Abstract:
(EN) The present invention relates to a micro-particle-size thermoplastic micro-airbag polyurethane elastomer material and preparation therefor, the material formula comprising the following ingredients in percentage by weight: 1%-97% of a support skeleton polymer material, 1%-97% of a pressure-proof slow-springback polymer material, 0.01%-0.5% of a nucleating agent and 0.1%-10% of a foaming agent. The material is prepared by means of the following method: (1) feeding the polyurethane raw material and the nucleating agent from a feeding opening in the front end of a twin-screw extruder, feeding the foaming agent from a feeding opening in a middle section, carrying out hot melting on the raw materials, adequately mixing, putting the raw materials into a static mixer, carrying out further homogenization, and carrying out pressure control and quantitative conveying by means of a melt pump; and (2) introducing a hot melt sent out by the melt pump into an underwater particle dicing chamber by means of a mold head, carrying out particle dicing, bringing out particles using processing water for separation, and sieving and drying the obtained particles so as to obtain a target product. Compared to existing technology, the product of the present invention has a winding network air way interpenetration structure formed by an apropriate micro-airbag structure and a suitable opening foam hole, and the particle sizes may be effectively controlled to be at about 0.5mm-2mm.
(FR) La présente invention concerne un matériau élastomère de polyuréthane de micro-airbag thermoplastique de taille microparticulaire et sa préparation, la formule du matériau comprenant les ingrédients suivants en pourcentage en poids : de 1 % à 97 % d'un matériau polymère à squelette de support, de 1 % à 97 % d'un matériau polymère de retour à élasticité lente et résistant à la pression, de 0,01 % à 0,5 % d'un agent de nucléation et de 0,1 % à 10 % d'un agent moussant. Le matériau est préparé au moyen du procédé suivant : (1) alimenter la matière première de polyuréthane et l'agent de nucléation à partir d'une ouverture d'alimentation dans l'extrémité avant d'une extrudeuse à double vis, alimenter l'agent moussant à partir d'une ouverture d'alimentation dans une section centrale, mettre en œuvre une fusion à chaud sur les matières premières, mélanger de manière adéquate, placer les matières premières dans un mélangeur statique, réaliser une homogénéisation supplémentaire, et réaliser une régulation de pression et un transport quantitatif au moyen d'une pompe à masse fondue; et (2) introduire une masse fondue chaude envoyée par la pompe à masse fondue dans une chambre de découpage en dés de particules sous-marine au moyen d'une tête de moule, réaliser un découpage en dés de particules, isoler des particules à l'aide d'eau de traitement pour la séparation, puis tamiser et sécher les particules obtenues de façon à obtenir un produit cible. Par rapport à la technologie existante, le produit selon la présente invention a une structure d'interpénétration d'air de réseau d'enroulement formée par une structure de micro-airbag appropriée et un trou de mousse d'ouverture approprié, et les tailles de particules peuvent être efficacement contrôlées pour être d'environ 0,5 mm à 2 mm.
(ZH) 本发明涉及一种微粒径热塑性微气囊聚氨酯弹性体材料及其制备,材料配方包括以下重量百分比含量的组分:支撑骨架聚合物材料1-97%,耐压慢回弹聚合物材料1-97%,成核剂0.01~0.5%,发泡剂0.1~10%;其通过以下方法制成:(1)将聚合物原料和成核剂从双螺杆挤塑机前端加料口喂入,发泡剂从中段加料口喂入,使各原料热熔混合充分后,再进入静态混合器进一步均质化,接着再经熔体泵控压和定量输送;(2)被熔体泵送出的热熔体通过模头进入水下切粒室切粒,并由工艺水带出分离,所得颗粒筛选干燥后即得到目的产品。与现有技术相比,本发明的产品具有合适的微气囊结构和适度的开口泡孔形成的缠绕网络气道互穿结构,颗粒粒径可有效控制在0.5-2mm左右等。
