A solvent-free process is used to make moldable plastic explosives or moldable plastic explosive simulant products.
대표청구항▼
1. A solvent-free process to make mouldable plastic explosive simulant products, comprising the steps of: (a) mixing at room temperature the following ingredients to form a substantially homogeneous mixture: (1) a powdered explosive or inert simulant thereof;(2) a viscous liquid binder;(3) optionall
1. A solvent-free process to make mouldable plastic explosive simulant products, comprising the steps of: (a) mixing at room temperature the following ingredients to form a substantially homogeneous mixture: (1) a powdered explosive or inert simulant thereof;(2) a viscous liquid binder;(3) optionally, a plasticizer sufficient to increase the plasticity and malleability of the product without substantially negatively affecting surface adhesion of the product;(4) optionally, a rheology modifier sufficient to increase thixotropy, increase resistance to sagging, and minimize separation of the liquid binder from the powdered explosive or simulant;(5) optionally, a coloring agent sufficient to impart visually detectable, permanent, indelible color to the product;(6) optionally, a volatile chemical taggant sufficient to be detectable in the product by ion mobility spectrometer or by detector canine, and survive the process to retain detectability in the product;with the proviso that no solvent is used in the process;(b) manipulating the mixture to a predetermined shape and size by extruding and cutting, or pressing the mixture into moulds, and;(c) optionally, packaging the resultant shaped and sized product for shipping. 2. The process of claim 1 wherein ingredient (1) is the powdered explosive that is RDX, PETN, HMX, or TNT. 3. The process of claim 1 wherein ingredient (1) is the simulant that is pentaerythritol, urea or monosodium glutamate. 4. The process of claim 1 wherein the viscous liquid binder is selected from (a) liquid isoprene rubber; (b) liquid natural rubber or synthetic rubber, (c) liquid polyisobutylene, (d) polybutadiene, (e) liquid polyamides based on dimer acids and diamines, and (f) nonpolymeric liquid resins or rosin esters. 5. The process of claim 1 wherein the viscous liquid binder is a liquid isoprene rubber. 6. The process of claim 1 wherein the viscous liquid binder is a liquid natural rubber or synthetic rubber. 7. The process of claim 1 wherein the viscous liquid binder is a liquid polyisobutylene. 8. The process of claim 1 wherein the viscous liquid binder is a polybutadiene. 9. The process of claim 1 wherein the viscous liquid binder is a liquid polyamide based on dimer acids and amines. 10. The process of claim 1 wherein the viscous liquid binder is a nonpolymeric liquid resin or rosin ester. 11. The process of claim 1 wherein the plasticizer is included and is dioctyl sebacate or dioctyl adipate. 12. The process of claim 1 wherein the rheology modifier is included and selected from synthetic clays, natural clays, coated fumed silica, chemically-modified natural clays, synthetic silicates, natural or synthetic organic polymers and gums. 13. The process of claim 1 wherein the rheology modifier is included and is Zeothix 265. 14. The process of claim 1 wherein ingredient (1) is the simulant, and the taggant is included and is 2,3-dimethyl-2,3-dinitrobutane (DMNB) or ethylene glycol dinitrate (EGDN). 15. The process of claim 1 wherein the coloring agent is included and the colour is Sudan IV, orange, carbon black, or Solfort yellow. 16. The process of claim 1 wherein the plasticizer is included and the rheology modifier is included. 17. The process of claim 1 wherein the plasticizer is included, the rheology modifier is included, and the coloring agent is included. 18. The process of claim 1 wherein the plasticizer is included, the rheology modifier is included, and the coloring agent is included, wherein: the viscous liquid binder is selected from (a) liquid isoprene rubber; (b) liquid natural rubber or synthetic rubber, (c) liquid polyisobutylene, (d) polybutadiene, (e) liquid polyamides based on dimer acids and diamines, and (f) nonpolymeric liquid resins or rosin esters;the plasticizer is dioctyl sebacate or dioctyl adipate;the rheology modifier is selected from synthetic clays, natural clays, coated fumed silica, chemically-modified natural clays, synthetic silicates, natural or synthetic organic polymers and gums; andthe colour is Sudan IV, orange, carbon black, or Solfort yellow. 19. The process of claim 1 wherein the plasticizer is included, and the rheology modifier is included, and the coloring agent is included, wherein: the viscous liquid binder is selected from (a) liquid isoprene rubber; (b) liquid natural rubber or synthetic rubber, (c) liquid polyisobutylene, (d) polybutadiene, (e) liquid polyamides based on dimer acids and diamines, and (f) nonpolymeric liquid resins or rosin esters;the plasticizer is dioctyl sebacate or dioctyl adipate;the rheology modifier is selected from synthetic clays, natural clays, coated fumed silica, chemically-modified natural clays, synthetic silicates, natural or synthetic organic polymers and gums;the colour is Sudan IV, orange, carbon black, or Solfort yellow, andthe ingredient (1) is the powdered explosive that is RDX, PETN, HMX, or TNT. 20. The process of claim 1 wherein the plasticizer is included, the rheology modifier is included, the taggant is included, and the coloring agent is included, wherein: the viscous liquid binder is selected from (a) liquid isoprene rubber; (b) liquid natural rubber or synthetic rubber, (c) liquid polyisobutylene, (d) polybutadiene, (e) liquid polyamides based on dimer acids and diamines, and (f) nonpolymeric liquid resins or rosin esters;the plasticizer is dioctyl sebacate or dioctyl adipate;the rheology modifier is selected from synthetic clays, natural clays, coated fumed silica, chemically-modified natural clays, synthetic silicates, natural or synthetic organic polymers and gums;the taggant is 2,3-dimethyl-2,3-dinitrobutane (DMNB) or ethylene glycol dinitrate (EGDN);the colour is Sudan IV, orange, carbon black, or Solfort yellow; andthe ingredient (1) is the simulant that is pentaerythritol, urea or monosodium glutamate.
