Problems solved by technology

[0004] The problem solved by the present invention is to provide a preparation method of anti-virus wrapping paper, which solves the problem that ASC-28-6 is only added to the product as an additional product, and cannot guarantee protection and isolation of viruses at the same time in other production links; At the same time, during the processing of wrapping paper, it needs to be cut into uniform size specifications. When the existing cutting device is cutting, it is easy to cause the movement of the wrapping paper, which will lead to deviations in the cut specifications, resulting in wasteful technical problems

Embodiment 1

[0026] see Figure 1~Figure 4 , a preparation method of antiviral wrapping paper, the concrete operation steps of this preparation method are as follows:

[0027] Step 1: Put wood pulp, hardwood pulp and kaolin through disc grinding and beating, add dilution water, wet strength agent, retention aid and pulp sizing agent to the pulp, and remove the pulp from the pulp through a slag remover and a pressure screen After being diluted with water by the frequency conversion pulp pump for the second time, it is sent to the paper headbox to distribute the pulp evenly and then go online. It is formed and dehydrated in the box and vacuum couch roll, and then dehydrated by pressing, and the packaging base paper is obtained after being contacted and dried by the steam dryer;

[0028] Step 2: The packaging base paper is transported to the sizing equipment for surface sizing. The sizing agent is made of corn starch glue and Ankevit concentrate according to the scientific formula. The main ...

Embodiment approach

[0033] As an embodiment of the present invention, the flattening mechanism 3 includes a U-shaped seat 23, a cylinder body 24, a second spring 25, a movable rod 26, a roller seat 27 and a pressure roller 28, and a cylinder is installed through the top side of the U-shaped seat 23. body 24, a second spring 25 is installed inside the cylinder body 24, the second spring 25 is connected to the bottom end of the movable rod 26, and the bottom end of the movable rod 26 is located below the cylinder body 24 and a roller seat 27 is installed, and the bottom side of the roller seat 27 is installed horizontally There are several pressure rollers 28, and the second spring 25 in the cylinder body 24 of the flattening mechanism 3 stretches and drives the movable rod 26 and the roller seat 27 to move, and then presses the flattened and dried preliminary paper on the transmission belt 5 through the pressure rollers 28 , which plays a limiting role in the preliminary paper movement, avoiding th...

Embodiment 2

[0038] A preparation method of antiviral wrapping paper, the specific operation steps of the preparation method are as follows: pass the hydrotalcite through a 40-mesh sieve, and add the hydrotalcite to the long carbon chain anionic surfactant dodecane with a concentration of 0.5mol / L In the sodium dodecyl sulfonate solution, the volume of sodium dodecyl sulfonate solution corresponding to each gram of hydrotalcite is 2mL, stirred in a water bath at 50°C for 2h; then add the short carbon chain anionic surfactant sodium butyrate, Add 0.2mmol short carbon chain anionic surfactant, then stir in 50°C water bath for 2h, filter the product, wash with distilled water, filter dry, dry at 90°C, and activate at 105°C for 30min; grind, pass 50 mesh sieves, obtained the organic hydrotalcite prepared by double anionic surfactant modification;

[0039] Add the prepared dianion surfactant-modified hydrotalcite into 25mg / L nitrobenzene, the solid-liquid (mass) ratio is 1:2000, stir for 2h, le...

Abstract

The invention relates to a preparation method of antiviral packaging paper. The method comprises the following specific operation steps: pulping wood pulp, hardwood pulp and kaolin through a disc mill, adding dilution water, a wet strength agent, a retention aid and an internal sizing agent into the pulp, removing air and impurities in the pulp through a slag separator and a pressurized screen, after secondary dilution by adding water through a variable-frequency slushing pump, conveying the pulp to a paper flow box for uniform pulp distribution, putting the pulp on a net, forming and dehydrating the pulp at a forming plate, a gravity dehydration plate, a low-vacuum water suction box, a high-vacuum water suction box, a vacuum couch roll and the like of a net part, then preparing the packaging base paper after squeezing dehydration and contact drying in a steam drying cylinder, and fusing ASC-28-6 is directly in the processing process of the raw materials, so that the product has an anti-virus effect. The packaging paper provided by the invention can be used as a main carrier for packaging and transportation to directly play a role in adsorbing and inactivating viruses in the production and transportation processes, so that the transmission possibility of the viruses in the logistics transportation process is reduced.

Description

technical field [0001] The invention relates to the technical field of wrapping paper processing, in particular to a preparation method of antiviral wrapping paper. Background technique [0002] Wrapping paper refers to the paper used for packaging, which has high strength, low moisture content, low air permeability, no corrosion, certain water resistance and is beautiful to use; paper used for food packaging also requires hygiene, sterility, and non-toxicity. Contamination impurities, etc. [0003] The ASC-28-6 nanomaterial developed by the Chinese Academy of Sciences has the effect of adsorbing and inactivating coronaviruses and adenoviruses. It has been applied to medical equipment and virus protection related products. The current main application method of related products is to use nano-functional materials Built into the product, it plays the role of adsorption and purification in a ventilated environment, but it does not have anti-virus effects. For example, a layer...
