LAMINATES

摘要

A method of manufacturing a laminate comprises - providing a binder impregnated core layer by impregnating at least one fibrous layer with an aqueous core binder solution having a viscocity in the range 75 cP to 500 cP at a temperature of 20°C and a bake-out solid content in the range 40 wt% to 85 wt%, in which the aqueous core binder solution comprises (i) at least 25% by dry weight of a) reducing sugar reactant(s) and nitrogen-containing reactant(s) and/or b) curable reaction product(s) of reducing sugar reactant(s) and nitrogen-containing reactant(s); and (ii) between 5% and 15% by weight of a non-aqueous solvent based on the total weight of the aqueous binder solution; - providing a semi-finished assembly by assembling the binder impregnated core layer with a surface layer; and - applying heat and pressure to the semi-finished assembly to cure the binder in the binder impregnated core layer and secure the core layer and the surface layer together.
