Problems solved by technology

[0008] The main problems in the above approach: (1), lower thermal efficiency
(3) The insulation layer is indoors, which will cause trouble for the secondary decoration and the addition of hanging facilities, and will have a great impact on the residents during maintenance
Existing problems: (1), the current layered construction, complex process, large amount of wet work
(2) The thickness uniformity of plastering mortar is not easy to control, generally 3-4mm, if it is too thick, the dry shrinkage stress will be large and easy to crack
(3) It is not easy to maintain on site, and it is easy to shrink and crack
Existing problems: (1) Due to the decoration stacking and external hanging, the facade effect is not rich, and the use is limited
(2) The extruded board and decorative board are fixed by layered expansion nails, and there are many expansion nails passing through the insulation layer, which affects the insulation effect
(3) It is more troublesome to deal with corne

Abstract

The invention relates to a constructional material, in particular to a heat preservation and decoration board for a building exterior wall. The invention has a structure that the board mainly comprises three layers; an inner layer serves as an insulating course, an outer layer serves as a decorative layer and a middle layer serves as a binding course; wherein, the insulating course has a polyphenyl board or a plastic extrusion plate or a polyurethane board; the decorative board has various exterior wall facing dopes or a decorative plate; the binding course is the polymer caking agent layer, the insulating course and the decorative layer are stuck into a whole by the cementing action of the polymer caking agent. The invention has convenient construction, easy manipulation, low cost, good heat prevention effect and strong suitability, thereby contributing to the quick popularization of energy consumption of a building.

Description

technical field [0001] The invention relates to a building material, in particular to a thermal insulation and decoration integrated board for building exterior walls. Background technique [0002] With the progress of the society, people think more about the interdependence between the quality of life and the living environment, and saving energy is the basic national policy of our country. Energy saving, environmental protection, green buildings and materials are the requirements of the living environment, and it is also the embodiment of the value of human scientific research achievements. [0003] In recent years, my country's construction industry has developed rapidly, with an annual increase of nearly 2 billion square meters of construction area. The construction industry has higher and higher requirements for building exterior wall insulation and decoration. At present, my country's building energy consumption accounts for 30% of the total energy consumption, and it...
