Problems solved by technology

[0004] However, the above-mentioned method is to apply the adhesive on the surface of the inner lining without special extruder processing, the adhesive effect of the adhesive is not good, the bonding between the metal and PVC is uneven, the bonding strength is not high, and it is easy to cause metal Layer by layer, and it is not easy to carry out continuous production
The prepared PVC-aluminum-plastic co-extruded profile has low plasticity and is not conducive to production and processing

Abstract

The invention relates to a preparation method of a metal coated PVC (Polyvinyl Chloride) sectional material for improving plasticity. The PVC sectional material with the surface coated with a metal film is prepared by material mixing, extrusion, vacuum cooling and sizing of the PVC sectional material, coating of hot melt adhesive on the surface of the metal film, coating of the metal film on the surface of the PVC sectional material, cutting and molding. According to the preparation method provided by the invention, a PVC raw material and the hot melt adhesive are respectively treated by a separate extruder, so that the bonding strength of the hot melt adhesive is high, the bonding of the metal film is uniform and strong, the bonding strength is high, delamination is unlikely to occur, and the continuous production of the hot melt adhesive, PVC raw material powder and PVC sectional material products with the surfaces coated with the metal films can be realized.

Description

technical field [0001] The invention relates to a method for preparing a metal-coated PVC profile with improved plasticity, and belongs to the technical field of composite profile preparation. Background technique [0002] The materials used in the doors and windows of housing construction have increasingly replaced the original wooden windows and steel windows with aluminum alloy or plastic steel, and the use of plastic steel doors and windows is more common. Plastic-steel doors and windows have many advantages, and are known as a new generation of energy-saving doors and windows rising after wooden windows, steel windows, and aluminum alloy windows. Compared with aluminum windows and steel windows, they are superior in sealing, heat preservation, and corrosion resistance. Coordinated with similar buildings, it has better aesthetics and can meet individual needs, and has good fire resistance and insulation. However, plastic steel profiles will age and change color under lo...
