Embodiment Construction

[0031] One, the present invention will be described in more detail below in conjunction with the specific technical details among the present invention:

[0032] a. The solvent used in the ultraviolet photosensitive reversible discoloration coating of the present invention is tetrahydrofuran (THF), and its pH value is 5. THF is an important raw material for organic synthesis, and is a solvent with excellent performance. The mixed emulsion composed of bimolecular polyurethane resin and polyurethane diluent is the resin material of the coating. The pigments and fillers are UV photosensitive reversible coloring pigments and fillers configured in strict proportion. The auxiliary agent is dicyclopentenyloxyethyl acrylate (DPOA), which is non-volatile and environmentally friendly.

[0033] b. When preparing this kind of paint, attention should be paid to the order of adding various mixtures, the time of stirring, and the timing of adding various additives. The intermediate products...

Abstract

The invention discloses a preparation method of an ultraviolet light-sensitive reversible color-changing coating for road pavement identification, and a practical application of the ultraviolet light-sensitive reversible color-changing coating for road pavement identification in road engineering. The preparation method comprises the following steps: grinding op powder, PS plastic particles, fluorescent powder and titanium dioxide powder to 6-12 [mu] m, mixing to prepare an ultraviolet light sensation reversible color-changing pigment filler, adding the pigment filler into a mixed emulsion formed by mixing bimolecular polyurethane resin and a polyurethane diluent according to a ratio of 1.5: 1, heating to 40 DEG C at a constant temperature, pre-stirring, adding a tetrahydrofuran (THF) solvent, a coalescing agent (dicyclopentenyl oxyethyl acrylate), a dispersing agent (triethylhexyl phosphoric acid) and a modifier (an antioxidant and a light stabilizer), and fully stirring to obtain thecoating. The method has the advantages of simple preparation instrument, stable property of the prepared coating, obvious color effect of the coating and the like, is simple to apply in road engineering, and can easily meet the engineering requirements in the existing road engineering.

Description

technical field [0001] The invention relates to a preparation method of an ultraviolet photosensitive reversible discoloration paint and the practical application of the ultraviolet photosensitive reversible discoloration road surface marking in road engineering. Background technique [0002] In the weather with strong light intensity, driving a car facing the sun for a long time, when driving on a white road such as cement concrete, it is easy to cause glare due to the reflection of the road surface, and at the same time, visual fatigue will soon occur and affect driving safety. [0003] With the improvement of people's living standards, people have put forward higher requirements for all aspects of daily life. When driving a car, in addition to the requirements for driving stability and other comfort, it is also hoped that they can have when driving. A pleasing driving experience. [0004] In recent years, people's awareness of the hazards of ultraviolet rays has improved...
