preparation example Construction

[0015] The preparation method of the remote control shell material of the present invention, 1) soaking the composite antibacterial agent in the coupling agent, then drying the ABS matrix resin and the soaked composite antibacterial agent at 70-80°C for 4-5h respectively; 2 ) According to the formula, other additives except the composite antibacterial agent are uniformly mixed with the ABS matrix resin, and then extruded and granulated with the composite antibacterial agent through a screw extruder to obtain an ABS antibacterial composite material.

[0016] Because the glass fiber will cause damage to the ordinary screw, the screw extruder is reinforced, and the screw length-to-diameter ratio is 37-45. The temperature in zone one: 175-185°C, the temperature in zone two: 185-195°C, the temperature in zone three: 205-215°C, the temperature in zone four: 215-225°C, the temperature in zone five: 205-215°C, the temperature in zone six: 195-205°C, the rotational speed of the screw i...

Abstract

The invention provides a remote controller shell material with an antibacterial function and a preparation method of the remote controller shell material. The remote controller shell material is prepared from the following components in parts by weight: 81 to 89 parts of ABS matrix resin, 4 to 12 parts of a composite antibacterial agent, 0.1 to 0.14 part of a coupling agent, 2 to 4 parts of a compatilizer, 0.2 to 0.3 part of an antioxidant, and 0.2 to 0.4 part of a lubricant. The preparation method comprises the following steps: (1) wetting the composite antibacterial agent in the coupling agent, and then respectively drying the ABS matrix resin and the wetted composite antibacterial agent under the condition of 70 to 80 DEG C for 4 to 5 hours; (2) uniformly mixing other auxiliaries except for the composite antibacterial agent in the formula with the ABS matrix resin to obtain a mixture, and extruding and granulating the mixture and the composite antibacterial agent through a screw extruding machine to obtain an ABS antibacterial composite material. The remote controller shell material disclosed by the invention adopts the novel composite antibacterial agent, so that the antibacterial slow-release property is improved, the weather fastness is high, and the intensity is high.

Description

technical field [0001] The invention belongs to the technical field of polymer resin materials with antibacterial function, and in particular relates to a remote control shell material with antibacterial function and a preparation method. Background technique [0002] ABS (Acrylonitrile Butadiene Styrenecopolymers, referred to as ABS, the Chinese name is acrylonitrile-butadiene-styrene copolymer) plastic, because of its good comprehensive physical properties, good chemical resistance, easy molding and processing, and low price, it can be realized The high-gloss effect is therefore widely used in the casing of electronic equipment. However, if it is used as a remote control casing, due to prolonged contact with human hands, it will cause bacteria to grow on the surface and increase the potential harm to the human body. Therefore, if a material with antibacterial function is used, the growth of bacteria on the surface of the remote control can be inhibited, and the risk of bac...
