Abstract
A decorative board 5 includes: a prepreg 2 that includes a binder component including: at least one thermoplastic resin selected from a group consisting of acrylic resin having a glass-transition temperature Tg exceeding 0° C., vinyl chloride resin having a glass-transition temperature Tg exceeding 0° C., acrylic urethane, and aqueous polyurethane resin, and a thermosetting resin, a mixing ratio of the at least one thermoplastic resin to the thermosetting resin being 1:0-0.5 in solid content ratio, and an endothermic metal hydroxide; and a thermosetting resin impregnated decorative paper 1, wherein the prepreg and the thermosetting resin impregnated decorative paper are stacked and integrated.
Claims19
A decorative board comprising:
- a prepreg comprising:
- an inorganic fiber substrate;
- at least one thermoplastic resin selected from a group consisting of acrylic resin emulsion having a glass transition temperature Tg exceeding 0° C. and having an average particle diameter of 150-300 nm, and acrylic urethane;
- a thermosetting resin, a mixing ratio of the thermoplastic resin to the thermosetting resin being 1:0-0.5 in solid content ratio by weight;
- and
- an endothermic metal hydroxide;
- and
- a thermosetting resin impregnated decorative paper comprising:
- a thermosetting resin;
- and
- a decorative paper;
- wherein the prepreg and the thermosetting resin impregnated decorative paper are stacked and integrated.
A decorative board comprising:
- a melamine resin impregnated decorative paper obtained by impregnating a decorative paper weighing between 30-140 g/m2 with a melamine resin with an impregnation rate of 80% to 300%;
- a prepreg disposed next to the melamine resin impregnated decorative paper, the prepeg including:
- an acrylic resin emulsion having a glass transition temperature Tg exceeding 0° C. and having an average particle diameter of 150-300 nm;
- an endothermic metal hydroxide having an average particle diameter of 1-50 μm;
- a fiber substrate;
- and
- a silane coupling agent;
- and
- a resin impregnated balance paper disposed adjacent the prepeg, the resin impregnated balance paper obtained by impregnating a surface paper weighing between 18-40 g/m2 with a melamine resin with an impregnation rate of 260% to 320%.
A decorative board comprising, from a top to a bottom:
- a melanine resin impregnated decorative paper;
- a first prepreg layer including:
- a first thermoplastic resin formed from a first acrylic resin emulsion having a glass transition temperature Tg exceeding 0° C. and having an average particle diameter of 150-300 nm,
- a first endothermic metal hydroxide,
- a first fiber substrate,
- a first non-aqueous inorganic filler with an average particle diameter of 1-5 μm, and
- a first silane coupling agent with an impregnation rate of 700% to 1200%;
- a second prepreg layer including:
- a second thermoplastic resin,
- a second endothermic metal hydroxide,
- a second fiber substrate,
- a second non-aqueous inorganic filler, and
- a second silane coupling agent;
- and
- a melanine resin impregnated non-decorative paper weighing between 18 g/m2 and 40 g/m2 with an impregnation rate of 260% to 320%.
