Problems solved by technology

However, in the prior art, there is no guarantee that these glass fibers are in good contact with 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 rate 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 board, which needs to be further improved; the antibacterial performance of existing gypsum boards also needs to be further improved

Abstract

The invention discloses an antibacterial glass-fiber-reinforced gypsum board and a manufacture method thereof. The manufacture method comprises the following steps: (1) preparation of glass fiber; (2) pre-treatment of glass fiber; (3) preparation of silver loading glass fiber; (4) coating with porous graphene; (5) preparation of silver and titanium dioxide loading antibacterial glass fiber; and (6) preparation of a composite glass-fiber-reinforced gypsum board. The strength of the glass-fiber-reinforced gypsum board is improved, the water absorption is reduced, and the glass-fiber-reinforced gypsum board has long-lasting antibacterial characteristics.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an antibacterial 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 properti...
