    • An extruded styrene resin foam which is made with a foaming agent imposing a reduced load on the environment and has exceedingly high heat-insulating performance and flame retardancy which makes the foam suitable for use in building applications. The foam, which is obtained by extrusion-foaming a styrene resin, is characterized in that the foaming agent used comprises at least one C3-5 saturated hydrocarbon and that the foam contains a halogenated flame retardant (A) and at least one compound (B) selected from the group consisting of phosphorus compound flame retardants containing a nitrogen atom in the molecule, tetrazole compounds, specific nitrogenous compounds, metal borates, and boron oxide and has a cell structure in which the degree of cell anisotropy, k, represented by the equation k=a/(axbxc) (wherein a (mm) represents the average cell diameter in the thickness direction in a section of the foam, b (mm) represents the average cell diameter in the width direction, and c (mm) represents the average cell diameter in the length direction) is k
    • 一种挤出的苯乙烯树脂泡沫,其由发泡剂制成,在环境上施加减轻的负荷并且具有极高的绝热性能和阻燃性,这使得泡沫适合用于建筑应用。 通过挤出发泡苯乙烯树脂获得的泡沫的特征在于所用的发泡剂包含至少一种C3-5饱和烃,泡沫中含​​有卤化阻燃剂(A)和至少一种化合物(B )选自由分子中含有氮原子的磷化合物阻燃剂组成的组,四唑化合物,特定含氮化合物,金属硼酸盐和氧化硼,并且具有以下结构:细胞各向异性k 方程式k = a /(axbxc)<1/3>(其中a(mm)表示泡沫的截面中的厚度方向上的平均泡孔直径,b(mm)表示宽度方向的平均泡孔直径, c(mm)表示长度方向上的平均气泡直径)为k

    • An improved process for making a structural foamed polymer, a multilayer polymer film, sheet or tube, a pultrusion polymer profile, a compression molded extruded fiber reinforced polymer pre-form, a strand foamed polymer and a SCORIM formed polymer article. The improvement includes the step of dispersing a multi-layered silicate material with the polymer so that the polymer has dispersed therein single layers of silicate material, double layers of silicate material, triple layers of silicate material, four layers of silicate material, five layers of silicate material and more than five layers of silicate material, the volume percent of the one, two, three, four and five layers of silicate material greater than the volume percent of the more then five layers of silicate material. In each of the above embodiments an important benefit of the instant invention is the orientation of the plane of the layers of silicate material. Preferably, most of the layers of silicate material have substantially the same orientation within thirty degrees of angle. Such orientation improves the properties of the product and provides a practical way to make larger products. The amount of multi-layered silicate material used is preferably between one and twenty percent.
    • 制造结构发泡聚合物,多层聚合物膜,片或管,拉挤聚合物轮廓,压缩模制的挤出纤维增强聚合物预成型剂,线股发泡聚合物和SCORIM形成的聚合物制品的改进方法。 改进之处在于分散多层硅酸盐材料与聚合物的步骤,使得聚合物分散在其中单层硅酸盐材料,双层硅酸盐材料,三层硅酸盐材料,四层硅酸盐材料,五层 硅酸盐材料和五层以上的硅酸盐材料,一层,二层,三层,四层和五层硅酸盐材料的体积百分比大于五层以上硅酸盐材料的体积百分比。 在每个上述实施例中,本发明的重要益处是硅酸盐材料层的平面的取向。 优选地,大多数硅酸盐材料层在30度角内具有基本相同的取向。 这种取向改善了产品的性能,并提供了制作更大产品的实用方法。 多层硅酸盐材料的使用量优选在百分之一到百分之二十之间。
