Embodiment 1

[0037] Weigh 0.25g of CdO and add it into a 50ml three-neck flask. Then weigh 2.5ml of oleic acid and 2.5ml of octadecene solvent with a graduated cylinder and place them in a three-necked flask. Place the three-necked flask on a constant temperature magnetic stirrer to ensure that it is under N 2 The temperature was raised to 250°C at a constant rate under ambient conditions. The solution in the flask became clear and yellowish. The temperature was lowered to room temperature, and it was reserved for the next experiment.

[0038] Take 0.04g of Se powder with a weighing balance, accurately pipette 0.5ml and place it in a test tube. The mixture was ultrasonically dissolved in a sonicator, and the solution in the test tube became clear, which was reserved for the next experiment.

[0039] Mix 0.3ml of tri-n-octylphosphorus solution, 0.2ml of the solution obtained in step a and 5ml of oleylamine in a 50ml three-necked flask, and place the reaction system under N 2 The temper...

Abstract

The invention relates to a nano composite material for absorbing near-infrared light. The nano composite material comprises the following substances in parts by weight: 60-80 parts of transparent resin, 5-10 parts of a compatilizer, 2-5 parts of a flexibilizer, 0.3-0.6 part of an antioxidant, 0.5-1.0 part of a lubricant, 0.5-1.0 part of a weather-resistant agent and 5-15 parts of a near-infrared absorbent. The invention provides a nano material capable of absorbing near-infrared light and a preparation method of a composite material of the nano material, the composite material takes resin as a matrix, a nano near-infrared absorbent is added at the same time, and the light performance of the resin is improved through the near-infrared absorbent by utilizing the infrared light absorption performance (capable of reducing the transmittance of halogen light wavelength) of the infrared absorbent; a sample piece can be obtained by adopting a resin processing technology; the prepared sample piece can well absorb light within the range of 500-1000 nm, and can be used for filtering materials, optical filters, imitation detection materials and the like; and meanwhile, the physical properties of the resin are combined, the light filter for absorbing near-infrared light is provided, the defect that the material reflects infrared light is overcome, the effect is remarkable, and the application prospect is good.

Description

technical field [0001] The invention belongs to the field of macromolecule materials, in particular to a composite material that absorbs near-infrared light in nanometers. Background technique [0002] Near-infrared absorbers are substances that absorb near-infrared light. At present, with the wide application of green building energy-saving, automotive glass heat insulation and solar film heat insulation markets, more and more near-infrared absorbers for different purposes have been obtained. Promote widely. Among them, the composite near-infrared absorber of organic functional materials and nano-complexes has become a research hotspot. [0003] Due to its special nanometer size, we need to determine its composition and crystal structure according to complexes with different chemical compositions and spatial structures. [0004] This product is a raw material added liquid, which is a nanometer high-efficiency infrared absorption material. It can be added to various coatin...
