Abstract

The invention discloses a softening modifier for inorganic fibers and a preparation method thereof, comprising the following steps: step S10, preparing dispersant A; step S20, preparing softener B; step S30, mixing dispersant A and softener B is packaged separately to obtain the softening modifier for inorganic fibers. The softening modifier for inorganic fibers prepared by the present invention can significantly improve the dispersibility and softness of the inorganic fibers after the inorganic fibers are modified, and enhance the strength of the inorganic fibers so that they are not easy to break and increase the strength of the inorganic fibers. application range.

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...
