[0003] The purpose of the present invention is to provide a preparation process of recyclable aluminum foil paper, by compounding a layer of mesh cloth between the aluminum foil layer and the paper base layer, since the adhesive is bonded to the mesh cloth, the adhesive is in the form of a mesh Distribution, after compounding with the aluminum foil layer and the paper base layer, the adhesive is distributed in a net shape between the paper base layer and the grid cloth and between the grid cloth and the aluminum foil layer, not only to achieve uniform distribution of the adhesive, but also to make the aluminum foil The paper is evenly bonded, and the adhesive is not fully covered, and it is easy to peel off when recycling aluminum foil paper, which solves the problem of difficult peeling when aluminum foil paper is recycled in the prior art

Embodiment 1
[0026] The preparation process of the water-absorbing adhesive is as follows: add 1kg of oxidized starch to water to prepare a starch paste, stir and disperse evenly, then raise the temperature to 40°C, then add 0.12kg of 2,3-epoxypropyltrimethylammonium chloride to it, and react at constant temperature 5h, then filtered, washed and dried to obtain a water-absorbing adhesive.
Embodiment 2
[0028] A preparation process of recyclable aluminum foil paper, the specific preparation process is as follows:
[0029] The first step is to soak the mesh cloth in the water-absorbing adhesive, then take out the impregnated mesh cloth, and bond the bottom surface of the mesh cloth to the surface of the base paper through the water-absorbing adhesive, and at the same time, glue the bottom surface of the aluminum foil layer Composite on the surface of the mesh cloth; the thickness of the mesh cloth is 0.08-0.1mm, and the mesh cloth is made of glass fiber;
[0030] In the second step, the aluminum foil paper bonded in the first step is pressed by a pressure-adjusting compound machine to obtain recyclable aluminum foil paper.
Embodiment 3
[0032] Such as figure 1 , figure 2 with image 3 As shown, the adjustable composite machine includes two oppositely arranged and vertically distributed support plates 1, and the top joint plate 2, the sliding bearing seat 3 and the bottom support shaft are installed and fixed sequentially from top to bottom between the two support plates 1 4;
[0033] The bottom of the side wall of the support plate 1 is provided with a first rotation hole 11, and the two ends of the bottom support shaft 4 are installed in the bearings in the first rotation hole 11, and one end of the bottom support shaft 4 is connected with the power of the first reduction motor. The output is connected;
[0034] Such as image 3 , 4As shown, the middle part of the side wall of the support plate 1 is provided with a strip-shaped clamping hole 12, and the sliding bearing seat 3 includes a bearing plate 31 at the same time. Shaped block 311, the sliding bearing seat 3 is clamped in the bar-shaped clampin...

Abstract
The invention relates to a preparation process of recoverable aluminum-foil paper, which comprises the following steps of: impregnating gridding cloth in a water absorption adhesive, taking out the impregnated gridding cloth, bonding the bottom surface of the gridding cloth on the surface of base paper through the water absorption adhesive, and compounding the bottom surface of an aluminum foil layer on the surface of the gridding cloth; and pressing the aluminum-foil paper bonded in the first step through a pressure regulating type compound machine to obtain the recoverable aluminum-foil paper. According to the invention, a layer of gridding cloth is compounded between the aluminum foil layer and a paper base layer; the adhesive is bonded on the gridding cloth, the adhesive is distributedin a net shape, after the adhesive is compounded with the aluminum foil layer and the paper base layer, the adhesive is distributed between the paper base layer and the gridding cloth and between thegridding cloth and the aluminum foil layer in a net shape; the adhesive is uniformly distributed, so that the aluminum-foil paper is uniformly bonded, the adhesive is not completely covered, the aluminum-foil paper is easy to strip when being recycled, and the problem that the aluminum-foil paper is difficult to strip when being recycled in the prior art is solved.
Description
technical field [0001] The invention belongs to the technical field and relates to a preparation process of recyclable aluminum foil paper. Background technique [0002] As a raw and auxiliary material for industrial manufacturing, aluminum foil paper is mainly used in packaging protection, daily necessities, construction, etc. The existing aluminum foil paper is directly laminated on the surface of the aluminum foil layer during the preparation process, and the two layers are bonded After bonding, it is calendered by a calender. The strength of the prepared aluminum foil paper is low, and it is difficult to peel off after the recycling process. The invention patent with application number 92111296.3 discloses a method for recycling aluminum from waste aluminum foil paper And the device, the invention directly crushes the aluminum foil paper, so that the separation of the base paper and the aluminum foil is not complete, and the aluminum foil layer is damaged, so it is diffi...
