Problems solved by technology

[0006] The disadvantage of the prior art is that the chromaticity of the polycarbonate sample after the flame-retardant modification turns yellow and the brightness decreases, and the PC particles themselves appear slightly yellow, which makes the overall color chromaticity of the product turn yellow and the brightness decreases. Transparency and gloss are also reduced, which limits its application

Embodiment 1-5

[0038] Example 1-5: A color-modified flame-retardant PET and PC composite material, prepared by the following steps, see Table 1 for its components and contents:

[0039] S0: Treatment of hollow glass microspheres: Dilute the silane coupling agent accounting for 1.5% of the total mass of the hollow glass microspheres with absolute ethanol in a water bath at 35-45° C. The mass ratio is 8:1. At 15-35°C, add the hollow glass microspheres weighed in proportion while stirring the diluent. After all the hollow glass microspheres are added, continue to stir for 5-10 minutes, and then add the hollow glass microspheres. 5% colorant of the total mass of beads, stirred for 2 hours, then dried at 80°C for more than 4 hours, and finally placed the dried powder in a closed container for later use; the silane coupling agent is γ-(2,3-epoxy Propoxy)propyltrimethoxysilane;

[0040] S1: Weigh each component according to the ratio in Table 1, wherein the hollow glass microspheres are the hollow...

Abstract

The invention discloses a color modified flame retardant PET (polyethylene terephthalate) and PC (polycarbonate) composite material and a preparation method thereof. The color modified flame retardant PET and PC composite material is prepared from the following raw materials in parts by weight: 45 to 70 parts of PC, 30 to 45 parts of PET, 5 to 15 parts of hollow glass microspheres, 0.5 to 1.0 part of flame retardants, 3 to 15 parts of toughening compatilizers, 0.5 to 1 part of antioxidizers, 0.2 to 1 part of lubricating agents and 0.1 to 0.2 part of coloring agents, wherein the color agents are one or several of anthraquinone organic transparent dyestuff and anthraquinone type organic transparent purple dyestuff. The good flame retardant effect is achieved; meanwhile, good color and transparency are realized.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a color-modified flame-retardant PET and PC composite material and a preparation method thereof. Background technique [0002] Polycarbonate (PC for short) is a general term for a class of polymer compounds containing carbonate in the molecular chain, among which bisphenol A polycarbonate is the polycarbonate with the largest output and the widest application. Bisphenol A polycarbonate not only has excellent impact strength, creep resistance, heat resistance, cold resistance and good transparency, but also has high tensile strength, flexural strength, elongation and rigidity , excellent aging resistance, electrical properties, low water absorption, but poor oil resistance, wear resistance and processing performance. [0003] Polyethylene terephthalate (polyethyleneterephthalate) is referred to as PET, which belongs to thermoplastic polyester. It has good thermal stabil...
