Abstract

The invention relates to the field of glue, in particular to a paper adhesive. The paper adhesive comprises the following components in parts by mass: 150-180 parts of vinyl acetate, 100 parts of polyvinyl alcohol, 10 parts of starch, 2 parts of ammonium persulfate, 2 parts of an OP10 emulsifier, 20 parts of glyoxal, 1 part of baking soda, 3-5 parts of oxalic acid and the balance of water. The paper adhesive has the advantages that the raw materials are harmless, the compounding is reasonable, the process is perfect, the efficiency is high, no harm is caused, and the product quality is qualified.

Description

technical field [0001] The invention relates to the field of glue, in particular to a face paper glue. Background technique [0002] Adhesive for paper tubes, commonly known as face paper glue, is a special adhesive for making various paper tubes, paper barrels, paper cans and related paper products. All kinds of products have special requirements for paper glue depending on their usage. When making high-speed spinning POY and low-speed stretched DTY paper tubes for polyester plants, the paper tubes are required to have a good combination of high enough compressive strength, hardness, toughness, water resistance, heat resistance and creep resistance. performance. In fact, the above properties depend to a considerable extent on the performance of the face paper glue used, that is, the face paper glue needs to have the following properties: [0003] 1) Good physical properties, milk jelly, non-toxic, tasteless, long storage period. [0004] 2) Good machine performance, les...
