Problems solved by technology

[0003] Most of the existing aluminum foil papers use adhesives to bond the aluminum foil layer and the substrate layer, and some of them are coated with aluminum after sizing the surface of the substrate layer. No matter what kind of process, the substrate layer is required. A large amount of industrial waste liquid is produced, which not only pollutes the environment but also consumes huge costs in the later stage of waste liquid treatment, and the used waste paper is directly disposed of to waste resources and pollute the environment
[0004] The existing aluminum foil paper is also compounded on the surface of the aluminum foil layer by mixing the pulp and the adhesive, but the direct mixing of the pulp and the adhesive will not only affect the adhesive performance of the adhesive, but also the uneven mixing will easily lead to the preparation The paper layer breaks away from the aluminum foil layer during use

Abstract

The invention discloses an environment-friendly and energy-saving waterproof aluminum foil paper and a preparation process thereof. The aluminum foil paper includes an aluminum foil layer and a composite paper layer. The composite paper layer is uniformly coated with a layer of gelled pulp on one side of the aluminum foil layer by a coating roller. Then spray a layer of paraffin wax on the surface of the gelled pulp layer. The aluminum foil paper of the present invention is prepared into gelatinized pulp by pulverizing discarded paper and then carrying out gelation reaction, and then directly coating the gelatinized pulp on the surface of the aluminum foil layer and then spraying a layer of paraffin to form waterproof aluminum foil paper. Using a clean matrix layer not only saves the cost of producing the matrix layer, but also realizes the recycling of waste paper, and at the same time effectively prevents the production of a large amount of industrial waste liquid in the process of producing the layer, causing environmental pollution and the cost of wastewater treatment.

Description

technical field [0001] The invention belongs to the field of cigarette materials, and relates to an environment-friendly and energy-saving waterproof aluminum foil paper and a preparation process thereof. 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. Aluminum foil paper is widely used, such as: aviation food packaging, ordinary meat packaging, cigarette packaging, etc. [0003] Most of the existing aluminum foil papers use adhesives to bond the aluminum foil layer and the substrate layer, and some of them are coated with aluminum after sizing the surface of the substrate layer. No matter what kind of process, the substrate layer is required. A large amount of industrial waste liquid is produced in the process, which not only pollutes the environment but also consumes huge costs in the later treatment of the waste liquid, and the used...
