Abstract

The invention discloses a noise-reducing and fireproof external wall panel. The external wall panel comprises a base layer, a noise-reducing and fireproof layer, a flow guide plate layer, an abrasion-resistant layer and a decoration coating which are arranged sequentially from inside to outside; a preparation method of the noise-reducing and fireproof layer comprises steps as follows: a phosphonitrilic chloride trimer is heated, kept at the temperature, cooled to the room temperature and washed, and polydichlorophosphazene is obtained; polydichlorophosphazene is added to tetrahydrofuran, hydroquinone is dropwise added, then reflux heating, distillation, washing and vacuum drying are performed, and a material a is obtained; after the material a and poly-1,4-butylene adipate glycol are evenly mixed, 1,6-hexamethylene diisocyanate is added, dry nitrogen is introduced for protection, and a material b is obtained through heating, temperature keeping and cooling; diethylene glycol, pentaerythritol, bismuth laurate, a foaming agent, a blowing promoter, bentonite, palygorskite, expanded perlite, glass fibers, jute fibers, magnesium hydroxide, an anti-aging agent and acetone are evenly mixed, the surface of the base layer is coated with the mixture, and then the noise-reducing and fireproof layer is obtained through heating and temperature keeping.

Description

technical field [0001] The invention relates to the technical field of wallboards, in particular to a sound-absorbing and fireproof exterior wallboard. 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 in the background technology, the present invention proposes a sound-absorbing and fire-resistant exterior wall ...
