| titleOfInvention | Method of preparation of low price of polyether polyurethane for elastic floor |
| abstract | The present invention relates to a method for producing a polyether polyurethane. More specifically, the method for producing a polyether polyurethane of the present invention is a paste prepared by mixing 8 to 20% by weight of a prepolymer, 5 to 16% by weight of chain extender, 60 to 85% by weight of bicarbonate, and 2 to 4% by weight of a pigment. obtaining a mixed composition of paste; The paste-like mixed composition is prepared in the form of a plate through a single-stage roller and a two-stage flat roller provided with uneven parts, and is continuously transferred to a three-stage roller provided with uneven parts, thereby hardening a stranded polyether polyurethane. Obtaining a material; And cutting the strand-type polyether polyurethane material through a cutter equipped with a blade. The preparation method of the present invention simplifies the process by preparing a prepolymer using a compound having at least one low molecular weight hydroxy selected from C 1 to C 5 straight or pulverized alcohols or heteropolyols, The reaction time can be shortened and the fine dust generation process can be omitted, thereby providing a low cost polyether polyurethane, and replacing the conventional polyester polyurethane and a series of polyurethane chips including the same. |
