Abstract
An oil-resisting and anti-acid mixed material and its production are disclosed. The mixed material consists of chlorinated polyethylene rubber, butadieneacrylonitrile latex/polyvinyl chloride (70/30) alloy, oligomer ester, metacrylic acid zinc, metacrylic acid magnesium, filler, improver, vulcanizing agent and plasticizerDOP. The process is carried out by milling and membrane penetrating. It has long life and can be used for rubber-covered roller, hose, lining material of chemical corrosive-proof container.
Description
Technical field
The invention belongs to the rubber item technical field, relate in particular to the mixed material of a kind of not only wear-resisting but also oil resistant, acid and alkali-resistance.
Background technology
On the production line of stainless steel materials, in order to adapt to different production environments, the rubber roll of setting is made of nitrile rubber, chloroprene rubber, polyamine rubber and isoprene-isobutylene rubber respectively.The rubber roll oil resistant that constitutes by nitrile rubber but acid and alkali-resistance not, the rubber roll acid and alkali-resistance that is made of chloroprene rubber but oil-proofness is poor is although the wear-resisting chance of the rubber roll water that is made of polyamine rubber is easily softening, the rubber roll oil resistant acid and alkali-resistance that is made of isoprene-isobutylene rubber but bad mechanical property.Use different rubber unvulcanizate roll materials, make different rubber rolls scrap the time limit difference, and short (long four, five months of the work-ing life of various rubber rolls, short two, three months), in process of production, need the different rubber roll of the replacing of not timing and change frequently, had a strong impact on production efficiency.In addition, because kind, the quantity of rubber roll are more, need take very big warehouse space, it is unclear to make that the store keeper writes down, and very easily causes the confusion of production.
Summary of the invention
Purpose of the present invention just provides the mixed material of a kind of not only wear-resisting but also oil resistant, acid and alkali-resistance.
For achieving the above object, the technical solution used in the present invention is:
The mixed material of a kind of oil resistant, acid and alkali-resistance includes following components in part by weight:

Wherein, include carbon black in the described filler.
The method of the mixed material of preparation oil resistant, acid and alkali-resistance comprises the following steps:
The first step is that paracril/polyvinyl chloride alloy of 70/30 and oligomer ester and zinc methacrylate are inserted in the rubber internal mixer by weight with chlorinated polyethylene rubber, ratio,---the 180 ℃ of glue refinings 8---15 minutes that make temperature keep 150, again magnesinm methacrylate, stearic acid are presented to successively glue refining 4 in the Banbury mixer---8 minutes, and then filler, plasticizer DOP are inserted glue refining 5 in the Banbury mixer, and---shut down after 10 minutes and turn over warehouse discharging, cold is to 40---are stand-by below 65 ℃;
Second step joined temperature 40 with the sheet rubber that the glue refining forms---in 65 ℃ the rubber mixing mill, add promotor, vulcanizing agent, packing more successively at least three times, adjust roll spacing to 0.5---1.2 mm thick of glue refining machine, thin-pass at least four times, get final product the mixed material of oil resistant, acid and alkali-resistance.
Utilize the performance perameter of the mixed material of oil resistant that method provided by the present invention is prepared into, acid and alkali-resistance to be:
1, shore hardness is that 65 ± 5 degree, tensile strength are that 17.5 ± 0.5MPa, tensile yield are 480-500%, Akron abrasion (cm
2) be 0.050g.
2, the parameter of oil resistant experiment is:
| Soak 1 mark oil (100 ℃ * 70 hours) performance variation rate | Soak 3 mark oil (100 ℃ * 70 hours) performance variation rates |
| Hardness ± 3 | Hardness ± 2 |
| Tensile strength-2% | Tensile strength-4% |
| Draw short elongation-20% | Draw short elongation-20% |
| Volume-3% | Volume+1.0% |
3, the parameter of acidproof experiment is:
| Behind the immersion fluid (100 ℃ * 70 hours) | Soak the volume change of various liquid | Hardness | Volume |
| 70% sulfuric acid | Excellent | 25% chromic acid solution (80 ℃ * 7 days) | 0％ | +1.0％ |
| 30% superchlorination hydrogen | Excellent | 5% chlorine bleach liquor (80 ℃ * 7 days) | -3 degree | +8.4％ |
| 13% superchlorination hydrogen | Excellent | 60% salpeter solution (20 ℃ * 60 days) | 0％ | +4.2％ |
| 20% hydrochloric acid | Very | |||
| 20% nitric acid | Very |
4, the mixed material of this oil resistant, acid and alkali-resistance not only can be used for the various rubber rolls in the stainless steel production line, but also can be used for the substrate layer material of various sebific ducts, chemical anticorrosion container.According to detection, the bonding stripping strength of this mixed material and 45# steel significantly improves 9%, increases work-ing life more than 1 year.
