Embodiment 1

[0026] Each component is formulated according to: component name mass parts

[0027] PP powder 5

[0028] LPPE 5

[0029] C a CO 3 (nanoscale) 80

[0030] PE wax 6

[0031] Paraffin 1

[0032] Coupling agent 1

[0033] Brightener 2

[0034] Accurately weighed spare; the C a CO 3 Place in a high-speed kneader for high-speed mixing and drying; add coupling agent for activation treatment; add dispersant, carrier resin, brightener, etc. for high-speed kneading, kneading to C a CO 3 Completely prepared for coating, wetted and discharged for later use; the kneaded material was poured into a parallel twin-screw extruder for extrusion, water-cooled, air-dried, pelletized, air-dried, inspected, packed and put into storage. By adopting the invention, the dispersibility of the special filler masterbatch for the aluminum-plastic plate is good, the rigidity and impact ...

Abstract

A mother filler for the aluminium-plastic plate to increase smoothness and cohesive force is prepared from nano-CaCo3 resin as carrier, coupling agent and disperser through high-speed kneading, cooling, extruding, cooling in water, drying, and granulating.

Description

1. Technical field [0001] The invention relates to a kind of special filling masterbatch used in the sandwich plastic of aluminum-plastic plate. The invention also relates to a method for preparing the masterbatch. 2. Background technology [0002] Aluminum-plastic panel is a new type of decorative material, which has the advantages of quick and convenient installation, strong weather resistance, and good decorative effect. However, due to the high price, it hinders the popularization and promotion of aluminum-plastic panels. However, the addition of ordinary filler masterbatch is prone to defects such as uneven surface and poor bond strength between plastic plate and aluminum plate. Therefore, it is very important to develop a special filler masterbatch for aluminum-plastic panels that has good dispersion, does not affect its bond strength after adding, and reduces its cost. 3. Contents of the invention [0003] The purpose of the present invention is to provide a spec...
