Method for producing rigid foam polyurethane heat-insulation and decorative integrated plate

Abstract

The invention relates to a method for producing rigid foam polyurethane heat-insulation and decorative integrated plate. The method can be used for continuous production, production efficiency is high, large quantities of production cost and construction cost are saved, the plate is light in weight, high in flatness and fine in decorative effect, and can be optionally cut, requirements of a construction method for a heat-insulation and decorative integrated system can be met, and requirements of a construction method for a thin plastering system can also be met.

Description

technical field [0001] The invention relates to the field of energy-saving building materials, in particular to a production process of a hard foam polyurethane thermal insulation and decoration integrated board. Background technique [0002] Building energy consumption has reached 27.6% of the energy consumption of the whole society. Rigid polyurethane foam is considered to be the most ideal material to achieve 65% energy saving in buildings, and external wall insulation is the best way to realize new buildings, existing buildings and old city renovations. ; At present, there are mainly two types of systems for the external thermal insulation of rigid foam polyurethane panels, namely the thin plastering system and the integrated thermal insulation and decoration system. Decoration on the surface requires layer-by-layer construction. The construction method is simple but the construction is complicated and cumbersome, and the formed rigid plaster layer is easy to bulge and c...

[0002] Building energy consumption has reached 27.6% of the energy consumption of the whole society. Rigid polyurethane foam is considered to be the most ideal material to achieve 65% energy saving in buildings, and external wall insulation is the best way to realize new buildings, existing buildings and old city renovations. ; At present, there are mainly two types of systems for the external thermal insulation of rigid foam polyurethane panels, namely the thin plastering system and the integrated thermal insulation and decoration system. Decoration on the surface requires layer-by-layer construction. The construction method is simple but the construction is complicated and cumbersome, and the formed rigid plaster layer is easy to bulge and crack; the thermal insulation and decoration integrated system generally uses rigid structural materials as the enclosure decoration layer, which is difficult Continuous production on the production line, and the rigid enclosure finish layer is generally thick, requiring the assistance of shear-resistant mechanical structures such as hangers, pendants, brackets, anchors, etc., requiring refined constructio
