Thermal insulation rock wool board with density gradient and manufacturing method of thermal insulation rock wool board
The invention discloses a thermal insulation rock wool board with a density gradient and a manufacturing method of the thermal insulation rock wool board in the technical field of the rock wool boards. The density of the rock wool board is distributed in the mode that in the thickness direction, the density of the middle is small and the density of the two sides is large, the density change from the middle to any side is in gradient; the rock wool board comprises the following raw material in parts by weight; 50-60 parts of basalt, 15-20 parts of quartz sand, 10-15 parts of iron ore, 10-15 parts of perlite, 10-25 parts of phenolic resin adhesive, 10-15 parts of silicon dioxide aerogel and 4-6 parts of water repellent; through a pendulum machine, multiple cotton felts with different layer numbers are folded, and then pressed into cotton felts with the same thickness in advance, so that the density of the cotton felts with more layers is large, the density of the cotton felts with fewerlayers is small, and then the cotton felts with small density in the middle and large density on two sides are stacked and pressed to be compounded together. The rock wool board with the density gradient prepared through the preparation method provided by the invention has the advantages of good breaking resistance, good deformation resistance, good thermal insulation performance and good waterproof performance.
本发明公开了岩棉板技术领域的一种具有密度梯度的保温岩棉板及其制造方法，岩棉板的密度沿厚度方向以中间密度小、两边密度大的方式分布，且中间到任意一边的密度变化呈梯度变化，岩棉板包括如下重量组分的原料：玄武岩50‑60份、石英砂15‑20份、铁矿石10‑15份、珍珠岩10‑15份、酚醛树脂粘接剂10‑25份、二氧化硅气凝胶10‑15份和憎水剂4‑6份，通过摆锤机折叠出多种层数不同的棉毡，再将它们先预压成厚度相同的棉毡，使得层数多的密度大，层数少的密度小，然后以中间密度小、两边密度大的方式堆叠后，再经压合将它们复合在一起，本发明制备出的具有密度梯度的保温岩棉板，具有更好抗折断性能和更好抗形变性能的优点，还具备良好的保温和防水性能。
