Abstract

The invention discloses a soakage agent for basalt fibers and a preparation method of the soakage agent. The soakage agent is prepared from 2%-8% of water-soluble epoxy resin, 1%-5% of a polyester emulsion, 2%-4% of a vinyl resin 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%-0.25% of a pH regulator and the balance of deionized water. The soakage agent which is prepared in the rated weight ratio and used for surface modification of the basalt fibers can be directly applied to the surfaces of the basalt fibers in the production and drawing process of the basalt fibers, surface modification can be completed after drying, the soakage agent is more convenient to use, and an aqueous solution of the soakage agent has good adhesion and film-forming properties.

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...
