Insulation Decorative Board Exterior Wall Exterior Insulation System

Abstract

The invention discloses an external heat preservation system for the exterior wall of a heat preservation decorative board, which is applied in the field of building walls and solves the technical problem that the heat preservation and decoration functions cannot be taken into account in the prior art. The wall and the base wall are fixed by bonding and anchoring the thermal insulation decorative board. The thermal insulation decorative board is made of a gel glass bead thermal insulation board composite decorative surface layer, or a composite light-cured decorative panel, or a composite thin stone panel. The thermal insulation decorative board with excellent thermal insulation performance and good decoration has been prepared. It is a functional system material integrating thermal insulation and decoration. It is placed on the outside of the building and is a non-load-bearing thermal insulation structure fixed on the base wall.

Description

technical field [0001] The invention relates to building wall materials, in particular to an external thermal insulation system for an external wall of a thermal insulation decorative board. Background technique [0002] In recent years, energy saving and environmental protection have become a common topic all over the world. With the implementation of my country's new building energy-saving standards, the building has developed from a low-level solution for people's living to a high-level green ecological building. In the heat consumption of buildings, the heat consumption of exterior walls accounts for about 30%. Therefore, how to reduce the K value of exterior walls is one of the main ways to reduce energy consumption of buildings. Therefore, exterior wall insulation technology has emerged as the times require. [0003] Among the many thermal insulation technologies, the one that can significantly reduce the K value is the external thermal insulation technology of extern...

Problems solved by technology

[0004] At present, there are many external thermal insulation systems and construction methods for external walls. Most of the thermal insulation materials on the market are polystyrene materials, and the external thermal insulation construction is carried out by pasting small pieces. The main defect of this method is that the thermal resistance is small. , it is difficult to achieve 65% energy saving index; and the small pasted board seams are easy to seep into the rainwater. Once the rainwater seeps into the board seams, it will damage the wall insulation layer after the freeze-thaw cycle

In recent years, polyurethane has also been used as the insulation layer. The method is to remove the formwork without removing the formwork. In addition to installing the formwork, a fine exterior decorative surface layer must be made, which is labor-intensive, prolongs the construction period, and increases the construction cost.
