Problems solved by technology

However, after adding a large amount of titanium dioxide, other physical properties of the produced polycarbonate, such as tensile strength, flexural modulus, and notched impact strength, are correspondingly reduced a lot, and in severe cases, it cannot even meet the requirements of LED lighting products, and Its shading effect is not ideal
When LED lamps require other properties such as flame retardancy, other raw materials such as flame retardants need to be added to polycarbonate raw materials, and the addition of other raw materials such as flame retardants will further aggravate the deterioration of this adverse effect

Abstract

The invention belongs to the technical field of LED (light-emitting diode) lamp manufacturing, and relates to a polycarbonate plastic master batch for an LED lamp as well as a preparation method and a use method of the polycarbonate plastic master batch. 45 to 50 parts of titanium dioxide; 5-6 parts of color powder; 5 to 15 parts of a toughening agent; 1 to 1.2 parts of an antioxidant; and 1-1.5 parts of a dispersant. The invention also provides a preparation method of the polycarbonate plastic master batch for the LED lamp and a use method of the polycarbonate plastic master batch for the LED lamp. According to the polycarbonate plastic master batch for the lamp as well as the preparation method and the use method of the polycarbonate plastic master batch, provided by the invention, more uniform color mixing, better shading effect and better physical properties can be obtained.

Description

Technical field [0001] The present invention belongs to the technical field of LED lamp manufacturing, relates to a polycarbonate plastic masterbatch for LED lamps and lanterns and preparation and use method thereof. Background [0002] At present, polycarbonate (PC) is widely used in the materials used to make LED lamps. In order to obtain better shading performance, a large amount of titanium dioxide needs to be added to the polycarbonate raw material. However, after the addition of a large amount of titanium dioxide, the other physical properties of the polycarbonate produced, such as tensile strength, bending modulus, and notched impact strength, have been correspondingly reduced a lot, and the serious ones cannot even meet the requirements of LED lamps and lanterns, and its shading effect is not ideal. When LED lamps and lanterns need other properties such as flame retardant properties, it is also necessary to add other raw materials such as flame retardants to polycarbonat...
