Emulsified coal tar pitch

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 [0001] The invention belongs to the field of asphalt preparation, in particular to an emulsified coal tar pitch. Background technique [0002] With the development of our country's society and economy, road construction has entered a period of rapid development since the "Ninth Five-Year Plan". The heavy road construction and maintenance tasks have determined that the domestic road asphalt market will be in short supply and demand for a long time. The demand remains high, and the price of bitumen will fluctuate greatly with the change of international oil price. With the adjustment of my country's economic structure, coal tar pitch, a coal chemical product, is in a state of oversupply. Using coal tar pitch originally used for combustion in road construction can solve the problem of coal tar pitch shortage in my country's roads, and can also solve the problem of coal chemical industry. The problem of the outlet of the product also solves the harm caused by the...
