Problems solved by technology

[0004] However, in the prior art, PET composite thermal insulation and decorative panels are constructed by dry-hanging, and the wall surface needs to be plastered and waterproofed before construction. Due to the gaps in the dry-hanging construction process of the panels, the surface of the aluminum plate and the metal The fixing part is also a heat-conducting structure, so there is still a thermal bridge between the PET composite thermal insulation decorative board and the wall, and the construction process is more cumbersome and the construction period is longer

Abstract

The invention relates to the technical field of building heat preservation and decoration, and particularly relates to a PET composite heat preservation and decoration integrated structure and a construction method thereof. The construction method comprises the steps that the surface of a PET structure foam board is heated to 230-380 DEG C for 10-30 seconds, so that the surface of the PET structure foam board is melted; an aluminum board is preheated to 50-100 DEG C and attached to the PET structure foam board with the melted surface, the pressure of 0.2-0.8MPa is applied to the attached board, the board is cooled and cut into the required size after 10-30 seconds, and a PET-aluminum board composite heat preservation and decoration board is prepared; and heat preservation concrete capable of being subjected to spraying construction is prepared to conduct wall pasting on the PET-aluminum board composite heat preservation and decoration board, and the effects that a heat bridge is blocked, the heat preservation and waterproof effects are improved, and the construction efficiency is improved are achieved.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation and decoration, in particular to a PET composite thermal insulation and decoration integrated structure used in conjunction with a cement-based thermal insulation bonding inner layer and a construction method thereof. Background technique [0002] As people's demand for building living environment and living comfort continues to strengthen, coupled with the increasing urgency of reducing energy consumption and environmental pollution, external wall insulation technology, as an important part of building energy conservation, has received more and more attention. External wall insulation is a layer of thermal insulation material fixed by bonding materials on the outside of the building envelope. The development of external wall insulation technology in China is becoming more and more mature, mainly including rock wool external wall insulation system and EPS / XPS board external wall...
