Abstract

The invention discloses a composite base paper and a preparation method thereof. The composite base paper is prepared from the following raw materials in parts by weight: 100-110 parts of softwood pulp, 780-815 parts of hardwood pulp, 350-360 parts of kaolin, 210-220 parts of ferrite yellow, 35-40 parts of iron oxide red, 40-90 parts of magnesium soap powder, 15-30 parts of ultra-fine silica aerogel, 15-30 parts of boron nitride micropowder, 8-19 parts of sea-foam stone powder, 12-18 parts of Chinese chestnut shell micropowder, 14-21 parts of watercraft acrylic resin, 20-35 parts of potato starch, 3-11 parts of polypropylene fiber, 5-8 parts of propylgallate, 6-18 parts of nanoscale BaTiO3 powder, and 8-12 parts of urea formaldehyde resin. The composite base paper can be guaranteed not to be changed in color, deformed and cracked after being used for a long time, and has no influence on other performances of decorative paper, thus being good in usage effect.

Description

Technical field [0001] The invention relates to a base paper, in particular to a composite base paper and a preparation method thereof. Background technique [0002] Decorative base paper is a kind of industrial special paper processed by special technology with high-quality wood pulp and titanium dioxide as main raw materials. After printing and melamine resin dipping, it is mainly used for fiberboard, particleboard and other artificial boards. , Surface layer paper and bottom layer paper. When the decorative base paper is used as a protective layer paper, it will be exposed. It may not only be exposed to sunlight, but also corroded by water vapor or carved by hard objects. Therefore, the decorative base paper will have some quality problems after long-term use: for example: Discoloration, deformation, and cracking. Once the decorative base paper has a problem, it is impossible to repair it. Due to the composite process of the decorative base paper and the board, when the deco...
