Abstract

The invention discloses a DN black golden board, which comprises a sound-insulation modified graphite polyphenyl board. Non-woven cloth is combined with the surface of the sound-insulation modified graphite polyphenyl board. The sound-insulation modified graphite polyphenyl board is prepared by a foaming-extrusion moulding technology and comprises following raw materials in parts by weight: 50 to70 parts of polystyrene resin particle, 8 to 15 parts of graphite particle, 15 to 35 parts of nano TiO2 modified natural vegetable rubber, and 8 to 12 parts of a foaming agent. Nano TiO2 is premixed and then evenly coated on the outer surface of natural vegetable rubber. The invention also relates to a processing method of the DN black golden board. The DN black golden board is light, compact, andfire retardant, and has a thermal-insulation property and a soundproof property, the installation strength is high; at the same time, the processing method is simple and environmentally friendly anddoes not need any organic solvent; massive production is easy to perform; and the DK black golden board is a very good thermal-insulation soundproof material.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a DN black gold board, and also relates to a processing method of the DN black gold board, which is an excellent sound insulation and thermal insulation material. Background technique [0002] With the improvement of people's requirements for green and energy-saving living environment, various noises have brought a huge threat to residents living in cities, especially residential residents in complex environments are most affected. How to solve the impact of urban noise and strengthen the anti-noise ability of residential buildings has become an important problem facing the central residential area. [0003] However, the current conventional green ecological residential quarters only focus on greening, waterscape and other hard landscapes as the focus of environmental construction, and pay less attention to the construction of physical environments such as sound, lig...
