Abstract

The invention discloses a high-strength and flame-resistant vacuum insulating board which comprises core material and a sealing film wrapped outside the core material. The core material comprises an intermediate layer, thermal insulation material layers are respectively superposed above and below the intermediate layer, the sides of the insulation material layers above and below the intermediate layer facing toward the intermediate layer are corrugated surfaces, corrugated depressions of the corrugated surfaces are filled with silicon dioxide aerogel and getter, the sides of the insulation material layers back against the intermediate layer are planes, and the planes are adhered with reflection layers. The vacuum insulating board of the invention has a stable structure, better impact-resistant property, strong flame resistance, good moderated and high temperature resistant performance and long service life, and can be repetitively pumped to use.

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to a high-strength vacuum thermal insulation panel and a preparation method thereof. Background technique [0002] Existing vacuum insulation panels (VIP panels) Existing vacuum insulation panels are usually provided with insulating core materials in multi-layer shell bags, the multi-layer shell bags are evacuated, and gas adsorbents are arranged in the multi-layer shell bags. Increasing the vacuum degree in the multi-layer shell bag can significantly reduce the thickness of the heat insulation layer under the condition that the heat insulation effect of the non-vacuum heat insulation board is the same. [0003] For example, the Chinese utility model patent 200420053407.2 discloses a vacuum insulation panel, which includes an outer shell and an insulating core material arranged in the vacuum outer shell. The core material includes silica airgel and glass fibers, and the glass fibers ...
