Abstract
The invention discloses sulfur-free and low-temperature vulcanized rubber, and relates to a sizing material. The formula of the sulfur-free and low-temperature vulcanized rubber comprises the following components: chloroprene rubber, magnesium oxide, zinc oxide, zinc stearate, black carbon 550, black carbon 330, naphthenic oil and a vulcanization accelerant; a vulcanization temperature is 120 DEG C. An underwater sealing hose produced by using the formula of the chloroprene rubber which is provided by the invention has the characteristics of good water sealability, water penetration resistance, ozone aging resistance, ultraviolet radiation aging resistance, seawater corrosion resistance, and long service life in the usage temperature range of 50 DEG C below zero to 60 DEG C, and also has favorable mechanical properties; current use requirements can be met quite well.
Description
Technical field
The present invention relates to a kind of sizing material, particularly relate to a kind of without sulphur cold rubber.
Background technology
Under water detecting sensor water-lute sleeve pipe be isolated outside water to sensitive detectors part infiltration in pipe, anti-sealing to a kind of flexible sleeve of its corrosion failure, major function be the sensing element device safety and stability ensured in pipe operation.
Domestic used sealing material mainly cast polyurethane material at present, because such material is generally obtained by polyaddition by isocyanic ester and polyether glycol or polyester polyol, due to the restriction of own material character, the water-intake rate of this kind of sealing material is caused to exceed the requirement of use, the urethane swelling behavior that meeting occurrence degree is different in water and hydrolysis reaction can destroy work-ing life and the stability in use of sensitive components in addition, are therefore badly in need of a kind of type material and replace current material.Be limited to actual environment for use limit, can supply our selection materials mainly elastomeric material, because sensor internal has cable, its insulation layer extremely can the temperature of resistance to less than 125 DEG C, therefore, it is possible to what at utmost meet above-mentioned requirements is chloroprene rubber.
The neoprene metal hose of water-lute cannot sulfur-bearing, because element sulphur can be passed in time and move, solder joint and the sensitive components surface metallization material of final and sensor react and sensor are destroyed, and affect its stability in use and life-span.
In the neoprene metal hose playing water-lute effect, also cannot select the raw material of sulfur-bearing, this kind of vulcanizing agent cannot be selected to carry out sulfuration, therefore we need to carry out creationary adjustment to formula.
In Rubber processing, comprise plasticate, mixing, roll or extrude, the basic working procedure such as shaping and sulfuration, each operation has different requirements for goods, coordinates respectively with some non-productive operations.In order to add in rubber by various required Synergist S-421 95, first rubber needs to improve its plasticity through over-mastication; Then by mixing, carbon black and various rubber ingredients and rubber are uniformly mixed into sizing material; Sizing material makes definite shape blank through extrusion; Make it combine with the textile materials (or and metallic substance) through rolling kiss-coating or gluing again and be shaped to work in-process; Eventually pass sulfuration and make elastomeric the finished product.
In sum, sulphur and sulfocompound cannot occur in chloroprene rubber vulcanization system, and adjustment vulcanization system is the top priority that will solve.
Summary of the invention
The object of the present invention is to provide a kind of without sulphur cold rubber, one has resistant to water penetration and resistance to ozone and ultraviolet and corrodes, and within the scope of wide use temperature the Chloroprene rubber formula of longer service life feature, make it meet and the requirement of water-lute effect play to responsive Detection theory device under water.
The object of the invention is to be achieved through the following technical solutions:
A kind of component without sulphur cold rubber composition of the present invention and ratio of quality and the number of copies are:
Chloroprene rubber 100;
Magnesium oxide 1-2;
Zinc oxide 0-1;
Zinic stearas 2-6;
Carbon black 55010-50;
Carbon black 33055-70;
Naphthenic oil 10-25;
Na-221-4。
Above-mentioned sizing compound formula carries out sulfuration and forms at 120 DEG C of temperature.
Utilizing the synergy of zinc oxide and Zinic stearas in the present invention, the sulfuration making product keep suitable, avoiding adopting separately a kind of containing zinc auxiliary agent sulfurate activity and the unmatched drawback of vulcanization system.
Adding carbon black 550 and carbon black 330 by adding in the present invention simultaneously, making neoprene flexible rubber hose both can ensure good reinforcing effect, good processing characteristics can be ensured again, well ensure that the over-all properties of sebific duct goods.
Add the naphthenic oil of high flash point in the present invention, ensure that water-lute sebific duct has good flexibility, add the characteristic of chloroprene rubber self, make the water-lute flexible pipe adopting Chloroprene rubber formula of the present invention to produce have very wide use temperature scope, current service requirements can be better met.
The Na-22 used in the present invention is not containing sulphur or element sulphur, and this can be avoided element sulphur to the destruction of the solder joint of sensor and sensitive components surface metallization material.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
Each component in Chloroprene rubber formula is in mass fraction:
| Formula number | Composition | Example 1 | Example 2 | Example 3 | Example 4 |
| 1 | Chloroprene rubber | 100 | 100 | 100 | 100 |
| 2 | Magnesium oxide | 1 | 1.2 | 2 | 1.5 |
| 3 | Zinc oxide | 0.8 | 0.5 | 0.5 | 0 |
| 4 | Zinic stearas | 2 | 3.5 | 4.5 | 6 |
| 5 | Carbon black 550 | 30 | 45 | 40 | 10 |
| 6 | Carbon black 330 | 25 | 10 | 25 | 65 |
| 7 | Na-22 | 3 | 2.2 | 4.0 | 3.7 |
| 8 | Naphthenic oil | 10 | 18 | 10 | 15 |
Make film by starting material in implementation column formula and carry out testing inspection, adopt this Chloroprene rubber formula as follows with the contrast of the chloroprene rubber performance of sulfur cross-linking:
Wherein: it is " Tianjin quality monitoring testing station the 42 station " that free sulphur and total sulphur content detect unit, and non-sulfur cross-linking temperature is 120 DEG C, sulfur cross-linking temperature 155 DEG C.
Can be drawn by the data of upper table, the Chloroprene rubber formula mentioned in presents is compared with the chloroprene rubber of sulfur cross-linking, water-lute requirement is played according to responsive Detection theory device under water, good seal performance, resistant to water penetration, resistance to ozone ageing, ultraviolet ray ageing and sea-water corrosion, the feature of the long service life within the scope of-50 ~ 60 DEG C of use temperatures, can well meet current service requirements.
