Abstract

The invention discloses a flame-retardant coating for a guitar fibreboard and a preparation method thereof. The flame-retardant coating for the guitar fibreboard is prepared from 50 to 100 parts of epoxy resin, 30 to 60 parts of silicone acrylic emulsion, 20 to 40 parts of a polyurethane prepolymer, 20 to 40 parts of organic halogenated phosphate, 10 to 20 parts of tetrahydrofuran, 0 to 20 parts of polylactate ester, and 10 to 20 parts of SiO2. The flame-retardant coating for the guitar fibreboard provided by the invention has the advantages of being good in thermal barrier effect, and good inflame retardant effect.

Description

technical field [0001] The invention relates to a flame-retardant coating, in particular to a flame-retardant coating for guitar fiberboard and a preparation method thereof. Background technique [0002] Fiberboard is a wood-based panel made by interweaving lignocellulosic fibers and utilizing their inherent adhesive properties. Adhesives and / or additives can be applied during the manufacturing process. [0003] Fiberboard, also known as density board, is a wood-based panel made of wood fiber or other vegetable fiber and applied with urea-formaldehyde epoxy resin or other suitable adhesives. Adhesives and / or additives can be applied during the manufacturing process. Fiberboard has the advantages of uniform material, small vertical and horizontal strength difference, not easy to crack, etc., and has a wide range of uses. It takes about 2.5-3 cubic meters of wood to make 1 cubic meter of fiberboard, which can replace 3 cubic meters of sawn timber or 5 cubic meters of logs. ...
