Embodiment 1

[0018] A preparation process of modified plastic for heat dissipation grid with sterilization function, including the following steps:

[0019] (1) Weighing: Weigh the following raw materials: ASA rubber powder 90-100 kg, antistatic agent 1-2 kg, flame retardant 1-1.7 kg, antioxidant 2-3 kg, iodine powder 0.8-1.3 kg, photocatalyst 0.5-0.7 kg of powder, flame retardant is zinc borate, antioxidant is compounded by Ciba antioxidant 168 and phenolic antioxidant 1:1;

[0020] (2) Mixing: Mix the above raw materials mechanically for 15-20 minutes, at a mixing temperature of 100-110°C, and a vacuum degree of less than -0.05Mpa. Heating during mixing can facilitate the volatilization of water vapor inside the material and make the material more pure;

[0021] (3) Extrusion and granulation: The above mixture is plasticized through an internal mixer, the raw materials are extruded through a twin-screw extruder, water-cooled and air-dried, and the strip-shaped plastic is cut into pellets throug...

Embodiment 2

[0025] A preparation process of modified plastic for heat dissipation grid with sterilization function, including the following steps:

[0026] (1) Weighing: Weigh the following raw materials: 95 kg of ASA rubber powder, 1.2 kg of antistatic agent, 1.5 kg of flame retardant, 2.5 kg of antioxidant, 1 kg of iodine powder, 0.6 kg of photocatalyst powder, and zinc borate as flame retardant , Antioxidant is compounded by Ciba Antioxidant 168 and Phenolic Antioxidant 1:1;

[0027] (2) Mixing: Mix the above raw materials mechanically for 15-20 minutes, at a mixing temperature of 100-110°C, and a vacuum degree of less than -0.05Mpa. Heating during mixing can facilitate the volatilization of water vapor inside the material and make the material more pure;

[0028] (3) Extrusion and granulation: The above mixture is plasticized through an internal mixer, the raw materials are extruded through a twin-screw extruder, water-cooled and air-dried, and the strip-shaped plastic is cut into pellets th...

Abstract

The invention relates to the technical field of modified plastic preparation, in particular to a preparation process of a cooling grid modified plastic with a sterilization function. The preparation process includes the steps: weighing: weighing raw materials, by weight, 90-100 parts of ASA rubber powder, 1-2 parts of antistatic agents, 1-1.7 parts of flame retardants, 2-3 parts of antioxidants, 0.8-1.3 parts of iodine powder and 0.5-0.7 part of photocatalyst powder; mechanically stirring the raw materials for 15-20 minutes at the temperature of 100-110 DEG C under the vacuum degree lower than-0.05Mpa; plasticizing mixture by an internal mixer, extruding the raw materials by a twin-screw extruder, air-drying the materials after water cooling, and cutting strip-shaped plastics into particles by a granulating machine; screening, inspecting and storing the particles. The particles are prepared into a plastic grid, gas entering a vehicle can be purified and effectively sterilized, safetyof passengers in the vehicle is effectively protected, a preparation process of the plastic grid is simple, and the preparation efficiency of the plastic grid is improved.

Description

Technical field [0001] The invention relates to the technical field of modified plastic preparation, in particular to a process for preparing a heat dissipation grid modified plastic with sterilization function. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as the power source (or the use of conventional vehicle fuels, the use of new on-board power devices), the integration of advanced technologies in vehicle power control and driving, and the formation of advanced technical principles and Cars with new technology and new structure. [0003] The radiator grille is an indispensable part of every car. It is used for gas exchange inside and outside the car. When the gas is exchanged, only one dust filter is set between the outside air and the connecting pipe inside the car, which can only filter dust and cannot make the outside world toxic. Gas and bacteria removal. Summary of the invention [0004] The purpose of the present inven...
