The present invention relates to a foaming composition of soft polyurethane used for the cushion insert for vehicles and more specifically, to a foaming composition of soft polyurethane which comprises polymerpolyol wherein solid polymer synthesized from acrylonitrile or styrene monomer is grafted or dispersed in polyetherpolyol, polyol wherein polyetherpolyol is mixed, crosslinkage agent, amine catalysts, foaming agent and organic silicon defoaming agent, and which provides greatly improved productivity and reduced inferiority owing to the natural crushing of independent foam cells through chemical method rather than physical method.
本发明涉及一种用于汽车坐垫内衬的软质聚
氨酯发泡组合物,更具体地说,涉及一种软质聚
氨酯发泡组合物,该组合物由聚合物多元醇组成,其中由
丙烯腈或
苯乙烯单体合成的固体聚合物接枝或分散在聚醚多元醇中、 混合了聚醚多元醇的多元醇、
交联剂、胺催化剂、发泡剂和有机
硅消泡剂,通过
化学方法而不是物理方法,大大提高了生产率,并减少了由于独立泡沫单元的自然破碎而产生的劣质产品。
