Abstract

The invention discloses a core layer material for a flame-retardant aluminum-plastic plate, which comprises the following components in parts by weight: 20-40 parts of polyethylene, 10-20 parts of a compatibilizer, and 30-50 parts of a flame retardant. The core layer material for the flame-retardant aluminum-plastic plate has good flame-retardant effect, does not contain halogen flame retardants, and will not cause secondary pollution.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a core layer material for flame-retardant aluminum-plastic panels and a preparation method thereof. Background technique [0002] The aluminum-plastic panel is a kind of architectural decorative panel composed of a front aluminum metal panel, a middle polymer plastic core material and a back aluminum metal bottom plate through polymer film and high temperature and high pressure. At present, the aluminum-plastic panels on the market include ordinary aluminum-plastic panels and flame-retardant aluminum-plastic panels. The core material of ordinary aluminum-plastic panels is mainly made of polyethylene, and the sales volume accounts for about 90% of the domestic market of aluminum-plastic panels. However, this product is not flame-retardant, and its oxygen index is 16-18. It is easy to drip after burning, and it is easy to cause fire spread. [0003] Foreign construction markets ha...
