Example Embodiment
[0012] Example one
[0013] A method for preparing a modifier of a disposable tableware degradable packaging material, the modifier is composed of the following components in parts by weight: 12 parts of calcium stearate, 4 parts of algin, 2 parts of carboxymethyl cellulose, poly 3 parts of vinylpyrrolidone, 10 parts of glycerol succinate, 12 parts of talc, 12 parts of wollastonite, 5 parts of methylurea, 3 parts of carbohydrase, 4 parts of glutamic acid; the preparation method is: in a high-speed mixer Calcium stearate, algin, carboxymethyl cellulose, polyvinylpyrrolidone, glyceryl succinate, talc, wollastonite, methyl urea, carbohydrase and glutamine are added in sequence, and each substance is added. Stir at low speed for 1 minute before adding the next substance. After all the additions are completed, heat up to 87°C, stir at high speed for 13 minutes, then discharge the material, and pack after cooling.
Example Embodiment
[0014] Example two
[0015] A method for preparing a modifier of degradable packaging materials for disposable tableware. The modifier is composed of the following components in parts by weight: 16 parts of calcium stearate, 2 parts of algin, 4 parts of carboxymethyl cellulose, poly 1 part of vinylpyrrolidone, 12 parts of glyceryl succinate, 10 parts of talc, 16 parts of wollastonite, 3 parts of methyl urea, 5 parts of carbohydrase, 2 parts of glutamic acid; the preparation method is: in a high-speed mixer Calcium stearate, algin, carboxymethyl cellulose, polyvinylpyrrolidone, glyceryl succinate, talc, wollastonite, methyl urea, carbohydrase and glutamine are added in sequence, and each substance is added. Stir at low speed for 2 minutes before adding the next substance. After all the additions are completed, heat up to 83°C, stir at high speed for 17 minutes, then discharge the material, and pack after cooling.
Example Embodiment
[0016] Example three
[0017] A preparation method of a modifier for a disposable tableware degradable packaging material, the modifier is composed of the following components in parts by weight: 14 parts of calcium stearate, 3 parts of algin, 3 parts of carboxymethyl cellulose, poly 2 parts of vinylpyrrolidone, 11 parts of glyceryl succinate, 11 parts of talc, 14 parts of wollastonite, 4 parts of methylurea, 4 parts of carbohydrase, 3 parts of glutamic acid; the preparation method is: in a high-speed mixer Calcium stearate, algin, carboxymethyl cellulose, polyvinylpyrrolidone, glyceryl succinate, talc, wollastonite, methyl urea, carbohydrase and glutamine are added in sequence, and each substance is added. Stir at low speed for 1.5 minutes before adding the next substance. After all the additions are completed, heat up to 85°C, stir at high speed for 15 minutes, then discharge the material, and pack after cooling.
