在船舶行业中,由于船体内外存在温度梯度,导致在船体内壁易产生水的凝露问题。中空微球是一种特殊的薄壁、封闭的微球材料,球体内部包裹一定量的气体,具有隔热、低密度、环保等功效。通过对聚醋酸乙烯酯进行改性,以提高其耐水性等方面的性能,同时利用不同粒径中空微球在保温、强度等方面的性能差异,研制出一种可直接涂覆在船体内部的、具有自粘性的隔热材料。该隔热材料经过近几年的实际应用,能有效解决国内船舶业普遍存在的船体凝露问题,改善了船舱工作环境,具有较好的社会经济效益。
In the shipbuilding industry, due to the temperature gradient inside and outside the hull, condensation of water easily occurs on the inner hull wall. Hollow microspheres are a kind of special thin-walled and closed microspheres material. The spheres contain a certain amount of gas, which has the functions of heat insulation, low density and environmental protection. Through the modification of polyvinyl acetate to improve its water resistance and other aspects of performance, while using different particle size hollow microspheres in thermal insulation, strength and other aspects of the performance difference, developed a can be directly coated inside the hull , With self-adhesive insulation materials. After being practically used in recent years, the insulation material can effectively solve the problem of condensation on the hull of the domestic shipbuilding industry, improve the cabin working environment and have good social and economic benefits.
