Background

The basalt fiber is a continuous fiber which is formed by taking natural basalt ore as a raw material, crushing, adding into a melting furnace, melting at a high temperature of 1450-1500 ℃, and drawing at a high speed through an alloy bushing, and is a fourth high and new technology fiber following carbon fiber, aramid fiber and ultra-high molecular weight polyethylene fiber.

The raw materials are low in price, natural and pollution-free, have no additive, and are the only green vitreous fiber products so far. Because of the excellent performance of basalt fiber, various composite materials with excellent performance can be prepared by taking the basalt fiber as a reinforcement, and are known as new materials in the 21 st century. The basalt fiber material has important use value in industry, is widely applied to the fields of traffic, bridges, textiles, fire protection, environmental protection, aerospace, automobile manufacturing, engineering plastics and the like, and can also be widely applied to the fields of energy conservation, heat insulation, civil and architectural engineering and military industry.

The common problems encountered in the composite preparation of basalt fiber with other materials such as asphalt and paint are poor interface effect between fiber and resin, poor wetting effect and easy delamination, which are caused by the high surface energy and large specific surface area of basalt fiber.
