Abstract

The invention discloses an exterior wall panel with excellent sound-absorbing and fire-proof performance, which comprises a base layer, a sound-absorbing fireproof layer, a plastering mortar layer, a waterproof layer, a decorative coating and a wear-resistant layer; the preparation method of the sound-absorbing fireproof layer is as follows: hydroquinone, Potassium hydroxide and toluene are mixed evenly, and then a toluene solution containing hexachlorocyclotriphosphazene is added dropwise, heated up, kept warm, washed with an alkali solution to obtain an organic phase, then the organic phase is distilled under reduced pressure, dried in vacuum, and recrystallized to obtain material a ; Mix material a and polytetrahydrofuran ether glycol evenly, then add trimethyl-1,6-hexamethylene diisocyanate, fill with dry nitrogen for protection, heat up, keep warm, and cool down to obtain material b; Add trimethylpentanediol, glycerin, bismuth neodecanoate, foaming agent, foaming aid, expanded perlite, palygorskite, diatomaceous earth, glass fiber, flax fiber, zinc borate hydrate, anti-aging agent and Acetone is mixed evenly, coated on the surface of the base layer, then heated up, and kept warm to obtain a sound-absorbing and fire-proof layer.

Description

technical field [0001] The invention relates to the technical field of exterior wall panels, in particular to an exterior wall panel with excellent sound-absorbing and fire-proof performance. Background technique [0002] Since the industrial revolution, the creation and use of various mechanical equipment has brought prosperity and progress to human beings, but at the same time it has also produced more and more noise. Noise can not only cause hearing damage, but also induce a variety of cancer-causing and fatal diseases, and also interfere with people's life and work. In order to reduce the harm of noise to the human body, external wall panels are often added to the outer walls of buildings to reduce indoor noise. However, the fire performance of external wall panels is poor, which cannot guarantee the safety of people and property. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes an...
