Abstract

The invention provides a production process of high-coverage synthetic paper and belongs to the field of production processes of paper products. The production process of the high-coverage synthetic paper specifically includes the steps of finishing raw materials, synthesizing a base film by using an acrylic adhesive layer, conducting aluminizing on the synthesized base film, conducting fitting onthe base film after aluminizing, conducting double-sided coating on the base film after fitting and conducting finishing and storage. Great printing performance is achieved during ink printing, and the production process has the advantage that the synthetic paper is resistant to bending and water; at the same time, an aluminizing layer fitting the interior of the synthetic paper improves the fitting strength, high coverage performance of a material is achieved with the lowest cost, and the optical density can reach 4.2 or above. The production process adopting a material aluminizing mode forimproving the coverage performance of the material is a simplest and most effective method for improving the coverage performance, the coverage performance of the material can be improved to the greatest extent by using an aluminizing material for opposite fitting, the aluminizing material fits the interior of the synthetic paper, the chromatic aberration of a surface material is not changed a lot, and therefore the normal appearance of the synthetic paper can be ensured.

Description

technical field [0001] The invention belongs to the technical field of paper product production technology, and in particular relates to a production technology of high covering synthetic paper. Background technique [0002] Synthetic paper is made by using chemical raw materials such as olefins and adding some additives. It has soft texture, strong tensile strength, high water resistance, light and heat resistance, and can resist corrosion of chemical substances without environmental pollution. , Good air permeability, widely used in the printing of high-end artworks, maps, picture albums, high-end books and periodicals, etc. [0003] Synthetic polymer materials (such as polyethylene, polypropylene, etc.) are made into semi-finished paper sheets by film drawing (film pressing or blown film), and then chemical or physical methods are used to make paper. For example, sanding can increase the Transparency, surface treatment with chemicals can achieve liquid repellency, etc. ...
