Embodiment 2

[0017] Weigh 10Kg of polyvinyl chloride, 2Kg of wood flour, 0.8Kg of DPT foaming agent, and 3kg of aluminum hydroxide and blend them in a high-speed mixer. The mixed sample was extruded into a flame retardant foamed sheet through a sheet extruder, and a 2mm surface layer of PMMA was co-extruded. The resulting panels are cut into rectangles to facilitate construction and transportation

Embodiment 3

[0019] Weigh 20Kg of polyvinyl chloride, 3Kg of straw powder, 0.4Kg of AC foaming agent, and 1kg of magnesium powder and mix them in a high-speed mixer. Extrude the mixed sample into a flame-retardant foamed sheet through a sheet extruder, and co-extrude a 0.5mm surface layer of ASA. The resulting panels are cut into waves to facilitate construction and transportation

Embodiment 4

[0021] Weigh 5Kg of polyvinyl chloride, 3Kg of calcium carbonate, 0.4Kg of AES foaming agent, and 3kg of compound flame retardant and mix them in a high-speed mixer. Extrude the mixed sample into a flame-retardant foamed sheet through a sheet extruder, and co-extrude a 2.5mm surface layer of ASA. The resulting panels are cut into diamond shapes to facilitate construction and transportation

[0022] It can be seen that the flame-retardant exterior wall decorative panel provided by the invention and its preparation method have the following advantages:

[0023] (1) The flame-retardant exterior wall decorative panels can be cut into various shapes as needed, and patterns can be added on the surface by thermoplastic methods to enhance the aesthetics

[0024] (2) The flame-retardant exterior wall decorative panel provided by the present invention can not only achieve better aesthetic effect, but also have the characteristics of noise reduction, UV resistance, flame retardancy and ...

Abstract

The invention discloses a novel flame-retardant exterior wall decoration plate and a preparation method thereof. The preparation method comprises: preparing a flame-retardant foaming plate while co-extruding an anti-ultraviolet resin surface layer on the upper surface of the plate, wherein the components of the formula comprise polyvinyl chloride (PVC), a foaming agent, a bio-based material or aninorganic filler, an inorganic flame retardant agent, and an anti-ultraviolet resin. According to the present invention, the flame retardancy, the light weight, the sound insulation, the aging resistance, the thermal insulation and other performances can be improved under the premise of the assurance of energy saving and thermal insulation, the cost can be reduced, and the environmental protectionrequirements of sustainable development can be met; and the preparation method is simple and is suitable for industrial production, and the obtained product can be widely used for building exterior wall decoration plates.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a novel flame-retardant exterior wall decorative board and a preparation method thereof. Background technique [0002] At present, decorative panels for building exterior walls are generally made of facing stone materials such as marble and granite, which have good aesthetics. However, these materials have a large proportion and poor thermal insulation and sound insulation performance. In order to save energy more effectively, foamed panels are more and more widely used in exterior wall decoration panels. At the same time, the flame retardant requirements for similar foamed sheets are getting higher and higher [0003] The invention relates to the preparation of a novel flame-retardant exterior wall decorative board. The method adopts an extrusion process to co-extrude polyvinyl chloride, a foaming agent, an inorganic flame retardant, and wood powder and other bio-based ma...
