Abstract
A flame-proof vulcanized polymer composition includes as a polymer component a halogen-free olefinic M-group elastomer with a saturated main chain at an amount of greater than 50 Parts per Hundred Rubber (phr) with respect to polymer components, a halogen-free water-releasing flame retardant or a combination of different halogen-free water-releasing flame retardants at an amount of in total 30 to 130 phr and a mineral oil plasticizer having an amount of less than or equal to 50 phr. Further disclosed are a method for producing the flame retardant vulcanized polymer composition, a flame-retardant article and an elastic flame-proof composite element.
Claims32
A flame retardant, vulcanised polymer composition, comprising:
- at least one halogen-free olefinic M-group elastomer as a polymer component with a saturated main chain at an amount of greater than 70 phr with respect to polymer components;
- wherein the at least one of the polymer component is single-phase and homogenous;
- at least one halogen-free water-releasing metal hydrate or a combination of different halogen-free water-releasing metal hydrates as flame retardant at an amount of in total 60 to less than 100 phr;
- and
- a mineral oil plasticiser in an amount of less than or equal to 50 phr;
- wherein a vulcanized matrix is formed by a sulphur or a sulphur-containing cross-linking system such that the cross-linking system extends over the entire matrix and is completely interspersed through the matrix;
- and
- wherein the entire composition is halogen-free.
A composition, comprising:
- a halogen-free olefinic M-group elastomer as a polymer component with a saturated main chain at an amount of greater than 50 phr with respect to polymer components;
- a halogen-free water-releasing flame retardant or a combination of different halogen-free water-releasing flame retardants at an amount of in total 30 to less than 100 phr;
- and
- a mineral oil plasticiser having an amount of less than or equal to 50 phr,
- wherein the composition is formed into a matrix by a sulphur or a sulphur-containing cross-linking system such that the cross-linking system extends over the entire vulcanised matrix and is completely interspersed through the matrix.
An elastic flame-proof composite element, suitable for damping oscillations and for suspension, comprising:
- a base body made from rubber and provided with a coating of a composition including a halogen-free olefinic M-group elastomer as a polymer component with a saturated main chain at an amount of greater than 50 phr with respect to polymer components, a halogen-free water-releasing flame retardant or a combination of different halogen-free water-releasing flame retardants at an amount of in total 30 to less than 100 phr and a mineral oil plasticiser having an amount of less than or equal to 50 phr, wherein a vulcanised matrix on a mixture matrix is formed by a sulphur or a sulphur-containing cross-linking system which extends over the entire vulcanised matrix and is completely interspersed through the matrix, said composition coating the base body at least partially or in sections, on an outer surface thereof, optionally, over the entire outer surface thereof.
