Summary of the invention
The object of the present invention is to provide a kind of rubber ring and preparation method thereof, solving existing rubber ring adopts traditional natural rubber preparation to cause that intensity is low, elasticity is little, yielding and easily aging, and in preparation complex process and add the problem that objectionable impurities works the mischief to human body and environment.
For solving above-mentioned technical problem, the present invention by the following technical solutions:
A kind of rubber ring, comprising weight ratio is that 50%-80% natural rubber, 10%-40% zinc oxide, 1%-5% promotor, 1%-5% anti-aging agent, 1%-3% vulcanizing agent and 1%-2% look female.
Further technical scheme is, described promotor be CBS.D.M.TT (stilbene biphenyl sodium disulfonate. vulkacit D .2-thiol benzothiazole. tetramethyl-thiuram disulfide), described anti-aging agent is RD (2,2,4-trimethylammonium-1,2-dihyaroquinoline polymer), molecular formula is (C12H15N) n, and described vulcanizing agent is sulphur.
A preparation method for rubber ring, comprises the following steps:
Be that 50%-80% natural rubber, 10%-40% zinc oxide, 1%-5% promotor, 1%-5% anti-aging agent, 1%-3% vulcanizing agent and 1%-2% look female mix and blend forms rubber in 15-30 minute by weight ratio;
Take out rubber to put into rolling machine and be rolled into sheet, then put into the rubber bar that banding machine is divided into required width;
The mould again rubber bar being put into thermocompressor, with shaping rear demoulding temperature hot pressing 50-80 second of 150 degree-180 degree, can generate finished product with room temperature cooling.
Further, described rolling machine is the thermocompressor with 100----500 ton pressure.
Compared with prior art, the invention has the beneficial effects as follows:
Preparation method's technique that the present invention adopts is simple, and saves manpower in production process and greatly reduce the impact on environment, and the rubber ring intensity produced is high, and elasticity is large, not easily aging and not yielding.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with and embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Invention shows an a kind of embodiment of rubber ring: a kind of rubber ring, comprising weight ratio is that 50%-80% natural rubber, 10%-40% zinc oxide, 1%-5% promotor, 1%-5% anti-aging agent, 1%-3% vulcanizing agent and 1%-2% look female.
Wherein said zinc oxide is the effect of activation rubber; The effect of vulcanizing agent is that the strip molecular structure of rubber is changed over network molecular structure to increase rubbery intensity; Promotor is the time speed degree promoting sulfidization molding; Anti-aging agent is the stability of molecule increasing rubber product.
According to the preferred embodiment that invention shows a kind of rubber ring, described promotor be CBS.D.M.TT (stilbene biphenyl sodium disulfonate. vulkacit D .2-thiol benzothiazole. tetramethyl-thiuram disulfide), described anti-aging agent is RD (2,2,4-trimethylammonium-1,2-dihyaroquinoline polymer), molecular formula is (C12H15N) n, and described vulcanizing agent is sulphur.
Invention shows an embodiment of a kind of preparation method of rubber ring: a kind of preparation method of rubber ring, comprises the following steps:
Be that 50%-80% natural rubber, 10%-40% zinc oxide, 1%-5% promotor, 1%-5% anti-aging agent, 1%-3% vulcanizing agent and 1%-2% look female mix and blend forms rubber in 15-30 minute by weight ratio;
Take out rubber to put into rolling machine and be rolled into sheet, then put into the rubber bar that banding machine is divided into required width;
The mould again rubber bar being put into thermocompressor, with shaping rear demoulding temperature hot pressing 50-80 second of 150 degree-180 degree, can generate finished product with room temperature cooling.
According to a preferred embodiment of the preparation method of a kind of rubber ring of the present invention, described rolling machine is the thermocompressor with 100----500 ton pressure.
Enumerate the concrete optimum ratio of a kind of rubber ring of several the present invention and the preparation method of corresponding proportioning below:
Example 1: by weight percentage, select 55% polyisoprene, 35% zinc oxide, 5% promotor, 2% anti-aging agent, 1% sulphur, 2% look mother put into Banbury mixer and stir and form block rubber in 25 minutes, taking-up rubber is put into rolling machine and is rolled into sheet, put into the rubber bar that banding machine is divided into required width again, the mould again rubber bar being put into the thermocompressor of 100 tons of pressure, with the temperature hot pressing shaping rear demoulding in 80 seconds of 150 degree, can generate finished product with room temperature cooling.Zinc oxide is in effect (the larger surface viscosity of content is larger, and anti-slip effect is better) this example of activation rubber, and it is more that the content of zinc oxide adds, and the viscosity of rubber ring is larger, and anti-slip effect is better.
Example 2: by weight percentage, select 60% polyisoprene, 30% zinc oxide, 3% promotor, 2% anti-aging agent, 1% sulphur, 1% look mother put into Banbury mixer and stir and form block rubber in 25 minutes, taking-up rubber is put into rolling machine and is rolled into sheet, put into the rubber bar that banding machine is divided into required width again, the mould again rubber bar being put into the thermocompressor of 150 tons of pressure, with the temperature hot pressing shaping rear demoulding in 90 seconds of 160 degree, can generate finished product with room temperature cooling.The effect of vulcanizing agent the strip molecular structure of rubber is changed over network molecular structure to increase rubbery intensity (the more elastic strengths of content are larger), and in this example, the content of sulphur is more, and the elastic strength of rubber ring is larger.
Example 3: by weight percentage, select 65% polyisoprene, 25% zinc oxide, 5% promotor, 2% anti-aging agent, 1% sulphur, 2% look mother put into Banbury mixer and stir and form block rubber in 20 minutes, taking-up rubber is put into rolling machine and is rolled into sheet, put into the rubber bar that banding machine is divided into required width again, the mould again rubber bar being put into the thermocompressor of 150 tons of pressure, with the temperature hot pressing shaping rear demoulding in 100 seconds of 160 degree, can generate finished product with room temperature cooling.Anti-aging agent increases in stability of molecule (content is more large more durable) this example of rubber product, and the content of anti-aging agent is more, and rubber ring is more durable, and duration of service is longer.
Anti-aging agent in the various embodiments described above increases the stability of molecule (content is more large more durable) of rubber product; The effect of vulcanizing agent the strip molecular structure of rubber is changed over network molecular structure to increase rubbery intensity (the more elastic strengths of content are larger); Zinc oxide is the effect (the larger surface viscosity of content is larger, and anti-slip effect is better) of activation rubber.
Rubber ring of the present invention can be arbitrary shape, can be circular, rhombus, oval or other arbitrary shapes.
