Description
Technical field
The present invention relates to rubber materials, particularly a kind of black oil resistant carpet rubber and preparation method thereof.
Background technology
Rubber carpet can be widely used in the related service industries such as all kinds of manufacturing enterprise, food and drink hotel, large-scale mall and place of public amusement, particularly along with the further lifting of the flourish of the Third Industry and people's environmental consciousness, the market requirement of rubber carpet will increase severely with day.
And along with the expansion of use range, the requirement of human consumer is also more and more higher, in order to adapt to the harsher environment for use such as place such as factory, laboratory, the oil-proofness improving carpet becomes an important indicator of rubber carpet.The domestic R and D for oil resistant carpet are at present also few, therefore develop there is high strength, tear-resistant, oil resistant, resistance to alkali cleaning, ageing-resistant rubber carpet become a urgent task, has wide market outlook.
Summary of the invention
Object of the present invention is exactly for the problems referred to above, provides a kind of over-all properties good, the rubber carpet goods of long service life, oil resistant, resistance to alkali cleaning and prepare the method for this rubber.
For achieving the above object, the invention provides following technical scheme, black oil resistant carpet rubber, it is made up of the component of following weight percent:
Paracril 42-47%,
Black-reinforced weighting agent 33-38%,
Softening agent 7-12%,
Anti-aging agent+promoting agent 3-6%,
Tackifying resin 1-2%,
Sulphur 0.5-1.0%,
Promotor 0.5-1.5%.
Preferably, the described paracril trade mark is NBR3380.This kind of elastomeric material propylene hydrocarbon content is 33%, and Mooney about 80 belongs to high propylene hydrocarbon, and high Mooney molecular weight rubber is large, and oil resistance is good, physicals as tensile strength, the performance such as to tear relatively excellent.
Preferably, described tackifying resin is 1102.Effectively can increase the bonding of rubber and non-woven fabrics, make it not easily separated, high relative to general tackifying resin quality, impurity is few.
Preferably, described softening agent is DOS (dioctyl sebacate).Its plasticization effect is good, and consistency is good, effectively can improve the flexibility of sizing material, improve its low-temperature performance.
Preferably, described black-reinforced weighting agent is carbon black N774.It easily disperses in sizing material, and has the effect increasing packing volume, reduce costs.
Preferably, the ratio of described paracril and black-reinforced weighting agent is at least 1.2: 1.
Preferably, the ratio between described black-reinforced weighting agent and softening agent is between 3: 1 ~ 5: 1.
The present invention also provides a kind of preparation method of black oil resistant carpet rubber, comprises the following steps successively:
(1) get the raw materials ready: according to said ratio, by paracril, black-reinforced weighting agent, softening agent, tackifying resin, place after weighing respectively, together with anti-aging agent+promoting agent and sulphur fit over by said ratio, form batching A, promotor is fitted over and forms batching B together;
(2) first is mixing: paracril and batching A are dropped into mixer mixing 30-60 second, then continues to drop into carbon black and softening agent mixing 60-120 second, is dumped into slice on cutting machine, makes rubber unvulcanizate A then continue mixing 60-90 second after cleaning after;
(3) second is mixing: rubber unvulcanizate A and batching B is dropped into mixer mixing 60-90 second, is dumped into slice on cutting machine, completes preparation then continue mixing 30-60 second after cleaning after.
In (1) described step, mix after first sulphur and anti-aging agent+promoting agent being weighed; And paracril and batching A are dropped into mixer mixing, such optimization carried out calendering process, by sulphur and anti-aging agent, that promoting agent joins first is mixing, solve the problem that sulphur not easily disperses, reach rubber unvulcanizate to be uniformly dispersed, improve physicals, decrease product defect.
The present invention selects suitable paracril as body of rubber material, rational formulation ratio, make product except acidproof, corrosion-resistant, the weather-proof feature with ordinary rubber carpet, oil resistance is good, and unit elongation is good, long service life, physical and mechanical properties is good, and use range is wide, can do ground cushion in hotel, hotel etc., also can in factory, laboratory comparatively uses in severe rugged environment.
Embodiment
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment
The composition proportion of examples of implementation 1-6 is in table 1.Black oil resistant carpet rubber of the present invention is manufactured according to following steps:
(1) get the raw materials ready: proportioning according to claim 1, by paracril, carbon black, softening agent, tackifying resin, place after weighing respectively, anti-aging agent+promoting agent+sulphur fits over by said ratio and forms batching A together, promotor is fitted over and forms batching B together;
(2) first is mixing: paracril and batching A are dropped into mixer mixing 30-60 second, then continues to drop into carbon black and softening agent mixing 60-120 second, is dumped into slice on cutting machine, makes rubber unvulcanizate A then continue mixing 60-90 second after cleaning after;
