Embodiment 1

[0013] A preparation method of a disposable tableware degradable packaging material modifier, the modifier consists of the following components in parts by weight: 12 parts of calcium stearate, 4 parts of alginate, 2 parts of carboxymethyl cellulose, poly 3 parts of vinylpyrrolidone, 10 parts of glyceryl succinate, 12 parts of talcum powder, 12 parts of wollastonite, 5 parts of methylurea, 3 parts of carbohydrase, 4 parts of glutamic acid; Add calcium stearate, alginate, carboxymethyl cellulose, polyvinylpyrrolidone, glyceryl succinate, talcum powder, wollastonite, methylurea, carbohydrase and glutamine in sequence, each time a substance is added, Stir at low speed for 1 minute before adding the next substance. After all the addition is complete, raise the temperature to 87°C, stir at high speed for 13 minutes, then discharge the material, and pack it after cooling.

Embodiment 2

[0015] A preparation method of a disposable tableware degradable packaging material modifier, the modifier consists of the following components in parts by weight: 16 parts of calcium stearate, 2 parts of alginate, 4 parts of carboxymethyl cellulose, poly 1 part of vinylpyrrolidone, 12 parts of glyceryl succinate, 10 parts of talcum powder, 16 parts of wollastonite, 3 parts of methylurea, 5 parts of carbohydrase, and 2 parts of glutamic acid; Add calcium stearate, alginate, carboxymethyl cellulose, polyvinylpyrrolidone, glyceryl succinate, talcum powder, wollastonite, methylurea, carbohydrase and glutamine in sequence, each time a substance is added, Stir at low speed for 2 minutes before adding the next substance. After all the addition is complete, raise the temperature to 83°C, stir at high speed for 17 minutes, then discharge the material, and pack it after cooling.

Embodiment 3

[0017] A preparation method of a modifier for disposable tableware degradable packaging materials, the modifier is composed of the following components in parts by weight: 14 parts of calcium stearate, 3 parts of alginate, 3 parts of carboxymethyl cellulose, poly 2 parts of vinylpyrrolidone, 11 parts of glyceryl succinate, 11 parts of talcum powder, 14 parts of wollastonite, 4 parts of methylurea, 4 parts of carbohydrase, 3 parts of glutamic acid; Add calcium stearate, alginate, carboxymethyl cellulose, polyvinylpyrrolidone, glyceryl succinate, talcum powder, wollastonite, methylurea, carbohydrase and glutamine in sequence, each time a substance is added, Stir at a low speed for 1.5 minutes before adding the next substance. After all the addition is complete, raise the temperature to 85°C, stir at a high speed for 15 minutes, then discharge the material, and pack it after cooling.

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.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a preparation method of a disposable tableware degradable packaging material modifier. Background technique [0002] In order to solve the problem of plastic white pollution, people are looking for alternative completely degradable materials through various means. Starch and plant fiber, as natural polymer substances, are abundant and cheap, and are inexhaustible renewable resources. It has extensive research and application in the degradable materials of disposable tableware. However, when starch and fiber are used to produce starch-based fiber-reinforced biodegradable packaging materials, there are problems such as poor processability, brittle products, and poor water resistance. [0003] Regarding degradable materials, my country's research has also made some progress and obtained some patents. For starch-based materials, the starch modification of Changchun Ins...
