Flame-retardant high-weather-resistance hanging board

Abstract

The invention provides a flame-retardant high-weather-resistance hanging board and relates to the technical field of hanging boards. The flame-retardant high-weather-resistance hanging board comprisesa flame-retardant layer, a thermal insulating layer and a substrate arranged in sequence. One end of the substrate is provided with a locking device, and the other end of the substrate is provided with a clamping device which cooperates with the locking device. The locking device comprises a groove, at least one telescopic locking component which is arranged at a side wall of the groove, an elastic part which is fixedly connected to the groove and is used for blocking the locking component to keep the locking component to be compressed. The clamping device comprises a raised piece which is provided with a plurality of through holes, and the locking component can pass through a through hole. The connection of the hanging board is completed through the cooperation of the locking device andthe clamping device, an installed hanging board structure is firm and is not loosened after long-term use, the hanging board is easy to install and can withstand high temperature, and the hanging board has high thermal stability and can resist degradation, aging and fading caused by ultraviolet radiation.

Description

technical field [0001] The invention relates to the technical field of hanging boards, in particular to a flame-retardant high weather-resistant hanging board. Background technique [0002] From the architectural point of view, the external wall hanging board is a construction method, which is to hang the board on the outside of the wall through dry hanging and other construction methods to achieve decoration or heat preservation. From the product point of view, the external wall hanging board is a kind of building material, which is a building board used for the external wall. External wall hanging panels must have basic properties such as corrosion resistance, high temperature resistance, aging resistance, no radiation, fire prevention, insect resistance, and no deformation. At the same time, they must also have beautiful appearance, simple construction, environmental protection and energy saving. Common exterior wall hanging boards include fiber cement boards, aluminum-p...

AI Technical Summary

Problems solved by technology

[0004] 1. Spraying: its environmental pollution is large, and the paint layer is prone to cracks, especially for some profiles and plates, its adhesion is low, and some paints have insufficient aging resistance

[0005] 2. Coating: such as figure 1 As shown, the currently used film is basically composed of three layers, and its price is relatively high when it meets the performance requirements, and the low price cannot meet the outdoor photothermal aging performance and the requirements of the national standard GB / T8814

In addition, due to strict process control requirements during film production, this kind of film is prone to delamination during use.

[0006] 3. Co-extrusion: such as figure 2 As shown, for polymer materials, the co-extrusion processing method of two materials is used to complete the lamination of the functional layer and the base layer. Uniformity and other defects affect the appearance quality, and there are problems such as deformation caused by internal stress; moreover, it is suitable for large batch processing, while small batch processing has the problem of greatly increased scrap rate and cost

[0007] 4. Printing: Including direct printing or thermal transfer printing, it is difficult to meet the performance requirements due to problems such as thermal and optical aging; therefore, it can only be used indoors; and if thermal and optical aging is required, the cost will be very high. thereby affecting its promotion and application

[0008] The hanging boards in the prior art have some problems, such as poor high temperature resistance, complicated installation process, easy water ingress at the joints, causing corrosion or corrosion of the internal structure, shortening the service life of the hanging boards, and at the same time, its resistance to strong sunlight Poor ability to irradiate ultraviolet light, degradation, aging, fading will occur

The structure of the splicing method of the hanging boards in the prior art is unstable and prone to loosening, and the use of too many nails for fixing affects the appearance of the hanging boards
