Abstract
Official abstract text for this publication.
A composition for an automotive interior skin, a method for manufacturing the same, and an automotive interior skin manufactured using the same. The composition for an automotive interior skin includes: 30 wt % to 70 wt % of a polyol compound; 5 wt % to 40 wt % of dicyclohexylmethane-4,4′-diisocyanate; and 5 wt % to 30 wt % of an aromatic glycol-based chain extender.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for manufacturing a composition for an automotive interior skin, comprising the steps of: producing an intermediate molded body by kneading the composition for an automotive interior skin, comprising: 30 wt % to 70 wt % of a polyol component; 5 wt % to 40 wt % of dicyclohexylmethane-4,4′diisocyanate; and 5 wt % to 30 wt % of an aromatic glycol-based chain extender; producing a Pulverized Material by drying and Pulverizing the intermediate molded body at −60° C. or below; subjecting the Pulverized Material to first stirring at 80° C. or above; and subjecting the stirred Pulverized Material to second stirring. 2. The method of claim 1 , wherein the intermediate molded body is dried at a temperature of −60° C. to −190° C. 3. The method of claim 1 , wherein, after the step of producing the Pulverized Material, 0.05 parts by weight to 5 parts by weight of a drying agent is added to 100 parts by weight of the Pulverized Material, and the first stirring is performed. 4. The method of claim 1 , wherein the first stirring is performed by stirring the Pulverized Material at 500 rpm to 1,500 rpm and at 80° C. to 110° C., and the second stirring is performed by stirring the stirred Pulverized Material at 200 rpm to 1,000 rpm.
