Abstract

The invention relates to a multi-layer three-dimensional fiber composite GRC hollow thermal insulation board and a preparation method thereof, specifically a high-strength exterior wall panel with a decorative effect and a thermal insulation function; it can not only ensure the decorative effect of the decorative exterior wall At the same time, combined with the respective characteristics of multi-layer three-dimensional fiber mortar layer and thermal insulation mortar layer to make high-strength and thermal insulation exterior wall panels, it can overcome the shortcomings of existing hollow panels with low strength and poor thermal insulation effect, and improve the use of GRC curtain wall panels. The invention also discloses a method for preparing a multi-layer three-dimensional fiber composite GRC hollow insulation board. The invention has a simple process, high economic and environmental benefits, and belongs to resource utilization with high added value.

Description

technical field [0001] The invention relates to a decorative integrated composite GRC hollow board. Specifically, high-strength, heat-insulating and light-weight GRC composite panels are obtained by compounding three-dimensional fibers, thermal insulation layers, and hollow structural layers. While ensuring the decorative performance of GRC exterior wall panels, its various performances are significantly improved, and it is suitable for building roofs, building curtain walls, wall decoration and other fields. Background technique [0002] In my country, building energy consumption accounts for more than 36% of the total energy consumption of the whole society. In some parts of the country, condensation often occurs on the corners of the east and west gables and top rooms. The heat transfer coefficient of this external wall is 1.57 (w / m2 k), while the external wall heat transfer coefficient of developed countries with similar climatic conditions is only 0.35 (w / m2 k). Many ...
