Laminated board
First Claim
1. An insulating board laminate panel structure having a combination of a fiber reinforced water-hardened cement mortar layer securely bonded to an insulating foam material so that high bond strength between said insulating board and said cement mortar layer is achieved and said resulting laminate panel has higher buckling strength, load bearing and impact resistance, wherein said panel structure is composed of:
- (A) said insulating board foam material having a density of less than about 0.5 grams/cc; and
(B) said water-hardened cement mortar layer adjacent said insulating board material has a composition consisting essentially of;
(i) cement mortar having a weight ratio of water to said cement mortar between 0.2 to 0.5, and further having up to 40 percent by volume of reinforcing fibers; and
(ii) a dispersion of an addition-polymerized resin of vinyl monomers having an average particle size of between 0.05 to 1.5 microns, said resin being present in a resin to said cement weight ratio of between 0.02 to 0.4 and containing between 2.5% to 30.0% by weight of monomers having an acid group.

Abstract
Laminated board structures having excellent mechanical properties made up of a layer of thermal and/or acoustic insulating material strongly bonded to a layer of fibre-reinforced water hardened cement with an aqueous dispersion containing an addition polymer preferably containing acid groups and having an average particle size between 0.05 micron and 5 microns. Improved mortar composition used in the laminate structure.
