Problems solved by technology

[0003] However, the rock wool material is mainly made of inorganic materials by spinning. When it is used as a fiber to strengthen the resin, the compatibility between the rock wool fiber and the resin is poor; Compatibility between fibers and resin matrix and fillers, but the glue sprayed on the rock wool material is often an organic resin substance, which is easy to fall off from the fiber and lose the modification effect

Abstract

Belonging to the field of mineral fiber preparation, the invention particularly relates to a preparation method of an adhesive sprayed rockwool. Before adhesive spraying, a mixed aqueous solution of copper salt and yttrium nitrate is employed for pretreatment of rockwool fiber to promote the combination fastness of an adhesive layer and fiber after adhesive spraying, thus ensuring the dispersion compatibility of the adhesive sprayed rockwool in an organic resin system.

Description

technical field [0001] The invention belongs to the field of preparation of mineral fibers, in particular to a preparation method of glue-sprayed rock wool. Background technique [0002] The glue-sprayed rock wool material is prepared from basalt through crushing, high-temperature melting, spinning, gluing, chopping, baking, and loosening. It has a highly fibrillated structure and a strong ability to capture fine particles. Fine particles, the ability to inhibit loss; and moderate hardness, good stain resistance, low moisture sensitivity, high service temperature, no storage environment restrictions, better processing performance than aramid fibers and close to Performance, its price is only 1 / 20 of aramid fiber. [0003] However, the rock wool material is mainly made of inorganic materials by spinning. When it is used as a fiber to strengthen the resin, the compatibility between the rock wool fiber and the resin is poor; Compatibility between fibers and resin matrix and f...
