Abstract

The invention discloses a high-heat-insulation, ultraviolet-isolation and transparent colored master batch which comprises the following components in percentage by weight: 50-70% of resin, 0.5-10% of dispersing agent, 2-10% of heat-insulation ultraviolet-isolation nano material, 10-30% of slipping agent and 0-10% of coloring agent. The invention further discloses a preparation method of the high-heat-insulation, ultraviolet-isolation and transparent colored master batch. According to the master batch and the preparation method, the master batch and a transparent polyester chip are matched at a ratio, and subjected to extrusion and two-way stretch to produce a high-heat-insulation, ultraviolet-isolation and transparent colored film; the high-heat-insulation, ultraviolet-isolation and transparent colored film has excellent heat-insulation and ultraviolet-isolation functions; the heat-insulation and ultraviolet-isolation capacity can be adjusted as required; the color is uniform and consistent; and when the master batch is applied to PET (polyethylene glycol terephthalate) film extrusion or sheet extrusion, the master batch is smog-free, high in transparency and good in smooth effect.

Description

technical field [0001] The invention relates to the field of macromolecule materials, in particular to a transparent colored masterbatch with high heat and ultraviolet resistance and a preparation method thereof. Background technique [0002] With the global warming and the increasing tension of energy and the extensive application of glass in construction vehicles, functional protective films such as heat insulation, UV protection, explosion-proof, and energy-saving protective films are becoming more and more important. The energy of sunlight is composed of 53% infrared rays, 44% visible light and 3% ultraviolet energy. The heat insulation and UV insulation film mainly reflects and absorbs the infrared and ultraviolet rays in sunlight and varies according to the transmittance of visible light. Block solar energy accordingly. [0003] With the development of technology, various technologies have been formed to achieve the above goals, such as: [0004] The publication numb...
