Abstract
A method of making a composite product, such as a basin or a tile, includes the steps of impregnating particles of an exfoliated vermiculite or a lignocellulosic material with an impregnating composition comprising a first thermosetting resin, an extending liquid for the thermosetting resin, if necessary a catalyst for the thermosetting resin and a colouring agent for the particles; removing the extending liquid; subjecting the impregnated particles to suitable conditions, generally of temperature and for pressure, to polymerise or cross-link the first thermosetting resin; coating the particles so produced with a binder composition comprising a second thermosetting resin and if necessary a catalyst for the second thermosetting resin; forming the particles into a desired shape, either in a mould or on a plate of a press; and subjecting the particles to suitable conditions to polymerise, condense or cross-link the second thermosetting resin to bind the particles together to form the composite product.
Claims
AMENDED CLAIMS
[received by the International Bureau on 23 December 1997 (23.12.97); original claims 1-18 replaced by amended claims 1-15 (4 pages)]
A method of making a composite product includes the steps of:
(1) impregnating particles o f an exfoliated vermiculite ■ with an impregnating composition comprising a first thermosetting resin, an extending liquid for the first thermosetting resin, if necessary a catalyst for the first thermosetting resin, and a colouring agent for the particles;
(2) removing the extending liquid;
(3) subjecting the impregnated particles to suitable conditions to polymerise or cross-link the first thermosetting resin;
(4) coating the particles of step (3) with a binder composition comprising a second thermosetting resin and if necessary a catalyst for the second thermosetting resin;
(5) forming the particles of step (4) into a desired shape; and
(6) subjecting the particles of step (5) to suitable conditions to polymerise or cross-link the second thermosetting resin to bind the particles together to form the composite product.
A method according to claim 1 wherein the colouring agent is selected from the group consisting of a pigment dispersed in the impregnating composition, and a dye dissolved in d e impregnating composition.
A method according to claim 1 or claim 2 wherein in step ( 1 ) the particles are impregnated with the impregnating composition by
immersion in the impregnating composition, by mixing with the impregnating composition, or by spraying the impregnating composition onto the particles
A method according to any one of claims 1 to 3 wherem in step (2) the extending liquid is recovered for reuse
A method according to any one of claims 1 to *> wherein in step (3) the impregnated particles are subjected to any one or more of elevated temperature, irradiation, exposure to ultra violet light, and elevated pressure
A method accordmg to any one of claims 1 to 5 wherem m step (4) the particles of step (3) are coated with the binder composition by mixing
A method according to any one of claims 1 to 6 wherein the first thermosetting resin and the second thermosetting resin are the same
A method according to any one of claims 1 to 7 wherein m steps (5) and (6) the particles of step (4) are placed in a mould and subjected to suitable conditions to polymerise or cross-link the second thermosetting resin to bind the particles together to form the composite product in the mould
A method according to any one claims 1 tc 7 wherein in steps (5) and (6) the particles of step (4) are placed on a substrate to which the particles are to be adhered and then subjected to suitable conditions ol elevated temperature and pressure to polymerise or cross-link the
second thermosetting resm to adhere the particles to the substrate and to bind the particles together to form the composite product
I o A method accordmg to any one of claims 1 to 7 wherem m steps (5) and (6) the particles of step (4) are placed on a plate of a suitable press and then subjected to suitable conditions of elevated temperature and pressure to polymerise or cross-link the second thermosetting resm to bmd the particles together to form the composite product
I I A method accordmg to any one of claims 1 to i o wherem the particles of an exfoliated vermiculite are impregnated with from 5 % to 60% by weight of me first thermosetting resm and then the treated particles are coated with from 5% to 300% by weight of the second thermosetting resm
12 A composite product comprises
(a) particles of an exfoliated vermiculite impregnated with a first thermosetting resin and a colouring agent for the particles, the first thermosetting resm having been polymerised or cross-linked, and (b) a binder comprising a second thermosetting resm, the second thermosetting resin having been polymerised or cross -linked to
bind the particles together to form the composite product.
A composite product according to claim 12 made by a method according to any one of claims 1 to 1 1 .
A composite product according to claim 12 or claim 13 wherein the first thermosetting resin and the second thermosetting resin are selected from a group consisting of phenol formaldehyde resole resins, unsaturated polyester resins, melamine formaldehyde resins, melamine urea formaldehyde resins, acrylic or methacrylic resins, isocyanate resins and epoxy resins.
A composite product according to any one of claims 12 to 14 wherein the colouring agent is selected from a group consistmg of a pigment and a dye.
