Abstract
A fiberboard comprising dried plant fibers added with binder resins obtained from a reaction between a diisocyanate and a polyol derived from natural oils or fatty acids, and formed by pressing at a temperature range of 50° C. to 150° C.
Claims17
A fiberboard, comprising:
- dried plant fibers derived from agricultural wastes;
- and
- binder resins of polyurethane oligomers obtained from a reaction between a diisocyanate and a polyol derived solely from natural oils;
- wherein the fiberboard is formed by pressing in a mold at a temperature range of 50° C. to 120° C.;
- wherein the diisocyanate content is less than 25% by weight of the polyurethane oligomers.
2 more elements
A fiberboard, comprising:
- dried plant fibers derived from palm wastes;
- and
- binder resins of polyurethane oligomers obtained from a reaction between a diisocyanate and a polyol derived solely from natural oils;
- wherein the diisocyanate is selected from the group consisting of methyl diphenyl diisocyanate (MDI), toluene diisocyanate (TDI), hexamethylene diisocyanate (HDI), isophorone diisocyanate (IPDI) and combinations thereof;
- wherein the natural oils are selected from the group consisting of palm oil, coconut oil, soy oil, jatropa oil, linseed oil, castor oil, rapeseed oil, tallow oil, fish oil and combinations thereof;
- wherein the fiberboard is formed by pressing in a mold at a temperature range of 50° C. to 100° C.;
- wherein the diisocyanate content is about 15% to less than 25% by weight of the polyurethane oligomers.
4 more elements
A method for manufacturing a fibreboard comprising:
- mixing dried plant fibers derived from agricultural wastes with binder resins of polyurethane oligomers obtained from a reaction between a diisocyanate and a polyol derived solely from natural oils;
- and
- pressing the mixture at a temperature range of 50° C. to 120° C. to form the fibreboard;
- wherein the diisocyanate content is less than 25% by weight of the polyurethane oligomers.
