Embodiment 1
[0038] In the embodiment of the present invention, the raw material is polyvinyl chloride PVC as an example. Its composition and proportioning ratio are calculated by weight percentage:
[0039] A: The basic process steps for manufacturing plastics are as follows:
[0040] 1. Take the main material polyvinyl chloride PVC: 80, auxiliary materials: take the filler as heavy calcium carbonate: 8, take the stabilizer as lead: 4, take the plasticizer as CPE: 4, take the lubricant as paraffin: 3, Take the auxiliary agent as fluorescent whitening powder: 1. Put the above-mentioned main materials and auxiliary materials into the mixer and mix at high temperature, the mixing temperature is 120 degrees, and it is carried out at the speed of 1000-1500r / m;
[0041] 2. Put the above-mentioned mixed raw materials into the granulator, and produce plastic particles through the granulator, and the granulation temperature is carried out at a temperature of 120 degrees;
[0042] 3. Extrude the...
Embodiment 2
[0061] Embodiment 2: its composition and proportioning are calculated by weight percentage:
[0062] In this embodiment, polyethylene PE is used as the main material: 82, auxiliary materials: take filler as light active agent: 7, take stabilizer as barium: 4, take plasticizer as AVR: 4, take lubricant as poly Ethylene wax: 2.5, the additive is titanium dioxide: 0.8 for mixing, the mixing temperature is 130 degrees; the granulation temperature is 150 degrees, and the heating and extrusion temperature is 180 degrees. Using the process steps of processing plastic substrate plates in Example 1 and the process steps of processing and coating aluminum coils in Example 1, and adopting the composite process of plastic substrate plates and aluminum coils in Example 1 to make aluminum plastic Composite decorative gussets are stable in quality and meet the required physical properties of gussets.
Embodiment 3
[0063] Embodiment 3: its composition and proportioning are calculated by weight percentage:
[0064] Adopt polyester PET in the embodiment of the present invention: 85, get filler and be heavy calcium carbonate: 6, get stabilizer and get three salts: 3, get plasticizer and get DOP: 3, get lubricant and get paraffin wax: 2, Take additives as pigments: 0.5. The above ingredients were stirred at a high temperature of 150 degrees, granulated at a temperature of 180 degrees, and extruded at a temperature of 200 degrees. Using the manufacturing process steps in Examples 1 and 2, it is also processed into an aluminum-plastic composite decorative gusset that meets the quality index. This kind of gusset not only has the characteristics of luxury, elegance, beauty and durability of aluminum gusset, but also has the same unparalleled market competitive price as plastic gusset. trend.
