A kind of dipping liquid and the transparent paper prepared by it and the method for rapidly preparing transparent paper

Abstract

The invention discloses impregnation liquid and transparent paper sheets prepared from the impregnation liquid as well as a method for rapidly preparing the transparent paper sheets. The impregnation liquid disclosed by the invention is prepared from a transparent agent, a surfactant, a water-resisting agent and a lubricant. The method for rapidly preparing the transparent paper sheets comprises the following steps: putting raw paper into the impregnation liquid and impregnating; taking out the raw paper and fitting the impregnated paper sheets between two pieces of thin film materials; extruding extra surplus impregnation liquid by utilizing an extruding device; then separating the impregnated paper sheets from the thin film materials; after drying the impregnated paper sheets, carrying out calendering treatment to obtain the transparent paper sheets. The impregnation liquid disclosed by the invention has the advantages of simple raw materials, abundant sources and easy preparation; the preparation method disclosed by the invention has the advantages of simple and convenient operation process and easy industrialized production; the paper sheets prepared by the method have good transparency and also has excellent tensile strength, bursting strength, barrier property and water-resisting property.

Description

technical field

[0001] The invention belongs to the technical field of transparent paper, and in particular relates to an impregnating liquid, a transparent paper prepared by the same and a method for rapidly preparing the transparent paper. Background technique

[0002] Transparent paper is a kind of special paper with excellent transparency. Common imitation parchment paper, cellophane, tracing paper and glassine paper in the market are all transparent papers. As an emerging high-performance transparent substrate, transparent paper has the advantages of low-carbon environmental protection, curlability, high processing temperature, and good printability. Due to the advantages of sustainable development, easy availability of raw materials and convenient papermaking, biocompatibility and degradability, favorable roll-to-roll printing production, excellent optics, mechanics and barrier properties, etc., it has been widely used in food packaging, maps, plastics, etc. Peel off ...

Embodiment 1

[0042] A kind of preparation of transparent paper, the steps are as follows:

[0043] The basis paper adopts a basis weight of 25 g / m 2 Wrapping paper with a tightness of 0.5 g / cm 3 , the scanning electron microscope image of the base paper is shown in figure 1 shown by figure 1 It can be seen that the base paper fibers are intertwined with each other and have many pores.

[0044] Impregnation solution: 500 g of transparent agent, 1.5 g of surfactant, 2.5 g of water-resistant agent and 4 g of lubricant; the transparent agent is acrylic resin, the surfactant is fatty alcohol polyoxyethylene ether, and the water-resistant agent is urea-formaldehyde resin , the lubricant is calcium stearate; the solid content of the impregnating liquid is 10%.

[0045] making process:

[0046] The base paper was soaked in the soaking solution for 10 s and the soaking amount was 20%, and then it was taken out, and then the soaked paper was closely attached between two film materials, the film...
