Problems solved by technology

However, in the prior art, it is impossible to ensure that these glass fibers are in good contact with the gypsum. The existence of these fibers with poor interface contact will increase the void channels in the gypsum body after hardening, increase the water absorption of gypsum, and reduce the moisture-proof performance of gypsum; At the same time, the existence of pores is not conducive to the enhancement of the strength of the entire GRG plate, which needs to be further improved

Abstract

The invention discloses a composite-glass-fiber-reinforced gypsum board and a manufacturing method thereof. The manufacturing method comprises the following steps: (1) preparing glass fibers; (2) pretreating the glass fibers; (3) weighing graphene quantum dots, and preparing a 0.1-1 mg / ml dispersion solution, wherein the solvent is water, acetone or dimethylsulfoxide; carrying out ultrasonic agitation on 80-100ml of the graphene quantum dot dispersion solution, adding the pretreated glass fibers, carrying out ultrasonic agitation at half of the speed, and impregnating for 30-60 minutes; taking out the glass fibers, cleaning, and drying for later use; (4) preparing graphene-modified composite glass fibers; and (5) preparing the composite-glass-fiber-reinforced gypsum board. According to the composite-glass-fiber-reinforced gypsum board, the strength of the glass-fiber-reinforced gypsum board is effectively improved, and the water absorptivity is lowered.

Description

technical field [0001] The invention relates to a composite glass fiber reinforced gypsum board and a manufacturing method thereof. Background technique [0002] Glass fiber (original name in English: glass fiber or fiberglass) is an inorganic non-metallic material with excellent performance. Brittle, poor wear resistance. It is generally made of glass balls or waste glass through high-temperature melting, wire drawing, winding, weaving and other processes. The diameter of its single filament is several microns to more than 20 microns, which is equivalent to a hair 1 / 20~1 / 5 of silk, and each bundle of fiber precursors is composed of hundreds or even thousands of single filaments. [0003] Graphene, as an allotrope of carbon, is a single-layer two-dimensional crystal material with a honeycomb structure formed by the hybridization of carbon atoms according to sp2 orbitals. Graphene has good mechanical properties and chemical stability, which will also be used in composite ma...
