Problems solved by technology

Under normal circumstances, when using ordinary wear-resistant paper with wear-resistant agent to press the floor, a template must be replaced after 4000 pressures before it can continue to be used, otherwise the gloss of the floor surface will be significantly reduced, seriously affecting the quality of the floor. The brightness and clarity of the laminated wood flooring, the produced laminated wood flooring cannot meet the requirements of customers
The second is that the wear-resistant agent is coated on the base paper during th

Abstract

The invention belongs to the technical field of paper making, and particularly relates to high-permeability paper and a preparation method thereof. The high-permeability paper is prepared from the following raw materials in percentage by weight: 90 to 97 percent of wood pulp and 3 to 10 percent of auxiliary agents, wherein the wood pulp is metered by the dry weight. The high-permeability paper has the characteristics of high permeability, high ventilation performance, high uniformity, high gumming quantity and high softness; through lower steam customer gumming, wear-resistant materials are sprayed and coated onto the paper surface; after the high-temperature pressing and pasting, the high-permeability paper can be made into a reinforced wood floorboard; high glossiness and stable wear-resistant turn number are realized; the definition reaches the effect incomparable by the ordinary wear-resistant paper; the market prospects are very wide; the preparation method is scientific, reasonable and simple; the implementation is easy.

Description

Technical field [0001] The invention belongs to the technical field of papermaking, and specifically relates to a high permeability paper and a preparation method thereof. Background technique [0002] At present, there are three production processes for surface wear-resistant paper. The first is to add wear-resistant materials to the pulp during the production of base paper. In the produced wear-resistant paper, the wear-resistant materials are not covered in the fiber, and most of them are Outside the fiber, during the hot pressing process of the wooden floor, the wear-resistant material is in close contact with the template, which causes a large degree of wear to the template. Under normal circumstances, when using ordinary wear-resistant paper with wear-resistant agent to press the floor, a template must be replaced after 4000 presses to continue to use it, otherwise the gloss of the floor surface will be significantly reduced, which will seriously affect The brightness and ...
