Problems solved by technology

Traditional high-gloss materials such as high-gloss ABS, PMMA / ABS, PC / ABS, etc. have low impact, or insufficient surface hardness, and have defects of low strength, which can no longer meet the needs of LCD TV development. Therefore, the development can simultaneously achieve ultra-thin, LCD TV materials with narrow sides, large screens, and spray-free effects are of great significance

preparation example Construction

[0037] The preparation method of fiber reinforced ABS material of the present invention comprises the following steps:

[0038] 1) Weigh the materials according to the ratio;

[0039] 2) Pour the materials except fibers into the mixing tank and stir for 5-10 minutes at a stirring speed of 300-450 rpm to mix the materials;

[0040] 3) Treat the glass fiber with a coupling agent and dry it:

[0041] 4) Put the mixed raw materials into the twin-screw extruder for melt extrusion and granulation. By increasing the side feed port, the fibers are added through the side feed port. The processing technology is as follows: the first zone of the twin-screw extruder 200- 210℃, 215-220℃ in the second zone, 215-220℃ in the third zone, 215-220℃ in the fourth zone, 220-230℃ in the fifth zone, 225-230℃ in the sixth zone, 220-225℃ in the seventh zone, 215-220 in the eighth zone ℃; screw speed 300-450 rpm.

Embodiment 1

[0043] Stir the weight ratio of ABS63.0%, toluene xylyl phosphate 10.0%, MPP3.0%, toughening agent HR1816.0%, lubricant 0.5%, antioxidant 1.0%, anti-ultraviolet agent 0.5% in the mixing tank After 5 minutes, the twin-screw extruder is melted and extruded to make granules, and the pre-treated glass fiber is added from the feeding port. Its processing technology is as follows: Twin-screw extruder one zone 200-210°C, two zone 215-220°C, three zone 215-220°C, fourth zone 215-220°C, five zone 220-230°C, six zone 225-230°C ℃, seven zone 220-225 ℃, eight zone 215-220 ℃; screw speed 300-450 rpm. Combining RHCM injection molding process to realize 50-inch ultra-thin, ultra-light, narrow-edge LCD TV frame, the production of products achieves reflective effect, no deformation and warping, surface hardness reaches H, and flame retardancy reaches UL94V0.

Embodiment 2

[0046] Stir the weight ratio of ABS63.0%, toluene xylyl phosphate 10.0%, MPP3.0%, toughening agent HR1816.0%, lubricant 0.5%, antioxidant 1.0%, anti-ultraviolet agent 0.5% in the mixing tank After 5 minutes, the twin-screw extruder is melted and extruded to make granules, and the pre-treated glass fiber is added from the feeding port. The processing technology is as follows: Zone 1 200-210℃, zone 2 215-220℃, zone 3 215-220℃, zone 4 215-220℃, zone 5 220-230℃, zone 6 225-230℃, zone 7 220 -225°C, eight zones 215-220°C; screw speed 300-450 rpm. Combining RHCM injection molding process to realize 50-inch ultra-thin, ultra-light, narrow-edge LCD TV frame, the production of products achieves reflective effect, without any deformation and warping, and the surface hardness reaches 2H.

Abstract

The invention discloses a fiber-reinforced ABS material and a preparation method thereof. The fiber-reinforced ABS material comprises, by weight percentage, 49.5-76.5.0% of ABS resin, 5.0-12.0% of phosphorus based flame retardant, 5.0-8.0% of nitrogen flame retardant, 3.0-8.0% of flexibilizer, 0.3-0.5% of lubricant, 0.1-1.0% of antioxygen, 0.1-1.0% of ultravioresistant agents, and 10-20% of inorganic fibers. The ABS material can produce appearance products having light reflection effects, highlight spraying-free and highlight imitation metal effects, and has the advantages that strength is high, warping is low, dimension stability is good, the appearance and color both reach the imitation metal effects, more choices are provided for industrial design, and therefore more characteristic consumption requirements are met. According to the ABS material of the structure, metal materials are not needed to play a role in strengthening, spraying, oil injection, electroplating and other deep processing methods are not needed, cost can be saved, energy consumption is reduced, pollution is reduced, and lightweight and ultra-thinness of the products are achieved.

Description

[technical field] [0001] The invention relates to the technical field of polymer materials, in particular to a fiber-reinforced ABS material and a preparation method thereof. [Background technique] [0002] Many LCD TV manufacturers are constantly pursuing the "green environmental protection" of their products. Among them, the TV casing made of high-gloss spray-free "black and bright" resin has a black and bright appearance, noble and elegant, stable and magnificent. The characteristic of this material is that injection molding products do not need to be sprayed, which not only improves production efficiency, saves labor and reduces production costs, but also reduces solvent volatilization, so it is more environmentally friendly. Not only that, but the large frame has also become the object of "cutting" in recent years. In recent years, narrow bezels have become the dominant trend of LCD TVs. At present, these narrow bezel LCD TVs are very fashionable and beautiful for hom...
