Abstract

The invention discloses a preparation method of a flame-retardant insulating sound-isolating panel and belongs to the technical field of panel preparation. A primary material polyvinyl chloride resin of the sound-isolating panel is crosslinked with epoxidized soybean oil at a high temperature, a three-dimensional netty microporous structure is formed in the polyvinyl chloride resin, and basalt fibers which are soaked and etched by acetic acid are coarse and porous in surface, so that the heat conductivity coefficient of the sound-isolating panel is reduced; multiple reflection of sound waves is facilitated due to the coarse surface of the basalt fibers, so that the sound wave energy is consumed; moreover, friction generated by sound wave vibration will release heat energy; after the crosslinking reaction with a silane crosslinking agent, the binding force of the basalt fibers and a resin matrix is enhanced; silicon dioxide and a carbon chain framework of the resin matrix are bridged; part of aluminum oxide in the basalt fibers treated by alkali is converted into aluminum hydroxide, the temperature of the combustion part is reduced by means of endothermic decomposition at a high temperature, and heat is favorably dissipated at the high temperature as a result of the porous structure of the sound-isolating panel, so that the purpose of flame retardance is achieved.

Description

technical field [0001] The invention discloses a preparation method of a flame-retardant thermal insulation board and belongs to the technical field of board preparation. Background technique [0002] The sound insulation board is a plate that acts on the sound insulation effect. There are sound insulation of buildings and sound insulation of structures. Not all frequencies of sound can be blocked by the sound insulation board. Objects have a natural resonance frequency, and the sound insulation effect of the sound insulation board is significantly reduced when the sound is close to the resonance frequency of the object. [0003] The sound insulation board has the difference between air-proof sound and vibration sound. Air sound insulation panels are panels that block the sound that travels in the air. Vibration sound insulation panels are panels and systems that block the sound that propagates in rigid components. General objects have sound insulation effect, but we onl...
