Abstract
Decking comprises: a support selected from the group consisting of: polymeric materials; marine engineering polymers, fiber reinforced polymers, polymer metal composites, metal or wood sheets or marine superstructure; an array of strips of polymer treated wood secured to the support by means of an adhesive; the adhesive being selected from the group consisting of: polyurethane adhesives, modified silyl polymer adhesives and epoxy resin adhesives; wherein the polymer treated wood comprises a wood species selected from the group consisting of: maple species impregnated with a wood compatible polymerizable monomer, preferably selected from furfuryl alcohol, bis hydroxymethyl furan and mixtures thereof and subsequently dried and cured.
Claims20
Marine decking comprising:
- a support selected from the group consisting of polymeric materials;
- marine engineering polymers, fibre reinforced polymers, polymer metal composites, metal or wood sheets or marine superstructure;
- and
- an array of strips of polymer treated wood secured to the support by an adhesive, the array of strips forming an upper surface opposite the support,
- wherein the polymer treated wood includes a maple species impregnated with a polymer selected from the group consisting of furfuryl alcohol, bis hydroxymethyl furan, and mixtures thereof, and
- wherein the strips of polymer treated wood are oriented such that annual rings of at least some of the strips form a non-vertical angle with the upper surface.
A process for manufacture of a marine decking, the process comprising the steps of
- impregnating wooden strips including a maple species with a polymerizable composition comprising:
- (i) a polymer selected from the group consisting of furfuryl alcohol, bishydroxymethyl furan, and mixtures thereof;
- (ii) a catalyst;
- (iii) a solvent selected from the group consisting of water, C1-C4 alcohols, and mixtures thereof;
- and
- (iv) optionally one or more stabilisers or other ingredients;
- to produce impregnated decking strips;
- following impregnation, subjecting the impregnated decking strips to a water removal process comprising maintaining the impregnated decking strips in an atmosphere having a pressure of 10 kPa (0.1) to 50 kPa (0.5 bar), at a first temperature of 50 to 90° C., for a duration sufficient to cause removal of water from the impregnated decking strips;
- and
- following the water removal process, maintaining the impregnated decking strips at a second temperature higher than the first temperature to cure the polymerizable composition and form polymer treated decking strips.
A process for the manufacture of a marine decking, the process comprising the steps of:
- impregnating wooden strips including a maple species with a polymerizable composition, the polymerizable composition including:
- a polymer selected from the group consisting of furfuryl alcohol, bishydroxymethyl furan, and mixtures thereof;
- a catalyst selected from the group consisting of maleic acid, malic acid, phthalic acid, benzoic acid, citric acid, organic anhydride, aluminum chloride, ammonium salt, and combinations thereof;
- and
- a solvent selected from the group consisting of water, C1-C4 alcohols, and mixtures thereof;
- to produce impregnated decking strips;
- following impregnation, drying the impregnated decking strips at a first temperature for a duration sufficient to cause removal of water from the impregnated decking strips;
- and
- following the drying process, curing the polymerizable composition by heating the impregnated decking strips to a second temperature higher than the first temperature to form polymer treated decking strips.
