Abstract
Treated aldehyde-based resins containing one or more polyamines and methods for making and same. The treated aldehyde-based resin can be or include an aldehyde-based resin and a polyamine. The polyamine can be or include one or more aromatic polyamines, one or more poly(C2-C5 alkylene) polyamines, or a mixture thereof. The treated aldehyde-based resin can include about 0.05 wt % to about 10 wt % of the polyamine, based on a solids weight of the aldehyde-based resin.
Claims20
A treated aldehyde-based resin, comprising:
- an aldehyde-based resin;
- a polyamine comprising an aromatic polyamine, wherein the aromatic polyamine comprises 1,3-diaminobenzene, 1,4-diaminobenzene, 1,3-xylylenediamine, 1,4-xylylenediamine, 3,4′-diaminodiphenyl ether, 4,4′-diaminodiphenyl ether, an isomer thereof, or any mixture thereof, wherein the treated aldehyde-based resin comprises about 0.05 wt % to 0.7 wt % of the polyamine, based on a solids weight of the aldehyde-based resin;
- and
- an additive comprising a wax, a dibasic ester, or a mixture thereof.
A method for making a treated aldehyde-based resin, comprising:
- combining an aldehyde-based resin, a polyamine, and an additive to produce a mixture, wherein the polyamine comprises an aromatic polyamine, wherein the aromatic polyamine comprises 1,3-diaminobenzene, 1,4-diaminobenzene, 1,3-xylylenediamine, 1,4-xylylenediamine, 3,4′-diaminodiphenyl ether, 4,4′-diaminodiphenyl ether, an isomer thereof, and wherein the mixture comprises about 0.05 wt % to 0.7 wt % of the polyamine, based on a solids weight of the aldehyde-based resin, and wherein the additive comprises a wax, a dibasic ester, or a mixture thereof;
- heating the mixture to a temperature of about 110° C. to about 200° C. to produce the treated aldehyde-based resin;
- and
- cooling the treated aldehyde-based resin to a temperature of less than 50° C.
A method for making a treated aldehyde-based resin, comprising:
- heating a solid aldehyde-based resin to a temperature of about 110° C. to about 200° C. to produce a molten aldehyde-based resin;
- combining the molten aldehyde-based resin and a polyamine to produce the treated aldehyde-based resin, wherein:
- the polyamine comprises an aromatic polyamine, a poly(C2-C5 alkylene) polyamine, or a mixture thereof,
- the treated aldehyde-based resin comprises about 0.05 wt % to about 10 wt % of the polyamine, based on a solids weight of the aldehyde-based resin,
- the polyamine is a solid when combined with the molten aldehyde-based resin, and
- the molten aldehyde-based resin and the polyamine are at a temperature of about 110° C. to about 200° C. when combined with one another;
- and
- cooling the treated aldehyde-based resin to a temperature of less than 50° C.
A method for making a treated aldehyde-based resin, comprising:
- combining formaldehyde and a reagent to produce a first mixture, wherein the reagent comprises phenol, urea, or a mixture thereof;
- heating the first mixture to produce an aldehyde-based resin;
- combining the aldehyde-based resin and an additive to produce a second mixture, wherein the additive comprises a wax, a dibasic ester, or a mixture thereof;
- combining the second mixture and a polyamine to produce a third mixture, wherein the polyamine comprises an aromatic polyamine, a poly(C2-C5 alkylene) polyamine, or a mixture thereof, and wherein the third mixture comprises about 0.05 wt % to 0.7 wt % of the polyamine, based on a solids weight of the aldehyde-based resin;
- heating the third mixture to a temperature of about 110° C. to about 200° C. for about 5 minutes to about 90 minutes to produce the treated aldehyde-based resin;
- and
- cooling the treated aldehyde-based resin to a temperature of less than 50° C. to solidify the treated aldehyde-based resin.
