Problems solved by technology

[0004] However, the scheme 1) in the prior art can only be used for thermoforming usually. Although the obtained product has high rigidity and high dimensional stability, the appearance quality of the parts after thermoforming is poor, and post-processing is usually required ; And the product that scheme 2) obtains, although appearance effect is better, but the rigidity of glass fiber reinforced resin material and dimensional stability can't meet the requirement of thin-walled product

preparation example Construction

[0030] Correspondingly, an embodiment of the present invention also provides a method for preparing a plastic frame of an electronic device casing and / or module, which specifically includes:

[0031] Baking any carbon fiber reinforced resin composite material provided by the embodiments of the present invention at 80-90°C for 2-4 hours;

[0032]Plasticize and melt the carbon fiber reinforced resin composite material after baking; specifically, the process can be: add the carbon fiber reinforced resin composite material after baking into the hopper of the injection molding machine, and set the temperature of each section of the injection molding machine , so as to plasticize and melt the plastic;

[0033] The molten carbon fiber reinforced resin composite material is injected into a mold with a surface temperature of 100-170° C. to obtain a plastic frame of an electronic equipment case and / or module.

Embodiment 1

[0042] 15wt% carbon fiber, 69.9wt% 1017D type PC+ABS alloy, 12wt% lubricant PBT, 2wt% toughening agent 24MA005, 0.1wt% antioxidant 1076, 0.2wt% antioxidant 627, 0.5wt% lubricant PETS , 0.3wt% toner M900 are fully mixed, respectively put into a twin-screw extruder, extruded and granulated using the extruder at 230-250° C. to obtain a carbon fiber reinforced resin composite material, dried and packaged for use.

Embodiment 2

[0044] 18wt% carbon fiber, 63.8wt% 1017D type PC+ABS alloy, 14wt% lubricant PBT, 3wt% toughening agent 24MA005, 0.1wt% antioxidant 1076, 0.2wt% antioxidant 627, 0.6wt% lubricant PETS , 0.3wt% toner M900 are fully mixed, respectively put into a twin-screw extruder, extruded and granulated using the extruder at 230-250° C. to obtain a carbon fiber reinforced resin composite material, dried and packaged for use.

Abstract

The invention discloses a carbon fiber reinforced resin composite material, use thereof and a preparation method of a rubber frame of an electronic equipment enclosure and/or a module, and relates to the technical field of carbon fiber reinforced resin composite materials. A product injection-molded by the carbon fiber reinforced resin composite material can not only meet the requirements of high rigidity and high dimensional stability, but also obtain high-light spraying-free effects. The carbon fiber reinforced resin composite material is prepared from the following components: 15-25wt% of carbon fibers, 50-70wt% of PC+ABS alloy, 10-20wt% of a smoothing agent, 2-4wt% of a flexibilizer and 0.3-0.5wt% of an antioxidant, wherein the melt index of the PC+ABS alloy is greater than and equal to 40. The carbon fiber reinforced resin composite material disclosed by the invention is applicable to the injection molding of thin-wall products.

Description

technical field [0001] The invention relates to the technical field of carbon fiber-reinforced resin composite materials, in particular to a carbon fiber-reinforced resin composite material and its application, and a method for preparing electronic equipment casings and / or plastic frames of modules. Background technique [0002] The development and application of new material technology in TV is often closely related to the changes in the structure and form of TV products. In recent years, the structure of TVs has undergone significant changes with each passing day, and the trend of structural changes is very clear, that is, ultra-narrow and ultra-thin, which requires the ultra-thin and ultra-narrow design of modules and front and rear shells. Therefore, it is necessary to reduce the wall thickness of the product, cancel or reduce the height of the ribs. With these changes in design trends, if the previous material scheme is still used, the rigidity and dimensional stability...
