Abstract
The invention discloses a modified rubber material, which comprises the following raw materials in weight percentage: 10 percent of natural rubber, 20 percent of chlorinated polyethylene rubber, 5 percent of melamine, 8 percent of urea, 5 percent of isopropanol, 5 percent of sulphur, 4 percent of maleic anhydride, 15 percent of carbon black, 6 percent of aromatic hydrocarbon oil, 6 percent of anti-aging agent, 10 percent of auxiliaries, 2 percent of zinc oxide, 2 percent of nano calcium phosphate, 1 percent of sodium sorbate, and 1 percent of fluorapatite. The modified rubber provided by the invention has favorable weatherability, and the elasticity performance of the modified rubber is not reduced remarkably compared with the elasticity performance of the natural rubber. Compared with the natural rubber, the modified rubber has the advantage of greatly improved oxidation-resistivity capacity, and correspondingly, the ageing-resistant performance is remarkably improved.
Description
Technical field
The present invention relates to technical field of rubber material, be specifically related to the modified rubber material based on natural rubber.
Background technology
Although natural rubber has good springiness, intensity is high, the advantage of good combination property, natural rubber price, and cost is high, and the ozone resistance of natural rubber and ageing-resistant performance more and more do not meet the demands.
Summary of the invention
The object of the present invention is to provide a kind of modified rubber material, be intended to the problem solving natural rubber weathering resistance difference.
Technical scheme of the present invention is as follows:
A kind of modified rubber material, wherein, be made up of following raw material according to weight percent: natural rubber 10%, chlorinated polyethylene rubber 20%, trimeric cyanamide 5%, urea 8%, Virahol 5%, sulphur 5%, maleic anhydride 4%, carbon black 15%, aromatic hydrocarbon oil 6%, anti-aging agent 6%, auxiliary agent 10%, zinc oxide 2%, nano-calcium phosphate 2%, sodium sorbate 1%, fluorapatite 1%.
Described modified rubber material, wherein, described anti-aging agent is antioxidant D CP and the anti-aging agent RD mixture according to 2:1 weight ratio.
Described modified rubber material, wherein, described auxiliary agent is calcium propionate and the stearic acid mixture according to 1:1 weight ratio.
Beneficial effect: the invention provides a kind of modified rubber, the modified rubber prepared by the method has good weathering resistance, and does not have obvious decline compared to its original elastic performance of natural rubber.And compared to natural rubber, modified rubber oxidation resistance of the present invention promotes greatly, its ageing-resistant performance corresponding is obviously strengthened.
Embodiment
For making object of the present invention, technical scheme and advantage clearly, clearly, the present invention is described in more detail below.
The raw material that the present invention uses, does not do specified otherwise, is conventional use raw material in industry, is commercially available prod.
Embodiment
Each raw material is weighed: natural rubber 10%, chlorinated polyethylene rubber 20%, trimeric cyanamide 5%, urea 8%, Virahol 5%, sulphur 5%, maleic anhydride 4%, carbon black 15%, aromatic hydrocarbon oil 6%, anti-aging agent 6%, auxiliary agent 10%, zinc oxide 2%, nano-calcium phosphate 2%, sodium sorbate 1%, fluorapatite 1% according to following weight percent.
Wherein, described anti-aging agent is antioxidant D CP and the anti-aging agent RD mixture according to 2:1 weight ratio, and described auxiliary agent is calcium propionate and the stearic acid mixture according to 1:1 weight ratio.
As above proportioning raw materials is utilized to be prepared as follows: natural rubber 10%, chlorinated polyethylene rubber 20%, trimeric cyanamide 5% drops in Banbury mixer, pressurization 20Mpa plasticates, when temperature reaches 120 degree, binder removal, the sizing material of plasticating is dropped in Banbury mixer, pressurize mixing 5 minutes, then anti-aging agent 6% is dropped into, auxiliary agent 10%, zinc oxide 2%, nano-calcium phosphate 2%, sodium sorbate 1%, fluorapatite 1%, pressurize mixing 1 minute, then urea 8% is added, Virahol 5%, sulphur 5%, maleic anhydride 4%, carbon black 15%, aromatic hydrocarbon oil 6%, carry out pressurization mixing, pressure is 20Mpa, when temperature reaches 105 degree, add sulphur, accelerant NOBS, it is mixing that co-crosslinker TCY carries out pressurization, when temperature reaches 115 degree, binder removal, carry out thick logical in mill, then slice.
Performance test:
Tensile strength: 18.8MPa;
Elongation at break: 415%;
Resistance to ozone: 25 DEG C, 24h, ozone concn 0.025%, without cracking;
Ageing-resistant: 120 DEG C, 150h, tensile strength retention 88.1%, elongation at break conservation rate 78.8%;
Cold-resistant experiment: (-40 DEG C, 4h): flawless.
From above determination experiment, the ageing-resistant performance of modified rubber prepared by the present invention and endurance can all obviously be better than traditional natural rubber.
The invention provides a kind of modified rubber, the modified rubber prepared by the method has good weathering resistance, and does not have obvious decline compared to its original elastic performance of natural rubber.And compared to natural rubber, modified rubber oxidation resistance of the present invention promotes greatly, its ageing-resistant performance corresponding is obviously strengthened.
Should be understood that, application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to claims of the present invention.
