Cellulosic Fiber Composites Using Protein Hydrolysates and Methods of Making Same

Battelle Memorial Institute

Contact BMI About This Technology

Technology Marketing Summary

This technology relates to cellulosic fiber composites using protein hydrolysates. Cellulosic fiber composites currently use petroleum-derived binders such as isocyanates and phenol formaldehyde. This work fills a need for a new fiber-adhesive, resin binder system that reduces the amount of phenolic and/or isocyanate resin needed.

Description

The cellulosic fiber composites comprise cellulosic material and a resin binder. The resin binder comprises protein hydrolysates and a synthetic resin. The synthetic resin can be phenolic resin, isocyanate resin or combinations thereof. The protein hydrolysates provide a composite with a reduced amount of petrochemicals. The composite contains an amount of resin binder sufficient to bind the cellulosic material. The composite can also contain silicone, silane or a combination thereof. The method employs a low moisture-content mat that does not require drying prior to pressing. Additional methods can be employed to produce finished cellulosic fiber composite articles.

Benefits

• Replacement of petroleum-derived products with natural products
• Ability to use green lumber during bonding
• Significant cost savings with use of soy flour

Applications and Industries

• Traditional compressed cellulosic composites
• Oriented strand board
