Embodiment Construction

[0025] In order to understand the technical features and practical effects of the present invention in more detail, the present invention will be further described below in conjunction with the accompanying drawings.

[0026] like figure 1 As shown, the modified coated paper has a double layered structure composed of modified PE or modified PP film 1 and base paper 2, and the modified PE or modified PP film 1 is attached to the surface of base paper 2.

[0027] The above-mentioned modified PE or modified PP film 1 is formed by mixing and extruding a nano-modified powder and PE or PP particles, and the ratio of the amount of the nano-modified powder to PE or PP particles is 12:88 , the coating amount of modified PE or PP is 18g / m 2 .

[0028] The manufacture method of modified coating paper, comprises the steps:

[0029] (1) The nano-modified powder is mechanically mixed with PE or PP at a mass ratio of 12:88;

[0030] (2) The temperature of the opening barrel is set to 185...

Abstract

The invention provides a modified polyethylene (PE) coated paper which is manufactured by the high pressure plying of modified PE or modified polypropylene (PP) films which are extruded under high temperature and double glue raw paper. The producing process of the modified PE coated paper comprises the following steps: raw materials mixing--raw paper decoiling--electric aureoling--high temperature coating membrane--hydraulic plying--cooling and forming--edge cutting--reeling up. The modified PE coated paper uses nano modifying powder to carry out modification on PE resin or PP resin, and the thermal stability and the rigidity of the PE coated paper are both improved. A modified PE coated film and the double glue raw paper, silicone oil and the modified coating membrane are all have strong adhesive force. Due to the fact that nano powder materials are mixed to modify the resin, compared with existing products, the modified polyethylene (PE) coated paper presents a unique matte finish effect, and a unique thick and solid feeling is obvious. Meanwhile, production cost is reduced.

Description

technical field [0001] The invention relates to paper coating production technology, in particular to a modified coating paper and a manufacturing method thereof. Background technique [0002] Coated paper is to corona-treat the base paper base material with a polymer film on one or both sides to make coated paper, which can improve the surface smoothness and waterproof performance of the base paper. [0003] The adhesive film material on the coated paper generally uses PE or PP resin, and its production method is as follows: [0004] Paper selection: base paper with appropriate thickness, specification and material is selected as the base material according to the preparation of the final product. [0005] Corona: shock the base paper surface to increase the roughness of the base paper surface to increase the adhesion between the polymer film and the base paper. [0006] High-temperature coating: PE or PP resin is used as the coating material to coat one side or both side...
