High-definition high-bulk wear-resistant paper and preparation method thereof

Abstract

The invention belongs to the technical field of surface wear-resistant paper, and particularly relates to high-definition high-bulk wear-resistant paper and a preparation method thereof. The raw materials comprise, by mass, the following components: 40-85% by dry component of wood pulp, 10-50% of a filler and 5-10% of an auxiliary agent; wherein the filler is aluminum oxide, and the aluminum oxideis a mixture of aluminum oxide with the particle diameters of 90-130um and the particle diameters of 60-90um. The high-definition high-bulk wear-resistant paper has the advantages of good permeability, high air permeability, high uniformity, high sizing amount and high bulk, and is prepared into a reinforced wood floor after being impregnated with glue and pressed and pasted at high temperature,the wood floor has the advantages of high brightness, high definition and stable wear-resistant revolution, the definition reaches the effect that common wear-resistant paper cannot be simulated, andthe hot pressing frequency of the formwork is 5 times of that of common wear-resistant paper, the wear resistant paper is a resource-saving and environment-friendly product.

Description

technical field [0001] The invention belongs to the technical field of surface layer wear-resistant paper, and in particular relates to a high-definition, high-bulk wear-resistant 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. The wear-resistant paper produced by this process has no wear-resistant materials wrapped in the fibers. On the outside of the fiber, during the hot-pressing process of the wooden floor, the wear-resistant material and the formwork are pressed at high temperature, causing a great degree of wear to the formwork. Usually, when using ordinary wear-resistant paper with wear-resistant agents to press the floor, After 4000 pressings of a template, the template must be replaced before it can continue to be used, otherwise the surface gloss of the floor will be si...

Problems solved by technology

[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. The wear-resistant paper produced by this process has no wear-resistant materials wrapped in the fibers. On the outside of the fiber, during the hot-pressing process of the wooden floor, the wear-resistant material and the formwork are pressed at high temperature, causing a great degree of wear to the formwork. Usually, when using ordinary wear-resistant paper with wear-resistant agents to press the floor, A template must be replaced after 4000 presses to continue to use, otherwise the surface gloss of the floor will be significantly reduced, which will seriously affect the brightness and clarity of the laminate flooring

The laminate flooring produced by this process cannot meet the requirements of customers

[0003] The second is that the wear-resistant agent is coated on the base paper during the production process of the base paper. Due to the high speed of the paper machine, the dispersion of the wear-resistant material is uneven, resulting in unstable wear-resistant rotations of the wooden floor, which restricts people's normal use.

However, because the aluminum oxide used in the base paper is not completely covered in the middle of the base paper, the downstream customers will seriously affect the hot pressing times of the template when impregnating and laminating.
