What is Acrylic Resin Road Surface Marking?


Acrylic resin is the general name of acrylic acid, methacrylate and its derivative polymers.clear acrylic resin is to (meth) acrylate, styrene as the main body, and other income of acrylate copolymer of acrylic resin thermoplastic or thermosetting resin coating, coating or acrylic radiation.


The characteristics of traffic marking paint

Thermoplastic acrylic resin does not occur in the process of film crosslinked further, so its relative molecular weight is bigger, it has good light colour retention, resistance to water, chemical resistance, quick drying, construction is convenient, easy construction, painting and rework preparation of aluminum powder paint aluminum powder whiteness, good location.Thermoplastic acrylic resin has been widely used in automotive, electrical, mechanical and construction fields.

Thermosetting acrylic resin refers to the structure of a certain functional groups, in the paint by amino resin, epoxy resin, polyurethane and join the reticular structure of functional groups such as reaction, thermosetting resin generally low relative molecular weight.Thermosetting acrylic coatings have excellent fullness, gloss, hardness, solvent resistance, weather resistance, no discoloration and no yellowing during high temperature baking.The most important application is to combine with amino resin to make amino-acrylic baking paint, which is widely used in automobile, motorcycle, bicycle, coil steel and other products.


Classification of road marking paint

According to the mode of production, the classification can be divided into:

1. Emulsion polymerization is formed by reaction and polymerization of monomers, initiators and distilled water. Generally, the resulting resin is a emulsion with a solid content of 50%, which is a latex solution with about 50% water.The resulting emulsion is usually milky white and bluish (dindar phenomenon), and the vitrifying temperature is designed according to the FOX formula.Therefore, this type of emulsion has a large molecular weight, but the solid content is generally 40-50%.The production industry requires accurate control because of the use of water as a solvent, environmentally friendly emulsion.

2. Suspension polymerization is a relatively complex production process, which is used as a method to produce solid resin.Solid acrylic resin was polymerized with methylene acrylate.Methyl-bearing acrylate is usually a functional group, and its polymerization reaction in the reaction kettle is not easy to control, and it is easy to stick to the pot.The process is to put monomers, initiators and auxiliaries into the reactor and then put them into distilled water.After a certain time and temperature reaction before washing, then drying, filtration, etc.The production control of its products is strict.If in the middle of which link can not be done, its products will have a certain impact.It's the difference between the color and the molecular weight.

3. Bulk polymerization is an efficient production process.Process is put the raw material in a special plastic film, and then reaction into plugs, take out, filter, and its purity is produced by the method of this kind of solid acrylic resin all can be the highest in the method of production, product stability is also one of the best, and its shortcomings is full.By bulk polymerization of acrylic resin for solvent solubility is not strong, sometimes the same monomer the same matching with suspension polymerization is difficult to dissolve several times, and pigment dispersion and suspension polymerization of acrylic resin.

4. Other polymerization methods are used for solvent reaction. When the reaction is carried out, the intermediates are taken down together with the solvent, and the solvent is removed after the reactor is well prepared.
