Problems solved by technology

[0014] In order to solve the problems of poor thermal stability, low rigidity and high production cost of the paper surface film caused by simply using resin as the coating material, the present invention provides a modified coating paper and its manufacturing method, which adopts low-density polyethylene with low linearity. The PE material is composed of density polyethylene to ensure that the PE material has the characteristics of softness, corrosion resistance, heat resistance, and impact resistance. Dimensional stability, while achieving the purpose of reducing production costs

Embodiment Construction

[0028] 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.

[0029] Such as Figure 1-2 As shown, the modified coated paper is a double-layer layered structure composed of a modified PE film 2 and a base paper 1, and the modified PE film 2 is attached to the surface of the base paper 1.

[0030] The PE material is composed of low-density polyethylene and low-density linear polyethylene in a ratio of 1:1. The modified PE film 2 is formed by mixing and extruding a nano-calcium carbonate modified powder and PE particles. The ratio of the nano-calcium carbonate modified powder and PE particles is 12:88, and the modified PE coating amount is 12-25g / m 2 .

[0031] A modified coated paper and a manufacturing method thereof, comprising the following steps: raw material mixing and melting—base paper unwinding—corona—high tempera...

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

[0001] Divisional application: [0002] Original filing date: November 30, 2011 [0003] Original application number: 201110389736.9 [0004] Original title of the invention: Modified coated paper and its manufacturing method technical field [0005] The invention relates to paper coating production technology, in particular to a modified coating paper and a manufacturing method thereof. Background technique [0006] 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. [0007] The adhesive film material on the coated paper generally uses PE resin, and its production method is as follows. [0008] Paper selection: base paper with appropriate thickness, specification and material is selected as the base material according to the preparation of the final product. [0009] Corona: shock the base paper surface to increa...
