Description

A metal insulation tile

technical field

The utility model relates to a heat-insulating tile, in particular to a metal heat-insulating tile with excellent nanoscale waterproof and heat-insulating performance.

Background technique

Few of the existing roofing materials can meet the fire protection requirements. For example, color steel tiles. If a fire occurs indoors, especially in some factories, foam and interlayers are added to the interior for heat insulation. When burned and heated, toxic gases will be produced. For example, stupid (a dangerous chemical substance) can cause great harm to the human body. There is also a kind of heat insulation tile, which is made of cement or asbestos, and some are made of simple metal zinc sheet. This kind of heat insulation tile has the following disadvantages: 1. The heat insulation tile made of cement or asbestos is generally effective and waterproof Poor performance; 2. The heat insulation tile made of zinc sheet is too thin, the heat insulation effect is poor, and the corrosion resistance is also poor.

Steel structure buildings usually use foam sandwich panels, rock wool sandwich panels, glass wool sandwich panels, polyurethane foam sandwich panels, phenolic foam sandwich panels, paper honeycomb sandwich panels, etc. as building wall and roof materials. Heat insulation and sound insulation. The various sandwich panels mentioned above are made by pasting or extruding different insulation materials in the middle of two layers of color steel plates. The thickness is generally 50-300mm, with many consumables, increased weight and volume, cumbersome procedures, and high transportation and manufacturing costs. Under sunlight, the surface of various sandwich panels still absorbs infrared rays and accumulates heat, so the service life of the color steel plate on the surface of the sandwich panel is shortened.

Another kind of synthetic resin tile (also known as color steel glazed tile) on the market is made of ultra-high weather-resistant engineering resin, which can maintain its original color even if it is exposed to ultraviolet rays, moisture, heat, and cold for a long time. The stability of the color, so it is widely used in roofing fields such as flat-to-slope conversion, villas, mobile houses, garden pavilions, industrial workshops, and standard workshops. However, the interior of the synthetic resin tile has the characteristics of high porosity, so it is easy to absorb water during storage. After absorbing water, it will greatly affect the heat insulation and dielectric properties of the synthetic resin tile, and it will also increase the synthetic resin tile. Unfavorable factors such as weight. Therefore, preparing a stable and non-moisture-absorbing heat-insulating tile that is exposed outdoors and outdoors for a long time is a technical key to solving the field of heat-insulating materials.
