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 construction, resulting in an increase in labor costs

[0003] The prior art discloses a hard foam polyurethane composite board with an application number of 200510045523.9 and its production process. It uses hard foam polyurethane as the heat preservation base material, and polymer sheets are provided on both sides. The board is based on a thin plastering system. The insulation material of the construction method does not have a finish layer, and requires cumbersome layer-by-layer construction, resulting in an increase in construction and personnel costs

The prior art also discloses a real stone varnish composite sheet with the application number of 200810171913.4 and its production method. It is to flat-coat or spray real stone varnish on the release material and then dry it for demoulding. It is an industrial The real stone paint finish layer produced by chemical production not only needs demoulding materials in the production process, but also has no enclosure structure layer, which has low impact strength and is easy to deform. It cannot be used as an enclosure finish layer integrated with heat preservation and decoration. Foam line for sheet compounding
