Environment-friendly thermal-insulation core material and preparation method thereof
The invention relates to an environment-friendly thermal-insulation core material, which is composed of the following components in percentage by mass: 35-55% of kaolin; 15%-25% of organic microspheres; 5%-10% of scrap iron minerals; 5%-8% of waste glass powder; 5%-10% of bentonite; 2%-5% of talcum powder; and 2%-5% of a surfactant. According to the invention, the organic microspheres are used asa porous template in the thermal insulation core material; the organic microspheres are prepared into microspheres by adopting a spherical granulator and then are sieved; the prepared microspheres areuniform in size, organic microspheres can still not be scattered or powdered to form uniform microspheres of a porous structure after being calcined at high temperature by adopting a coke adhesive, the porous microspheres uniform in size are uniformly distributed in the heat preservation core material so that uniform pore distribution is obtained, the preparation process is controllable, the mechanical property is good, and the heat preservation effect is good.
一种环保保温芯材，由下列按照质量百分数计的组分组成：高岭土35%—55%；有机微球15%—25%；废铁矿物5%—10%；废玻璃粉5%—8%；膨润土5%—10%；滑石粉2%—5%；表面活性剂2%—5%。本发明采用有机微球作为保温芯材内的多孔模板，有机微球采用球形造粒机制备成微球再过筛，出来的微球尺寸均匀，又采用了焦炭粘接剂使有机微球经过高温煅烧后仍可不散不粉形成多孔结构的均匀微球，大小均匀的多孔微球在保温芯材中均匀分布，使其获得均匀的孔隙分布，制备工艺可控，力学性能好，保温效果好。
