轻质填料种类对固体浮力材料性能的影响

Effect of Lightweight Filler Types on Performance of Solid Buoyancy Materials

以环氧树脂、复合固化剂与轻质填料为主要原料制备固体浮力材料。研究了轻质填料种类对材料密度、抗压强度、吸水性和冲击断面微观形貌的影响。结果表明:综合考虑不同种类轻质填料对材料密度和抗压强度的影响,可膨胀微球发泡剂WS606的综合性能良好,复合轻质填料中少量WS606的掺杂有利于减少空心玻璃微珠(HGB)加入量,且对样品性能无明显负面影响;AC发泡剂CCR-20对材料抗压强度的负面影响较大,但对材料密度的降低作用明显;以10%HGB-S15+3%WS606作为复合轻质填料制得的样品具有相对较低的密度和相对较高的抗压强度,分别为0.42g·cm^(-3)和14.06 MPa。

The solid buoyancy materials were prepared by using epoxy resin, compounded curing agent and lightweight filler as the main raw materials. The effect of lightweight filler type on density, compressive strength, water absorption capacity and micro-morphology of the impact fracture surface of the materials was investigated. The results showed that the comprehensive properties of expandable microsphere foaming agent-WS606 were better by comprehensive consideration from the effect of different types of lightweight filler on density and compressive strength of the materials. A small amount of WS606 doped into composite lightweight filler was beneficial to reduce the adding amount of hollow micro-glass ball(HGB) and had no obvious negative effect on material properties. AC foaming agent-CCR-20 had obvious negative effect on compressive strength of the materials, but had obvious positive effect on decreasing density of the materials. With 10%HGB-S15+3%WS606 as a composite lightweight filler, the prepared materials had relatively lower density and relatively higher compressive strength,being 0.42 g·cm^(-3) and 14.06 MPa respectively.
