Description

Water-repellent rock wool board for ultra-wide exterior wall insulation

technical field

The utility model relates to the technical field of building thermal insulation, in particular to a water-repellent rock wool board for thermal insulation of an ultra-wide outer wall.

Background technique

Rock wool board, also known as rock wool warm board, is a new type of fireproof, thermal insulation and heat insulation material, which is made of basalt as the main raw material and processed by high temperature melting. At present, the thermal conductivity of the rock wool board used in thermal insulation projects in the construction market is 0.045, and the specifications with high density and large thickness can be used to meet the requirements of 75% of thermal insulation and energy saving. Implementing energy-saving and emission-reduction policies for buildings is a strategic task in my country. As a key indicator of green buildings, energy-saving and emission-reduction, building exterior wall thermal insulation performance is highly valued by the whole society. The traditional exterior wall insulation materials are mainly based on organic materials such as EPS, XPS and PU. Although organic materials have excellent thermal insulation performance, their fire resistance is the Achilles heel. It is completely flame retardant under open fire, and will release a large amount of toxic gas when burning. Once a fire occurs, it will definitely cause huge losses to people's lives and properties. As human beings have higher and higher requirements for environmental protection, in order to prolong the service life and aesthetics of buildings, the exterior surfaces of buildings are usually subjected to thermal insulation treatment and related decorative treatments. However, due to the occurrence of many building thermal insulation fire incidents in recent years, it has triggered the thinking of thermal insulation and fire protection from all walks of life. The unprecedented fire performance of thermal insulation materials has attracted great attention from all walks of life in the industry. However, many thermal insulation material fires are generated during the construction process, such as: electric welding, open flames, and bad construction habits. During the combustion of these materials, the molten droplets and toxic fumes that are continuously produced, as well as the chlorofluorocarbons, hydrofluorocarbons, freons and other gases released at the same time, can not be ignored. In the process of thermal insulation design, the system with better fire performance and excellent thermal insulation performance will be more recognized by the market.

Utility model content

The purpose of the utility model is to provide a super-wide hydrophobic rock wool board for external wall thermal insulation with simple structure, good waterproof effect, firm bonding, good thermal insulation performance, good sealing performance, firm and stable use, and good limiting effect.

The utility model provides the following solutions for solving the technical problem:

An ultra-wide water-repellent rock wool board for thermal insulation of external walls, comprising a base wall, characterized in that a plurality of pre-embedded limit hooks are arranged on the outer wall of the base wall, and the outer wall of the base wall is provided with a plurality of pre-buried limit hooks. A rock wool board layer is glued on it, one side of the rock wool board layer is clamped with the limit hook, the outer side of the rock wool board layer is sequentially provided with a thermal insulation layer and a waterproof layer, and the outer wall of the thermal insulation layer is provided with a thermal insulation layer and a waterproof layer. There are a plurality of zigzag grooves, a plurality of zigzag protrusions are arranged on the inner wall of the waterproof layer, and the protrusions and the grooves are inserted into each other and bonded together by an adhesive.

The edge-holding strip is provided at the connection gap of the rock wool board layer, and the edge-holding strip has a connecting column, and the connecting column is fixedly connected with the connection hole preset on the side wall of the base layer. The top of the strip is provided with a sealing edge.

A plurality of drainage grooves are arranged on the outer wall of the waterproof layer.

The thermal insulation layer is a composite structure, which is formed by bonding double-layer alkali-resistant glass fiber mesh cloth with an adhesive.

The waterproof layer is a flexible water-resistant putty, the outer side of the flexible water-resistant putty is provided with a paint finish, and the binder is a polymer plastering mortar.

In the utility model, a plurality of limit hooks are arranged on the base layer of the wall body, so that the connection between the rock wool board and the base layer of the wall body is more firm, the rock wool board is hung on the thermal insulation layer and the waterproof layer, and the thermal insulation layer and the waterproof layer are hung. The waterproof layers are bonded together by adhesive, so that the zigzag protrusions and grooves are snapped together, which makes the connection more firm and prevents loosening. The waterproof sealing effect of the board is better, reducing the water seepage of the rock wool board.
