Abrasion-resistant multi-layer polyurethane lacquer coating - from polyester mixt., esp. for fibre-reinforced synthetic blades in turbo-machines |
摘要 |
<p>A protective coating for articles subjected to abrasion consists of the reaction prod. prepd. in absence of an accelerator, from (a) polyethylene glycol adipate and a polyester from glycerin, adipic acid with phthalic acid, and (b) an isocyanate resin from 3 moles toluylene diisocyanate and 1 mole trimethylolpropane. The coating is applied in several pref. 3 layers with total thickness 0.1-1 mm (0.1-0.5 mm) with the elasticity increasing towards the outer layer. The ratio OH: NCO is 1: 0.6-1.8. The coating is esp. used on blades for turbo-machines, formed of several layers of fibre-reinforced synthetic matrices. Abrasion-resistance is considerably better than with known polyurethane la cquers.</p> |
