Rigid-foam polyurethane heat-preserving and decorating integration plate and manufacturing method thereof

Abstract

The invention provides a rigid-foam polyurethane heat-preserving and decorating integration plate and a manufacturing method of the integration plate. The rigid-foam polyurethane heat-preserving and decorating integration plate is composed of a decorating plate, a BOPP film, a polyurethane plate and cement glass fiber felt. The lower surface of the decorating plate is covered with the BOPP film. The upper surface of the decorating plate is bonded with the polyurethane plate, and pouring is adopted as the bonding mode. The cement glass fiber felt is bonded on the upper surface of the polyurethane plate. According to the manufacturing method, the decorating plate is conveyed to a polyurethane plate serial production line through a roller shaft conveyor, and the working procedures of polyurethane pouring, foaming, solidifying and cutting are finished in a one-off mode. The rigid-foam polyurethane heat-preserving and decorating integration plate has the functions of safety fire prevention, energy conservation and heat preservation, falling and scaling of internal heat-preserving materials can be prevented, production of the continuous production line is achieved, and the production efficiency is improved.

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
