Description
Technical field
The present invention relates to the preparation method of a kind of rubber with low zinc vulcanization leveller, belong to technical field of fine.
Background technology
In the sulfidization molding process of rubber, except will adding vulcanizing agent, vulcanization accelerator, scorch retarder, for improving vulcanization rate, generally also need to add vulcanization leveller, general conventional vulcanization leveller is zinc oxide, stearic acid etc., wherein zinc oxide not only can accelerate vulcanization rate, can also promote the cross-linking density of rubber, thus play strengthening action.For promoting the use properties of zinc oxide in rubber, use now more zinc oxide to be nano zine oxide, particle is thin, active high, very large at rubber industry consumption.But nano zine oxide due to particle thin, specific surface area is large, easily plays electrostatic, especially easily assembles conglomeration, particularly in compounding rubber, easily causes dispersion uneven, thus affects properties of rubber.In addition, nano zine oxide can along with the wearing and tearing of the rubber items such as tire, discarded and inevitably enter in water body, soil, cause zinc pollution, larger pollution hidden trouble is caused to ecotope, particularly larger to the procreative effect of animal, so rubber industry is also devoted to the new low zinc of exploitation or is carried out alternative nano zine oxide without the activating agent for rubber of zinc always, in the hope of reducing or stopping zinc pollution.
It take oyster shell whiting as the preparation method of the nano zine oxide of carrier that patent CN101352676A discloses a kind of, by soluble zinc salt wiring solution-forming, then oyster shell whiting is impregnated in solution, make zinc salts precipitate in oyster shell whiting by sodium hydroxide adjust ph, formed the nano zine oxide loaded in oyster shell whiting by calcining.Nano zine oxide loads in oyster shell whiting by the method, reduce the consumption of nano zine oxide in rubber, it also avoid the reunion of nano zine oxide, but the waste water containing sodium salt can be produced in zinc salts precipitate to the process of oyster shell whiting, environment-friendly type is poor, adds the cost of wastewater treatment.
Patent CN102382489A discloses a kind of method of method for preparing low-zinc vulcanized active agents by active carrier method, the method take clay as carrier, by organic modifiers, modification is carried out to clay, improve the charge capacity of clay to nano zine oxide, nano zine oxide is also by being impregnated into by clay in soluble Zn salt brine solution, then regulate pH by zinc salts precipitate, the method forming nano zine oxide finally by calcining obtains, can brine waste be produced equally, there is the problem that environment-friendly type is poor, cost for wastewater treatment is high.
Use soluble zinc salt as zinc source in prior art, the impact of granularity on performance about inert filler is not studied, and the granularity of each inert filler is all adopt the granularity (granularity that inert filler generally uses is 40-100 order) generally used.The present invention with inert filler and insoluble zinc carbonate for raw material, and the granularity of inert filler is studied, find through research, the granularity of inert filler is greater than 200 orders (such as 200-1200 order), most preferably be greater than 600 orders (such as 600-1200 order), the most preferably low zinc vulcanization leveller best results during 800-1200 order.The best results when granularity of zinc carbonate is 600-800 order.Select the inert filler of suitable particle size and zinc carbonate also can reduce the usage quantity of nano zine oxide.
In above-mentioned preparation method, water-fast inert filler and zinc carbonate are uniformly mixed at 40-50 DEG C of temperature.
In above-mentioned preparation method, water-fast inert filler and zinc carbonate mix under the stirring velocity of 120-150 r/min, preferred 130r/min.Under this stirring velocity, stir 2-3h and them can be made fully to contact.
In above-mentioned preparation method, water-fast inert filler and zinc carbonate are added to the water, and the consumption of water meets both dispersed.
In above-mentioned preparation method, calcining temperature is 550-600 DEG C.
The present invention has the following advantages:
1, the present invention's low zinc vulcanization leveller preparation method is simple and direct, water reusable edible, and pollution-free, energy-conserving and environment-protective, meet the policy requirements of national green chemical industry, cleanly production.
2, due to the existence of inert filler, nano zine oxide is conglomeration not easily, is very easy to dispersion, thus improves the use properties of zinc oxide in rubber.
3, obtained low zinc vulcanization leveller feature is nano zine oxide/inert filler mixture that nano zine oxide uniform loading is formed on inert filler surface, found by application test in rubber, low zinc vulcanization leveller containing 70% nano zine oxide with etc. the nano zine oxide effect of quality suitable, zinc consumption reduces 30%, reaches the object reducing nano zine oxide consumption, reduce zinc pollution.
Summary of the invention
The object of this invention is to provide a kind of preparation method of low zinc vulcanization leveller, the method is simple and easy to do, and pollution-free, energy-conserving and environment-protective, cost is low.
The concrete technical scheme of the present invention is as follows:
A preparation method for low zinc vulcanization leveller, step comprises: water-fast inert filler and zinc carbonate are added to the water, and makes them fully contact by stirring; Leave standstill after stirring, removing supernatant liquor, is fired to residuum till no longer producing gas, obtains low zinc vulcanization leveller.
The present invention adopts insoluble zinc carbonate as zinc source, with the inert filler with microvoid structure for carrier, finds that zinc carbonate is easy to when fully contacting with inert filler be attached to inert filler surface through test.Stir completely and by inert filler and zinc carbonate removing, not containing inorganic salt in remaining filtrate, can be reused, and can not exhaust emission be caused by filtration.
In above-mentioned preparation method, zinc carbonate in filter residue can be decomposed into nano zine oxide and carbonic acid gas when calcining, and inert filler can not change, the nano zine oxide be decomposed to form after having calcined can be dispersed in inert filler surface, form nano zine oxide/inert filler mixture, be low zinc vulcanization leveller by inert filler and load at the mixture that the nano zine oxide on inert filler surface is formed.
