Abstract
Abstract This disclosure relates to a waterproof and weather-resistant adhesive composition for use in the manufacture of corrugated board and its preparation. More specifically, it concerns the preparation of a water-resistant paperboard adhesive containing a resin and a primary, secondary or tertiary amine compound of the formula: ##STR1## wherein R 1 , R 2 , R 3 , and R 4 are the same or different and are hydrogen, alkyl groups of 1 to 3 carbon atoms, or hydroxyalkyl groups of 1 to 3 carbon atoms. This improved starch base adhesive has superior viscosity stability, improved gel temperature, and excellent pot life stability compared to an adhesive made without aminohydroxy compound.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
116 words
A method of making a starch based adhesive comprising the steps of: a. preparing an aqueous alkaline starch carrier containing a portion of the total starch solids, b. mixing therein the remaining portion of the total starch solids, a resin selected from the group consisting of ketone-aldehyde, urea-formaldehyde, phenol-aldehyde, resorcinol-aldehyde, and mixtures thereof, and a primary, secondary or tertiary amine compound of the following formula: ##STR4## wherein R 1 , R 2 , R 3 , and R 4 are the same or different and are hydrogen, alkyl groups of one to three carbon atoms, or hydroxyalkyl groups of one to three carbon atoms, wherein the pH of the adhesive is about 10 to about 12.5.
Claim 2
Independent Claim
116 words
A method of making a starch based adhesive comprising the steps of: a. preparing an aqueous alkaline starch carrier containing a portion of the total starch solids, b. mixing therein the remaining portion of the total starch solids, a resin selected from the group consisting of ketone-aldehyde, urea-formaldehyde, phenol-aldehyde, resorcinol-aldehyde, and mixtures thereof, and a primary, secondary or tertiary amine compound of the following formula: ##STR4## wherein R 1 , R 2 , R 3 , and R 4 are the same or different and are hydrogen, alkyl groups of one to three carbon atoms, or hydroxyalkyl groups of one to three carbon atoms, wherein the pH of the adhesive is about 10 to about 12.5.
Claim 3
Dependent Claim
34 words
The method of claim 1 wherein the starch carrier is prepared by pasting an aqueous alkaline slurry containing a portion of the total starch solids at a temperature of at least about 110° F.
Claim 4
Dependent Claim
130 words
A starch based adhesive comprising: A. about 15% to about 40% starch by weight; B. about 0.2% to about 1.0% sodium hydroxide by weight; C. about 0.1% to about 5.0% resin by weight, wherein the resin is selected from the group consisting of ketone-aldehyde, urea formaldehyde, phenolaldehyde, resorcinol-aldehyde, and mixtures thereof; D. about 0.1% to about 5.0% by weight of a primary, secondary, or tertiary amine compound which is represented by the formula: ##STR5## wherein R 1 , R 2 , R 3 , and R 4 are the same or different and are hydrogen, alkyl groups of one to three carbon atoms, or hydroxyalkyl groups of one to three carbon atoms, E. and about 80% to about 59% water by weight, F. said adhesive being at an alkaline pH.
Claim 5
Dependent Claim
130 words
A starch based adhesive comprising: A. about 15% to about 40% starch by weight; B. about 0.2% to about 1.0% sodium hydroxide by weight; C. about 0.1% to about 5.0% resin by weight, wherein the resin is selected from the group consisting of ketone-aldehyde, urea formaldehyde, phenolaldehyde, resorcinol-aldehyde, and mixtures thereof; D. about 0.1% to about 5.0% by weight of a primary, secondary, or tertiary amine compound which is represented by the formula: ##STR5## wherein R 1 , R 2 , R 3 , and R 4 are the same or different and are hydrogen, alkyl groups of one to three carbon atoms, or hydroxyalkyl groups of one to three carbon atoms, E. and about 80% to about 59% water by weight, F. said adhesive being at an alkaline pH.
Claim 6
Dependent Claim
14 words

Claim 7
Dependent Claim
16 words
The product of claim 3 wherein about 19% (w/w) to about 30% (w/w) starch is used.
Claim 8
Dependent Claim
12 words
The method of claim 1 where in the ketone-aldehyde resin is acetone-formaldehyde.
Claim 9
Dependent Claim
11 words
The adhesive of claim 5 wherein the ketone-aldehyde resin is acetone-formaldehyde.
