Abstract
The invention relates to a method for making a ground coating made of a thermoplastic material, that comprises the steps of (a) depositing a layer of a liquid component on a substrate, the liquid component being selected from a plastisol, an organosol or an SBR rubber emulsion, (b) powdering solid particles on the liquid component layer, and (c) applying press heat in order to form a ground coating having a smooth surface. The invention also relates to a device for obtaining such coatings.
Claims5
A process for manufacturing a thermoplastic floor covering comprising the following steps:
- (a) depositing a layer of a liquid component onto a support, the liquid component comprising a plastisol, an organosol or an emulsion of SBR rubber;
- (b) sprinkling solid particles onto the layer of liquid component;
- and
- (c) applying pressure and heat between a lower conveyor belt and an upper conveyor belt to form a floor covering that has a smooth surface, the pressure being limited to between 0.1 and 5 bar;
- and
- (d) a pregelling step between the step (b) of sprinkling particles onto the layer of liquid component and the step (c) of applying pressure and heat.
