Title:
METHOD FOR MIXING LEATHER POWDER WITH RESIN
Document Type and Number:
Japanese Patent JPH01163215
Kind Code:
A
Abstract:

PURPOSE: To provide a leather powder-containing resin material containing homogeneously dispersed fine leather powder therein and useful for coatings, etc., by grinding dry leather powder having a low water content together with a solvent by a wet type grinding machine and subsequently mixing the reground leather powder-containing solvent with a resin material.

CONSTITUTION: Leather powder having a water content of ≤5wt.% is first ground together with a solvent by a wet type grinding machine such as a ball mill. The ground leather powder-containing solvent is subsequently mixed with a resin material such as a polyurethane resin. The above-mentioned leather powder is preferably one obtained by applying a steam heating process to a raw leather material to decompose the triply helical structure of the leather tissue, drying the decomposed leather material to a water content of ≤3wt.% and subsequently grinding the dried leather material by a grinding machine. A solvent capable of dissolving the resin to be mixed with the leather powder is satisfactory for the above-mentioned solvent.
