Abstract
The invention discloses a preparation method for a modifying agent for a disposable tableware degrading packaging material. The modifier consists of the following components in parts by weight: 12-16 parts of calcium stearate, 2-4 parts of phycocolloid, 2-4 parts of carboxymethylcellulose, 1-3 parts of polyvinylpyrrolidone, 10-12 parts of succinic acid glyceride, 10-12 parts of talcum powder, 12-16 parts of wollastonite, 3-5 parts of methyluren, 3-5 parts of carbohydrase and 2-4 parts of glutamic acid. The preparation method comprises the steps: sequentially adding the calcium stearate, the phycocolloid, the carboxymethylcellulose, the polyvinylpyrrolidone, the succinic acid glyceride, the talcum powder, the wollastonite, the methyluren, the carbohydrase and the glutamic acid into a high-speed stirrer, performing low-speed stirring for 1-2 minutes at each time of adding each substance, then adding another substance until all the substances are added, heating to 83-87 DEG C, performing high-speed stirring for 13-17 minutes, discharging, cooling the material, and packaging the material.
