Glass fiberboard and production method therefor
The present invention relates to a glass fiberboard and to a production method therefor, and more specifically, to technology for providing a glass fiberboard for vacuum heat insulation and a production method therefor, which have outstanding initial heat insulation performance and economic advantages through application of an optimized inorganic binder.
1. A method for producing a glass fiberboard, comprising:
preparing a mixture solution by stirring glass fibers and an inorganic binder solution;
obtaining an extract by removing water from the mixture solution; and
compressing and drying the extract,
wherein the inorganic binder solution comprises a mixture of aluminum sulfate and sodium hydroxide,
the inorganic binder is present in an amount of 0.1 wt % to 1 wt % based on the total weight of the inorganic binder solution, and
the glass fibers having a diameter of 4 μm-6 μm.
2. The method for producing a glass fiberboard according to claim 1 , wherein the mixture solution comprises an aluminum compound.
3. The method for producing a glass fiberboard according to claim 2 , wherein the aluminum compound is aluminum hydroxide.
4. The method for producing a glass fiberboard according to claim 2 , wherein a dried product of the aluminum compound is aluminum oxide.
