A method for manufacturing foam pads includes a first step of preparing a
proper amount of PVC power, DOP curing agent, light calcium carbonate,
kaolin, foaming agent and pigment and pouring them into a blending device
to be blended and form a liquid starchy material. Next, the liquid
starchy material is conveyed into an intermediate material barrel and
kept stationary for pre-foaming at normal temperature for about 8 hours
and then coated on a conveyer pelt to form a starchy material layer.
Subsequently, the starchy material layer is kept stationary and heated at
80-90.degree. C. for about 3-10 minutes and then continuously heated at
185-200.degree. C. for about 20-30 minutes to form an integral-sheeted
foam pad. After cooled, the integral-sheeted foam pad is
thermo-compressed and cut into various foam pad products.
