Abstract
The invention discloses an environment-friendly rubber processing agent which comprises the raw materials by weight percent: 60-70% of resin, 28-32% of lubricating agent and 5-8% of surface active agent. The environment-friendly rubber processing agent is prepared by esterification reaction with unsaturated fatty acid and polyhydric alcohol instead of the traditional saponification reaction with unsaturated fatty acid and metallic oxide, so that the energy consumption is low in the production process, the emission of waste water, waste gas and carbon can be reduced, and the environmental protection requirements can be met; and the produced agent belongs to multifunctional zinc-free auxiliary agent and can effectively prolong the service life of rubber products.
Description
Technical field
The present invention relates to a kind of auxiliary chemicals and preparation method thereof, particularly relate to a kind of environment-friendly rubber processing aid and preparation method thereof.
Background technology
Over past ten years, the application of rubber processing aids is considered to the progress of rubber compounding technology in the high-performance elastic performance history, and the adding of processing aid is successfully mixing key.In sizing material, add the processing aid that lacks member's (1-3 part), can improve widely the processing characteristics of sizing material.As shorten mixing time and improve the dispersiveness of reinforcing filler in rubber, improve and with the phase structure of glue, and then the physical and mechanical properties of raising cross-linked rubber.Improve the flowability of sizing material, improve the extruded velocity of the mold filling performance (the particularly sizing material of high rigidity) of sizing material and raising sizing material and half-finished dimensional stability, surface smoothness.Improve the release property of vulcanizate.Increase the autohension of sizing material and sticking mutually.
In traditional tire production process, wherein mixing process is the maximum operation of current consumption, generally accounts for about 35% of total power consumption star.And in mixing process, Banbury mixer is again the equipment of this operation current consumption maximum, and after adding this environment-friendly rubber multifunctional assistant, can shorten mixing time 20%, i.e. the mixing energy consumption of minimum saving 20%, and reduce by 20% water coolant, therefore, in process of production, suitably use can improve the functional agent of melting effect and shortening mixing time, has significant economic benefit and social benefit.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of environment-friendly rubber processing aid and preparation method thereof is provided, adopting unsaturated fatty acids and polyvalent alcohol that cruelization reaction occurs generates, energy consumption is low in the production process, reduce waste water, waste gas and carbon emission, belong to without the zinc multifunctional assistant, prolong the work-ing life of rubber product.
The present invention is achieved by the following technical solutions:
A kind of environment-friendly rubber processing aid, raw material comprises as follows:
Resin, lubricant and tensio-active agent;
Raw material weight per-cent is: resin 60-70%; Lubricant 28-32%; Tensio-active agent 5-8%.

3, under churned mechanically condition, add the tensio-active agent of massfraction 5-8% in the reaction soln in step 2, and kept under the condition of 110-120 ℃ of temperature reaction 30-40 minute.
4, the reaction soln blowing in the step 3 is carried out the condensation granulation, being specially in temperature is condensation 4 hours under 25 ℃ the condition, namely obtains protecting the rubber processing aids particle.
The present invention has the following advantages:
1, environment-friendly rubber processing aid provided by the invention, to adopt unsaturated fatty acids and polyvalent alcohol to generate by esterification, traditional usefulness unsaturated fatty acids and metal oxide saponification reaction have been replaced, energy consumption is low in the production process, there are not waste water, exhaust gas emission, reduce carbon emission, meet environmental requirement.
2, this environment-friendly rubber multifunctional assistant is to adopt unsaturated fatty acids and polyvalent alcohol generation esterification to generate, and does not contain zinc element, belongs to without the zinc multifunctional assistant.Add this environment-friendly rubber multifunctional assistant in the rubber compounding, can shorten 20% mixing time, reduce by 10% energy expenditure, the cross-linked rubber ageing-resistant performance improves more than 10%, prolongs the work-ing life of rubber product.
Embodiment
The present invention will be further described below in conjunction with embodiment:
1, gets the C5 petroleum resin of massfraction 65%, the C5 petroleum resin are heated to 120 ℃ of molten states.
2, under churned mechanically condition, add massfraction 29% stearic acid in the C5 petroleum resin under molten state, and kept under the condition of 120 ℃ of temperature reaction 40 minutes.
3, under churned mechanically condition, add the polyoxyethylene glycol of massfraction 6% in the reaction soln in step 2, and kept under the condition of 120 ℃ of temperature reaction 40 minutes.
4, the reaction soln blowing in the step 3 is carried out the condensation granulation, being specially in temperature is condensation 4 hours under 25 ℃ the condition, namely obtains protecting the rubber processing aids particle.
Physical and mechanical properties result:
Can see from upper table, add this environment-friendly rubber multifunctional assistant in the rubber compounding, slight on the tensile strength impact of cross-linked rubber, the cross-linked rubber ageing-resistant performance improves more than 10%, prolongs the work-ing life of rubber product.This shows, this environment-friendly rubber processing aid can improve sizing material processing characteristics and melting effect, and does not reduce material mechanical property wherein, and its comprehensive benefit is remarkable, and application prospect is boundless.
