Heat insulating system outside external wall

Abstract

The heat insulating system outside external wall features that there are base layer with alkali resistant strengthening treating agent outer the concrete base wall and connected to the heat insulating board through silicon modified polymer mortar adhesive and plastic anchor part, alkali resistant netted cloth outside the heat insulating board, elastic anticracking silicon modified polymer putty and self-structured waterproof anticracking closing layer between the heat insulating board and the alkali resistant netted cloth, facing silicon modified polymer mortar outside the alkali resistant netted cloth, fire retardant paint around the window and silicon modified acrylate paint in the outmost layer. The present invention has the advantages of simple structure, low cost, easy construction, raised wall surface quality and fire retarding function.

Description

Technical field: [0001] The invention relates to an external thermal insulation system for an exterior wall, in particular to an external thermal insulation system for an external wall that can effectively prevent a series of problems such as hollowing, cracking, and water seepage of the thermal insulation wall and has a fire-blocking function, and can be used in the construction field. Background technique: [0002] In industrially developed countries abroad, external wall insulation has a history of more than 30 years, with a cumulative usage of more than 100 million square meters. In recent years, my country has made beneficial attempts in the aspect of external thermal insulation of external walls, researched and developed several types of external thermal insulation construction methods, such as making foamed polystyrene particle thermal insulation mortar on the external surface of buildings and thin plastering external paste EPS / XPS boards, etc. have achieved certain th...

AI Technical Summary

Problems solved by technology

However, the above-mentioned existing external wall insulation systems are prone to problems such as hollowing, cracking, and water seepage, resulting in failure of insulation. In addition, high-efficiency insulation boards such as EPS and PU boards are all flammable, and can decompose after burning. Gas, due to cost and other reasons, even if a flame retardant is added, it cannot achieve a good flame retardant effect

The above-mentioned disadvantages seriously plague the large-scale promotion and application of energy-saving buildings
