Abstract
This invention is directed to an extruded product, extrudable compound, and an extrusion method using a polymer, a cellulosic fiber, and at least one lubricant selected from the group consisting of ethoxylated esters of hydantoins, ethoxylated esters of sorbitol or sorbitan, or N, N′-bisalkanoylethylenediamines containing from 8 to 14 carbons of the alkanoyl group and compositions manufactured through such processes which simulate conventional wood products. The N,N′-bisalkanoylethylenediamines are new compositions of matter containing from 8 to 14 carbons of the alkanoyl group having a particle size range from about 90 to 150 μm, preferably from about 120 to 140 μm.
Claims19
A polymer cellulosic fiber composition comprising an admixture of about 30 to 70 wt. % high density polyethylene, about 70 to 30 wt. % oak, and about 2 to 7 wt. % of a lubricant selected from:
- polyoxyethylene (POE) 15 di(2-hydroxyethyl-)5,5 dimethyl hydrazine (DMH) distearate, POE 15 di(2-hydroxylethyl-)5,5 DMH monooleate, a mixture of N,N′-bisoctanoylethylenediamine and N,N′-bisdecanoylethylenediamine, POE 20 sorbitan monostearate, and POE 20 sorbitan monooleate.
A polymer cellulosic fiber composition comprising an admixture of about 30 to 70 wt. % of a polymer selected from the group consisting of high density polyethylene, polypropylene and combinations thereof;
- about 70 to 30 wt. % of cellulosic fiber, wherein the cellulosic fiber is selected from pine, maple, oak, and combinations thereof;
- and about 2 to 7 wt. % lubricant, wherein the lubricant is mixtures of N,N′-bisoctanoylethylenediamine, N,N′-bisdecanoyl-ethylenediamine, N,N′-bisdodecanoylethylenediamine and N,N′-bistetradecanoylethylene-diamine.
A polymer cellulosic fiber composition comprising an admixture of about 30 to 70 wt. % high density polyethylene, about 70 to 30 wt. % pine, and about 2 to 7 wt. % lubricant, wherein the lubricant is selected from polyoxyethylene (POE) 15 di(2-hydroxyethyl-)5,5 dimethyl hydrazine (DMH) distearate, POE 15 di(2-hydroxylethyl-)5,5 DMH monooleate, POE 20 sorbitan monostearate, POE 20 sorbitan monooleate, POE 40 sorbitol hexatalate;
- POE 40 sorbitol tetraoleate;
- POE 20 sorbitol trioleate;
- and mixtures of N,N′-bisoctanoylethylenediamine, N,N′-bisdecanoyl-ethylenediamine, N,N′-bisdodecanoylethylenediamine and N,N′-bistetradecanoylethylene-diamine.
