Description
Technical field
The present invention relates to core material and manufacture method thereof for a kind of halogen-free flameproof aluminium-plastic panel.
Background technology
Due to the loss of life and personal injury that causes of fire of building and property damage in recent years, have unprecedented soaring, the fire-retardant and fire protection requirement that country has also strengthened structure material.Finishing material for exterior wall must reach certain fp grade.Aluminium-plastic panel, owing to having light weight, the advantage such as corrosion-resistant, heat insulation, has obtained development rapidly as a kind of building and ornament materials.For fire-retardant requirement, the flame-retardant aluminum plastic plate of low cigarette, Halogen also develops, and for example patent CN02113998.9 has disclosed the special-purpose novel material of polyolefine aluminium-plastic panel of being manufactured low cigarette, halogen-free flameproof by inorganic combustion inhibitor magnesium hydroxide, Hydroxide Filled Polyolefin.This class material is the main products of flame-retardant aluminum plastic plate in the market.For halogen-free flameproof aluminium-plastic panel core, reach high flame retardant resistance, must strengthen the loading level of inorganic combustion inhibitor.High loading level can cause and add stopping composition and extrude the mobility that adds man-hour, has influence on extrusion efficiency, increases the quality of energy consumption and infringement aluminium-plastic panel, and high loading level can cause higher density simultaneously, has increased aluminium-plastic panel weight, can have influence on the use of aluminium-plastic panel.
For reducing the quality of aluminium-plastic panel, patent CN1014757 has disclosed foaming plastic-aluminum plate resistance combustion core, is to adopt chemical foaming agent, in extrusion, by the decomposition of whipping agent, produces gas and foams.Although the method can be manufactured the core of foaming, the foam of foaming is larger and inhomogeneous, the intensity of core after impact foaming.Simultaneously due to whipping agent temperature, control comparatively strictly, can not at higher temperature, foam, otherwise can cause the failure of foaming, so extrusion temperature need to strictly control, this will cause the Efficiency Decreasing of extruding, and affects the speed of extrusion board.
Therefore, develop a kind of feasible foaming system, reduce the size of foaming foam, the reduction of the mechanical property of materials that minimizing causes due to foaming, meanwhile, foaming can not be subject to the control of temperature, can within the scope of wider processing temperature, foam, enhance productivity, seem and there is very large necessity.
