Inorganic lightweight aggregate insulation board with multilayer structure and preparation method thereof
The invention discloses an inorganic lightweight aggregate insulation board with a multilayer structure. The insulation board comprises a surface enhancement layer, a thermal insulation layer and a bottom surface enhancement layer, wherein the thermal insulation layer is prepared from the following components in parts by weight: 360-450 parts of 20-30-mesh expanded perlite, 120-160 parts of cement and 20-60 parts of a modifier; the surface enhancement layer and the bottom surface enhancement layer comprise the following components in parts by weight: 50-100 parts of 50-70-mesh expanded perlite or slag, 100 parts of cement and 10 parts of a modifier; and the modifier comprises a cement reinforcing agent and an emulsion. According to the inorganic lightweight aggregate insulation board with the multilayer structure and the preparation method thereof, the produced insulation board is compact and smooth in appearance, the compression strength, the breaking strength and the water resistance can be improved, and the affinity with cement mortar is enhanced; the structure and thermal insulation are integrated, the internal dry density is low, the thermal insulation effect is good, the upper and lower surface strength is high, and a protective layer is made; and multiple times of material distribution and one-time forming are achieved, the integrity of the multilayer structure insulation board is guaranteed, and interface stripping is prevented.
本发明公开了一种多层结构的无机轻集料保温板，该保温板包括表面增强层、保温层和底面增强层；所述保温层组分以重量计，包括20‑30目的膨胀珍珠岩360份‑450份，水泥120‑160份，改性剂20份‑60份；表面增强层和底面增强层组分以重量计，包括50‑70目的膨胀珍珠岩或者炉渣50‑100份，水泥100份，改性剂10份；所述改性剂包括水泥增强剂和乳液。本发明一种多层结构的无机轻集料保温板及其制备方法，生产的保温板表观致密、平滑，能提高抗压、抗折强度和耐水性，增强与水泥砂浆的亲和性；结构与保温一体化，内部干密度低、保温效果好，上下表面强度高，做保护层；多次布料一次成型，保证多层结构保温板的整体性，防止出现界面剥离。
