Abstract
The invention discloses an emulsified coal tar pitch which is prepared from the following raw materials: 500 g of coal tar pitch, 500 g of water, 3 g of an asphalt emulsifier and 1 g of bentonite. A preparation method of the emulsified coal tar pitch comprises the following steps: adding bentonite into the asphalt emulsifier; mixing the mixture of bentonite and the asphalt emulsifier with water to obtain an emulsion; and using coal tar pitch and the emulsion to prepare the emulsified coal tar pitch. According to the preparation method of the emulsified coal tar pitch, coal tar pitch is emulsified by adding bentonite into the asphalt emulsifier. Thus, problems of coal tar pitch emulsification and stabilization after emulsification are solved.
Description
Technical field
The invention belongs to pitch preparation field, relate in particular to a kind of emulsification coal-tar pitch.
Background technology
Along with Chinese society, expanding economy, enter high-speed development period from " 95 " road construction later, heavy road construction and maintenance task have determined that domestic road bitumen market is by long-term supply and demand anxiety, China's oil asphaltic products. deficiency remains on a high position to the demand of Imported oil pitch, and asphalt price is by the fluctuation with the variation of International Petroleum Price.Along with the adjustment of China's economic structure as Coal Chemical Industry product coal-tar pitch in supply exceed demand state, the coal-tar pitch that script is used for burning is for road construction, can solve the problem of highway in China coal-tar pitch anxiety, also can solve the problem of outlet of Coal Chemical Industry product, also solve the coal-tar pitch harm that environment is brought of burning, therefore, coal-tar pitch is imperative for road construction, have not yet to see the domestic pair report of coal-tar pitch emulsification that has.
Because coal-tar pitch carbon content is high, medium temperature coal pitch free carbon content is higher, thereby glue core is large especially, and dispersion medium and to play the content of resinous substances of dissemination few comparatively speaking, therefore compared with petroleum pitch, coal-tar pitch is difficult for emulsification.
Summary of the invention
The object of the present invention is to provide a kind of emulsification coal-tar pitch, be intended to solve the problem that coal-tar pitch is difficult for emulsification.
The present invention is achieved in that a kind of emulsification coal-tar pitch, and the various raw-material ratios of described emulsification coal-tar pitch are:
Another object of the present invention is to provide a kind of emulsification coal-tar pitch, described emulsification coal-tar pitch preparation method comprises the following steps: in petroleum pitch emulsifying agent, add wilkinite, after mixing with water, obtain emulsion, utilize coal-tar pitch and emulsion to prepare emulsification coal-tar pitch.
Concrete preparation process and method are:
By the coal-tar pitch emulsifying agent of petroleum pitch emulsifying agent and wilkinite mixture Cheng Xin;
More than water is heated to 60 degree;
Water is become to emulsion with coal-tar pitch emulsifying agent mixture;
Coal-tar pitch is heated to 115 degree left and right, becomes liquid;
By liquid coal pitch and emulsion mixture, make emulsification coal-tar pitch.
Emulsification coal-tar pitch of the present invention, utilizes petroleum pitch emulsifying agent to add and joins bentonitic method, makes coal-tar pitch obtain emulsification, has solved the stable problem after coal-tar pitch emulsification and emulsification.
Accompanying drawing explanation
Fig. 1 is the emulsification coal-tar pitch preparation method's that provides of the embodiment of the present invention schema.

In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The present invention is achieved in that a kind of emulsification coal-tar pitch comprises the following steps: in petroleum pitch emulsifying agent, add wilkinite, after mixing, obtain emulsion with water, utilize coal-tar pitch and emulsion to prepare emulsification coal-tar pitch.
The present invention prepares the various raw-material ratios of emulsification coal-tar pitch:
(coal-tar pitch) 500:(water) 500:(petroleum pitch emulsifying agent) 3:(wilkinite) 1
Emulsification coal-tar pitch preparation process provided by the invention and method are:
1, by the coal-tar pitch emulsifying agent of petroleum pitch emulsifying agent and wilkinite mixture Cheng Xin;
2, more than water is heated to 60 degree;
3, water is become to emulsion (also claiming soap lye) with coal-tar pitch emulsifying agent mixture;
4, coal-tar pitch is heated to 115 degree left and right, becomes liquid;
5, by liquid coal pitch and emulsion mixture, make emulsification coal-tar pitch.
Emulsification coal-tar pitch preparation method provided by the invention, utilizes petroleum pitch emulsifying agent to add and joins bentonitic method, makes coal-tar pitch obtain emulsification, has solved the stable problem after coal-tar pitch emulsification and emulsification.
Table 1 is emulsified bitumen testing data.
Emulsified bitumen testing data
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various modifications that performing creative labour can make or distortion still within protection scope of the present invention.
