Problems solved by technology

[0002] With the continuous development of science and technology and the continuous improvement of people's living standards, paper has been endowed with multiple uses. Cartons made of cardboard have many advantages such as convenient use, simple production and low price, but there is a very big disadvantage, that It is not waterproof. In rainy or humid weather, the carton is very easy to get wet and reduce its mechanical properties, or even rot.
It is easy to cause excessive consumption of raw materials and waste energy

Abstract

The invention discloses a paperboard waterproofing agent and a preparation method thereof and relates to the technical field of paper waterproofing. The paperboard waterproofing agent comprises a paraffin microemulsion, dimethyl silicone oil, waterborne polyurethane, acrylic acid, butyl acrylate, calcium hydroxide, oligolactic acid, chamomile, polyoxyethylene oleate, ammonium persulfate, isopropanol, ethyl acetate, xylene, ammonium hydroxide, an emulsifier, a dispersant and deionized water. In use, the paperboard waterproofing agent is diluted by water of which the use amount is 5 to 10 times that of the paperboard waterproofing agent, and a paper to be subjected to waterproof and moistureproof treatment is coated mechanically and is dried at a high temperature so that scattered water-caused destruction of box strength is reduced, the box is effectively protected and good water prevention effects are obtained. The preparation method has simple processes. The paperboard waterproofing agent prolongs a carton service life, reduces material consumption and has energy saving and environmental protection effects.

Description

technical field [0001] The invention relates to the technical field of paper waterproofing, in particular to a cardboard waterproofing agent and a preparation method thereof. Background technique [0002] With the continuous development of science and technology and the continuous improvement of people's living standards, paper has been endowed with multiple uses. Cartons made of cardboard have many advantages such as convenient use, simple production and low price, but there is a very big disadvantage, that It is not waterproof. In rainy or humid weather, the carton is very easy to get wet and reduce its mechanical properties, or even rot. It is easy to cause excessive consumption of raw materials and waste of energy. Therefore, improving the waterproof performance of cartons is of great significance for improving the overall performance of cartons, expanding the application range and prolonging the service life. Therefore, the development of a waterproof treatment agent w...
