Abstract
The invention relates to a hydroxyl resin composition and a solvent-free polyurethane putty containing the same. The resin composition is prepared by mixing resins that have two molecular structures.The prepared solvent-free polyurethane putty consists of a component A and a component B, wherein the compositing ratio of the component A and the component B is 5-6:1; the component B is a curing agent; and the component A consists of an assistant and 30-40 parts by weight of the hydroxyl resin composition. The solvent-free polyurethane putty has properties of excellent adhesion and self polymerization; the drawing intensity of the dried putty reaches 4.0Mpa above which meets the requirement of a fan blade. The impact resistance of the solvent-free polyurethane putty reaches 50kg, and the flexibility reaches 10mm. The putty is resistant to temperature change in a range from -40 DEG C to 40 DEG C.
Description
Technical field
The solvent-free polyurethane putty that the present invention relates to a kind of hydroxy resin composition and contain this hydroxy resin composition.
Background technology
Along with the deterioration of world energy sources situation, wind-power electricity generation is developed rapidly as green energy resource.Wind-powered electricity generation is mainly caught wind energy and then is driven generator for electricity generation by fan blade.This facility need be installed in air port, plateau, mountain area part, and temperature variation is very big throughout the year, and has dust storm to impact, expose to the sun and rain, and is very high to the substrate surface performance requriements.Because fan blade adopts fiber glass epoxy to do base material more, and the weathering resistance of fiber glass epoxy is bad, need be coated with high performance paint outside the surface, again because the inevitable defective in manufacturing processed surface needs high performance putty to fill up defective again.This putty requires to have stronger bonding force, force of cohesion, and this just requires cross-linking density to want big and has quite high shock-resistance and snappiness, and physicals can not be burst apart in shrinkage strain under cold condition.
At present in the industry comparative maturity be atomic lime putty, solvent borne polyurethane putty and epoxy ester putty etc., fast drying, grinability are good, the advantage of strong adhesion though have, but snappiness variation and shrinkability are big at low temperatures, and bonding force, force of cohesion deficiency are not suitable for fan blade and use.
Summary of the invention
Technical problem to be solved by this invention is the defective that overcomes prior art, the solvent-free polyurethane putty that a kind of hydroxy resin composition is provided and contains this hydroxy resin composition.
