阅读说明：本技术 制造聚氨酯泡沫鞋垫的方法 (Method for producing polyurethane foam shoe pad ) 是由 梁振鹏 钟运邦 于 2018-12-04 设计创作，主要内容包括：本发明涉及一种制造PU泡沫鞋垫的方法,其包括以下步骤：(1)将用于形成PU泡沫的原料浇注至模具中,使其反应以获得PU片材,其中模腔的高度为两个成品鞋垫总厚度的约1.0-约1.6倍,优选约1.1-约1.4倍,更优选约1.1-约1.3倍,最优选约1.1-约1.2倍；(2)将PU片材在水平方向上剖成两半以获得两片PU鞋垫材料,其中该材料的一个表面具有开孔,且该材料的另一个表面具有皮层；(3)将织物片附着至步骤(2)中所获得的材料的具有开孔的表面上。通过本发明制造的PU泡沫鞋垫具有低密度和良好回弹性、明亮且有光泽的皮层外观和良好透气性,且制造期间的原料利用率高。本发明克服了模内浇铸鞋垫的缺点如高密度和不良透气性,且可在鞋垫制造期间改善环境保护且满足消费者日益增加的需求。(The invention relates to a method for manufacturing PU foam insoles, which comprises the following steps: (1) pouring the raw materials for forming the PU foam into a mold and allowing them to react to obtain a PU sheet, wherein the height of the mold cavity is about 1.0 to about 1.6 times, preferably about 1.1 to about 1.4 times, more preferably about 1.1 to about 1.3 times, most preferably about 1.1 to about 1.2 times the total thickness of the two finished footbeds; (2) cutting the PU sheet into two halves in the horizontal direction to obtain two pieces of PU insole materials, wherein one surface of the materials is provided with openings, and the other surface of the materials is provided with a skin layer; (3) attaching a piece of fabric to the surface of the material obtained in step (2) having the openings. The PU foam insole manufactured by the invention has low density and good rebound resilience, bright and glossy skin appearance and good air permeability, and the raw material utilization rate during the manufacturing process is high. The present invention overcomes the disadvantages of in-mold cast insoles such as high density and poor air permeability and can improve environmental protection during insole manufacture and meet the increasing demands of consumers.)
