Embodiment 1-8
[0033] Embodiments 1-8 provide a method for preparing a hydrophobic antibacterial agent for corrugated cardboard, and a method for preparing a hydrophobic and antibacterial enhanced corrugated cardboard (E-type corrugated cardboard) using the hydrophobic and antibacterial agent.
[0034] Each component and consumption (mass percentage) of the hydrophobic antibacterial agent for corrugated cardboard of embodiment 1-8 are shown in Table 1 below, and the preparation steps are as follows:
[0035] (1) Preparation of gas-phase nano-silica: Add TEOS (Si(OC) dropwise to the mixed solution of alcohol (ethanol), water and ammonia 2 h 5 ) 4 ), stirred evenly at a constant temperature of 30° C. to obtain a reaction liquid, which was kept reacting at this temperature for 5 hours, and then washed, separated, and dried in sequence to obtain gas-phase nano-silica; set aside. The initial concentrations of the components in the reaction liquid are: 0.2 mol / L for TEOS, 10 mol / L for alcohol, a...

Abstract
The invention relates to the technical field of corrugated boards, in particular to a hydrophobic antibacterial agent used for a corrugated board, a hydrophobic antibacterial reinforced corrugated board applying the hydrophobic antibacterial agent and a preparation method thereof. The hydrophobic antibacterial agent takes fumed silica as a carrier, a silane coupling agent and nano silver ions are loaded, hydrophobic and antibacterial dual effect is compounded, and hydrophobic and antibacterial properties are excellent. The corrugated board coated with the hydrophobic and antibacterial agent has the advantages that the strength of the corrugated board is effectively enhanced, the corrugated board also has an antibacterial and hydrophobic dual function, the problem of moisture deterioration in a food transportation process can be effectively reduced, freshness of food is improved and a quality guarantee period of the food is prolonged, and the waste of the food is reduced. A multilayer spraying method that doubles sides of core paper and a paperboard are coated with the hydrophobic and antibacterial agent respectively is adopted, and the corrugated board has better hydrophobic and antibacterial effects.
Description
technical field [0001] The invention relates to the technical field of corrugated paper, in particular to a hydrophobic antibacterial agent for corrugated cardboard, a hydrophobic antibacterial reinforced corrugated cardboard using the hydrophobic antibacterial agent, and a method for preparing the hydrophobic antibacterial agent and the hydrophobic antibacterial reinforced corrugated cardboard. Background technique [0002] During the packaging and transportation of food, the packaging box is often affected by moisture due to changes in the external weather environment. After the packaging box is damp, the most significant harm is to provide a beneficial environment for the growth of bacteria. Every year, a large amount of food is spoiled and wasted due to problems in transportation, resulting in a serious waste of resources and endangering the natural environment. After corrugated paper absorbs water and gets wet, its strength will also decrease, and even cause damage to t...
