Embodiment 1

[0026] Embodiment 1: Prefabricate the core material 1 of the vacuum insulation panel first, and the core material is glass fiber, fumed silica, chemically deposited nano-silica, open-cell polyurethane foam or open-cell phenolic foam. Then put the prepared vacuum insulation board core material into the vacuum packaging bag 2 after drying. membrane. Next, the core material is heat-sealed in a vacuum packaging bag 2 at a vacuum degree of less than 100 Pa, preferably at a vacuum degree of less than 0.2 Pa. Then fold the excess edge of the vacuum packaging bag according to the shape of the core material, and use rubber-type pressure-sensitive adhesive, polyurethane adhesive, polyacrylate adhesive, hot-melt adhesive or epoxy resin glue to fold the excess edge of the vacuum packaging bag Adhesive fixation. Mix 100 parts of polyether or polyester polyol, 10 parts of pentane, 3 parts of hard foam silicone oil, 1 part of triethylenediamine, and 1 part of dibutyltin dilaurate; then add...

Abstract

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.

Description

technical field [0001] The invention relates to a vacuum insulation panel (VIP panel) insulation material, in particular to a puncture-resistant vacuum insulation panel and a preparation method thereof. Background technique [0002] Vacuum insulation panel (VIP panel) is a high-efficiency and energy-saving high-tech vacuum insulation material obtained by packaging the insulation core material in a vacuum packaging bag. Since the heat transfer caused by air convection is effectively avoided, the thermal conductivity is greatly reduced compared with traditional thermal insulation materials (vitrified beads, polystyrene board, polyurethane foam, etc.), generally at 0.008 W / (m K ) below, has very excellent thermal insulation performance. Compared with other insulation materials, vacuum insulation panels have the advantages of small size, thin thickness, light weight and low thermal conductivity, so they have attracted extensive attention in the fields of building exterior wall ...
