Abstract
The invention relates to a polyurethane finish paint. The invention is characterized in that the polyurethane finish paint is prepared by mixing aids, resins, a filler, matting powder, a solvent and a curing agent. The acrylic resin and polyurethane resin used as film formers are compounded with the polyurethane resin and hydroxyacrylate resin to obtain the coating with excellent drying property and mechanical properties. The paint has favorable ply adhesion, and thus, is beneficial to coating repair. The paint has high solid content, can effectively lower VOCs (volatile organic compounds), and satisfies the serious requirements for the environment. By selecting hexamethylene diisocyanate biuret as the curing agent, the finish paint has better impact resistance and water resistance. The dispersing agent, leveling agent, defoaming agent and other aids are proportionally added in the formula to perform favorable surface effects, but can obviously lower the surface tension of the coating, influence the recoating of the paint film and lower the overcoatability.
Description
Technical field
The present invention relates to coatings decoration field, particularly a kind of polyurethane finish.
Background technology
Polyurethane finish, owing to having good ornamental, chemical-resistant, good weather-proof and non-corrosibility, has been successfully applied to the fields such as furniture, vehicle, steamer, aircraft now, has become the focus of coatings decoration area research.Polyurethane finish construction is general adopts artificial air's spraying; due to the complicacy of construction condition; such as: dust in air too much " improper ventilation " workers carry is not protected, paint surface is inevitably caused to fall upper dust or damage etc. of colliding with, so just needs repairing again.General repairing, in order to not affect surface aesthetic, surface need through whole grinding process, increase surfaceness, improve ply adhesion, but for complex structural member, sometimes whole grinding process is difficult to, such polyurethane finish always there will be and does not have burnishing part to adhere to bad problem in mending course, causes and repairs difficulty, affect construction speed.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of polyurethane finish, this finish paint, easy construction, sticking power is good, has the features such as good toolability.
The technical scheme of technical solution problem of the present invention is as follows:
A kind of polyurethane finish, is characterized in that, formulated according to following weight ratio by following component:
Auxiliary agent 5-8 part
Resin 30-50 part
Filler 20-35 part
Flatting silica 5-15 part
Solvent 10-20 part
Solidifying agent 10-25 part.
Further, described auxiliary agent is by anti-sag agent, and dispersion agent, flow agent, defoamer, photostabilizer, catalyzer is 1:1:1:0.5:1.5:0.3 composition according to weight ratio.
Further, described resin is that 1:2 forms by acrylic resin and urethane resin according to weight ratio.
Further, described solidifying agent is hexamethylene diisocyanate biruet.
The invention has the beneficial effects as follows: this invention is with acrylic resin, urethane resin is as membrane-forming agent, urethane resin and hydroxyl acrylic resin with the use of, drying property and all good coating of mechanical property can be obtained, ply adhesion is better, be conducive to the repairing of coating, and the solid of coating divides higher, effectively can reduce the VOC of coating, meet the rigors to environment.Select hexamethylene diisocyanate biruet as solidifying agent, the shock resistance of finish paint, water tolerance is better.Add dispersion agent according to certain ratio in formula, flow agent, the auxiliary agents such as defoamer can play good surface effect, but significantly can reduce coating surface tension, affect the overcoating of paint film, reduce its matching capacity.
