Puncture-resistant vacuum insulation board and manufacturing method thereof

The invention discloses a puncture-resistant vacuum insulation board. The puncture-resistant vacuum insulation board comprises a puncture-resistant layer, a vacuum encapsulation layer and a core material inside the vacuum encapsulation layer. The puncture-resistant layer is made of polyurethane foam materials, bonds to the surface of the vacuum encapsulation layer, and is obtained through a foaming reaction of polyether polyol or polyester polyol and polyisocyanates. Meanwhile, the invention further discloses a manufacturing method of the vacuum insulation board. The obtained vacuum insulation board has good puncture resistance, largely reduces the high defective rate caused by puncture, scrapping and rubbing when the vacuum insulation board is conveyed and used, lowers the construction difficulty, has excellent insulation property, and is suitable for being applied to and popularized in various heat-preservation places.
