Problems solved by technology

[0003] At present, the adhesives for corrugated cardboard mainly used in my country usually use starch as raw material. Although starch adhesives are widely sourced, rich in content, non-toxic, non-polluting, and low in cost, they are greatly affected by temperature and composition, and their performance is not good. Stable, and the drying temperature is too high during use, which cannot meet the needs of high-speed production, prone to precipitation, poor permeability, sometimes false sticking, foaming, and degumming, resulting in low productivity, high production costs, and unstable product quality And other issues

Abstract

The invention provides a low-temperature corrugated paper glue, comprising the following raw materials in parts by weight, cassava flour 100-600, caustic soda 5-20, salt 1-15, borax 1-6, red powder 0.1-5, bridging agent 1-20, stable Agent 1‑8, water 500‑2000. The corrugated paper glue of the present invention can reduce the amount of heating steam during use. When a batch of corrugated paper is bonded, it is reduced from the previous 8-9 kg of steam to less than 5 kg of steam, and the heating process is reduced, and the cost is reduced. .

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a glue for low-temperature corrugated paper. Background technique [0002] Corrugated cardboard, also known as corrugated cardboard, is made of at least one layer of corrugated paper and one layer of cardboard paper, which has good elasticity and extensibility. It is mainly used in the manufacture of cartons, the sandwich of cartons and other packaging materials for fragile goods. [0003] At present, the adhesives for corrugated cardboard mainly used in my country usually use starch as raw material. Although starch adhesives are widely sourced, rich in content, non-toxic, non-polluting, and low in cost, they are greatly affected by temperature and composition, and their performance is not good. Stable, and the drying temperature is too high during use, which cannot meet the needs of high-speed production, prone to precipitation, poor permeability, sometimes false sti...
