Abstract

The invention discloses a low-temperature boron-free starch adhesive for paper products and a preparation method thereof. The components and parts by weight of the adhesive are: 100 parts of corn starch, 320-400 parts of water, and 2.3-400 parts of potassium permanganate. 2.6 parts, 0.5-0.8 parts of sodium fatty acid, 2-2.4 parts of oxalic acid, 0.3-0.5 parts of tributyl phosphate, 8-12 parts of sodium hydroxide, 1.2-1.8 parts of sodium trimetaphosphate, 3-5 parts of drier, The adhesive with this formula has a simple production process and does not require heating. It only takes 40-50 minutes from feeding to the finished product. The adhesive cartons dry quickly, have high strength, do not run rough, do not absorb moisture, do not flood, and do not pan-alkali , long storage period, the viscosity remains unchanged after storage for 3 months, no mildew and precipitation, initial adhesion is 1-1.5min, full adhesion is 5-10min, fiber damage is 30-50s, the relevant physical and chemical indicators are better than the national standard requirements, and can be widely used Corrugated boxes for general commodity packaging and corrugated boxes for food packaging.

Description

technical field [0001] The invention relates to an adhesive, in particular to a starch adhesive for corrugated cardboard production line, laminating paper, carton or cardboard and other adhesive paper products. Background technique [0002] my country's corrugated packaging industry is an industry with large scale, high energy consumption and large pollution sources. Traditional corrugated cardboard production needs to use high temperature to gelatinize starch raw glue for cardboard bonding. Usually, 8-12 kg of steam pressure is required. Most of the steam is supplied by coal-fired boilers, which not only consumes a lot of energy, but also pollutes the combustion emissions. environment. [0003] In addition, there are problems in the industry such as poor adhesion of high-strength sized corrugated paper, complex glue-making process, poor glue stability, slow drying speed, and poor moisture resistance of the glued film, which have become technical problems that the industry ...
