Inorganic fiber composite thermal insulation material and preparation method thereof
The invention relates to the field of thermal insulation materials, and discloses an inorganic fiber composite thermal insulation material and a preparation method thereof. The composite thermal insulation material comprises a sheet-shaped matrix formed by flocculation and entanglement of inorganic fibers; and an inorganic filler and a modified thermal insulation filler (polyacrylic acid modified polymetallic compound) dispersed in the matrix. The composite thermal insulation material contains the polyacrylic acid modified multi-metal compounds, on one hand, the multi-metal compounds are mutually doped, so that the thermal conductivity of the material can be reduced; on the other hand, in the material forming process, polyacrylic acid can promote the inorganic fibers to flocculate to a proper degree, so that the inorganic filler/modified heat insulation filler is wrapped in a matrix, the retention assisting effect is achieved, and the retention rate and stability of the inorganic filler/modified heat insulation filler are remarkably improved. In conclusion, the inorganic fiber composite thermal insulation material disclosed by the invention has excellent low thermal conductivity, high temperature resistance and strength, and meets the requirement of the thermal insulation material for keeping relatively good thermal insulation performance in a severe environment.
本发明涉及隔热材料领域，公开了一种无机纤维复合隔热材料及其制备方法。该复合隔热材料包括：由无机纤维絮聚后缠结而成的片材状基质；以及分散于基质中的无机填料和改性隔热填料（聚丙烯酸改性多金属化合物）。本发明复合隔热材料含有聚丙烯酸改性多金属化合物，一方面，多金属化合物相互掺杂可降低材料导热率；另一方面，在材料成型过程中聚丙烯酸能够促进无机纤维发生适当程度的絮聚，从而将无机填料/改性隔热填料包裹于基质中，起到助留的效果，从而显著提高无机填料/改性隔热填料的留着率和稳定性。综上，本发明无机纤维复合隔热材料具有出色的低导热率、耐高温性和强度，满足了隔热材料在苛刻环境下保持较好隔热性能的要求。
