Problems solved by technology

However, the inventor's research results show that when using maleic anhydride grafted polyethylene as a compound to produce flame-retardant hot-melt adhesives, if an alkaline metal oxidation auxiliary flame retardant or an alkaline metal oxidation smoke suppressant is added thereto, then It will cause the bonding strength of the flame retardant hot melt adhesive to decrease and become unstable

Abstract

The invention discloses a special flame-retardant hot melt adhesive for an aluminum-plastic panel. The flame-retardant hot melt adhesive comprises components in parts by weight as follows: 10-30 parts of polyethylene grafted maleic anhydride, 20-40 parts of polyethylene resin, 5-10 parts of ethylene-octylene copolymers, 10-15 parts of a brominated flame retardant, 5-10 parts of a non-alkaline metal oxide assistant fire retardant and 5-10 parts of a non-alkaline metal oxide smoke suppressant. According to the special flame-retardant hot melt adhesive for the aluminum-plastic panel, the non-alkaline metal oxide assistant fire retardant and the non-alkaline metal oxide smoke suppressant are added to a mixture containing the polyethylene grafted maleic anhydride, the flame retardation property can reach the V0 level of UL94, the smoke density is only 50-60, the peeling strength is high, and the binding power durability is long. Besides, the invention further discloses a preparation method of the flame-retardant hot melt adhesive.

Description

technical field [0001] The invention relates to an adhesive and a preparation method thereof, in particular to a special flame-retardant hot-melt adhesive for aluminum-plastic panels and a preparation method thereof. Background technique [0002] Aluminum-plastic composite panel (hereinafter referred to as aluminum-plastic panel) refers to a multi-layer composite panel with plastic as the core layer (usually polyethylene material) and aluminum on both sides. The plastic core and aluminum are bonded by hot-melt adhesive film. The surface of the product is covered with a decorative and protective coating or film as the decorative surface of the product. Aluminum-plastic panels are widely used because of their light weight and high strength. [0003] In the fields of construction and decoration, the fire performance of aluminum-plastic panels has attracted more attention. Since the polyethylene core material in aluminum-plastic panels is not flame-retardant, in order to achieve...
