Inorfil softening intensifier and preparation thereof

Abstract

The invention relates to an inorganic fiber softening reinforcing agent and a preparation method thereof. The method is to lead H2O2, polyvinyl alcohol and potassium hydroxide to react for 2 to 4 hours at a temperature between 50 and 60 DEG C, adds an etherifying agent after the reaction to react for 4 to 8 hours at a temperature between 50 and 70 DEG C, and regulates the pH value of the solution to 7 to 8 so as to obtain the inorganic fiber softening reinforcing agent. The softening reinforcing agent is applicable to various inorganic fiber materials produced by physical or hot melt method, including basalt fibers, aedelforsite fibers, meerschaum fibers, gypsum fibers, flyash fibers and glass fibers. The softening reinforcing agent can improve the softness and strength of inorganic fibers, improve the defect of easy fracture of the inorganic fibers in processes of pulping, dispersing and transporting, change the charge property of the inorganic fiber surface, reinforce the bonding force of the inorganic fibers and plant fibers, and greatly improve application performance of the inorganic fibers in making paper, insulating wool boards and the like by wet method.

Description

technical field

[0001] The invention belongs to the field of chemical industry, and in particular relates to an inorganic fiber softening enhancer and a preparation method thereof. Background technique

[0002] With the development of my country's economy and the improvement of people's living standards, the demand for various papers is also increasing day by day. The leading raw material for papermaking in the world is wood, and my country is a country with a serious shortage of wood, so a large amount of wood pulp is imported every year to alleviate the contradiction between supply and demand. This situation forces people to seek and develop new papermaking raw materials. Inorganic mineral fiber is a new type of papermaking material between short plant fibers and traditional fillers (calcium carbonate, talcum powder), which includes various inorganic fiber materials produced by physical treatment or hot-melt methods, such as basalt fiber, Wollastonite fiber, fly ash fiber...
