摘要
(WO2020/150337) Thermoplastic compositions useful for roadway markings may be produced using a continuous systems and process methods that can reduce costs and improve product quality. Systems may comprise a feed system (100) comprising a plurality of feeders and a mixing system (400) comprising a mixer (440) and a smoothing system (401). Each feeder may be configured to discharge a material (101) at a feed rate according to a selected product formulation. The mixing system (400) may be configured to receive, heat, and combine the materials (101) to produce a thermoplastic material, and discharge the thermoplastic material at a determined discharge rate.

(WO2020/150337) WHAT IS CLAIMED IS: 1. A system for producing thermoplastic material for roadway markings, the system comprising:   a feed system comprising a plurality of feeders, each feeder configured to discharge a material at a feed rate according to a selected product formulation; and   a mixing system configured to receive, heat, and combine the materials to produce a thermoplastic material, and discharge the thermoplastic material at a determined discharge rate. 2. The system of claim 1, wherein each feeder comprises a vibratory conveyer, a screw conveyer, or a liquid charge line. 3. The system of claim 1, wherein the feed rate of at least one material is controlled by a weight differential of the feeder over time. 4. The system of claim 1, wherein the feed rate of at least one material is controlled by a volumetric flowrate from the feeder. 5. The system of claim 1, further comprising a transport system configured to receive the materials from the feed system and transport the materials to the mixing system. 6. The system of claim 5, wherein the transport system comprises a plurality of buckets, a belt conveyer, or a pneumatic conveyer. 7. The system of claim 1, wherein the mixing system comprises a mixer and a smoothing system comprising a vibratory conveyer or screw conveyer,   wherein the smoothing system is configured to receive the materials from the feed system or transport system and feed the materials to the mixer. 8. The system of claim 7, wherein the mixer comprises a single screw mixer or a twin screw mixer. 9. The system of claim 7, wherein the mixer comprises more than one heating zone. 10. The system of claim 1, wherein the mixing system heats the materials to a temperature of 150 °F to 450 °F. 11. The system of claim 1, further comprising a finishing system configured to receive the discharged thermoplastic material from the mixing system. 12. The system of claim 1, further comprising a control system configured to monitor process performance, product quality parameters, or combinations thereof, and adjust the feed rate of one or more of the feeders based on the discharge rate from the mixing system, the selected product formulation, or combinations thereof. 13. A method for producing thermoplastic composition for roadway markings comprising: charging a feed system comprising a plurality of feeders with components of the thermoplastic composition;   discharging the components from the feeders at a determined feed rate;   feeding the components to a mixing system;   mixing and heating the components in the mixing system; and   discharging the thermoplastic composition. 14. The method of claim 13, further comprising adjusting the feed rate of the components based on the discharge rate of the thermoplastic composition. 15. The method of claim 13, further comprising transporting the components from the feed system to the mixing system by a transport system comprising one or more of a pneumatic conveyer, belt conveyer, or bucket conveyer. 16. The method claim 13, wherein the mixing system comprises a mixer and a smoothing system. 17. The method of claim 16, further comprising blending at least a portion of the components in the smoothing system prior and feeding the blended components to the mixer. 18. The method of claim 13, further comprising performing inline quality analysis and adjusting a feed rate of at least one component according to an inline quality analysis result. 19. The method of claim 13, further comprising heating the mixing system to a temperature of between 200 °F and 800 °F. 20. The method of claim 13, wherein the components of the thermoplastic composition comprise:   at least 3 weight percent polypropylene/polyethylene copolymer;   at least 18 weight percent binder;   at least 20 percent intermix of inorganic filler; and   at least one of:   at least 1 weight percent of a polyethylene homopolymer wax,   at least 1 weight percent alkyd resin and soybean oil mixtures,   at least 0.5 weight percent of a UV stabilizing compound,   at least 1 weight percent of an alkyd resin modified glyceryl phthalate, or at least 1 weight percent of a polyurethane.
