Flame retardant acrylic plate and manufacturing method
TLDR
In this paper, a flame retardant acrylic plate and a manufacturing method thereof are provided to minimize the discharge of harmful materials in the combustion through excellent fire retardant characteristics and flame resistance without the use of a halogen-based flame retardants.Abstract:
PURPOSE: A flame retardant acrylic plate and a manufacturing method thereof are provided to minimize the discharge of harmful materials in the combustion through excellent fire retardant characteristics and flame resistance without the use of a halogen-based flame retardant CONSTITUTION: A method for manufacturing a flame retardant acrylic plate comprises the steps of: mixing methyl methacrylate(MMA), phosphate-based flame retardant, sodium-based montmorillonite(Na-MMT), and ethyleneglycoldimethacrylate(EGDMA) and polymerizing the mixture at 70 ~ 120°C for 1 ~ 3 hours; curing the polymerizate in a mold for 1 ~ 5 hours and molding the polymerizate in a plate shape The phosphate-based flame retardant is at least one of monoammonium phosphate, ammonium polyphosphate, triaryl phosphate, tricresil phosphate, triethyl phosphate, triphenyl phosphateread more

Choi Heon Sik,Kim Ji Eon +1 more
TL;DR: In this paper, a method for producing a flame-retardant acrylic resin composition, which comprises the following steps: mixing a phosphorus-based compound-containing first flame retardant, an acrylamide-based compounds-containing second flame-protective, and a surfactant having acryl group and a phosphate group, and then stirring the same so as to produce a flame retardant mixture.
