Problems solved by technology

These factors are in the case of suitable ambient temperature, and various molds such as Aspergillus basilica grow naturally on the inner side of the wooden carton. Cross-infection and mildew will produce moldy acid odor, which will have a negative impact on the natural aging of tobacco leaves and cause huge economic losses to the tobacco industry

Embodiment 1

[0016] (1) purchase base paper (kraft paper); (2) take by weighing 40kg of o-phenylphenol, 20kg of benzoic acid, 15kg of propylparaben, and 30kg of sorbic acid, put into a reactor with a stirrer, add 300kg Ethanol, heated to 60°C at a heating rate of 1°C per minute and stirred. After completely dissolving, spray on one side of the kraft paper and dry in the greenhouse to obtain a semi-finished product. The antifungal agent attached to the kraft paper is 50g / m 2 (3) Weigh 140kg of high-speed cigarette adhesive, 24kg of propionic acid, 16kg of carbendazim, and 10kg of vitamin E, mix and stir evenly, and then coat the side of the semi-finished product with the antifungal agent, and the coating amount is 40-70g / m 2 , and then placed in the greenhouse to dry, sealed and packaged, that is the finished product.

[0017] The results of the antibacterial test of the composite mold-proof paper of this embodiment to various molds are shown in the following table:

Embodiment 2

[0022] (1) Take by weighing 15kg of o-phenylphenol, 15kg of benzoic acid, 10kg of propylparaben, and 20kg of sorbic acid, put them into a reactor with a stirrer, add 180kg of ethanol, stir at room temperature, and wait until completely dissolved , coated on one side of the kraft paper, and dried in the greenhouse to obtain a semi-finished product. The antifungal agent attached to the kraft paper is 30g / m 2 (3) Weigh 60kg of ordinary starch adhesive, 10kg of calcium propionate, 5kg of benomyl, and 10kg of vitamin C, mix and stir evenly, and spray on the side of the semi-finished product with antifungal agent, and the spraying amount is 40g / m 2 .

[0023] All the other are with embodiment 1.

[0024] The antibacterial and antifungal effects of the composite anti-mold paper in this embodiment are close to those of the composite anti-mold paper in Example 1.

Embodiment 3

[0026] (1) Weigh 10kg of o-phenylphenol, 15kg of benzoic acid, 5kg of propylparaben, and 10kg of sorbic acid, put them into a reactor with a stirrer, add 150kg of ethanol, stir at room temperature, and wait until completely dissolved , coated on one side of kraft paper, and dried in a greenhouse to obtain a semi-finished product. The antifungal agent attached to the kraft paper is 25g / m 2 (3) Take by weighing 50kg of ordinary starch adhesive, 10kg of sodium propionate, 8kg of carbendazim, and 8kg of vitamin C, mix and stir evenly, and spray on the side of the semi-finished product with antifungal agent, and the spraying amount is 35g / m 2 .

[0027] All the other are with embodiment 1.

[0028] The antibacterial and antifungal efficacy of the composite anti-mold paper of this embodiment is inferior to that of the composite anti-mold paper of Example 1.

Abstract

The invention discloses safe high efficiency complex type anti-fungicide paper and its manufacturing method. It is used the common kraft as base paper. One surface of the base paper is painted or spayed one layer complex type anti-fungus agent formed by o-phenyl phenyl phenol, benzoic acid, nipalgin propyl ester, and sorbic acid. The complex type anti-fungus agent layer is painted one layer complex type adhesion agent contained anti-fungus agent propionic acid, carbendazim, and vitamin E or C, and antioxidant complex type adhesion agent. The manufacturing method includes the following steps: selecting base paper; preparing and painting and spraying complex type anti-fungus; preparing and painting and spraying complex type adhesion agent. The anti-fungicide paper is no odor and peculiar smell, not influenced by environment, and no harm for people and animal. It can be applied to mould proofing of tobacco and its products, foods, forage, and so on.

Description

technical field [0001] The invention relates to a compound anti-mildew product and a preparation method thereof, in particular to a safe and efficient compound anti-mold paper and a preparation method thereof. Background technique [0002] At present, the tobacco leaves of tobacco enterprises are usually packaged in cartons or plywood after threshing and rebaking. There are three main anti-mildew measures for storing tobacco sheets: (1) controlling the moisture content of the stored tobacco sheets to be less than 13% and uniform. To this end, two aspects of work are required, ① storage of tobacco leaves and regular moisture content testing; ② improvement of storage conditions: the storage warehouse should have good sealing, moisture-proof and ventilation, and dehumidification facilities (usually using moisture-absorbing agents or dehumidifiers) dehumidification). (2) Timely control the temperature and humidity of the tobacco storage warehouse according to the detection sit...
