水性工业隔热涂料的研制与应用

Preparation and Use of Water-borne Industrial Thermal Insulating Coating

介绍了水性工业隔热涂料的配方、工艺、应用方法,通过试验确定了以有机硅乳液和丙烯酸乳液混配作胶黏剂,以空心玻璃微珠为主、配合膨胀蛭石、玻化微珠、无机纤维、硅藻土等为隔热填料,颜基比为6∶4。在输热管道上涂覆隔热涂层3 mm,在管内温度200℃条件下,隔热温差达45℃,节能15%左右。

This paper introduces the compositions, technology and application method of water-borne industrial thermal insulation coatings. It is determined that with silicone emulsion and acrylic emulsion as mixing binders, with hollow glass beads as main insulation filler together with expanded vermiculite, glass micro-beads, inorganic fibers and diatomite, under the pigment and binder ratio of 6 ： 4, and coating 3 mm on the heat supply pipeline, the effect of thermal insulation can be gotten： the temperature difference reaching 45 ℃ and energy saving reaching 15%.
