Special nano-modified impregnating compound for basalt continuous fiber and preparation method of special nano-modified impregnating compound

Abstract

The invention provides a special nano-modified impregnating compound for basalt continuous fiber and a preparation method of the special nano-modified impregnating compound. The preparation method comprises specific operation steps as follows: (1), citric acid is added to a deionized aqueous solution, the PH (potential of hydrogen) value of a citric acid aqueous solution is adjusted to range from 3 to 4, the mixture is stirred at a high speed, a silane coupling agent is slowly and dropwise added, the mixture is stirred until the silane coupling agent is completely hydrolyzed, and a clear and transparent hydrolyzed coupling agent is obtained; (2), organosilicone-modified acrylic ester and a polyester resin emulsion are diluted by 10-20 times with deionized water respectively and then are mixed and uniformly stirred, and a diluted film forming agent is obtained, monodispersed nano-silica and titanium dioxide particles are added, the mixture is heated, stirred and cooled at the room temperature, and the film forming agent containing nano particles is obtained; (3), fatty acid amide acetate, aliphatic ester sulfate and a quaternary ammonium salt cationic antistatic agent are added to deionized water, the PH value of the solution is adjusted, the hydrolyzed coupling agent and the film forming agent containing the nano particles are added respectively, the mixture is stirred uniformly and left to stand to be defoamed, and the special nano-modified impregnating compound for the basalt continuous fiber is obtained.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, and in particular relates to a special sizing agent for nano-modified basalt continuous fibers and a preparation method thereof. Background technique: [0002] Basalt fiber is a new type of inorganic fiber. The unique composition of basalt ore and the combination of fiber structure endow the fiber with high strength, high modulus, high temperature corrosion resistance, and the fiber can be directly returned to nature without causing environmental pollution. It is green and environmentally friendly. At present, my country has mastered the preparation technology of basalt fiber, but the research and development of sizing agent for basalt fiber is still less, and the sizing agent of glass fiber is mostly used for basalt fiber. [0003] However, as we all know, the formulation of the sizing agent should be adjusted according to the type and use of the fiber. The sizing agent for glass fiber...
