Lightweight high-strength microcirculation composite external heat preservation fireproof non-dismantling formwork and preparation method thereof

Abstract

The invention relates to the technical field of insulation boards for buildings, and provides a lightweight high-strength microcirculation composite external heat preservation fireproof non-dismantling formwork and a preparation method thereof. The formwork sequentially comprises an inner reinforcing layer, a modified heat preservation layer, a bonding layer, a fireproof transition layer and an outer reinforcing layer from inside to outside; the modified heat preservation layer is provided with a temperature and humidity adjusting hole transversely penetrating through the heat preservation layer, and the hole is filled with a rock mud material; and the modified heat preservation layer is a natural mineral nanofiber modified extruded sheet. The lightweight high-strength microcirculation composite external heat preservation fireproof non-dismantling formwork is good in heat preservation performance, adjustment of indoor temperature, humidity and oxygen content can be achieved, the requirements of low carbon and environmental protection are met, the plate is good in compression resistance and shear resistance, excellent in stability, small in volume weight and high in fireproof grade, and the safety of a building can be improved.

Problems solved by technology

Most of the core insulation layers of this structure system are molded polystyrene foam (EPS), extruded board (XPS), sprayed or rigid polyurethane (polyurethane, PUR for short), etc., and these materials themselves have water vapor resistance. When the temperature in the living room rises, the saturated water vapor cannot migrate outward, causing the indoor air to stay for a long time, and the oxygen content of the air ages to decrease. In the north, the indoor thermal comfort is poor in winter, and in the south, the air conditioner consumes a lot of energy in summer , cannot meet the health indicators "humidity, temperature, and oxygen content" necessary for human living, and make the "old, young and infirm" feel uncomfortable-this kind of sick building has become an urgent problem that must be changed for human settlements.

Moreover, the structure of the current integrated formwork for external thermal insulation without dismantling is single and simple, and does not consider the three major evaluation indicators of human living environment comfort "humidity, temperature, and oxygen content" and the needs of energy saving, low carbon and environmental protection
