Embodiment 1

[0026] A basalt fiber epoxy type sizing agent consists of the following components by weight percentage:

[0027]

[0028] Preparation steps:

[0029] a. Slowly add polyvinyl alcohol in cold water at about 20 degrees Celsius to make it fully swell, disperse and escape volatile substances in cold water. When the temperature reaches about 95 degrees Celsius, it will accelerate the dissolution, and keep it warm for 2 to 2.5 hours for later use.

[0030] b. Add the water-soluble epoxy resin into the water and stir evenly, the water temperature is 50-70 degrees; the amount of water is 5-10 times the weight of the water-soluble epoxy resin for later use;

[0031] c. Add a pH regulator in deionized water to adjust the pH value to 4-6, add aminosilane coupling agent under stirring, and continue stirring for 25-35 minutes until the aqueous solution is clear and transparent; the amount of water accounts for 10% of the total weight of the wetting agent 1 / 20;

Abstract

The invention discloses a special impregnating compound for basalt fibers and a preparation method of the impregnating compound. The impregnating compound comprises raw materials in percentage by weight as follows: 2%-10% of water-soluble epoxy resin, 1%-8% of polyvinyl alcohol, 0.5%-1.0% of a coupling agent, 0.2%-0.8% of an antistatic agent, 0.08%-0.25% of a pH regulating agent and the balance of deionized water. The impregnating compound for surface modification of the basalt fibers is prepared in the rated weight proportion and directly coats surfaces of the basalt fibers during basalt production drawing, surface modification is completed after drying, and the impregnating compound is more convenient to use and has the 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...
