Abstract

The invention discloses a basalt fiber impregnating compound and a preparation method thereof, belongs to the field of functional materials, and aims at solving the problem of lack of related public reports for the basalt fiber impregnating compound at present. The basalt fiber impregnating compound is prepared from the following raw materials in parts by weight: 3-10 parts of a silane coupling agent, 20-60 parts of water-soluble epoxy resin, 400-1000 parts of water, 1-3 parts of organic acid, 40-120 parts of absolute ethyl alcohol, 10-25 parts of glucomannan, 0.5-1.5 parts of an antistatic agent and 3-10 parts of a wetting agent. The impregnating compound has strong binding force with the fiber surface of basalt fiber, has good permeability, and can be used for infiltration modification of basalt; by adopting the impregnating compound, the plasticity, the tensile property and the breaking strength of the basalt fiber can be improved, the bundling property of the basalt fiber is improved, and subsequent processing is facilitated; the basalt fiber treated by the impregnating compound has good hydrophilicity, antistatic property, tensile strength and breaking strength.

Description

technical field [0001] The application relates to the field of materials, especially the field of functional materials, specifically a basalt fiber sizing agent and a preparation method thereof. Background technique [0002] Basalt fiber is an inorganic environmental protection, green high-performance fiber material. It is made of natural basalt rock as the main raw material, which is prepared by wire drawing after melting at high temperature. In the preparation process of basalt, it produces less waste and has less environmental pollution. The prepared product can be directly degraded in the environment after being discarded, without any harm, and meets the requirements of green environmental protection. At the same time, basalt fiber has the characteristics of good chemical stability, strong corrosion resistance, high temperature resistance, electrical insulation, large elastic modulus, and high tensile strength. It has been widely used in construction, transportation, pet...
