A scald-resistant synthetic leather includes a silicone layer and a high-temperature resistant substrate disposed in sequence from top to bottom. A preparing method includes coating and vulcanizating a silicone slurry on the high-temperature resistant substrate, after coating the silicone slurry, sending the high-temperature resistant substrate and the silicone slurry to a drying tunnel for vulcanization to allow attachment of the silicone layer and the high-temperature resistant substrate; after the vulcanization, peeling the silicone layer and the high-temperature resistant substrate apart to obtain the scald-resistant synthetic leather; the number of processes of coating and vulcanizating is more than one, and a thickness for a single coating is 0.02-3 mm; a total thickness for coating is 0.2-0.5 mm. The silicone slurry and the high-temperature resistant substrate used in the disclosure both are environmentally friendly and harmless materials. The high-temperature resistant substrate provides a fundamental framework, and the silicone slurry is the cover.

A foamed, opacifying element having a target light blocking value (LBV.sub.T) and a target porous substrate is prepared by determining the light blocking value (LBV.sub.S) of the target porous substrate; calculating the LBV.sub.T-S difference; choosing a foamable aqueous composition; determining a dry coating weight for the chosen foamable aqueous composition (when foamed); and using the dry coating weight to form the single dry opacifying layer as the only layer disposed on the target porous substrate, such that the single dry opacifying layer has light blocking value that is equal to LBV.sub.T-S, 10%. The chosen foamable aqueous composition comprises the essential components (a) through (e) described herein. The desired foamable aqueous composition can be chosen from a set of similar compositions to achieve the desired LBV.sub.T with the noted target porous substrate using suitable mathematical formula relating dry coating weight to light blocking value and a suitable data processor.
