US Classification:

156296, 156 622, 1563314, 1563317, 264109
Abstract:

A method for preparing compression molded or pressed lignocellulosic articles is disclosed. The method involves forming a binder resin by combining a polyisocyanate component with a parting agent and preferably a synergist. The parting agent is the reaction product of an isocyanate compound and an isocyanate-reactive compound of the general structure Râ(ao) âY where: R is a hydrophobic group containing alkyl, alkaryl, polyaryl, or siloxane moieties; (ao) is an alkylene oxide or mixture of alkylene oxides; n is from 1 to 25; and Y represents a monofunctional isocyanate-reactive group. A resinated lignocellulosic mixture is formed by combining the binder resin with lignocellulosic particles. Then a compression molded or pressed lignocellulosic article is formed by compressing the resinated lignocellulosic mixture at an elevated temperature and under pressure. It is particularly preferred that the binder resin further include a synergist of either a C N-alkylpyrrolidone, gamma-butyrolactone, or a mixtures of them.

US Patent:

7416785, Aug 26, 2008
Filed:

May 26, 2004
Appl. No.:

10/853826
Inventors:

Donald C. Mente - Grosse Ile MI, US
Assignee:

BASF Corporation - Florham Park NJ
International Classification:

B32B 5/16
C05F 11/00
US Classification:

428407, 71 6407, 71 6411, 524722
Abstract:

An encapsulated particle includes a core particle. The core particle includes a fertilizer selected from the group of nitrogen, phosphate, potash, and sulfur, and combinations thereof. The core particle may also include herbicides, insecticides, and fungicides. The encapsulated particle also includes a polyurethane layer disposed about the core particle. The polyurethane layer includes the reaction product of an aromatic isocyanate component and a polyol that is reactive with the aromatic isocyanate component. The aromatic isocyanate component includes methylene diphenyl diisocyanate, toluene diisocyanate, and mixtures thereof. The polyol that is reactive with the aromatic isocyanate component is derived from an aromatic amine-based initiator and includes a toluene diamine. The aromaticity of the aromatic isocyanate component and the polyol serves to insure complete miscibility between the aromatic isocyanate and the polyol thereby forming the polyurethane layer without defects preventing water from permeating the polyurethane layer and dissolving the core particle.

Assignee:

BASF Corporation - Florham Park NJ
International Classification:

C08L 97/02
US Classification:

523122, 524 14
Abstract:

A lignocellulosic composite material and a method for preparing the lignocellulosic composite material are disclosed. The composite material is formed from lignocellulosic particles and a binder resin. The binder resin comprises a polyisocyanate, at least one of insecticide and/or fungicide that are dispersed throughout the polyisocyanate. The insecticide and/or fungicide is also dispersed throughout the lignocellulosic particles. Since the insecticide and/or fungicide is dispersed throughout the composite material, the composite material is insect resistant and is able to withstand insect attacks and prevent fungus growth and decay.

US Classification:

71 1, 71 6407, 71 6411, 428407
Abstract:

An encapsulated particle comprises a core particle and a polyurethane layer disposed about the core particle. The core particle can be various particles, such as fertilizer, biocides, flame retardants, seeds, etc. The polyurethane layer comprises the reaction product of an isocyanate component and an isocyanate-reactive component. The isocyanate-reactive component comprises a graft polyol having a continuous phase and polymeric particles. A method of forming the encapsulated particle comprises the steps of providing the core particle, applying the isocyanate and isocyanate-reactive components to the core particle, and reacting the isocyanate and isocyanate-reactive components to form the polyurethane layer. The encapsulated particle has excellent physical properties, such as increased water repellency, resiliency and shelf life.
