Description
Technical field
The invention belongs to automobile interior decoration technical field of coatings, in particular to a kind of low solvent type high solid for automobile interiors
Coating and preparation method thereof may be directly applied to ABS, the substrates such as ABS/PC, or be applied indirectly to PP by other means, PC and
The acceptable substrates such as PA.
Background technique
Traditional solvent type automobile interior decoration coating in the construction process, must add opposite coating host agent mass fraction 20-
100% diluent is used for auxiliary construction, and in film forming procedure, which volatilizees immediately, thus guarantee coating application and at
Film quality.That is, under current techniques background, construction medium when organic solvent is only used as coating to spray, i.e. adjustment is viscous
Degree, therefore, volatile organic matter (VOC) dosage is big, and discharge amount is big, and environmental pollution is serious.
In recent years, this problem is being paid close attention in industry always, and is attempting to change this single function of organic solvent, to improve
The environmental friendliness of industry copes with the policy direction of energy-saving and emission-reduction.And for a long time, technology path is always to go out from thixotroping angle
Hair keeps stability with high finished product viscosity, the mobility under shearing force is provided with thixotropy, makes to reach and reduce diluent
The purpose of dosage, but the technical limitation is, high thixotropic is simultaneously unstable, while the thinking sheet of some offer high thixotropics
Body is also the product of the high VOC of high energy consumption, such as various organically-modified wax liquors.
Summary of the invention
The first object of the present invention is to provide a kind of low solvent type high solid coating for automobile interiors, by coating group
Divide and optimize, low viscosity linear, crosslinkable resin is added, had not only greatly reduced the dosage of VOC, but also still maintain large arch dam
Amount, in the case where not needing a large amount of extra diluent waters, construction is friendly, and volatile ingredient is few.
The second object of the present invention is to provide a kind of preparation side of above-mentioned low solvent type high solid coating for automobile interiors
Method, coating obtained had not only greatly reduced the dosage of VOC, but also still maintained high solids content, did not needed largely additionally to construct dilute
In the case where releasing agent, construction is friendly, and volatile ingredient is few.
Technical scheme is as follows:
A kind of low solvent type high solid coating for automobile interiors, is made by the raw material for including following parts by weight:
Wherein, the hydroxyl value of the Hydroxylated acrylic resin account for the resin itself can not the solid component of volatile ingredient be
1.8-2.3%, wherein the resin can not volatile component solid component be 49%-51%.
Preferably, the low viscosity linear, crosslinkable resin is the line containing the hydroxyl group that can be reacted with isocyanates
The low branched resins of property, solid component 100%.
Preferably, the dispersion leveling auxiliary agent is polyether modified siloxane, solid component 50%.
Preferably, the toner is goth black No. 4
Preferably, the flatting silica is Degussa OK412
Preferably, the solvent is the mixed solvent of the quality such as butyl acetate, diacetone alcohol and isopropyl acetate.
Preferably, the isocyanate curing agent is that N3390 curing agent is created in Cohan.
Preferably, the diluent is the mixture of the quality such as diacetone alcohol and isopropyl acetate.
The invention also discloses the preparation method of above-mentioned low solvent type high solid coating for automobile interiors, feature exists
In, comprising the following steps:
(1) raw material for taking each parts by weight described in claim 1 is added with stirring Hydroxylated acrylic resin, dispersion levelling agent
With appropriate solvent, 15-20min is stirred, carbon black toner is added and carries out high speed dispersion 30-45min, add low viscosity and linearly may be used
Crosslinked resin, flatting silica and residual solvent stir 15min, strainer filtering packed for standby use；
(2) before constructing, isocyanate curing agent and diluent are respectively after strainer filtering, and step (1) is obtained mixes
Liquid mixes, and obtains low solvent type high solid coating.
Compared with prior art, beneficial effects of the present invention are as follows:
The amount of the volatilizable component during coating application is greatly reduced in the present invention.
One kind low solvent type high solid coating for automobile interiors of the invention largely uses hydroxyl in product different from the past
The route of base acrylic resin, but by being optimized to coating composition, low viscosity linear, crosslinkable resin is added, this can be handed over
Join resin and participate in reaction, had not only greatly reduced the dosage of VOC, but also still maintain high solids content, and ensure that the synthesis of polyurethane
Performance meets TL226-2016 test request.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate this hair
It is bright, rather than limit the scope of protection of the present invention.What those skilled in the art made according to the present invention in practical applications changes
Into and adjustment, still fall within protection scope of the present invention.
The simple thinking for changing water from solvent different from the past for reducing VOC, the present invention had both guaranteed the long-term storage of product itself
Stability (better than aqueous product) is deposited, product itself large arch dam had both been ensure that, and had in turn ensured low viscosity, therefore, there is no need to a large amount of
In the case where additional construction diluent, construction is friendly, and volatile ingredient is few.In addition, automotive interior product uses poly- ammonia since tradition
Chemical constituent of the ester as coating, there is very high comprehensive performance.The present invention also different from previous product largely use hydroxyl
The route of acrylic resin, and the thinking of low viscosity linear, crosslinkable resin has been used, which participates in reaction, does not wave
Hair not only ensure that the comprehensive performance of polyurethane, but also reduce the discharge of VOC.
