Abstract

The invention provides latex abrasive base paper, which is prepared from the following raw materials in parts by weight: 30-50 parts of cornstalk fiber, 100 parts of high-density cotton linter pulp, 5-12 parts of polypropylene fiber, 20-40 parts of alkali-free glass fiber chopped strands and 3-8 parts of a ceramic fiber; the base paper is prepared from the following raw materials in parts by weight: 0.1-4 parts of amphoteric polyacrylamide, 0.2-0.8 part of modified starch light calcium carbonate, 0-0.2 part of polyoxyethylene with the molecular weight of 2500000 to 3000000, 0-0.2 part of an antifoaming agent and 5-10 parts of latex. The latex abrasive base paper has the characteristics of being good in abrasive resistance, good in flexibility and high in tensile strength.

Description

technical field [0001] The invention relates to the technical field of paper, in particular to a latex sandpaper base paper and a preparation method and application thereof. Background technique [0002] Sandpaper is a kind of paper used for grinding, and latex sandpaper base paper is one of the raw materials used to make high-quality grinding sandpaper. It has the advantages of high grinding finish, low friction temperature, and high durability. It is mainly used for grinding cars. , Mold, etc. The latex sandpaper base paper currently on the market mainly has disadvantages such as poor wear resistance, poor flexibility, and low tensile strength, which seriously affect the quality and use effect of the finished paper. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a latex sandpaper base paper with good abrasion resistance, good flexibility and high tensile strength; the invention also provides a preparation method of...
