Abstract

The invention provides a preparation method of a wear-resistant heat-insulation polystyrene material. The method comprises the following steps: (1) preparing carbon spheres from sucrose by a hydrothermal process; (2) preparing a carbon sphere liquid from the carbon spheres, preparing an SDBS (sodium dodecyl benzene sulfonate) liquid from SDBS, and mixing to obtain a mixed liquid A; (3) mixing zirconium oxychloride, hexamethylenetetramine, urea and deionized water to obtain a mixed liquid B, and mixing TEOS (tetraethyl orthosilicate) and ethanol to obtain a mixed liquid C; (4) mixing the mixed liquids A, B and C, using the carbon spheres as the template, and calcining to remove the template, thereby obtaining composite hollow microspheres; (5) carrying out modification treatment on the composite hollow microspheres by using KH570 to obtain modified composite hollow microspheres; and (6) weighing the raw materials, mixing the raw materials, extruding, cooling, drying, and granulating to obtain the wear-resistant heat-insulation polystyrene material. The prepared polystyrene material has favorable heat-insulating property and wear resistance.

Description

technical field [0001] The invention relates to a polymer material, in particular to a preparation method of a wear-resistant and heat-insulating polystyrene material. Background technique [0002] Since the first industrial production of polystyrene in Germany in the early 1930s, its application fields have also been expanding. So far, polystyrene has achieved large-scale and leapfrog development. Polystyrene material has the characteristics of superior water and moisture resistance, light weight, high hardness, high impact resistance, and good thermal insulation performance. Now one of its most important application fields is used as building exterior wall insulation material - polystyrene Vinyl foam board. The existing polystyrene foam board achieves the thermal insulation effect by adding a foaming agent to the polystyrene to form fine closed cells after foaming. The disadvantage of this method is that the mechanical properties of the polystyrene material are reduced. I...
