Embodiment 1

[0064] The powder coating in this example is white and has the following formula:

[0065] Element parts by weight C5 Hydrogenated Petroleum Resin 16 thermoplastic acrylic resin 8 natural rubber powder 5 talcum powder 8 Titanium dioxide 33.5 Quartz sand 5.0 Reflective aluminized ceramic beads 22 Acrylic leveling agent 1 plasticizer 1 Graphene oxide 0.5

Embodiment 2

[0067] The powder coating in this example is white and has the following formula:

[0068] Element parts by weight C5 Hydrogenated Petroleum Resin 20 thermoplastic acrylic resin 6 polyisoprene rubber 3 talcum powder 8 Titanium dioxide 35.5 Quartz sand 3 Reflective aluminized ceramic beads 25 Acrylic leveling agent 1 plasticizer 1 Graphene oxide 0.3

Embodiment 3

[0070] The powder coating in this example is yellow and has the following formulation:

[0071]

[0072]

[0073] The powder coating in embodiment 1 to embodiment 3 adopts following preparation method to prepare:

[0074] C5 petroleum resin fixed bed hydrogenation process;

[0075] The fixed-bed hydrogenation process of C5 petroleum resin is mainly divided into one-stage hydrogenation process and two-stage hydrogenation process, and the present invention adopts the method of two-stage hydrogenation process.

[0076] Specifically: first dissolve C5 petroleum resin and toluene in a mixer, then let the C5 petroleum resin solution enter the heating furnace, mix with hydrogen and enter a hydrogenation reactor for hydrogenation reaction, and the hydrogenated material passes through the separator After cooling and separation, the intermediate product after separating hydrogen and hydrogen chloride gas enters the storage tank, then sends it to the heating furnace for heating, a...

Abstract

The invention discloses a powder coating as well as a preparation method and application thereof. The powder coating is prepared from the following raw materials: thermoplastic resin, graphene substances, filler and reflective microspheres. The thermoplastic resin comprises petroleum resin and / or modified petroleum resin, and the graphene substance comprises at least one of graphene, graphene oxide, reduced graphene oxide and hydrogenated graphene. The powder coating disclosed by the invention has a light reflecting effect no matter in the daytime or at night, the light reflecting microbeads in the coating do not fall off due to friction, and meanwhile, the powder coating does not release VOC (Volatile Organic Compounds) during use, so that the environment-friendly requirement is met.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a powder coating and its preparation method and application. Background technique [0002] The function of road marking paint is to guide the driving of motor vehicles and non-motor vehicles on the road. On the one hand, with the increasing total mileage of roads in our country and the need for maintenance and re-drawing of the original old markings, a large number of markings need to be drawn on the roads. On the other hand, more and more cars are owned, resulting in traffic congestion, and it is urgent to design and implement new road markings to alleviate the current traffic conditions. However, with the frequent occurrence of traffic accidents in recent years, it is necessary to develop all-weather continuous reflective marking paint to better guide traffic. Therefore, it is required that the marking lines must have good visibility both during the day and at nig...
