A rigid foam polyurethane thermal insulation and decoration integrated board and its preparation method

Abstract

A hard foam polyurethane thermal insulation and decoration integrated board and a preparation method thereof. The rigid foam polyurethane insulation and decoration integrated board is composed of a decorative board, BOPP film, polyurethane board, and cement glass fiber felt. The lower surface of the decorative board is covered with BOPP film; the upper surface of the decorative board is bonded to the polyurethane board by pouring; the upper surface of the polyurethane board is bonded with cement glass fiber felt. In the preparation method, the decorative board is transported to the polyurethane board continuous production line through a roller conveyor, and the polyurethane casting, foaming, curing and cutting processes are completed at one time. The rigid polyurethane thermal insulation and decoration integrated board of the present invention has the functions of safety, fire prevention, energy saving and heat preservation, can prevent internal insulation materials from falling off and peeling off, realize continuous production line production, and improve production efficiency.

Description

technical field [0001] The invention relates to the technical field of production of thermal insulation boards for external thermal insulation of exterior walls, in particular to a rigid foam polyurethane thermal insulation and decoration integrated board for external thermal insulation of external walls and a preparation method thereof. Background technique [0002] The traditional rigid foam polyurethane thermal insulation and decoration integrated board is generally a product that combines the thermal insulation layer and the decorative surface layer at one time under factory conditions, taking into account the dual functions of thermal insulation and decoration, but it is usually the first to produce the finished product Polyurethane insulation board is combined with polyurethane glue and decorative surface layer, which greatly increases the operating procedures and labor intensity. [0003] In the Chinese Patent Application Publication CN103104079A, a modified phenolic ...

AI Technical Summary

Problems solved by technology

The production process of the polymer cement membrane layer and the polymer cement sheath layer is complicated, and in the pouring connection process, a layer of polymer cement membrane is first laid, then polyester ammonia is poured, and another layer is laid on the polyester ammonia Polymer cement coils, that is, the process itself needs to be completed in several steps and cannot be formed at one time
