Abstract
Soy protein and carbohydrate containing binder compositions are described. The binder compositions may include a carbohydrate, a nitrogen-containing compound, and a soy protein. The binder compositions may also optionally include thickening agents such as modified celluloses and polysaccharides.
Claims23
A soy-containing binder composition comprising:
- a reaction product of a urea compound and a dialdehyde compound;
- a soy protein, wherein the soy protein is chosen from the group consisting of soy flour, defatted soy flour, soy protein concentrate, soy protein isolate, and soy polymer;
- a curing catalyst;
- and
- dextrose that is provided independently of the soy protein, and
- wherein a molar ratio of the reaction product of the urea compound and the dialdehyde compound to the dextrose is 1:2 to 1:50, and
- wherein the soy-containing binder composition is formaldehyde-free.
4 more elements
A blended soy-containing binder composition comprising:
- dextrose,
- a reaction product of a urea compound and an aldehyde-containing compound having the formula:
- wherein R7, R8, R9, and R10 are independently chosen from a hydrogen moiety (H), an alkyl group, an aromatic group, an alcohol group, a ketone group, a carboxylic acid group, an alkoxy group, and wherein at least one of R7, R8, R9, and R10 is an alcohol group,
- a soy protein added independently of the dextrose, and
- a curing catalyst,
- wherein the soy-containing binder composition is formaldehyde-free.
