Embodiment 1

[0023] Configure water-based moisture retention paint:

[0024] (1) Preparation of partially hydrolyzed ethylene-vinyl acetate copolymer: Vinyl acetate and ethylene monomers are used as basic raw materials, among which 70g of vinyl acetate and 30g of ethylene are copolymerized by emulsion polymerization to obtain ethylene-vinyl acetate copolymers 100g of the emulsion, and then partially hydrolyzed under the action of 15% NaOH to obtain 100g of partially hydrolyzed ethylene-vinyl acetate copolymer with a degree of hydrolysis of 35%;

[0025] (2) Mix 20g of waterborne acrylic copolymer with a weight ratio of methyl methacrylate-ethyl acrylate-butyl acrylate copolymer: polyacrylic acid=1:1, 20g polyvinyl acetate and 50g water to obtain Mixed emulsion

[0026] (3) Stir the partially hydrolyzed ethylene-vinyl acetate copolymer and add the mixed emulsion. After stirring evenly, add 4g of Foamex902 antifoaming agent and 2.5g of O2C preservative and continue to stir for 25min to obtain a wa...

Abstract

The invention discloses a production process and a production system of a high-barrier cigarette-use moisture-retaining paper. The process comprises the following steps: passing the base paper through a first coating device, coating a layer of insulation layer on one side of the base paper, and then passing the base paper through the first coating device. The first oven drying continues to pass through the second coating device, and a layer of moisture-retaining layer is coated on the top of the insulating layer, and after drying in the second oven, the third coating device is used to coat the insulating layer and the moisture-retaining layer The other side is coated with a printed graphic layer, dried in a third oven, and rolled up to obtain a moisturizing paper. Its production system includes a paper unwinding device, a first coating device, a first oven, a second coating device, a second oven, a third coating device, a third oven and a winding device. The invention is safe, environment-friendly, low in cost, simple and convenient in process flow, capable of continuous production, ensures that the whole process can be completed in one start-up, saves manpower and resources, and the prepared moisture-retaining paper for high-barrier cigarettes has uniform coating and excellent moisture-retaining performance.

Description

Technical field [0001] The invention relates to the field of coated paper, in particular to a production process and a production system of a high-barrier cigarette moisturizing paper. Background technique [0002] Coated paper is a packaging paper that is coated with one or more layers of paint on the base paper to have good optical, printing, barrier and other properties. With the advancement of science and technology and the improvement of people's living standards, people have higher and higher requirements for coated paper. Especially in the food and cigarette industries, single-layer coated paper has been difficult to meet the requirements of high barrier properties. As a result, companies in the industry focused their attention on the development of multilayer coated paper. [0003] Usually, the basic process of paper coating at one time is: unwinding-coating-drying-winding. For the multi-layer coating of coated paper, the traditional process involves one coating, and the...
