Problems solved by technology

Although wood-plastic panels and wood plywood have the advantages of being green and environmentally friendly, they are not strong enough when used as wall panels. Although steel plates are high in strength, they are in short supply of steel resources, which is not conducive to sustainable development.
Traditional brickwork or reinforced concrete wall panels have high strength, but poor sound insulation, waterproof, flame retardant and thermal insulation effects

Embodiment 1

[0015] According to the actual situation, 10kg of cement mortar, 10Kg of expanded polypropylene, and 2kg of magnesium powder were weighed, blended, and pressed into a 20mm thick composite board. After it solidifies, apply glue on the upper and lower surfaces. Take two 2mm thick magnesium plates and paste them on both sides of the composite plate respectively. Finally, it is pressed by double rollers to increase the bonding firmness of the board, and a lock for fixing is added. The obtained boards are cut into square templates to facilitate construction and transportation.

Embodiment 2

[0017] According to the actual situation, 10kg of cement mortar, 15Kg of foamed polyurethane, and 3kg of magnesium powder were weighed, blended, and pressed into a 30mm thick composite board. After it solidifies, apply glue on the upper and lower surfaces. Take two 10mm thick magnesium plates and paste them on both sides of the composite plate respectively. Finally, it is pressed by double rollers to increase the bonding firmness of the board, and a lock for fixing is added. The obtained boards are cut into square templates to facilitate construction and transportation.

Embodiment 3

[0019] According to the actual situation, 15kg of cement mortar, 20Kg of foamed polypropylene, and 5kg of aluminum hydroxide powder were weighed, blended, inserted into steel bars, and pressed into a 10mm thick composite plate. After it solidifies, apply glue on the upper and lower surfaces. Take two 3mm thick magnesium plates and paste them on both sides of the composite plate respectively. Finally, it is pressed by double rollers to increase the bonding firmness of the board, and a lock for fixing is added. The obtained boards are cut into square templates to facilitate construction and transportation.

Abstract

The invention discloses a novel composite sandwich wallboard and a preparation method thereof. The preparation method of the novel composite sandwich wallboard comprises the three-layer sandwich process, specifically, cement mortar, inorganic flame retardants and foaming macromolecule plastic are together mixed and pressed to be a plate at first; after the plate is solidified, the two surfaces of the plate are coated with glue to serve as sandwich layers; and then two magnesium plates with the same size are taken and are pasted on the upper surfaces and the lower surfaces of the sandwich layers. According to the novel composite sandwich wallboard, the heat preservation performance, the sound insulation performance, the waterproof performance and the flame retardant performance are improved on the premise of ensuring the mechanical strength, the cost can be reduced, and the environmental protection requirement of sustainable development is met. The preparation method of the novel composite sandwich wallboard is easy and capable of achieving industrialization easily and can be widely used in indoor wallboards under various circumstances.

Description

technical field [0001] The invention relates to the field of wallboards, in particular to a novel composite sandwich wallboard and a preparation method thereof. Background technique [0002] Traditional building wall panels are mostly made of reinforced concrete or bricks. With the rapid development of my country's construction industry, various wall panels have emerged, including wood-plastic panels, wood plywood panels, color steel tiles, and steel panels. Although wood-plastic panels and wood plywood have the advantages of being green and environmentally friendly, they are not strong enough when used as wall panels, and although steel plates are high in strength, they are in short supply of steel resources, which is not conducive to sustainable development. Traditional brickwork or reinforced concrete wall panels have high strength, but poor sound insulation, waterproof, flame retardant and thermal insulation effects. Contents of the invention [0003] In view of this...
