Abstract

The invention belongs to the technical field of inorganic fiber modification, and relates to basalt fiber surface modification, in particular to a preparation method of a basalt fiber surface modifiedcoating. The method includes the steps: firstly, adding silane coupling agents, surface active agent solution, polyacrylamide solution and 1 / 3 water-borne epoxy resins into an appropriate amount of nano-silicon dioxide dispersion liquid, and performing reflux reaction; secondly, dropping residual water-borne epoxy resins and initiating agent solution when heating, and performing continuous reaction of an alkaline system to obtain the basalt fiber surface modified coating. The invention further discloses an application of the prepared basalt fiber surface modified coating. Basalt fiber surfacegroups are activated by strong H2SO4 / H2O2 mixed solution, etched by hydrochloric acid, soaked into the coating to graft and dried to constant weight. Prepared coating emulsion does not contain any organic solvents and is green, environmentally friendly, convenient and simple in operation technique, high in applicability and stable in performance and can be applied to the field of microbial film carrier materials, basalt fibers can be rapidly and effectively modified, and the surface roughness of the basalt fibers is obviously increased.

Description

technical field

[0001] The invention belongs to the technical field of inorganic fiber modification, and relates to a method for surface modification of basalt fiber, in particular to a preparation method and application of a basalt fiber surface modification coating. Background technique

[0002] At present, the shortage of water resources and water pollution coexist in my country, and the pollution of surface water is still serious. It is urgent to protect water resources, improve the water environment, and improve the efficiency of sewage / wastewater treatment. The conventional process of sewage / wastewater treatment covers physical, chemical and biological methods, and most of the sewage / wastewater treatment in my country is mainly based on biological methods. Among the processes of biological treatment of sewage / wastewater, the biofilm process is the most widely used technology. Biofilm wastewater treatment technology is a technology that fixes microorganisms on a carrie...
