Problems solved by technology

However, most of the existing kraft linerboards on the market cannot meet this requirement.
[0003] The traditional kraft liner paper is formed by using multi-layer nets separately, and then the multi-layers are combined together to produce it. Therefore, the bonding force between the layers of the kraft liner paper is often not as strong as that between the fiber layers. , resulting in poor bonding strength between layers, and the finished paper is easy to delaminate during use, which affects the use effect

Abstract

The invention belongs to the technical field of special paper preparation and particularly relates to high-strength flame-retarding kraft board paper, a preparation method and an application thereof. The preparation method includes the steps of: filling a surface layer, a core layer and a bottom layer of the kraft board paper with aluminum hydroxide; spraying the surface layer, the core layer and the bottom layer of the kraft board paper with starch and ammonium polyphosphate; after the surface layer, the core layer and the bottom layer are laminated, spraying the surface of the kraft board paper with the ammonium polyphosphate. In the high-strength kraft board paper, each layer is not only sprayed with the starch but also sprayed with the ammonium polyphosphate and filled with the aluminum hydroxide, so that the kraft board paper has excellent reinforcing and flame-retarding effects, has excellent physical and fire-proof performance and can be used in the various fields such as packaging and the like well.

Description

technical field [0001] The invention belongs to the technical field of special paper preparation, and in particular relates to a high-strength flame-retardant kraft liner board and its preparation method and application. Background technique [0002] Kraft linerboard is one of the main packaging papers, mainly used for packaging household appliances, daily necessities, knitted cotton fabrics, stationery, Chinese and Western patent medicines, etc. For the fire safety of the products, these packaged products require high flame retardancy of kraft liner paper. However, most of the existing kraft linerboards on the market cannot meet this requirement. [0003] The traditional kraft liner paper is formed by using multi-layer nets separately, and then the multi-layers are combined together to produce it. Therefore, the bonding force between the layers of the kraft liner paper is often not as strong as that between the fiber layers. , resulting in poor bonding strength between la...
