Abstract

The invention discloses a sound-insulation material and a preparation method thereof. The material is prepared from, by weight, 50-60 parts of phenyl phenol formaldehyde resin, 25-35 parts of expanded vermiculite, 15-25 parts of montmorillonite, 10-20 parts of 8-10% waterborne polyurethane emulsion, 6-8 parts of polystyrene foamed plastic, 10-14 parts of polymethyl methacrylate, 2-4 parts of vinyl triethoxysilane, 2-4 parts of nano silicon dioxide, 1-3 parts of nano carbon black, 1-3 parts of magnesite, 0.6-0.8 part of antioxidant 168 and 5-7 parts of a mixture of barium stearate and cobalt naphtenate, wherein the weight ratio of barium stearate to cobalt naphtenate is (4-6):1. The sound-insulation material is high in sound-insulation coefficient and good in sound-insulation performance, sound-insulation performance is related to the weight ratio of barium stearate to cobalt naphtenate, and when the weight ratio of barium stearate to cobalt naphtenate is (4-6):1, the sound-insulation performance is optimal.

Description

Technical field [0001] The invention belongs to the field of building materials, and specifically relates to a sound insulation material and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy and the continuous acceleration of the process of urbanization, noise pollution, water pollution, and air pollution are collectively called the three major pollution. In order to effectively cut off noise, people's usual solution is to use sound insulation materials. The existing sound insulation materials are generally cement concrete, glass panels, etc., and the effect of reducing noise is achieved by using these materials. However, the effect is not very satisfactory, so the usual solution is to increase the thickness of the sound insulation material. The problem caused by this is that the quality of the sound insulation material is too heavy, the cost is too high, and the installation process is very inconvenient. Summary of ...
