Problems solved by technology

[0004] However, the above-mentioned method is to apply adhesive on the surface of the inner lining without special extruder processing, the adhesive effect of the adhesive is not good, the bonding between metal and PVC is uneven, and the bonding strength is not high; Without treatment, it is easy to cause the metal layer to peel off, 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 film-coated PVC (polyvinyl chloride) profile. The preparation method comprises the following steps: mixing raw materials, extruding a PVC profile, shaping by cooling in vacuum, coating the profile with a hot melt adhesive and a metal film, and cutting to prepare the metal film-coated PVC profile. According to the preparation method, PVC raw materials and the hot melt adhesive are processed by adopting separate extruders respectively, the bonding strength of the hot melt adhesive is high, the bonding performance of the metal film is relatively uniform and strong, the layering phenomenon is not easily caused, and the continuous production from the hot melt adhesive and PVC raw material powder to the metal film-coated PVC profile can be realized.

Description

technical field [0001] The invention relates to a method for preparing a metal-coated PVC profile, which 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 long-term sunlight exposu...
