Abstract

The invention provides a glyphosine intercalated structural selective infrared absorbing material as well as a preparation method and an application thereof. The infrared absorbing material is abbreviated as GLYP-LDHs with molecular formula being (M<2+>)1-x(Al<3+>)x(OH)2(C4H9NO8P2<2->)a(B<n->)b*mH2O. The preparation method of the material is implemented by taking hydrotalcite as precursor and intercalating N, N-dual (phosphine hydroxymethyl) glycine ions into the hydrotalcite layers by ion exchange method to assemble to obtain GLYP-LDHs with good crystal phase structure. The GLYP-LDHs has good infrared absorbency. When applied to polymer films such as polyethylene or ethylene-acetic acid ethylene polymer and the like, GLYP-LDHs has better infrared absorbency effect than MgAl-CO3-LDHs, when MgAl-CO3-LDHs and GLYP-LDHs are mixed in proportion of 1:1 followed by adding PE, the infrared absorbency effect is much better than adding GLYP-LDHs alone.

Description

technical field [0001] The invention relates to a selective infrared absorption material and its preparation method and application, in particular to the selective infrared absorption material with glyphosate intercalation structure and its preparation method and application. Background technique [0002] Agricultural film is widely used in modern agricultural production and cultivation because of its good light transmission and heat preservation. In recent years, infrared absorbing materials, as important functional additives, have played an important role in improving the thermal insulation performance of agricultural films. The effective wavelength of crop photosynthesis is 0.4-0.7μm, which is basically consistent with visible light. Therefore, it is necessary to improve the permeability of the agricultural film in the wavelength range of 0.4-0.7 μm, which requires that the inorganic particles dispersed in the agricultural film have a small size (<0.4 μm). During the...
