Problems solved by technology

[0004] However, the above method is to apply the adhesive on the surface of the inner lining without compounding the PVC profile through a special extruder, the bonding between the metal and the PVC is uneven, the bonding strength is not high, 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 PVC (Polyvinyl Chloride) sectional material with surface coated with a metal film. The PVC sectional material with the surface coated with the metal film is prepared by material mixing, co-extrusion, vacuum cooling and sizing, coating of an aluminum film on the surface of the sectional material, cutting and molding. According to the preparation method provided by the invention, a PVC raw material and hot melt adhesive are compounded together by a way of co-extrusion, 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 preparation method of a PVC profile coated with a metal film on the surface, 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...
