Abstract
A composition for a car interior trim including: a polyurethane sponge layer for a car interior trim; and a water-soluble resin layer formed on the polyurethane sponge layer and comprising 20 to 50 parts by weight of a phosphorus-based flame retardant and 1 to 5 parts by weight of a thickener, based on 100 parts by weight of a coating agent blend of one or two more of a water-dispersed polyurethane or an aqueous acrylic resin.

A composition for a car interior trim comprising:
- a polyurethane sponge layer for a car interior trim;
- and
- a water-soluble resin layer formed on the polyurethane sponge layer and comprising 20 to 50 parts by weight of a phosphorus-based flame retardant and 1 to 5 parts by weight of a thickener, based on 100 parts by weight of a coating agent blend of one or two more of a water-dispersed polyurethane or an aqueous acrylic resin.
A method of preparing a composition for a car interior trim comprising:
- adding a phosphorus-based flame retardant into a resin and dispersing it, thereby preparing a coating agent (step 1);
- adding water into the dispersed coating agent and dispersing it at low speed, thereby preparing an aqueous resin (step 2);
- adding a thickener into the aqueous resin to control viscosity (step 3) rotating a polyurethane sponge layer on a roller and coating the aqueous resin thereon (step 4);
- and
- drying the polyurethane sponge layer coated with the aqueous resin (step 5).
