Abstract

The invention discloses waterproof abrasive paper raw paper, and relates to the technical field of abrasive paper. The waterproof abrasive paper raw paper is prepared from the following raw materials in parts by weight: 15 to 20 parts of needle leaf wood pulp fiber, 15 to 20 parts of broadleaf wood pulp fiber, 10 to 15 parts of corn fiber, 10 to 15 parts of polyester fiber, 5 to 10 parts of ramie fiber, 25 to 35 parts of epoxy modified alkyd resin, 6 to 8 parts of water-proofing agents and 6 to 8 parts of oil-proof agents; the epoxy modified alkyd resin is prepared from the following raw materials in parts by weight: 75 to 85 parts of epoxy resin, 3 to 5 parts of linseed oil, 10 to 15 parts of driers, 30 to 35 parts of pentaerythritol, 8 to 10 parts of phthalic anhydride, 3 to 5 parts of organic tin catalysts and 3 to 5 parts of rosin. The waterproof abrasive paper raw paper has the advantages that the toughness can be maintained; good bonding performance can also be realized.

Description

technical field [0001] The invention relates to the technical field of sandpaper, in particular to a water-resistant sandpaper base paper. Background technique [0002] Sandpaper is an abrasive tool made by adhering abrasive materials on a soft substrate with adhesives. The main raw materials of sandpaper are base paper, abrasive materials, and adhesives. In order to improve the grinding strength of the sandpaper, the base paper is not only required to be tough, but also wear-resistant and fold-resistant, and has good water resistance. [0003] Water-resistant sandpaper is mainly used as water-resistant sandpaper base paper after water-resistant impregnation treatment of kraft paper in my country. At present, the production of water-resistant sandpaper in China has been using the traditional alkyd varnish, alkyd enamel, amino resin paint and alkyd thinner as binders, and is manufactured by a suspended continuous production line. [0004] Alkyd resin has excellent comprehen...
