Description
Technical field
The invention belongs to field of new materials more particularly to a kind of wind power generation blade no-solvent polyurethane materials.
Background technique
There are two major classes at present for wind electricity blade coating, first is that VOC content is poly- in the unification of the bottom surface of 400 to 500 grams per liters
Urethane coating, it is another kind of be by VOC 200 grams per liters or so high solid elastic polyurethane priming paint plus polyurethane finish
Reach the requirement of high durable, resistive sand, resistance to weathering.Coating requires to construct using method of roll coating, has good levelability,
Elasticity is good for film requirement, and intensity is high, ageing-resistant to can achieve 3000 hours.
But the tightening that present environmental requirement is higher and higher, these coating systems are unable to satisfy the discharge of existing VOC
Index request.Although the country expands a large amount of research work to no-solvent polyurethane at present, since some is to belong to
The system of rigidity, is unable to satisfy the requirement of blade protection from performance, and another part is then to belong to viscosity height, working life short (base
This is no more than 20 minutes) rate of drying is too fast, and it applies man-hour requirement and is constructed using two-component high-pressure airless spraying gun, is unable to satisfy
Blade coating uses the requirement of roller application at present, and also some is not then because the factors such as ageing properties or rate of drying can
Meet the requirement of blade coating.
Summary of the invention
To solve the above problems, the present invention provides a kind of wind power generation blade no-solvent polyurethane materials.The present invention
A kind of environment-friendly type coating, VOC content is few, working life 30 minutes or more, roller application can be carried out and have fine levelling
Property；And film elongation percentage, up to 80% or more, breaking strength is in 12MPA or more, and adhesive force is in 10MPA or more, well beyond
The index of existing coating.
To reach above-mentioned technical effect, the technical scheme is that
A kind of wind power generation blade no-solvent polyurethane material, including resin components: 40-80 parts by weight；Titanium dioxide:
10-20 parts by weight；Pigment: 0.1-0.3 parts by weight；
The inorganic filler of silicon-aluminum containing: 3-15；Disperse auxiliary rheological agents 1-3 parts by weight；Ground wetting dispersing agent 0.5-2 weight
Part；Different hydrogen acid ether (hydrogen acid ester): 30-80 parts by weight；
The chemical formula of the resin components is as follows:
Wherein, resin components active hydrogen equivalent weight is between 200 to 350；Viscosity is 400 to 1300mpa.s.
Further to improve, the dispersion auxiliary rheological agents are silicon class wetting agent；The ground wetting dispersing agent is sulfonate
Dispersing agent.
Further to improve, silicon class wetting agent is organic modified polyorganosiloxane；The sulfonic acid dipersant is alkylnaphthalene sulphur
Sour sodium.
Further to improve, the inorganic filler of the sial includes silica and aluminium triphosphate；Silica and three
The mass ratio of poly aluminium phosphate is 1:1.
Further to improve, R is methyl, and X is propyl.
Further to improve, the pigment is black pigment.
Advantages of the present invention:
1. be a kind of environment-friendly type coating, VOC content is few, working life 30 minutes or more, can carry out roller application and
There is fine levelability；
2, film elongation percentage is up to 100% or more, and breaking strength is in 12MPA or more, and adhesive force is in 10MPA or more.
Specific embodiment
Technical solution of the present invention is illustrated below by way of specific embodiment.
Embodiment 1
Make solventfree resin constituent (resin) of the low viscosity containing active hydrogen: active hydrogen equivalent weight is between 200 to 350；
Viscosity is 400 to 1300mpa.s；
According to the difference of X and R, the resin of differential responses speed and different viscosities can be made, so as to design
High-performance, the coating for meeting solvent-free construction.Experiment discovery R can be methyl or ethyl, and X can be ethyl or propyl.
Grey solventless coatings host agent is made using above-mentioned resin Composition, selects aliphatic isocyanates as curing agent:
Resin components: 40-80 parts by weight；
Titanium dioxide: 10-20 parts by weight；
Black pigment: 0.1-0.3 parts by weight；
The inorganic filler of silicon-aluminum containing: 3-15 parts by weight；
Coating commonly uses anti-settling dispersion auxiliary rheological agents: 1-3 parts by weight；
Coating often uses ground wetting dispersing agent: 0.5-2 parts by weight；
Different hydrogen acid ether (hydrogen acid ester) component: 30-80 parts by weight.
By the application of above-mentioned composition, test obtains following performance:
1) VOC content is less than 30 grams per liters.
2) for mixing viscosity 800 to 1200mpa.s, viscosity is not higher than 2000mpa.s after 30 minutes, fully meets roller application
Requirement.
3) and substrate adhesion is not less than 10MPa, elongation percentage 80-120%, breaking strength 15MPa.
4) adhesive force is still not less than 7MPa after can reaching on blade ground salt spray resistance 1500 hours.
It above are only the specifically guiding embodiment of of the invention one, but the design concept of the present invention is not limited to this,
It is all to be made a non-material change to the present invention using this design, it should belong to the behavior for invading protection scope of the present invention.
