Abstract

The invention discloses a flame retardant polystyrene foamed hard wood-imitating material and a preparation method thereof. The hard wood-imitating material comprises, by weight, 50-70 parts of recovered polystyrene, 55-75 parts of high impact polystyrene, 35-45 parts of flame retardant masterbatch for a core layer, 30-40 parts of special flame retardant masterbatch for a surface layer, 0.5-0.9 parts of a foaming agent, 1-4 parts of a flexibilizer, 0.1-0.5 parts of a plasticizer, and 0.5-0.9 parts of a coloring agent. The flame retardant polystyrene foamed hard wood-imitating material of the present invention has high intensity flame retardation, is a hard foamed wood-imitating material with certain toughness and low density, and simultaneously has the advantages of fireproofing, waterproofing, oil resistance, insect prevention, mildew resistance, weatherproofing, light weight and the like.

Description

technical field [0001] The technology relates to a polymer wood-like composition, in particular to a polystyrene low-foaming rigid flame-retardant wood-like material and a preparation method thereof. Background technique [0002] At present, polystyrene low-foaming hard imitation wood materials are widely used in the field of medium and high-end home decoration crafts and home decoration building materials such as picture frames, mirror frames, and photo frames. However, the flammability of polystyrene (referred to as PS, the same below) limits the promotion and application of its low-foaming hard products in building materials, especially in the field of automotive interiors. [0003] At present, flame retardant PS materials are mostly concentrated in high expansion ratio expandable polystyrene (EPS), extruded polystyrene (XPS) thermal insulation materials and non-foaming PS solid materials, but various flame retardant PS The material has the following deficiencies: [00...
