Abstract
The invention provides protein adhesives and methods of making and using such adhesives. The protein adhesives contain ground plant meal or an isolated polypeptide composition obtained from plant biomass.
Claims58
An adhesive composition comprising:
- (a) from about 1% to about 90% (w/w) of a reactive prepolymer selected from the group consisting of a polyisocyanate-based prepolymer, an epoxy-based prepolymer, and a combination thereof;
- (b) water;
- and
- (c) ground plant meal in an amount sufficient to disperse the reactive prepolymer in the aqueous medium, wherein the ground plant meal is derived from corn, wheat, sunflower, rapeseed, canola, castor, camelina, jatropha, mallow, peanuts, sugarcane begasse, tobacco, whey, or a combination thereof;
- the ground plant meal being present in an amount ranging from about 1% (w/w) to about 50% (w/w) of the adhesive composition.

An adhesive composition comprising:
- (a) from about 1% to about 90% (w/w) of a reactive prepolymer selected from the group consisting of a polyisocyanate-based prepolymer, an epoxy-based prepolymer, and a combination thereof;
- (b) from about 10% to about 98% (w/w) of an isolated polypeptide composition capable of dispersing the reactive prepolymer in an aqueous medium, wherein the isolated polypeptide composition is derived from corn, wheat, sunflower, rapeseed, canola, castor, camelina, jatropha, mallow, peanuts, sugarcane begasse, tobacco, whey, or a combination thereof;
- and
- (c) an additive selected from the group consisting of an agent that improves moisture-resistance, a composite-release promoter, and a pH modulator and, (d) water.
1 more element
A two-part adhesive composition comprising:
- (a) a first part (Part A) comprising from about 0.1% to about 100% (w/w) of a reactive prepolymer, wherein the reactive prepolymer is a polyisocyanate-based prepolymer, an epoxy-based prepolymer, or a combination thereof;
- (b) a second part (Part B) comprising from about 10% to about 99% (w/w) of an isolated polypeptide composition capable of dispersing the reactive prepolymer in an aqueous medium, wherein the isolated polypeptide composition is derived from corn, wheat, sunflower, rapeseed, canola, castor, camelina, jatropha, mallow, peanuts, sugarcane begasse, tobacco, whey, or a combination thereof;
- and
- (c) wherein at least one of Part A or Part B comprises an additive selected from the group consisting of an agent that improves moisture-resistance, a composite-release promoter, and a pH modulator and, (d) water.
