preparation example Construction

[0045] The invention also discloses a method for preparing a composite board, comprising the following steps:

[0046] (A) After the fireproof hard material is ball-milled into powder, it is mixed with the binding substance to obtain a mixture;

[0047] The fireproof hard material is a discarded non-metallic material;

[0048] The adhesive substance includes: waste engine oil, polyvinyl alcohol, magnesium oxide and unsaturated resin adhesive; the mass ratio of waste engine oil, polyvinyl alcohol, magnesium oxide and unsaturated resin adhesive is (10-20): (10-20 ):(35~45):(25~35);

[0049] The mass ratio of fireproof hard material and adhesive substance is (70wt%~80wt%): (20wt%~30wt%);

[0050] (B) stirring and dissolving the mixture described in step (A), extruding and drying to obtain the substrate;

[0051] (C) Fireproofing the surface of the metal panel and the metal base plate, and pressing them with the polymer film after heating to obtain a composite metal base plate ...

Embodiment 1

[0063] Get 70 kilograms of fireproof hard materials that are made up of discarded glass, discarded ceramics, fruit shells and waste plastics and carry out ball milling. The particle size after ball milling is 300 meshes. It is mixed with an adhesive substance composed of an unsaturated resin adhesive to obtain a mixture. The ratio of discarded glass, discarded ceramics, fruit shells and waste plastics in the fireproof hard material is not limited, and the mass ratio of waste engine oil, polyvinyl alcohol, magnesium oxide and unsaturated resin adhesive is 15:15:40:30 .

[0064] The mixture was stirred and dissolved in an environment of 50° C., extruded by an extruder, and dried naturally in an oven at 120° C. to obtain a substrate.

[0065] The stainless steel is prepared into two 1mm stainless steel plates, which are heated to 120°C on a heat paste machine, and the EVA film is laminated. Pressing two stainless steel plates with the same EVA film bonded to the substrate, the ...

Abstract

The invention provides a composite plate, which comprises a base plate, a metal surface plate and a metal bottom plate, wherein the metal surface plate is arranged at one side of the base plate, the metal bottom plate is arranged at the other side of the base plate, high-polymer films are respectively arranged between the base plate and the metal surface plate as well as between the base plate and the metal bottom plate, and the base plate is made of 70wt% to 80wt% of fireproof hard material and 20wt% to 30wt% of adhesive material. A preparation method comprises the following steps of carrying out ball milling on the waterproof hard material into powder, and mixing with the adhesive material to obtain a mixture; stirring and dissolving the mixture, extruding and forming, and drying to obtain the base plate; carrying out waterproof treatment on the metal surface plate and the metal bottom plate, heating, and respectively laminating with the high-polymer films; and respectively laminating the two sides of the base plate with the metal surface plate and the metal bottom plate. The composite plate has the advantages that by adopting the base plate with fireproof and high temperature-proof performances and low cost, after the base plate is laminated with the metal bottom plate and the metal surface plate, the fireproof, environment-friendly, anti-aging and high temperature-proof effects are better.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a composite board and a preparation method thereof. Background technique [0002] Composite board is a commonly used building material, which can be used for walls and floors, especially for high-rise buildings, hotels, bars, cafes, dance halls (KTV), supermarkets, shopping malls, and houses for enterprises and institutions. , residential and other interior and exterior wall decoration. [0003] The composite panels commonly used on the market include metal composite panels, wood composite panels, rock wool composite panels and color steel composite panels. Among them, wood composite panels are cheap, but have poor fire performance; metal composite panels, rock wool composite panels, and color steel composite panels have good fire performance, but their cost is high. Contents of the invention [0004] The technical problem solved by the invention is to provide a composite bo...
