Embodiment 1
[0040] Using a high-speed mixer to mix 10 parts of dimercaptosuccinic acid, 30 parts of mercaptopolyethylene glycol polylactic acid, 100 parts of alkenyl lignin, molecular weight 600, 10 parts of petroleum ether with a mass percent content of 5% cholesteric liquid crystal Solution, 300 parts of polyacrylic acid emulsion, 2.5 parts of photoinitiator, stirred at 30°C for 2 hours, then added 2 parts of flame-retardant organic bentonite, stirred for 2 hours, took it out and evenly coated it on the base film, with a thickness of about 1cm, passed nitrogen, and used ultraviolet Irradiate under light for 2 minutes, take it out, wash it with water, and dry it to obtain a degradable color-changing material for simulating plants. The surface is then plastic-sealed with a layer of PET transparent film, and then cut into leaves of simulating plants.
[0041] The preparation method of described alkenyl lignin is:
[0042] Dissolve 20g of lignin acetate in 100g of 0.5mol / L sodium hydroxide ...
Embodiment 2
[0045] At room temperature (25° C.), use a high-speed mixer to mix 12 g of dimercaptosuccinic acid, 35 g of mercapto polyethylene glycol polylactic acid, molecular weight 200, 100 g of alkenyl lignin, 350 g of ethanol, and 3 g of photoinitiator α, α-di Methoxy-α-phenylacetophenone, stirred for 2 hours, and the speed was 4000r / min, then added 12g V0 flame-retardant organic bentonite, stirred for 2 hours, took it out and evenly coated it on straw paper, with a thickness of about 3cm. Irradiate under ultraviolet light for 20 minutes, the intensity of actinic radiation is 20 mW / cm2, take it out, wash it with water, and dry it to obtain a degradable color-changing material for simulating plants. The surface is then plastic-sealed with a layer of PET transparent film, which is cut into the shape of simulating plants. blade. A method for preparing a degradable color-changing material for simulated plants, characterized in that it comprises the following steps:
[0046] 12 parts of d...
Embodiment 3
[0051] At room temperature (25° C.) using a high-speed stirrer to mix 14 g of dimercaptosuccinic acid, 40 g of mercapto polyethylene glycol polylactic acid, molecular weight 2000, 110 g of alkenyl lignin, 350 g of ethanol, and 3.5 g of photoinitiator 2-hydroxyl- 2-Methyl-1-phenyl-1-propanone, stir for 3 hours, the speed is 4000r / min, then add 14g V0 flame-retardant organic bentonite, stir for 3 hours, take it out and spread it on the grass paper evenly, the thickness is about 3cm, and pass in nitrogen , irradiated with ultraviolet light for 20 minutes, and the intensity of actinic radiation is 30 mW / cm2. After taking it out, it is washed with water and dried to obtain a degradable color-changing material for simulated plants. The surface is then plastic-sealed with a layer of PET transparent film, which is cut into simulated The leaves of the plant.
