Abstract

The invention discloses a polyurethane flame-retardant nano paint. The polyurethane flame-retardant nano paint comprises following raw materials, by weight, 10 to 20 parts of graphite, 5 to 15 parts of molybdenum disulfide, 5 to 10 parts of aluminium oxide, 2 to 6 parts of xylene, 2 to 6 parts of polyurethane modified epoxy resin, 2 to 6 parts of a curing agent, 12 to 15 parts of a bonding agent, 1 to 4 parts of an auxiliary agent, 15 to 20 parts of purified water, and the like.

Description

technical field [0001] The invention relates to a novel coating and a preparation method thereof, in particular to a polyurethane flame-retardant nano coating. Background technique [0002] The results of investigation on the corrosion of coastal fishery machinery show that due to the harsh working environment of fishing machinery, the corrosion is serious, and the corrosion of the propeller is particularly prominent. Suspension paddles are small propellers driven by diesel engines or other power at the tail of small and medium-sized fishing boats and yachts. They are subject to seawater corrosion, hydraulic mechanical erosion caused by blade rotation, and wear caused by sand particles. paint. [0003] The size of foreign on-hook propellers is small, and the speed is as high as 550 r / min. The propellers are made of aluminum alloy or stainless steel. effect. Domestic propellers are mostly made of cast iron and aluminum, and iron red alkyd primer and nitro topcoat are used ...
