Abstract

The invention discloses a preparation method of a modified ABS material, a manufacturing method of a display terminal cambered rear shell and the display terminal cambered rear shell. The preparation method of the modified ABS material comprises the steps that a common ABS material, talcum powder, lubricating agents and an antioxidant are added into a plastic extruder, wherein the lubricating agents comprise the silicon-magnesium composite lubricating agent and the stearic acid lubricating agent, the antioxidant comprises the phosphorus phenolic composite antioxidant, and the modified ABS material is prepared from, by weight, 96%-98% of the common ABS material, 1%-2% of the talcum powder, 0.5%-2% of the silicon-magnesium composite lubricating agent, 0.2%-1% of the stearic acid lubricating agent and 0.3%-1% of the phosphorus phenolic composite antioxidant; the temperature of the plastic extruder is adjusted to 180 DEG C-230 DEG C, and the modified ABS material is extruded. Accordingly, the heat resistance and the strength of the modified ABS material are improved, and the size shrinkage rate of the modified ABS material is decreased.

Description

technical field [0001] The invention relates to the technical field of composite materials, and in particular to a method for manufacturing a modified ABS material, a method for manufacturing a curved rear case of a display terminal, and a curved rear case for a display terminal. Background technique [0002] With the development of science and technology, the product form of LCD TV is also constantly changing. From the initial small-size product form, it gradually develops towards the trend of ultra-narrow bezel, ultra-thin overall machine thickness, and super-large screen size. Moreover, LCD TV Gradually develop from the plane category to the curved surface category. Due to the shape of the product, curved TVs have higher requirements for the material of the rear shell. PC (Polycarbonate, polycarbonate) + ABS (Acrylonitrile-Butadiene-Styrene, acrylonitrile-butadiene-styrene plastic) is generally used for flame retardancy. Materials, but modified ABS materials are generall...
