Embodiment 1
[0040] Use 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 of 600, and 10 parts of petroleum ether with a mass percentage 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 organobentonite, stirred for 2 hours, took out and evenly coated on the base film with a thickness of about 1 cm, passed nitrogen, and used ultraviolet light. Irradiate under light for 2 minutes, take out, wash with water, and dry to obtain a degradable discoloration material for simulated plants. The surface is then plastic-sealed with a layer of PET transparent film, which is cut into leaves of simulated plants.
[0041] The preparation method of described alkenyl lignin is:
[0042] Dissolve 20 g of lignin acetate in 100 g of sodium hydroxide solution with a co...
Embodiment 2
[0045] At room temperature (25°C), 12g of dimercaptosuccinic acid, 35g of mercaptopolyethylene glycol polylactic acid, molecular weight of 200, 100g of alkenyl lignin, 350g of ethanol, 3g of photoinitiator α, α-diol were mixed with a high-speed mixer at room temperature. Methoxy-α-phenylacetophenone, stir for 2h, the speed is 4000r / min, then add 12g V0 flame retardant organobentonite, stir for 2h, take it out and evenly coat it on the straw paper with a thickness of about 3cm, pass nitrogen, and use It was irradiated under ultraviolet light for 20 minutes, and the actinic radiation intensity was 20 mW / square centimeter. After taking it out, it was washed with water and dried to obtain a degradable and discolored material for simulated plants. blade. A preparation method of degradable discoloration material for simulated plants, which is characterized by comprising the following steps:
[0046] A high-speed mixer was used to mix 12 parts of dimercaptosuccinic acid, 35 parts of...
Embodiment 3
[0051] At room temperature (25°C), 14g of dimercaptosuccinic acid, 40g of mercaptopolyethylene glycol polylactic acid, 2000 molecular weight, 110g of alkenyl lignin, 350g of ethanol, 3.5g of photoinitiator 2-hydroxyl- 2-Methyl-1-phenyl-1-acetone, stir for 3h, the speed is 4000r / min, then add 14g V0 flame retardant organobentonite, stir for 3h, take out and evenly coat on the straw paper, the thickness is about 3cm, pass nitrogen , irradiated with ultraviolet light for 20 minutes, the actinic radiation intensity is 30 mW / square centimeter, taken out, washed with water, and dried to obtain a degradable discoloration material for simulated plants. The surface is then plastic-sealed with a layer of PET transparent film. leaves of plants.
[0052] A preparation method of degradable discoloration material for simulated plants, which is characterized by comprising the following steps:
[0053] Using a high-speed mixer, 16 parts of dimercaptosuccinic acid, 40 parts of mercaptopolyeth...
