Binding agent for producing road markings ready quickly for traffic

1. A method of producing a trafficway marking, the method comprising:

applying a cold plastic to a trafficway surface, to obtain the trafficway marking,

wherein, in less than 5 minutes after the applying, the trafficway marking can withstand the passage of traffic, and

said cold plastic is a cold plastic comprising:

from 15% to 45% by weight of a reactive resin;

from 1% to 5% by weight of a mixture comprising an initiator;

from 7% to 15% by weight of an inorganic pigment; and

from 50% to 60% by weight of a mineral filler

wherein

said reactive resin, comprises:

from 20% to 30% by weight of at least one crosslinking agent selected from the group consisting of allyl (meth)acrylate, 1,4-butanediol di(meth)acrylate, tetraethylene glycol di(meth)acrylate, triethylene glycol di(meth)acrylate, and trimethylolpropane tri(meth)acrylate, with the proviso that the lower limit of said at least one crosslinking agent is 6% by weight, relative to the amount of the cold plastic, when the amount of reactive resin in the cold plastic is from 15 to 30% by weight.

from 30% to 40% by weight of a monomer component comprising at least one monomer selected from the group consisting of an alkyl (meth)acrylate of an alcohol having from 1 to 40 carbon atoms, an aryl (meth)acrylate, a mono (meth)acrylate of an ether having from 5 to 80 carbons, an α,β-unsaturated monocarboxylic acid, an α,β-unsaturated dicarboxylic acid, a hydroxyalkyl (meth)acrylate, a (meth)acrylamide, an amino alkyl (meth)acrylate, glycidyl (meth)acrylate, and a silyl-functional (meth)acrylate;

from 10% to 20% by weight of a urethane (meth)acrylate, wherein the urethane (meth)acryalate comprises at least two (meth)acrylate functions linked together with a urethane group;

from 15% to 25% by weight of a prepolymer comprising at least one selected from the group consisting of a polyester and a poly(meth)acrylate;

from above 0% to 5% by weight of an accelerator, which is a tertiary, aromatically substituted amine; and

optionally, an auxiliary.

2. The method of claim 1 , wherein, in less than 2 minutes after the applying, the trafficway marking can withstand the passage of traffic.

3. The method of claim 1 , further comprising, prior to, during, or after the applying:

adding glass beads to the cold plastic.

4. The method of claim 1 , wherein said cold plastic comprises

from 15% to 45% by weight of the reactive resin;

from 1% to 5% by weight of a mixture comprising an initiator;

from 7% to 15% by weight of titanium dioxide; and

from 50% to 60% by weight of a mineral filler, wherein

the accelerator is present in an amount of from above 0% to 5% by weight of and is a tertiary, aromatically substituted amine.

5. The method of claim 1 , wherein said cold plastic comprises

from 20% to 30% by weight of at least two crosslinking agents selected from the group consisting of allyl (meth)acrylate, 1,4-butanediol di(meth)acrylate, tetraethylene glycol di(meth)acrylate, triethylene glycol di(meth)acrylate, and trimethylolpropane tri(meth)acrylate.

6. The method of claim 1 , wherein said cold plastic comprises from 20% to 30% by weight of a mixture of 1,4-butanediol dimethacrylate and triethylene glycol dimethacrylate.

7. The method of claim 1 , wherein the tertiary, aromatically substituted amine is selected from the group consisting of N,N-dimethyl-p-toluidine, N,N-bis(2-hydroxyethyl)-p-toluidine, N,N-bis(2-hydroxypropyl)-p-toluidine, and a combination thereof.

8. The method of claim 1 , wherein the tertiary, aromatically substituted amine is selected from the group consisting of N,N-dimethyl-p-toluidine, N,N-bis(2-hydroxyethyl)-p-toluidine, N,N-bis(2-hydroxypropyl)-p-toluidine, and a combination thereof, present in an amount of from above 0% to 3% by weight.
