Problems solved by technology

[0003] Among them, the adhesive is one of the indispensable components in the packaging. The adhesive is mainly used for bonding and sealing in the packaging, but the stickiness of the adhesive is easy to adhere to dust, bacteria and mold, especially in a humid environment. The attached bacteria and mold are more likely to breed and cultivate colonies, which will affect or even destroy the storage of food, and bring hidden dangers to people's health and safety

Embodiment 1

[0040] A waterproof and mildew-proof adhesive for food packaging, comprising the following raw materials in parts by weight: 120 parts of modified epoxy resin, 8 parts of curing agent, and 35 parts of deionized water;

[0041] Described curing agent is maleic anhydride;

[0042] The preparation method of the waterproof and mildew-proof adhesive is as follows: add the modified epoxy resin and curing agent into the reaction kettle, raise the temperature to 110°C while stirring, and carry out the curing reaction for 4 hours after stirring, and add deionized water for mixing after the reaction is completed. Dilute evenly to obtain a waterproof and mildew-proof adhesive.

Embodiment 2

[0044] A waterproof and mildew-proof adhesive for food packaging, comprising the following raw materials in parts by weight: 130 parts of modified epoxy resin, 10 parts of curing agent, and 45 parts of deionized water;

[0045] Described curing agent is maleic anhydride;

[0046] The preparation method of the waterproof and mildew-proof adhesive is as follows: add the modified epoxy resin and curing agent into the reaction kettle, raise the temperature to 120°C while stirring, and carry out the curing reaction for 5 hours while stirring, and add deionized water for mixing after the reaction is completed. Dilute evenly to obtain a waterproof and mildew-proof adhesive.

Embodiment 3

[0048] A waterproof and mildew-proof adhesive for food packaging, comprising the following raw materials in parts by weight: 122 parts of modified epoxy resin, 7 parts of curing agent, and 35 parts of deionized water;

[0049] Described curing agent is maleic anhydride;

[0050] The preparation method of the waterproof and mildew-proof adhesive is as follows: add the modified epoxy resin and curing agent into the reaction kettle, raise the temperature to 114°C while stirring, and carry out the curing reaction for 2 hours while stirring, and add deionized water for mixing after the reaction is completed.

Abstract

The invention discloses a waterproof mildew-resistant adhesive for food packaging and a preparation method thereof. The waterproof mildew-resistant adhesive comprises the following raw materials by weight: 120-130 parts of modified epoxy resin, 7-10 parts of a curing agent and 35-50 parts of deionized water. The antibacterial active group aminothiazole is introduced during the modification of epoxy resin, so the modified epoxy resin has good biological activity and good inhibition effect on bacteria, fungi, mold and acarids; since the active aminothiazole group is introduced into the epoxy resin in the form of a chemical bond, so good firmness is obtained, and the antibacterial and anti-mildew properties of the adhesive can be maintained for a long time; in addition, a thiazole derivativehas odor with distinct characteristics and a thiazole group has a low olfactory threshold and a pleasant smell, so the thiazole derivative is an indispensable ingredient in spices and food, can give out delicate fragrance and whet the appetite when applied to adhesives for outer packaging of food, and has good application prospects.

Description

technical field [0001] The invention belongs to the technical field of packaging, and in particular relates to a waterproof and mildew-proof adhesive for food packaging and a preparation method thereof. Background technique [0002] Food packaging is an integral part of food commodities. It protects food and prevents damage from biological, chemical, and physical external factors during the circulation of food from the factory to consumers. It can also maintain the stable quality of the food itself. The function of it is to facilitate the eating of food, and it is the first to express the appearance of food and attract the image of consumption, and it has value other than material cost. [0003] Among them, the adhesive is one of the indispensable components in the packaging. The adhesive is mainly used for bonding and sealing in the packaging, but the stickiness of the adhesive is easy to adhere to dust, bacteria and mold, especially in a humid environment. The attached ba...
