Abstract

The invention discloses a thermal insulation material for buildings and a preparation method of the thermal insulation material. The preparation method comprises the following steps: mixing tristyrylphenol ethoxylate, ethanol, alumina fiber and aramid fiber, and performing curing at 50-70 DEG C for 1-2 hours to obtain a modified fiber mixture; mixing polystyrene particles, a modified fiber mixture, phenolic resin, aluminum borate, kaolin, silica, white carbon black, water glass and water to obtain slurry M; adding a foaming agent and a stabilizing agent to the slurry M, and continuously introducing nitrogen to obtain slurry N; adding the slurry N to a mold, and performing hot pressing and molding to obtain a green body; heating and puffing the green body under the microwave condition to obtain the thermal insulation material for the buildings. The problems that heat dissipation efficiency is low and harmful gas is easily released by heating due to lower mechanical strength and higher thermal conductivity of current existing thermal insulation materials are solved.

Description

technical field [0001] The invention relates to thermal insulation materials, in particular to a thermal insulation material for buildings and a preparation method thereof. Background technique [0002] Thermal insulation of various thermal equipment and buildings is an important measure for energy saving. Thermal insulation materials are the material basis for energy conservation. Thermal insulation materials with excellent performance and good thermal insulation technology can often achieve twice the result with half the effort in industrial thermal insulation. At present, the existing thermal insulation materials have problems such as low mechanical strength and high thermal conductivity, which lead to low heat dissipation efficiency and easy release of harmful gases when heated. [0003] Therefore, it is an urgent problem to be solved by the present invention to provide a kind of high mechanical strength, low thermal conductivity, which can adapt to various complex buil...
