Abstract

The invention discloses a special impregnating agent for basalt fiber and a preparation method thereof. The impregnating agent comprises 3-8% of water-soluble epoxy resin, 2-6% of a polyvinyl acetate emulsion, 0.5-1.0% of a coupling agent, 0.2-0.8% of an antistatic agent, 0.6-1.2% of a plasticizer, 0.08-0.20% of a pH regulator and the balance of water in terms of percentage by weight. The surface of basalt fiber in the basalt producing drawing process is coated directly with the impregnating agent for basalt fiber surface modification, prepared according to a rated weight ratio, and surface modification is carried out after drying, so that the impregnating agent is more convenient to use, and the aqueous solution of the impregnating agent has very good adhesion and film-forming property.

Description

Technical field: [0001] The invention relates to a reinforced fiber sizing agent and a preparation method thereof, belonging to the technical field of sizing agents. Background technique: [0002] Basalt fiber is a continuous fiber drawn at high speed by a platinum-rhodium alloy wire drawing bushing after melting basalt rock at 1450°C to 1500°C, and its strength is equivalent to that of high-strength S glass fiber. Basalt fiber has good mechanical strength, high temperature resistance, chemical corrosion resistance, heat insulation, sound insulation, good wave transmission and absorption performance and environmental protection performance. One of the high performance fibers. [0003] In the fiber drawing process, a surface treatment agent mainly composed of organic emulsion is coated on the surface of the fiber, that is, the fiber sizing agent. The use of sizing agent can effectively change the processing performance of inorganic fibers; in the molding process of inorgani...
