Description

A composite waterproof and thermal insulation integrated system

technical field

The utility model relates to a waterproof system, in particular to a composite waterproof and thermal insulation integrated system.

Background technique

For buildings, its most important function is not only the stability and durability of its structure, but also waterproof and moisture-proof. Since the waterproofing project accounts for a very small proportion in the total cost of the construction and installation project, usually about 1% to 2%, it has not been valued by the relevant parties all the time.

In traditional roofing engineering, the waterproof layer and the insulation layer are set separately. The waterproof layer is generally made of waterproof membrane or waterproof coating, and the insulation layer is mostly made of XPS extruded foam board, rigid polyurethane foam, etc. Due to the separate construction of the waterproof layer and the thermal insulation layer, on the one hand, the consumption of labor and bonding materials is increased, and an additional protective layer and leveling layer are added, resulting in a long construction period and high cost; in addition, there is no bonding between the waterproof layer and the thermal insulation layer. The water absorption rate of the insulation layer is high or low, which is a channel for water channeling, resulting in a great leakage hidden danger.

In recent years, hard foam polyurethane that has reached the specified density and closed cell ratio has also been used as a structural layer that integrates waterproofing and heat preservation. To ensure quality and other factors, its waterproof performance is very questionable.

The integrated decoration and thermal insulation system for building exterior walls uses decorative panels and rigid polyurethane foam, XPS foam boards and other thermal insulation materials in the factory. Time-consuming and labor-intensive problems, but there is no good solution for the waterproofing of board seams, and the waterproof level is low, so it cannot be used for waterproofing and heat preservation of roofs.
