Problems solved by technology

[0004] At present, the airless spraying road marking paint in our country cannot achieve premixed glass beads due to technical reasons, so only a layer of glass beads can be sprinkled on the surface of the marking line during construction. The reflective glass beads sprinkled on this layer of surface will soon disappear. Abraded and detached by vehicles, the reflective (effect) time of the marked lines is short, which seriously affects safe driving and poses a safety hazard to driving at night
[0005] There are two main technical problems in the cause of the problem: 1. The glass beads cannot form a uniform and stable distribution state in the coating, and precipitation and agglomeration often occur
2. The rheological properties of the paint are poor, and it cannot be atomized evenly, and it is impossible to implement airless spraying markings
When in use, two groups of resin coatings are mixed with glass microspheres, because only the antifouling ability and reflective effect of glass microspheres are improved, and the adhesion between glass microspheres and resin is not improved, and the prepared coatings are not uniform. coating
[0007] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a new idea and technology to overcome the problem of glass microspheres settling in the coating and spraying unevenly by increasing the adhesion between glass microspheres and resin. Innovation, successfully developed a new spray-on reflective marking paint that meets the requirements of the road surface and pre-mixes reflective glass microspheres

Embodiment 1

[0075] Embodiment 1: a kind of active resin

[0076] 1. Raw materials: 75g methyl methacrylate, 25g butyl acrylate, 5g TPGDA, 6g OPE wax.

[0077] 2. Preparation method:

[0078] Weigh methyl methacrylate, butyl acrylate, and TPGDA according to the proportion, put them into the reactor and control the reaction temperature to 60°C for reaction. When the viscosity is 21-25s, stop the reaction, and then add the OPE wax in the prescribed amount. That is, the active resin component is obtained.

Embodiment 2

[0079] Embodiment 2: a kind of active resin

[0080] 1. Raw materials: 70g methyl methacrylate, 20g butyl acrylate, 3g HDDA, 3g OPE wax.

[0081] 2. Preparation method:

[0082] Weigh methyl methacrylate, butyl acrylate, and HDDA according to the proportion, put them into the reactor and control the reaction temperature to 50°C for reaction. When the viscosity is 21-25s, stop the reaction, and then add the OPE wax in the prescribed amount. That is, the active resin component is obtained.

Embodiment 3

[0083] Embodiment 3: a kind of active resin

[0084] 1. Raw materials: 72g methyl methacrylate, 23g butyl acrylate, 4g TPGDA, 4g OPE wax.

[0085] 2. Preparation method:

[0086] Weigh methyl methacrylate, butyl acrylate, and TPGDA according to the proportion, put them into the reaction kettle and control the reaction temperature to 70°C for reaction. When the viscosity is 21-25s, stop the reaction, and then add the OPE wax in the prescribed amount. That is, the active resin component is obtained.

Abstract

The invention relates to an active resin and a double-component solvent-free airless spraying pavement marking coating. The active resin consists of the following components: methyl methacrylate, butyl acrylate, a monomer of a functionality degree, and OPE (Oxidized Polyethlene Wax). The double-component solvent-free airless spraying pavement marking coating consists of a coating A and a coating Bin a ratio of (1-3):1, wherein the coating A consists of the following components: the active resin, titanium dioxide, a composite anti-settling agent, calcium carbonate, modified glass beads, an initiator and other aids; the coating B comprises the components of the coating A except the initiator which is replaced by an accelerant. A pavement marking line made by using the pavement marking coating provided by the invention has a continuous light reflection function, and has an intense light reflection effect along with the whole service life of the line. A new step is made for the field of pavement marking.

Description

technical field [0001] The invention relates to road surface traffic coatings, in particular to an active resin and a solvent-free and air-free sprayed road marking coating. Background technique [0002] Road markings are the most basic and important part of traffic management facilities. Road markings are the concrete embodiment of national traffic laws and regulations, which guide users to use roads in an orderly manner to promote road traffic safety and improve road operation efficiency. In different nationalities, characters, and geographical locations in China, the information conveyed by various markings and signs seen by road users is consistent. It is a special road graphic language that always reminds drivers how to drive safely. The importance of road markings is therefore obvious. [0003] When night falls, all markings on the road must pass retro-reflective function to reflect the setting of various markings; and markings lacking retro-reflective function are i...
