Indoor thermal-insulated and sound-insulated plate and preparation method thereof

Abstract

The invention provides an indoor thermal-insulated and sound-insulated plate and a preparation method thereof. The thermal-insulated and sound-insulated plate is formed by binding a cork plate and a fixed plate through a binding agent, and the cork plate is formed by fumigating and compressing granulated cork which is formed by grinding cork bark. The indoor thermal-insulated and sound-insulated plate is composed of the cork plate and the fixed plate in an adhesive mode, the cork plate provides high-efficiency thermal-insulated, sound-insulated and sound-absorbed performance, the fixed plate provides a supporting effect, and a mature decorative plate in the present market can be selected as texture of the fixed plate; the thermal-insulated and sound-insulated plate combined by the cork plate and the fixed plate can be directly installed and applied to the wall body surface or ceiling inside a house after leaving a factory, one step is only needed, and a thermal-insulated and sound-insulated protective layer is formed; compared with construction installation of an existing sound-insulated plate or a thermal-insulated plate, a sound-insulated felt, a sound-absorbing cotton, a shock pad and coating materials are not needed to be used, thus the cost of construction materials is reduced, and the efficiency of a construction period is improved; and the cost of manpower and materials is saved.

Description

technical field [0001] The invention relates to the technical field of interior decoration boards, in particular to an indoor heat and sound insulation board and a preparation method thereof. Background technique [0002] The products on the existing interior decoration panel market are divided by function into two categories: sound insulation panels and heat insulation panels. At present, the thermal conductivity of heat insulation boards on the market is mostly between 0.022~0.080W / (m K), while the thermal conductivity of most sound insulation panels is between 0.070~0.160W / (m K). Decorative panels that combine excellent sound and heat insulation are rare. In interior decoration, if you need to install sound insulation panels and heat insulation panels as interlayer materials at the same time, you need to consider not only the fixed installation of the two different types of panels, but also the stability of materials such as thermal expansion and cold contraction of the ...
