preparation example Construction
[0055] The invention provides a preparation method of a rain shield, referring to the following steps:
[0056] 1) Add PET materials, fillers and additives to the blender, stir and mix at a speed of 600rpm, and then send it to a granulation extruder, extrude and granulate at 220°C to obtain a composite masterbatch;
[0057] 2) The composite masterbatch is sent to the extruder, melted and plasticized, and then extruded through a common rectangular die to obtain a rain shield.
Embodiment 1
[0062] refer to Figure 1-4, an embodiment provided by the present invention: a car reservation service device, including a base 1, a stable structure 2 and a body 3, the outer walls of both sides of the base 1 are provided with multiple sets of movable grooves 103, the base 1 can be in direct contact with the ground , and then it can transfer its own sliding function to the whole structure, and through it, the various parts in the device can be combined together, so that it forms a complete whole, and then has perfect functions, and the setting of the movable groove 103 is convenient The installation of the stable structure 2 is ensured, and one end of the movable groove 103 can become smaller, which is the same as the size of the movable block 201 inside the stable structure 2, but due to the limitation of the limiting plate 202, the whole stable structure 2 can be prevented from moving from the movable groove. The inside of 103 falls off, and the inside of the movable groov...
Embodiment 2
[0065] A parking space management device, the specific implementation of which is the same as that of Example 1. The difference from Example 1 is that the raw materials for the preparation of the rain shield 602 are calculated by weight percentage, including: 92% of PET material, 7.5% of filler, N-doped graphite ene quantum dots 0.5%.
[0066] PET material, grade DY-108, was purchased from Dongguan Dayue Plastic Technology Co., Ltd.
[0067] The filler is nano-montmorillonite and nano-titanium dioxide with a weight ratio of 1:0.6.
[0068] The weight percentage of titanium dioxide in the nanometer titanium dioxide is 93%.
[0069] Nano-montmorillonite was purchased from Xingyuan Mineral Powder Processing Factory in Lingshou County; nano-TiO2, model R105, was purchased from DuPont, USA.
[0070] N-doped graphene quantum dots were purchased from Nanjing Xianfeng Nano Material Technology Co., Ltd.
[0071] For the preparation method of the rain shield, refer to the following s...
