Abstract

The invention discloses a PVC aluminum molding co-squeezing sectional material which is built by nonferrous metal enfolded with PVC plastic. Its production techniques includes following steps: A. feeding which includes mixing the PVC resin and aiding agents by formulation and flowing in to squeezer from feeding hopper; B. inner liner processing which includes heating after laying the adhesives on the surface of the inner liner then going into squeezer co-squeezing mould by the transferring belt; C. co-squeezing, shaping in vacuum, cooling to form the shape which include that the PVC mixed material goes through the co-squeezing mould after the heating and plasticizing in the squeezer, then squeeze the mixed material to the surface of the inner liner and obtain the product by vacuum shaping and cooling shaping, dragging. It maintains the rigidity meanwhile has a light weight and a stainless inner liner due to the adoption of aluminum or alumiunum alloy which is truly avirulent and environmental. It is also capable of multi-cavity cross section which makes the windows not easy to deform, distort, and sag.

Description

technical field [0001] The invention relates to a profile and a preparation method thereof, in particular to a PVC-aluminum-plastic co-extruded profile and a preparation method thereof. Background technique [0002] The wooden doors and windows and metal doors and windows used in the door and window building materials in the past have been eliminated. Now the aluminum alloy doors and windows and plastic steel doors and windows are widely used in the market. The air tightness and water tightness have not reached the ideal state. Aluminum alloy doors and windows and plastic steel doors and windows have their own defects that are difficult to overcome. Plastic steel doors and windows have good heat insulation performance, but their strength is insufficient. Difference. Today's doors and windows are developing towards personalized consumption such as energy saving, heat preservation, and decoration. Aluminum alloy doors and windows and plastic steel doors and windows have been...
