Abstract

The invention discloses a basalt fiber surface modification impregnating compound and a preparation method thereof, and belongs to a basalt fiber impregnating compound. The impregnating compound comprises the following components in percentage by weight: 0.2-0.6% of organic silane coupling agent, 0.05-0.3% of pH (potential of hydrogen) conditioning agent, 3.0-10.0% of polyvinyl acetate emulsion, 0.2-2.0% of polyurethane emulsion, 0.5-3.0% of water-borne epoxy resin film forming matter, 1.0-5.0% of polyolefin emulsion, 0.1-1.0% of organic silicon emulsion, 0.1-1.0% of antistatic agent and the balance of water. The basalt fiber surface modification impregnating compound prepared according to the rated mass ratio is directly coated on the surface of basalt fiber in the basalt producing and wiredrawing process, and the surface modification is finished after the basalt fiber surface modification impregnating compound is dried, thereby being convenient to use. Meanwhile, the preparation method for the basalt fiber surface modification impregnating compound, which is disclosed by the invention, is simple, is suitable for industrial production and is easy for popularizing.

Description

technical field [0001] The invention relates to a basalt wetting agent, more specifically, the invention mainly relates to a basalt fiber surface modification wetting agent and a preparation method thereof. Background technique [0002] With the development of my country's economy, the scale and speed of infrastructure construction are advancing by leaps and bounds. In the construction of transportation facilities, the amount of asphalt mixture used in highways, urban roads and other fields is increasing. As it tends to be larger, the requirements for asphalt pavement are getting higher and higher, and asphalt pavement under high temperature and complex stress and strain conditions needs to have better road performance. At present, one research and application direction to improve the road performance of asphalt mixture is to use fiber reinforced asphalt mixture. The fibers used mainly include lignin fiber, synthetic fiber, mineral fiber and continuous basalt fiber. Among th...
