Embodiment Construction

[0013] Such as figure 1 Described, the pre-coating film that is used for building heat preservation of the present invention, is made of EVA hot-melt adhesive layer 2, BOPP film layer 3 and the aluminum layer 4 evaporated on BOPP film layer 3 successively from inside to outside; The BOPP film layer Contains UV absorbing masterbatch 2-(2'-hydroxy-3',5'-di-tert-phenyl)-5-chlorinated benzotriazole 1wt%~3wt% and flame retardant melamine cyanurate 2wt~5wt %. The thermal insulation material whose surface is coated with the pre-coated film of the present invention consists of a polyurethane thermal insulation layer 1, an EVA hot-melt adhesive layer 2, a BOPP film layer 3 and an aluminum layer vapor-deposited on the BOPP film layer 3 from the inside to the outside. 4 Composition; the EVA hot melt adhesive layer is hot melted and applied to the surface of the insulation layer under high temperature and high pressure conditions, which can reflect the heat radiation of sunlight and ult...

Abstract

The invention discloses a pre-coating film for the thermal insulation of buildings, which comprises a hot melt adhesive layer, a base film layer and a metal layer in sequence, wherein the hot melt adhesive layer is made of ethylene-vinyl acetate (EVA), the base film layer is a biaxially-oriented polypropylene (BOPP) film and a biaxially-oriented polyester (BOPP) film; the metal layer is an aluminium layer evaporated on the base layer. The invention further discloses a thermal insulation material coated with the pre-coating film on the surface, and comprises a thermal insulation layer, the hot melt adhesive layer, the base film layer and the metal layer in sequence from interior to exterior. The invention provides the anti-ultraviolet and flame-retardant pre-coating film applicable to the building field, which can be used for thermal insulation of an external wall and a roof; the aluminum plated pre-coating film is pasted on the outer surface of the thermal insulation material, so that the building thermal insulation material is convenient to use, superior in thermal insulation and energy saving effects, easy to assemble and disassemble and low in cost.

Description

technical field [0001] The invention relates to a precoat film used for building heat preservation and a thermal insulation material coated with the precoat film. Background technique [0002] Polyurethane thermal insulation material is currently the best thermal insulation material in the world. Rigid polyurethane has excellent properties such as light weight, low thermal conductivity, good heat resistance, aging resistance, easy bonding with other substrates, and no molten droplets when burned. It is widely used in roofs, walls, and ceilings of buildings in European and American countries , floors, doors and windows, etc. as thermal insulation materials. About 49% of the building insulation materials in developed countries such as Europe and the United States are polyurethane materials, while in my country this proportion is still less than 10%. As a polymer material with excellent performance, polyurethane insulation material has become the fifth largest plastic after ...
