 100% stretches (MPa) surely | 9.02 |
| Tension set (%) | 6 |
| Hardness (Shao A) | 86 |
Under high styrene rubber normal temperature of the present invention, there is very high hardness, thus impel there is during rubber unvulcanizate normal temperature higher very property, be convenient to steel wire winding, especially steel wire winding during summer high temperature weather;
There is during high styrene rubber high temperature very low viscosity, therefore greatly can reduce energy consumption in the process engineerings such as banburying, heat refining, filtration, play the effect of energy-conserving and environment-protective;
Use this internal layer rubber can reduce or remove from the use of refrigerating apparatus, thus lower the use of freonll-11 and the loss of electric energy, play the effect of energy-conserving and environment-protective further.
