Problems solved by technology

The whiteness of the paper is too high, and the reflection of light is strong. The book made of this kind of paper also stimulates the optic nerve, which leads to the loss of vision of teenagers and users.
In addition, due to the continuous cross-contact between the user groups during the use of the workbook, it is easy to be infected with bacteria and other microorganisms, so if the body's resistance is lowered, cross-infection may occur

Embodiment Construction

[0022] The present invention will be further described below in conjunction with embodiment.

[0023] A method for making a green protection workbook, the steps of the method are as follows:

[0024] a. Use PEFC / FSC and other certified paper with a yellow hue and no fluorescent substances as the inner core. The brightness and smoothness of the inner core meet the GB standard. The Lab values ​​of the inner core are: L∈92 ~98, a∈-0.2~-0.7, b∈4.55~7; choose kraft paper with yellow hue and no fluorescent substances as the cover, and the roughness of the cover is 2.5~3.0μm to achieve the purpose of changing the light reflection angle , used to reduce visual fatigue; the above-mentioned inner core and cover need to be dried and disinfected by drying cylinders and infrared equipment at a temperature not lower than 100°C during the production process; choose green hue ink and follow the 0.2-0.4g Add food-grade antibacterial ingredients to the ink to prepare printing ink at a ratio of / k...

Abstract

The invention discloses a manufacturing method for a green and protective exercise book. The manufacturing method comprises the following steps that a, paper in yellow is selected as an inner core, kraft paper in yellow is selected as a cover, green printing ink is selected, and a food grade antibacterial component is added into the printing ink according to the proportion of 0.2 g / kg -0.4g / kg sothat printing ink can be prepared; b, before printing and inking, the front faces and the rear faces of the inner core and the cover are coated with an antibacterial coating; c, the inner core and thecover in the step a are printed with the printing ink according to a setting; and d, the printed inner core and the cover are bound into the green and protective exercise book according to set specifications. According to the manufacturing method for the green and protective exercise book, by controlling the paper color, fluorescent materials and the printing oil and changing the optical performance of the paper, the effects of reducing visual fatigue, protecting the eyesight and preventing nearsightedness are achieved; and in the printing process, the food grade antibacterial component harmless to the human health is added, the green and protective effect is achieved, and the green and health product is provided for a market.

Description

technical field [0001] The invention relates to the technical field of stationery, in particular to a method for making a green protective workbook. Background technique [0002] At present, countries and regions such as Europe and South Korea stipulate that chlorine-containing bleaching agents and fluorescent whitening agents are not allowed to be used in office paper; One kilogram of fluorescent whitening agent, if the whiteness is below 87 degrees, the amount of whitening agent added will reach 7-8 times the original amount, and the bleaching agent and fluorescent whitening agent in the production process will be discharged into the water at night, causing serious pollution of water sources. Bleached paper contains adsorbable organic chloride (AOX) components, and adsorbable organic chloride (AOX) has teratogenic, carcinogenic, and disease-causing hazards. [0003] my country also has requirements and standards for the whiteness (brightness) and smoothness of paper. For ...
