preparation example Construction

[0018] A method for preparing a waterproof and antifreeze impregnating liquid for corrugated paper boxes. The preparation method comprises the following steps: mixing and stirring each raw material according to a required ratio at 100-110° C. for 3-5 minutes.

[0019] A method for using a waterproof and antifreeze impregnation solution for corrugated cardboard boxes, the method of use is as follows: first place a corrugated cardboard in the soaking solution at 100-110° C. Dry at 110-130°C, and finally cool at room temperature for more than 20 minutes.

[0020] Principle of the present invention is described as follows:

[0021] The present invention proposes an impregnation solution for corrugated boxes, which can directly form a strong chemical bond with the corrugated box, and quickly solidify on the surface of the corrugated box to form a firm reinforced protective layer, so that even if the corrugated box is placed in low temperature for a long time Its strength will not ...

Abstract

The invention relates to waterproof anti-freezing impregnating liquid for corrugated paper boxes. The waterproof anti-freezing impregnating liquid is prepared from the following raw materials and components in parts by weight: 50 to 70 parts of impregnating solution, 10 to 15 parts of EPDM (ethylene propylene diene monomer), 10 to 15 parts of EVA copolymer (ethylene-vinyl acetate), 3 to 5 parts of thermoplastic acrylic resin, 0.5 to 0.8 part of coupling agent, 3 to 5 parts of nanometer titanium dioxide and 8 to 10 parts of jute short fibers. During preparation, the raw materials are mixed at the temperature of 100 to 110 DEG C. When the waterproof anti-freezing impregnating liquid is used, a corrugated paper board is firstly impregnated into the impregnating liquid, and then is heated and baked, and cooled in sequence. By adopting the design, the waterproof anti-freezing impregnating liquid has the advantages that the waterproof and low-temperature properties and mechanical strength of the corrugated paper box are improved, and the methods are simple and economic.

Description

technical field [0001] The invention belongs to the field of macromolecule materials, and in particular relates to a waterproof and antifreeze impregnating liquid for corrugated cartons and a preparation and use method thereof, which are suitable for improving the low-temperature performance and mechanical strength of corrugated cartons. Background technique [0002] At present, under the advocacy of the new concept of nutrition, with the general improvement of people's living standards, frozen food is generally favored, and the consumption is increasing. Frozen (hidden) food is convenient, fast, and hygienic. A popular item for years. At the same time, frozen food is easy to preserve, easy to store, long fresh-keeping period, rich in nutrition, and delicious in taste, making it deeply loved by consumers. Looking at the entire frozen food market, the consumption of dairy products, fruit juices, cold drinks, and meat has greatly increased. At present, the packaging and tran...
