Embodiment Construction
[0024] see figure 1 , a new and old plastic layered co-extrusion color profile in the present invention is characterized in that the profile is formed by layered fusion co-extrusion of new plastic layer 2 and old plastic layer 1, and the new plastic layer 2 is coated on the old plastic layer 1's outer surface. The new plastic layer 2 is made of new polyvinyl chloride plastic, and the old plastic layer 1 is made of regenerated white polyvinyl chloride plastic. The new plastic layer 2 accounts for about 20% of the total mass of the profile, and the old plastic layer 1 accounts for approximately 80% of the total mass of the profile.
[0025] The profiles of the present invention can be the structures of various existing profiles for plastic-steel doors and windows and profiles for plastic-steel decoration.
[0026] The raw material of the new plastic layer 2 (referred to as new plastic) is configured according to conventional technology. After the multi-component raw materials ...

A new / recycled plastic layered compatible co-extruded color profile and method for forming the same are disclosed. The profile is formed by a new plastic layer and a recycled plastic layer through layering compatible co-extrusion; and the new plastic layer covers the recycled plastic layer. The new plastic layer is formed by adopting new polyvinyl chloride plastics, while the recycled plastic layer is formed by adopting recycled white polyvinyl chloride plastics. The new plastic layer accounts for about 20% of the total weight of the profile, while the recycled plastic layer accounts for about 80% of the total weight of the profile. The new plastic layer of the layered compatible co-extruded color profile provided by the invention has a certain thickness so that the recycled plastic layer is not exposed from the surface in the use process of assembling and welding the profile. The recycled plastics are covered by the new plastics so that appearance shortcomings in recycling the used plastics for fabricating the profile are overcome, and simultaneously, material waste due to applying the new plastics to fabricate the profile completely is reduced.
Description
technical field [0001] The invention relates to a new and old plastic layered co-extrusion colored section bar and a forming method thereof, and its scope of application is mainly as a section bar for plastic-steel doors and windows and a section bar for plastic-steel decoration. Background technique [0002] At present, plastic-steel profiles are generally made of new plastics or recycled old plastics alone or mixed. After the multi-component raw materials of new plastics are prepared according to a specific formula, they must first be mixed to make the molecules of the raw materials of each component permeate and distribute evenly. The mixed materials are the new plastics used for extrusion molding. The preparation of the new plastic can achieve the properties of pure surface color, bright and delicate, and resistance to ultraviolet light. However, the price of various raw material components is relatively high, and the cost of making profiles entirely with new plastics i...
