High-strength quick-drying energy-saving environment-protective cardboard box glue

Abstract

The invention pertains to the field of new materials, particularly relates to a high-strength, drip-dry, energy-saving and environmentally-friendly paper carton adhesive. Water is filled in a high-speed stirred vessel, stirred, added with a catalyst and after a few minutes, added with flour, stirred and then added with an oxidant and a gelatinization agent, kept being stirred at a constant speed, added with a filler and finally added with a crosslinking agent, stirred for 10 min to 30 min so as to form the adhesive which is characterized in that: the components thereof calculated by weight percentage are 40 percent to 80 percent of the water, 0.01 percent to 0.5 percent of the catalyst, 10 percent to 30 percent of the flour, 1 percent to 8 percent of the oxidant, 2 percent to 8 percent of the gelatinization agent, 0 percent to 30 percent of the filler and 0.01 percent to 6 percent of the crosslinking agent. The adhesive of the invention has the functions of high strength, getting dry quickly and water resistance, and is technologically characterized in that: the speed, from oxidation to gelatinization to gelatinization, is quick; during the oxidation, an organic catalyst is combined with an inorganic metal salt and oxidation is combined with assisted oxidation, therefore, the substances such as starch, etc. can be oxidized into adhesive water with high viscosity and without wiredrawing at a high speed in a short time, and the problem of over-oxidation cannot occur.

Description

technical field [0001] The invention belongs to the field of new materials, in particular to a high-strength, quick-drying, energy-saving and environment-friendly carton glue in the production process of cartons and cardboards. Background technique [0002] As we all know: the carton industry is developing rapidly and the demand is large. In the production process of cartons, starch glue, sodium hydroxide and other latex and other synthetic glues are mainly used. my country is a large agricultural country with a wide range of sources of starch and low prices. The development of a high-strength, quick-drying, energy-saving and environmentally friendly carton glue used in the production of cartons and cardboards has broad prospects. [0003] Starch is a polyhydroxy compound with many anhydroglucose units connected by sugar bonds. There is an alcoholic hydroxyl group at the 2, 3, and 6 positions of each anhydroglucose unit, so there are a large number of reactive groups in the...

AI Technical Summary

Problems solved by technology

If the starch content is too large, the glue will lose fluidity and bond strength will decrease after standing for several days

[0005] At present, the main disadvantages of the glue used in the domestic carton industry are poor moisture resistance and low strength.
