Abstract

The invention discloses a softening modifier for inorganic fiber and a preparation method thereof. The method comprises the following steps that S10, a dispersant A is prepared; S20, a softener B is prepared; S30, the dispersant A and the softener B are separately packaged to obtain the softening modifier for the inorganic fiber. After the softening modifier for the inorganic fiber is used for modifying the inorganic fiber, the dispersibility and softness of the inorganic fiber can be remarkably improved, the strength of the inorganic fiber is enhanced, the inorganic fiber is not likely to break, and the application range of the inorganic fiber is enlarged.

Description

technical field [0001] The invention relates to the technical field of modifiers, in particular to a softening modifier for inorganic fibers and a preparation method thereof. Background technique [0002] Inorganic fiber is a chemical fiber made of minerals, the main varieties are glass fiber, quartz glass fiber, boron fiber, ceramic fiber, metal fiber and so on. Inorganic fibers have high rigidity and strength, good dimensional stability, good thermal conductivity, and low price, and can be widely used in wear-resistant materials, fiber additives for rubber and plastic materials, asphalt fiber stabilizers, fireproof and thermal insulation coatings for VIP boards, and special paper industries. However, inorganic fibers are brittle, strong, and have few polar groups on the surface, so it is difficult to combine with organic fibers. Adding too much will greatly reduce the strength of the material. Therefore, it is necessary to modify and soften the inorganic fiber. By purpose...
