Definitions

• the present invention relates to a method for manufacturing floor or wall coverings based on plastisol, having improved resistance to soiling. It also relates to a floor or wall covering obtained by said process.
• the object of the present invention is to provide a method of manufacturing floor or wall coverings based on plastisol comprising a wear layer having improved resistance to soiling, in particular to soiling by the heels of shoes.
• Another object of the present invention is to provide a floor covering having a wear layer based on plastisol of a new type.
• An additional object of the present invention is to provide a floor covering having a plastisol-based wear layer having improved resistance to soiling, in particular to soiling due on the heels of shoes, even after repeated washing and / or cleaning.
• the method of manufacturing floor or wall covering based on plastisol, having improved resistance to soiling is characterized in that it is deposited on a decorative support, as a layer of wear, a mixture of plastisol containing a silicone polymer, a crosslinking agent and optionally a catalyst and in that the pregelling and gelling of the wear layer are carried out.
• the silicone polymer is incompatible with the plastisol of the wear layer.
• the crosslinking of the silicone polymer is carried out at the same time as the gelling of the plastisol of the wear layer.
• the silicone polymer is allowed to migrate to the surface by controlling the crosslinking thereof which is preferably carried out at the same time as the gelling of the plastisol, thanks to the appropriate choice of the catalyst / crosslinking agent couple and by the proper dosage of these.
• the silicone polymer used consists of a silicone gum carrying functional -OH groups.
• the crosslinking agent may consist of a silicone-based fluid with reactive -H groups. It may however also consist of an isocyanate which may be of the blocked type. When a blocked type isocyanate is used, the system and the release of -NCO- groups allowing the crosslinking of the silicone polymer to -OH groups is triggered at a relatively high temperature but below the maximum working temperature, for example 130 ° C.
• 0.1 to 10% of silicone polymer carrying OH groups and allowing crosslinking in the plastisol of the wear layer is between 10/10 and 10 / 0.1.
• the catalyst / silicone ratio can be between 0.1 and 0.001.
• a floor or wall covering characterized in that it comprises a decorative support obtained according to methods known per se, coated with a wear layer based on of plastisol containing a crosslinked silicone polymer.
• micronized polyethylene wax can be added to the plastisol mixture intended to form the wear layer.
• the crosslinked silicone polymer is found at a higher surface density than at the core of said wear layer.
• the silicone polymer used is a gum of the type Q 2 32 38 (trade name) from Dow Corning carrying functional -OH groups.
• the crosslinking agent is Dow Corning 1107 Fluid which contains silicone -H groups.
• non-crosslinked silicone gum (1) avoids immediate soiling but does not prevent the relatively heavy soiling after a few cleaning cycles. This is due to the fact that the silicone is not crosslinked and is in an emulsifiable system washable with cleaning water.
• Tests (2), (3) and (4) show that thanks to the use of a crosslinking agent for the silicone polymer, the resistance to soiling is notably improved, even after 100 cleaning cycles.
• test no. 4 Through the use of a catalytic system which adapts the crosslinking in order to allow surface migration of the silicone polymer incompatible with the plastisol in which it is mixed.
• a polyaliphatic polyisocyanate in solution containing about 8% free isocyanate was used as the crosslinking agent.
• this crosslinking agent Thanks to the use of this crosslinking agent, the ability of the product obtained to be stored is improved and the migration of the silicones on the surface is favored, since the release of the blocked NCO groups is only carried out from with a temperature of the order of 130 ° C.
• composition used is: - PVC 100 plastisol - silicone polymer (Q 2 32 38 Dow Corning) 1.25 - micronized polyethylene wax 2 - crosslinking agent: HÜLS IPDI B 1370 (trade name) 0.35 - tin catalyst (dibutyltin dilaurate) 0.001
• the plastisol mixture used can be stored for an extended period without undergoing crosslinking of the silicone system.
