Abstract

The invention discloses a flame-retardant heat-insulating PVC wood-plastic profile. The flame-retardant heat-insulating PVC wood-plastic profile comprises a PVC wood-plastic profile body, wherein a cavity dividing rib is arranged in the PVC wood-plastic profile body, the cavity dividing rib and the PVC wood-plastic profile body are integrally formed, a first cavity and a second cavity are formed in the PVC wood-plastic profile body through the cavity dividing rib, a first flame-retardant heat-insulating coating is arranged in the PVC wood-plastic profile body, a flame-retardant cavity is formed in the inner side of the first flame-retardant heat-insulating coating, the flame-retardant cavity is filled with a flame retardant, and a second flame-retardant heat-insulating coating is arranged on the inner side of the flame-retardant cavity. According to the invention, by arranging the first flame-retardant heat-insulation coating and the second flame-retardant heat-insulation coating, the flame-retardant heat-insulation effect of the PVC wood-plastic profile body can be effectively improved; and the flame-retardant cavity is filled with the flame retardant, and the aluminum hydroxide flame retardant can limit the generation of combustible gas, achieve the effects of heat insulation and oxygen isolation and has good smoke suppression effect.

Description

technical field [0001] The invention relates to the field of wood-plastic profiles, in particular to a flame-retardant and heat-insulating PVC wood-plastic profile. Background technique [0002] Polyvinyl chloride PVC resin itself has good flame retardancy, and its chlorine content is as high as 56%. Due to the flame retardancy, wear resistance, chemical corrosion resistance and comprehensive mechanical properties of PVC plastic, it is the most superior performance-price ratio. Universal material, widely used in the manufacture of pipes, panels and door and window profiles, especially in the building decoration industry with flame retardant requirements; [0003] Although PVC itself is not easy to burn, PVC materials will produce a lot of black smoke during the combustion process, and will release gases such as HCI, CO 2 , CO, toluene and other corrosive poisonous and harmful gases, which pollute the environment and cause "secondary harm" to the human body or equipment.
