Embodiment 1

[0019] Step (1): In parts by mass, 17 parts of semi-refined paraffin, 3 parts of polyvinyl butyral, 3 parts of stearic acid, and 16 parts of semi-refined paraffin were placed in a constant temperature water bath and heated to 95°C, 100r / min Stir for 20min, mix the raw materials;

[0020] Step (2): Add 2 parts of additive Awe-2, stir and mix, continue heating to 120°C, 100r / min constant temperature stirring for 20min;

[0021] Step (3): Continue heating to 140°C, stirring at 100r / min for 10min at constant temperature;

[0022] Step (4): Pour the obtained product into a forming tray, and cool to obtain an anti-mildew wax for outer packaging of corrugated boxes.

[0023] According to the GB73636-87 standard to test the content of fused-ring aromatics, the content of fused-ring aromatics in the anti-mildew wax obtained by the present invention reaches the standard and does not exceed the limit value.

Embodiment 2

[0025] Step (1): In parts by mass, 15 parts of semi-refined paraffin, 4 parts of polyvinyl butyral, 5 parts of stearic acid, and 20 parts of semi-refined paraffin were placed in a constant temperature water bath and heated to 90°C, 150r / min stirring for 30min, mixing the raw materials;

[0026] Step (2): Add 3 parts of additive Awe-2, stir and mix, continue to heat to 110°C, 150r / min constant temperature stirring for 10min;

[0027] Step (3): Continue heating to 130°C, stirring at 150r / min for 20min at constant temperature;

[0028] Step (4): Pour the obtained product into a forming tray, and cool to obtain an anti-mildew wax for outer packaging of corrugated boxes.

Embodiment 3

[0030] Step (1): In parts by mass, 19 parts of semi-refined paraffin, 3 parts of polyvinyl butyral, 5 parts of stearic acid, and 18 parts of semi-refined paraffin were respectively placed in a constant temperature water bath and heated to 100 ° C, 150 r / min Stirring for 15min, mixing the raw materials;

[0031] Step (2): Add 1 part of additive Awe-2, stir and mix, continue heating to 120°C, 150r / min constant temperature stirring for 15min;

[0032] Step (3): Continue heating to 120°C, stirring at 150r / min for 20min at constant temperature;

[0033] Step (4): Pour the obtained product into a forming tray, and cool to obtain an anti-mildew wax for outer packaging of corrugated boxes.

[0034] The anti-mildew wax prepared by the invention has good anti-mildew effect, can be stored and transported for a long time, and is not prone to adhesion, does not contain toxic substances, and is non-corrosive. The content of fused-ring aromatics is tested according to the GB73636-87 standa...

Abstract

The invention discloses mildew-proof wax for outer packing of a corrugated carton and a preparation method of the mildew-proof wax, and the mildew-proof wax is prepared from the following components in parts by mass: 15-19 parts of semi-refined paraffin, 2-5 parts of polyvinyl butyral, 2-5 parts of stearic acid, 15-20 parts of semi-refined paraffin and 1-4 parts of an additive Awe-2. The prepared mildew-proof wax is good in mildew-proof effect, capable of being stored and transported for a long time, not prone to adhesion, free of toxic substances and free of corrosion.

Description

technical field [0001] The invention relates to the technical field of waxes for outer packaging of corrugated boxes, in particular to an anti-mildew wax for outer packaging of corrugated boxes and a preparation method thereof. Background technique [0002] Paraffin wax, also known as crystalline wax, is one of the important chemical raw materials, with a carbon number of about 18-30. It is mainly used as components and packaging materials of food, oral medicine and certain commodities (such as wax paper, crayons, candles, carbon paper). [0003] Corrugated boxes are susceptible to moisture and mildew, which limits their application. The development of anti-mold treatment technology for corrugated boxes is very necessary. The main treatment methods include coating treatment, dipping treatment, etc. At present, simple moisture-proof agents are not ideal for anti-mildew effect, and the cost is high, and the additives are not environmentally friendly, contain toxic substances, ...
