Abstract

The invention discloses a heat-resistant and wear-resistant composite board and a preparation method thereof, and specifically relates to the technical field of composite boards, including: a substrate, a wear-resistant alloy board, a heat-resistant glue layer and a wear-resistant coating powder. In the present invention, the heat resistance of the heat-resistant and wear-resistant composite board can be effectively improved, so that the internal heat distribution of the composite board is more uniform, the internal damage of the composite board is reduced, the service life is prolonged, and the wear resistance of the composite board is improved at the same time; modified nano tin oxide Antimony and modified nano-boron nitride can improve the heat resistance of the heat-resistant adhesive layer; modified silicon carbide whiskers and modified nano-titanium diboride can enhance the heat resistance and wear resistance of the wear-resistant coating, thereby improving the composite The heat-resistant and wear-resistant performance of the board, the connection between the substrate and the wear-resistant alloy plate is realized by two methods of glue connection and brazing, which can effectively strengthen the stability of the connection of the composite board, and the multi-layer circular distribution avoids direct transfer of local heat to the substrate , more evenly heated.

Description

technical field [0001] The invention relates to the technical field of composite boards, more specifically, the invention relates to a heat-resistant and wear-resistant composite board and a preparation method thereof. Background technique [0002] Composite panels are generally divided into: metal composite panels, wood composite panels, color steel composite panels, rock wool composite panels and so on. Composite panels are panels composed of layers of different materials with different functions. For example, the three-in-one board of concrete, foam insulation layer and surface waterproof layer for roofing, sandwich board is also a kind of composite board. Wear-resistant composite plate, that is, double-metal clad wear-resistant steel plate, is a plate product specially used for large-area wear conditions. It is formed by surfacing welding on ordinary steel plates, heat-resistant steel plates, and stainless steel plates with a volume fraction of more than 50%. Cr 7 C ...
