Problems solved by technology
Furthermore, the addition of ammonia reduces the storage stability of the resin
Therefore, ammonia can only be added immediately before applying the resin composition to the nonwoven fibrous material, which is sometimes inconvenient for the user of the resin composition, especially the manufacturer of the insulating material

Embodiment 1
[0026] 880 g of aqueous phenol (90.5%), 251 ml of water and 44 g of NaOH (50%) were combined and heated to 60°C. Subsequently, 1400 g of formalin (55.3 wt % formaldehyde in water) were added slowly over 1 hour, during which time the temperature was raised to 65°C. The mixture was stirred for a further 4 hours at this temperature. Subsequently, the mixture was cooled to 50° C. and 505 g of urea were added. The mixture was stirred for a further 30 minutes at 35°C. 270 grams of the above mixture were combined with 30 grams of glycerin. Continue to stir the mixture until the glycerin is completely dissolved. Resin properties are summarized in Table 1.
[0027] Controlled Experiment 1
[0028] Samples were prepared as described in "Inventive Example" 1, but without glycerol. Resin properties are summarized in Table 1.
[0029] Controlled Experiment 2
[0030] The sample was prepared by combining 270 g of the product obtained in "Control 1" with 30 g of sugar. Stir the resu...

Abstract
The invention relates to a water dilutable resin composition comprising a resin that is a reaction product of an aldehyde and a hydroxyl-aromatic compound, said composition further comprising an amino compound comprising 2 - 6 amino groups and a sugar alcohol, wherein the resin has an initial molar ratio of aldehyde to hydroxyl-aromatic compound from 2.3 to 5.5, a ratio of resin to amino compoundplus sugar alcohol of 45:55 to 70:30 parts by weight, a ratio of amino compound to resin between 20:80 and 50:50 parts by weight and a ratio of sugar alcohol to resin plus amino compound is between 5:95 and 30:70 parts by weight. The invention further relates to a process for the manufacture the resin composition, to the use of the resin composition as a binder material for non-woven fibrous material, in particular insulation materials, and to a process for the manufacture of such insulation material.
Description
field of invention [0001] The present invention relates to a water dilutable resin composition comprising a resin which is the reaction product of an aldehyde and a hydroxyaromatic compound, preferably a phenolic resin, and an amino compound comprising 2 to 6 amino groups, preferably urea, wherein The resin is of the resole type with an initial molar ratio of aldehyde to hydroxyaromatic compound of 2.5-5.5. The invention also relates to a method for the manufacture of said resin composition, the use of the resin composition as a binder material for nonwoven fibrous materials, in particular insulation materials, and a method for the manufacture of such insulation materials. Background technique [0002] Phenolic binder materials, especially phenolic resins, are well known alkaline chemistries for classical insulating resin compositions. The problem with these chemicals is that both phenol and formaldehyde are toxic and have relatively high vapor pressures, resulting in the r...
