Abstract

The invention discloses a high-wearability hollow rail aluminum alloy plate which comprises an aluminum alloy plate matrix and a high-wearability polyurethane primer coating the surface of the aluminum alloy plate matrix. The high-wearability polyurethane primer comprises the following raw materials in part by weight: 30-40 parts of acrylic polyurethane, 15-25 parts of modified cyanate resin, 1.3-1.5 parts of talcum powder, 0.5-1 part of superfine barium sulfate, 0.6-0.9 part of a de-foaming agent, 0.5-0.8 part of a leveling agent and 0.3-0.6 part of a film forming agent. The high-wearabilityhollow rail aluminum alloy plate disclosed by the invention has excellent wearability and simultaneously has good film-forming property and processing property.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy plates, in particular to a high wear resistance hollow track aluminum alloy plate. Background technique [0002] Aluminum alloy plate is an industrial building material, which is used in various industries according to different materials. According to the surface treatment method, it can be divided into two categories: non-painted products and painted products. The industries used include aircraft structures, rivets, missile components, truck wheels, packaging and thermal insulation aluminum foil, heat exchangers, bulkheads, wing ribs, spars, etc. [0003] However, the wear resistance of the existing aluminum alloy plates for hollow rails is not high, and cannot meet people's daily needs. Contents of the invention [0004] Based on the technical problems in the background technology, the present invention proposes a high wear resistance hollow track aluminum alloy plate; the invention h...
