Capsule type composite thermal insulation material and preparation method thereof
The invention discloses a capsule type composite thermal insulation material and a preparation method thereof. The capsule type composite thermal insulation material comprises ultralight solid waste modified foaming cement paste, chopped fibers and capsule particles, wherein the ultralight solid waste modified foaming cement paste mainly comprises carbide slag, coal gangue powder, cement, water, a water reducing agent, a foaming agent, a foam stabilizer and an early strength agent; and the capsule particles are composed of capsule walls and core materials wrapped in the capsule walls. According to different materials used by the capsule walls, used capsules can be classified into microcapsules (with a wall material size in a range of 5-200 microns) and conventional capsules (with a wall material size of about 1 cm). The wall material of the microcapsules is an inorganic material or a high polymer material, the wall material of the conventional capsules is a PE transparent plastic shell, and the core materials of the capsules are both an aerogel material. According to the invention, the problems that an existing thermal insulation material is poor in toughness, poor in thermal insulation effect, poor in flame retardance, high in cost and tedious in manufacturing process are solved; and meanwhile, solid waste resource utilization is achieved, and the green and environment-friendly building development concept is accorded with.
本发明公开了一种胶囊型复合保温材料及其制备方法，其中胶囊型复合保温材料包括超轻固体废弃物改性发泡水泥浆体，短切纤维，胶囊颗粒。其中，超轻固体废弃物改性发泡水泥浆体主要包括电石渣、煤矸石粉、水泥、水、减水剂、发泡剂、稳泡剂以及早强剂。胶囊颗粒由胶囊壁和包裹在内部的芯材组成。根据胶囊壁所用材料的不同，分为微胶囊(壁材为5～200μm)和常规胶囊(壁材约为1cm)。其中微胶囊的壁材为无机材料或高分子材料，常规胶囊的壁材为PE透明塑料壳，胶囊芯材均采用气凝胶材料。解决了现有保温材料韧性差、保温效果差、阻燃性差、成本高以及制作过程繁琐的问题，同时实现了固废资源化利用，符合绿色、环保的建筑发展理念。
