Abstract

The invention relates to a quick-drying cold-forming starch toughening glue and a preparation method thereof. The quick-drying cold-forming starch toughening glue comprises the following materials with the following weight portions: 320 portions to 670 portions of starch, 1 portion to 5 portions of postassium pyroantimonate, 6 portions to 20 portions of exsiccated alum, 7 portions to 15 portions of light magnesium oxide, 5 portions to 20 portions of borax, 4 portions to 19 portions of solid natrium hyelroxide, 0.5 portion to 2 portions of aluminum sulfate, 3 portions to 12 portions of polyvinyl alcohol, 1 portion to 10 portions of expansion agent and 1030 portions to 1510 portions of water. The invention also includes the preparation method of the quick-drying cold-forming starch toughening glue. The quick-drying cold-forming starch toughening glue has low manufacturing cost, good storage performance, high bounding strength, high bounding speed and good water proof performance, and can be formed in cold conditions and be used as the adhesive for paper plates, paper boxes and the like and also as the toughening agent in paper manufacturing process.

Description

technical field [0001] The invention relates to a starch glue and a preparation method thereof, in particular to a quick-drying cold-setting starch glue and a preparation method thereof. Background technique [0002] For a long time, corrugated cardboard factories and color printing factories have mostly used starch glue in the process of bonding cardboard, cartons, and cartons. [0003] At the same time, it is an important direction for future development to directly beat waste paper into corrugated cardboard. In order to improve the strength of waste paper after molding, it is also necessary to add starch glue to pulp to improve the bonding strength between pulp fibers. [0004] At present, the starch glue sold in the market has the disadvantages of slow bonding speed, low bonding strength, poor water resistance, and heating is required during the bonding process. Contents of the invention [0005] The purpose of the present invention is to overcome the defects existing...
