Abstract
The invention discloses a supported nano zinc oxide composite material, which is prepared by adopting the following method of: adding carbon black for rubber into a zinc sulfate solution, adding urea, stirring uniformly, heating to the temperature of between 90 and 100 DEG C, and reacting for 4 to 6 hours at the temperature; filtering after the reaction, and washing filter cakes by using deionized water till sulfate radicals do not exist; and drying the filter cakes, calcining for 2 to 4 hours at the temperature of between 200 and 300 DEG C under the protection of an inert gas, and thus obtaining the supported nano zinc oxide composite material. According to the supported nano zinc oxide composite material, nano zinc oxide is supported on the carbon black for the rubber, so that the nano zinc oxide has high activity; and the utilization rate of zinc atoms is high, and the adding quantity of the zinc atoms is 30 to 50 percent of common zinc oxide, so that the nano zinc oxide resource can be greatly saved.
Description
Technical field
The present invention relates to a kind of load nano-zinc oxide composite material, also relate to simultaneously a kind of rubber item that adopts this matrix material.
Background technology
Zinc oxide is the requisite additive of rubber item, is vulcanization leveller and the strengthening agent of rubber, has in the world 50% zinc oxide to flow to rubber industry.Common Zinc oxide particles is larger, and is active low, large usage quantity.Nano zine oxide is little because of its particle diameter, and specific surface area is large, and adsorption activity is strong, thereby has surface effects and high reactivity.Nano zine oxide can be realized combination on the molecular level with rubber molecule, is used for rubber and can gives full play to the sulfuration promoter action, improve the performance of rubber, but its consumption decrease has reduced to the dependence of zinc resource and the environmental pollution that brings thereof.Yet, although the activity of nano zine oxide is higher, but because the add-on of nano zine oxide in rubber item seldom, often because disperse insufficient its zinc oxide atom that in Vulcanization Process of Rubber, really plays a role that causes to remain minority, the atom utilization that is zinc oxide is very low, major part only is present in the rubber item as filler, thereby has affected the performance of rubber item.
Summary of the invention
The purpose of this invention is to provide the high loaded nano zinc oxide composite of a kind of nano zine oxide atom utilization.
In order to realize above purpose, the technical solution adopted in the present invention is: a kind of loaded nano zinc oxide composite, adopt following method to be prepared from:
1) rubber grade carbon black is joined in 10～20% the solution of zinc sulfate, the add-on of carbon black is 10～50% of zinc sulfate quality, then add urea according to 0.4～0.6 times of zinc sulfate quality and stir, be warming up to 90～100 ℃ and under this temperature, reacted 4～6 hours;
2) filter after the reaction, with filter cake with deionized water wash to sulfate radical-free;
3) with behind the filtration cakes torrefaction, under protection of inert gas, in 200～300 ℃ of lower calcinings 2～4 hours, obtain the loaded nano zinc oxide composite.
As further improvement, the described churning time of step 1) is 20～90 minutes.
As further improvement, the described precipitation drying temperature of step 3) is 85 ℃.
The application's loaded nano zinc oxide composite, adopt the very large rubber black of surface-area to do carrier, at first make zinc sulfate be deposited in carbon blacksurface with the form of zinc carbonate, then pyrolytic decomposition generates the long-pending very large nano zine oxide of layer of surface on the surface of carbon black, nano zine oxide with respect to other form has higher activity, and carbon black is larger with respect to the particle diameter of nano zine oxide, and its amount ratio nano zine oxide in rubber item is much bigger, therefore the nano zine oxide that loads on carbon blacksurface is easy to realize Uniform Dispersion, therefore adopt loaded nano zinc oxide composite of the present invention can improve significantly the zinc in zinc oxide atom utilization, thereby reduce the consumption of zinc oxide, its consumption only is 30%～50% of common zinc oxide, can greatly save nano oxidized zinc resource.
