Problems solved by technology

The Chinese patent authorization announcement number is CN105220570B, which is a patent document called a production method of scientific and technological ecological impregnated paper. Adhesive paper with high grinding performance, but the amount of formaldehyde used in the preparation of urea-formaldehyde glue is too high, while the amount of urea is relatively low, urea cannot fully combine formaldehyde, and the release of free formaldehyde will exceed the standard during long-term storage
The Chinese patent publication number is CN201611231078, which is called the patent document of the production process of wear-resistant decorative paper. It also discloses a method for preparing film paper by impregnating urea-formaldehyde glue and spraying base paper with melamine glue. However, due to the large amount of content in urea-formaldehyde glue The active group makes the cross-linking degree of the glue too high, resulting in high brittleness of the glue and reducing the wear resistance
[0004] It can be seen that the current wear-resistant impregnated film paper has the problems of high formaldehyde emission and low wear resistance. Therefore, it is necessary to develop a durable and environmentally friendly wear-resistant impregnated film paper

Wherein, the preparation raw material of wear-resistant melamine glue is formaldehyde, melamine, water, 301 auxiliary agent and sodium hydroxide aqueous solution; The preparation raw material of wear-resistant auxiliary agent is chitin, hexadecyltrimethoxysilane, water, hydrochloric acid, Aqueous sodium hydroxide solution and trehalose‑6,6′‑dimycolate. The adhesive film paper prepared by the invention has high wear resistance, flexibility and environmental protection, and can realize low formaldehyde emission and long-term durability. The preparation method of the invention has simple steps, controllable process and is suitable for large-scale production.

Description

【Technical field】 [0001] The invention relates to the technical field of decorative paper, in particular to a wear-resistant impregnated film paper and a preparation method thereof. 【Background technique】 [0002] Impregnated film paper is a kind of impregnated paper (referred to as film paper) that is made of base paper impregnated with amino resin or phenolic resin, dried to a certain degree of curing, and can be bonded to each other or coated on the surface of wood-based panels by hot pressing. [0003] Various patterns can be printed on the surface of the base paper, and the film paper can be obtained by impregnation. The wood-based panel finished with the film paper has the characteristics of various designs and colors, elegant appearance, relatively low price, and easy cleaning. The wood-based panels impregnated with film paper do not need secondary coating, and can be directly used for surface decoration, interior decoration and floor covering of furniture, buildings ...
