Abstract
The invention relates to a coating for an aluminum alloy decoration panel of an elevator. The coating is characterized by comprising the following components in part by weight: 100 parts of polyurethane, 25 to 35 parts of polyisocyanate, 0.1 to 1.0 part of water, 10 to 20 parts of magnesium oxide, 0.1 to 1.0 part of surfactant, 0.01 to 0.1 part of catalyst, 5 to 15 parts of paraformaldehyde, 80 to 100 parts of filler, 1 to 10 parts of melamine, 10 to 20 parts of myeloperoxidase (MPO) and 1 to 10 parts of sodium carboxymethylcellulose (CMC-Na), wherein the catalyst is methyldiethanolamine; and the surfactant is a cationic surfactant. A method for preparing the coating comprises the following steps of: putting the polyurethane and the polyisocyanate into a reaction kettle, stirring, raising the temperature to 50 to 60 DEG C, performing vacuum dehydration, cooling, reducing the temperature to room temperature, adding other auxiliary materials, stirring, grinding for 10 to 30min in a grinding machine, discharging, and packaging. The obtained coating is easy to coat and dry, has a good film-forming property, is smooth, and has high scraping resistance and anticorrosion performance.
Description
Technical field
The present invention relates to a kind of elevator decoration panel coating.
Background technology
The stainless steel surface layer of elevator generally need to adopt aluminium alloy plate to decorate, and aluminum alloy surface need to apply certain scratch resistant and anticorrosive coating.
Summary of the invention
Technical problem to be solved by this invention provides a kind of elevator aluminium alloy decorative panel coating.
For solving the problems of the technologies described above, the present invention is achieved in that
Elevator aluminium alloy decorative panel coating comprises the following component in weight part:
Urethane 100;
Polyisocyanates 25-35;
Water 0.1-1.0;
Magnesium oxide 10-20;
Tensio-active agent 0.1-1.0;
Catalyzer 0.01-0.1;
Poly methyl alcohol 5-15;
Filler 80-100;
Trimeric cyanamide 1-10;
MPO 10-20；
CMC-Na 1-10。
Described filler is any of calcium carbonate, talcum powder, silicon-dioxide, filler can increase the thickness of coating, regulate rheological property, improve physical strength, put forward the weather resistance of coating and reduce cost, wherein calcium carbonate, talcum powder can improve the soft and moist type of coated membrane, reduce water-permeable, the internal stress when eliminating paint solidification; Silicon-dioxide can improve the mechanical property of coated membrane, plays the effects such as thickening, thixotroping, sag prevention.
Described catalyzer is methyldiethanolamine.
Described tensio-active agent is cats product.
The preparation method is as follows: urethane, polyisocyanates place in the reactor, stir and are warming up to 50-60 ℃, and vacuum hydro-extraction cools to room temperature, adds other auxiliary material, grind 10-30min in stirring, the shredder, discharging, packing.
The elevator aluminium alloy decorative panel coating of the present invention's preparation is colourless viscous fluid, is easy to coating, good film-forming property, smooth, is easy to oven dry, and Anti-scratching and antiseptic property are good.
