Abstract:
(EN) The present invention relates to a preparation method for a thermoplastic polyurethane micro airbag elastomer material, comprising the following steps: (1) feeding liquid raw materials such as diisocyanate molecules and a solid additive into a twin screw reactor, and carrying out a polymerization chain-extending reaction to obtain a hot melt having a high molecular weight; (2) pushing the hot melt having a high molecular weight into a mixing extrusion molding machine, and carrying out a reaction continuously to produce a macromolecular thermoplastic polyurethane melt; (3) continuously adding the obtained macromolecular thermoplastic polyurethane melt, polymer particles and the like into a foaming extrusion molding machine, and then extruding the material from a mold head to an underwater pelletizing chamber in the form of a high-pressure hot melt; (4) carrying the pellets by processing water through a multi-stage pressure relief and expansion processing water pipeline, delivering the pellets by the processing water to a separation machine, and carrying out separation, screening and drying to form a target product. Compared to existing technology, using the present invention allows for the preparation of the thermoplastic polyurethane elastomer material directly from liquid raw materials such as methylene diphenyl diisocyanate (MDI), so that energy consumption and material consumption are greatly lowered, the yield of a product is increased, and the production efficiency of the product is increased.
(FR) La présente invention concerne un procédé de préparation d’un matériau élastomère de micro-coussin d'air en polyuréthane thermoplastique, comprenant les étapes suivantes : (1) l'introduction de matières premières liquides telles que des molécules de diisocyanate et d'un additif solide dans un réacteur double vis, et la réalisation d’une réaction d’extension de chaîne de polymérisation pour obtenir une masse fondue à la masse moléculaire élevée ; (2) la pénétration de la masse fondue à la masse moléculaire élevé dans une machine de moulage par extrusion-mélange, et la réalisation d’une réaction en continu pour produire une masse de polyuréthane thermoplastique macromoléculaire ; (3) l'ajout en continu de la masse de polyuréthane thermoplastique macromoléculaire obtenue, des particules polymères et similaires dans une machine de moulage par extrusion-moussage, puis l'extrusion du matériau d’une tête de moule vers une chambre de pastillage immergée sous la forme d’une masse fondue à haute pression ; (4) le transport des pastilles dans de l'eau de traitement à travers une canalisation d'eau de traitement à décompression et à dilatation de pression à étages multiples, la distribution des pastilles par l’eau de traitement dans une machine de séparation, et la réalisation de la séparation, du criblage et du séchage pour former un produit cible. Par comparaison avec la technologie existante, l’utilisation de la présente invention permet la préparation d’un matériau élastomère de polyuréthane thermoplastique directement à partir de matières premières liquides telles que le diisocyanate de méthylène diphényle (MDI), de sorte que la consommation d’énergie et la consommation de matière sont grandement réduites, le rendement d’un produit est accru, et l’efficacité de production du produit est accrue.
(ZH) 本发明涉及一种热塑性聚氨酯微气囊弹性体材料的制备方法,包括以下步骤:(1)将二异氰酸酯类分子等液体原料与固体添加剂喂入双螺杆反应器,进行聚合扩链反应,得到高分子量的热熔体;(2)将高分子量的热熔体推入混炼挤塑机中,继续反应,生成高分子热塑性聚氨酯熔体;(3)继续将所得高分子热塑性聚氨酯熔体与聚合物颗粒等加入发泡挤塑机中,再以高压热熔体的形式从模头挤出至水下切粒室;(4)切粒由工艺水携带经多级释压膨胀工艺水管线送至分离机处,分离、筛选燥后,即形成目的产品。与现有技术相比,本发明可以直接从MDI等液体原料制成热塑性聚氨酯弹性体材料,极大的降低了能耗和物耗,提高了产品收率和生产效率等。
