Abstract
The present invention discloses a kind of anti scuffing polyurethane matte paint, counts, is mainly made up of following raw material in parts by weight：20 30 parts of polyurethane resin, 10 16 parts of polycarbonate elastomer body resin, 26 33 parts of propandiol butyl ether, 35 parts of dispersant, 12 15 parts of propylene glycol monomethyl ether, 15 parts of methylisobutylketone, 6 10 parts of flatting silica, 12 parts of anti scuffing auxiliary agent, 14 20 parts of UV absorbers.The anti scuffing polyurethane matte paint of the present invention can further enrich the coating material solidified selections in the application of the plastic casing such as automobile or mobile phone of PU, not only wear-resisting scratch-resisting, chemical proofing, durability of such product etc. are all had a distinct increment, also to its feel, anti-pollution can greatly improve, meet the requirement of high-grade automobile or electronic product casing, good economic benefit can be produced.
Description
Technical field
The invention belongs to paint field, and in particular to a kind of anti scuffing polyurethane matte paint.
Background technology
Urethane cures coating is tradition and uses most, the most wide coating system of purposes, except with high-performance at present
Chemical resistance, or both economical type, low baking, the efficient saving energy, coating performance is good after solidification, and being adapted to should
The advantages that for high-speed automated production, so the coating material solidified yield of PU is constantly in stable uptrend in recent years,
Plastic cement products, such as automobile, mobile phone, the application utilization rate of computer swift electron consumer goods shell and dosage also greatly improve.But
With the development of society and the requirement more and more higher of consumer, the performance and appearance requirement of coating also improve therewith.Pursue first
Comfortable feel, secondly anti scuffing effect is good, is not easy to damage, and convenient not trace is arranged in cleaning, durable in use, increases substantially product
Class, so being applied to the new high anti scuffing high-performance PU matte varnish in automobile or consumer electronicses field
It is imperative.
The content of the invention
The technical problem to be solved in the present invention is to overcome the defects of existing, there is provided a kind of anti scuffing polyurethane matte paint.
In order to solve the above-mentioned technical problem, the invention provides following technical scheme：
Anti scuffing polyurethane matte paint, is counted in parts by weight, is mainly made up of following raw material：
Polyurethane resin 20-30 parts,
Polycarbonate elastomer body resin 10-16 parts,
Propandiol butyl ether 26-33 parts,
Dispersant 3-5 parts,
Propylene glycol monomethyl ether 12-15 parts,
Methylisobutylketone 1-5 parts,
Flatting silica 6-10 parts,
Anti scuffing auxiliary agent 1-2 parts,
UV absorbers 14-20 parts.
Further, the anti scuffing auxiliary agent is aralkyl modified methylalkylpolysiloxanes.
Further, the raw material of the anti scuffing polyurethane matte paint also includes the stain resistance auxiliary agent of 1-2 parts by weight.
Further, the stain resistance auxiliary agent is silicone-modified polyacrylate.
Further, the raw material of the anti scuffing polyurethane matte paint also includes the drier of 6-14 parts by weight.
Further, the drier is lutidines.
Propylene glycol monomethyl ether is used in mixed way with propandiol butyl ether to be helped to prevent the erosion to priming paint.
It is coating material solidified in the modeling such as automobile or mobile phone that the anti scuffing polyurethane matte paint of the present invention can further enrich PU
Expect the selection in the application of shell, not only have to wear-resisting scratch-resisting, chemical proofing, durability of such product etc. larger
Lifting, can also greatly improve to its feel, anti-pollution, meet the requirement of high-grade automobile or electronic product casing, can be with
Produce good economic benefit.
Brief description of the drawings
Accompanying drawing is used for providing a further understanding of the present invention, and a part for constitution instruction, the reality with the present invention
Apply example to be used to explain the present invention together, be not construed as limiting the invention.In the accompanying drawings：

The formula of anti scuffing polyurethane matte paint of the present invention is as follows：
First add 1-6 items to add in stirred tank, after stirring, be slow added into the 7th, stir.Redisperse
10-15 min, to fineness 3.5H, 8-11 items are then added successively, are stirred, be eventually adding the 12nd and adjust and glue.
Polyurethane resin needs color inhibition, and ultraviolet lamp burn-in test, 1200kJ paint films aberration is less than 0.03, to acrylic acid
Priming paint has strong adhesive force；Polycarbonate elastomer resin need to have it is not counter stick, constant temperature and humidity occurs without viscous hand, touches flexible
Feel.
The key technical indexes of product of the present invention：
1st, remarkable scratch resistance energy（Anti- more than 2N mechanical performance stroke wound）, nail scratch leave no trace.
2nd, grease, cosmetics and it is other it is dirty be stained with after, it is easy to be rubbed off.
3rd, possesses very smooth hand sense of touch.
3rd, solvent resistant, chemicals-resistant and salt spray test, show unchanged.
4th, UV is exposed to the sun E less than 0.7, and adhesive force is intact.
5th, adhesive force test is more than 4B.
Finally it should be noted that：The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention,
Although the present invention is described in detail with reference to the foregoing embodiments, for those skilled in the art, it still may be used
To be modified to the technical scheme described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic.
Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., it should be included in the present invention's
Within protection domain.
