Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of road marking paint, and particularly relates to a dirt-resistant road marking paint and a preparation method thereof. BACKGROUND

[0002] With the acceleration of traffic road infrastructure construction, the road marking paint plays an important role in controlling and guiding the traffic order of the road surface, improving the driving speed and safety of drivers. The road marking is generally divided into hot-melt road marking and solvent type road marking. The hot-melt road marking produces smoke during construction, polluting the environment. The solvent type road marking has slow drying speed, poor mechanical property and poor dirt resistance.

[0003] The solvent type road marking also has the problems of poor reflectivity, poor water resistance and poor alkali resistance. The existing paint formula needs to be adjusted, and glass beads can be added to increase reflectivity. However, the dispersion uniformity and adhesion of the glass beads in the overall paint formula need to be considered, and the formula also needs to be optimized to achieve the best effect. In addition, compared with the hot-melt road marking, the wear resistance of the solvent type road marking is weakened, and a suitable wear-resistant agent needs to be added to compensate for the insufficient wear resistance. SUMMARY

[0007] The curing agent is a mixture of diethylene triamine and ethyl orthosilicate in a mass ratio of 2:1.

[0008] The wear-resistant agent is a mixture of fine crystalline alumina and polytetrafluoro modified polyethylene wax in a mass ratio of 1:1; the polytetrafluoro modified polyethylene wax is Lubrizol 1778.

[0009] The antifouling agent is a mixture of fluorocarbon surfactant HG-614 and extract of Blidingia sp. in a mass ratio of 3:1.

[0010] The dispersing agent is one or more of zinc stearate, magnesium stearate, sodium allyloxy hydroxypropyl sulfonate, and methacrylate phosphate glycol.

[0011] The anti-settling agent is one or more of bentonite, silicon dioxide, and N,N-methylene (ethylene) bisacrylamide.

[0012] The drying catalyst is one or more of zirconium naphthenate, zinc naphthenate, and manganese naphthenate.

[0013] The toughening agent is one or more of liquid nitrile rubber, methacrylate (vinyl) end group butadiene, butadiene-acrylonitrile, and polyvinyl butyral.

[0014] The preparation method of the antifouling road marking paint comprises the following steps: mixing 50-100 parts of modified bisphenol A type epoxy resin, 40-80 parts of styrene-acrylate copolymer emulsion, 10-15 parts of curing agent, 5-10 parts of wear-resistant agent, 5-10 parts of antifouling agent, 3-6 parts of dispersing agent, 3-5 parts of anti-settling agent, 1-3 parts of drying catalyst, and 2-5 parts of toughening agent, grinding after dispersion to obtain a mixed solution; and using the mixed solution to coat and then uniformly spreading 40-80 parts of glass beads.
