Textile Adhesives (Dip Compounds)

配方组成:

*Variable-adjust to pH 10.3
Ph should be 7.0
Dissolve sodium hydroxide in the water. Dissolve resorcinol in sodium
hydroxide modified water. Add formaldehyde and mix five minutes. Let
stand two hours at 75-78'F before combining with latex.
To prepare the latex-resorcinol-formaldehyde fabric treatment compound,
use the following typical recipe and procedure.
Recipe
Formaldehyde (37%)/6.0
Sodium Hydroxide/0.1
Resorcinol/4.1
"Hycar" 1571 (41% solids)/83.9
Resin Masterbatch (above)/91.5
Soft Water/20.6
Soft Water/89.8
Ammonium Hydroxide (28%)*/10.0

配制方法:

Add latex to water. Add resin masterbatch slowly to mixture with constant slow agitation for 5 min. Add ammonium hydroxide to adjust pH to 10.3. Continue agitation at least 10 min. Let compounded dip stand 16 to 18 hr at 75-78'F before using. Maximum shelf life is 96 hr at 75-78'F.
Apply the latex-resorcinol-formaldehyde compound to a fabric by common saturating techniques. Cure from one to 5 min at 285-350'F.
Moisture content of the fabric should be less than 2% after drying.
