Abstract

An aqueous binder composition for mineral fibers which comprises at least one polyelectrolytic hydrocolloid.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An aqueous binder composition, wherein the composition is suitable for binding mineral fibers, comprises one or more polyelectrolytic hydrocolloids and is capable of being cured at a temperature of not higher than 95° C. 
     
     
         2 . The binder composition of  claim 1 , wherein the one or more polyelectrolytic hydrocolloids comprise one or more hydrocolloids selected from gelatin, pectin, alginate, carrageenan, gum arabic, xanthan gum, and cellulose derivatives. 
     
     
         3 . The binder composition of  claim 1 , wherein one of the one or more polyelectrolytic hydrocolloids is gelatin. 
     
     
         4 . The binder composition of  claim 1 , wherein the composition comprises at least two polyelectrolytic hydrocolloids, one polyelectrolytic hydrocolloid being gelatin and at least one other polyelectrolytic hydrocolloid being selected from pectin, alginate, carrageenan, gum arabic, xanthan gum, and cellulose derivatives. 
     
     
         5 . The binder composition of  claim 4 , wherein gelatin is present in a concentration of from 10 to 95 wt.-%, based on a weight of the at least two polyelectrolytic hydrocolloids. 
     
     
         6 . The binder composition of  claim 1 , wherein the composition comprises at least two polyelectrolytic hydrocolloids which have complementary charges. 
     
     
         7 . The binder composition of  claim 1 , wherein the composition comprises one or more proteins of animal origin and wherein the composition further comprises at least one enzyme selected from transglutaminase (EC 2.3.2.13), protein disulfide isomerase (EC 5.3.4.1), thiol oxidase (EC 1.8.3.2), polyphenol oxidase (EC 1.14.18.1), catechol oxidase, tyrosine oxidase, phenoloxidase, lysyl oxidase (EC 1.4.3.13), and peroxidase (EC 1.11.1.7). 
     
     
         8 . The binder composition of  claim 1 , wherein the composition consists essentially of water, the one or more polyelectrolytic hydrocolloids; optionally at least one oil; optionally at least one pH-adjuster; optionally at least one crosslinker; optionally at least one anti-fouling agent; optionally at least one anti-swelling agent. 
     
     
         9 . An aqueous binder composition, wherein the composition is suitable for binding mineral fibers and comprises at least two polyelectrolytic hydrocolloids, one polyelectrolytic hydrocolloid being gelatin and at least one other polyelectrolytic hydrocolloid being selected from pectin, alginate, carrageenan, gum arabic, xanthan gum, and cellulose derivatives. 
     
     
         10 . The binder composition of  claim 9 , wherein gelatin is present in a concentration of from 10 to 95 wt.-%, based on a weight of the at least two polyelectrolytic hydrocolloids. 
     
     
         11 . The binder composition of  claim 9 , wherein the composition comprises one or more proteins of animal origin and wherein the composition further comprises at least one enzyme selected from transglutaminase (EC 2.3.2.13), protein disulfide isomerase (EC 5.3.4.1), thiol oxidase (EC 1.8.3.2), polyphenol oxidase (EC 1.14.18.1), catechol oxidase, tyrosine oxidase, phenoloxidase, lysyl oxidase (EC 1.4.3.13), and peroxidase (EC 1.11.1.7). 
     
     
         12 . An aqueous binder composition, wherein the composition is suitable for binding mineral fibers and consists essentially of water, one or more polyelectrolytic hydrocolloids; optionally at least one oil; optionally at least one pH-adjuster; optionally at least one crosslinker; optionally at least one anti-fouling agent; optionally at least one anti-swelling agent. 
     
     
         13 . The binder composition of  claim 12 , wherein the one or more polyelectrolytic hydrocolloids comprise one or more hydrocolloids selected from gelatin, pectin, alginate, carrageenan, gum arabic, xanthan gum, and cellulose derivatives. 
     
     
         14 . The binder composition of  claim 12 , wherein one of the one or more polyelectrolytic hydrocolloids is gelatin. 
     
     
         15 . The binder composition of  claim 12 , wherein the composition comprises at least two polyelectrolytic hydrocolloids, one polyelectrolytic hydrocolloid being gelatin and at least one other polyelectrolytic hydrocolloid being selected from pectin, alginate, carrageenan, gum arabic, xanthan gum, and cellulose derivatives. 
     
     
         16 . The binder composition of  claim 15 , wherein gelatin is present in a concentration of from 10 to 95 wt.-%, based on a weight of the at least two polyelectrolytic hydrocolloids. 
     
     
         17 . A mineral wool product, wherein the product comprises mineral fibers bonded by a cured binder composition of  claim 1 . 
     
     
         18 . A mineral wool product, wherein the product comprises mineral fibers bonded by a cured binder composition of  claim 2 . 
     
     
         19 . A method for producing a mineral wool product, wherein the method comprises contacting mineral fibers with the binder composition of  claim 1  and curing the binder composition. 
     
     
         20 . A method for producing a mineral wool product, wherein the method comprises contacting mineral fibers with the binder composition of  claim 2  and curing the binder composition.
