Masterbatch containing decorative additive
View Patent ↗A masterbatch containing one or more colors of decorative particulate additive is disclosed and is particularly suitable for use in thermoplastic elastomer plastic articles.
1. A masterbatch, comprising:
(a) decorative particulate additive of colored thermoset polymer cut into particulates,
(b) ethylene vinyl acetate,
wherein the decorative particulate additive comprises no more than about 40 weight percent of the masterbatch.
2. The masterbatch of claim 1 , wherein the decorative particulate additive is an additive which provides a sparkling appearance in the color(s) of the particulates when illuminated by visible light.
3. The masterbatch of claim 1 , wherein the decorative particulate additive is composed of two different colors.
4. A polymer compound, comprising:
(a) the masterbatch of claim 1 ; and
(b) thermoplastic elastomer resin of styrenic block copolymer (SBC) or olefin block copolymer (OBC).
5. The compound of claim 4 , wherein the compound further comprises a thermoplastic resin selected from the group consisting of polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyoxymethylene (POM), polyamide (PA), polystyrene (PS), polymethylmethacrylate (PMMA), polyphenylene sulfide (PPS), polylactic acid (PLA), and any combination thereof.
6. The compound of claim 4 , wherein the compound further comprises adhesion promoters; biocides; anti-fogging agents; anti-static agents; bonding, blowing and foaming agents; dispersants; fillers, fibers, and extenders; flame retardants; smoke suppressants; impact modifiers; initiators; lubricants; micas; pigments, colorants and dyes; plasticizers; processing aids; release agents; silane coupling agents, titanates and zirconates coupling agents; slip and anti-blocking agents; stabilizers; stearates; ultraviolet light absorbers; viscosity regulators; PE waxes; catalyst deactivators, or combinations of them.
7. The compound of claim 4 , wherein the amount of decorative particulate additive ranges from about 0.02 to about 2 weight percent of the compound.
8. A method of making a masterbatch of claim 1 , comprising the step of melt-mixing ethylene vinyl acetate and decorative particulate additive to form a masterbatch.
9. The method of claim 8 , further comprising step (b) of melt mixing the masterbatch with polymer resin and optionally other ingredients to form a polymer compound in its finally-shaped form.
10. The method of claim 9 , wherein step (b) uses a technique for final shaping selected from the group consisting of extrusion, molding, spinning, casting, thermoforming, calendering, spinning, or 3D printing.
11. The masterbatch of claim 2 , wherein the decorative particulate additive is composed of two different colors.
12. The compound of claim 4 , wherein the decorative particulate additive is an additive which provides a sparkling appearance in the color(s) of the particulates when illuminated by visible light.
13. The compound of claim 12 , wherein the compound further comprises a thermoplastic resin selected from the group consisting of polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyoxymethylene (POM), polyamide (PA), polystyrene (PS), polymethylmethacrylate (PMMA), polyphenylene sulfide (PPS), polylactic acid (PLA), and any combination thereof.
14. The compound of claim 12 , wherein the compound further comprises adhesion promoters; biocides; anti-fogging agents; anti-static agents; bonding, blowing and foaming agents; dispersants; fillers, fibers, and extenders; flame retardants; smoke suppressants; impact modifiers; initiators; lubricants; micas; pigments, colorants and dyes; plasticizers; processing aids; release agents; silane coupling agents, titanates and zirconates coupling agents; slip and anti-blocking agents; stabilizers; stearates; ultraviolet light absorbers; viscosity regulators; PE waxes; catalyst deactivators, or combinations of them.
15. The compound of claim 12 , wherein the amount of decorative particulate additive ranges from about 0.02 to about 2 weight percent of the compound.
16. The method of claim 8 , wherein the decorative particulate additive is an additive which provides a sparkling appearance in the color(s) of the particulates when illuminated by visible light.
17. The method of claim 16 wherein the step of melt-mixing is step (a) and the method further comprises a step (b), wherein step (b) uses a technique for final shaping selected from the group consisting of extrusion, molding, spinning, casting, thermoforming, calendering, spinning, or 3D printing.
