Abstract

The invention discloses an anti-corrosion and anti-ageing adhesive for a paperboard. The anti-corrosion and anti-ageing adhesive for the paperboard comprises the following raw materials in parts by weight: 25-35 parts of aromatic isocyanato, 5-15 parts of polypropylene glycol, 15-20 parts of polyester diol, 40-60 parts of gelatinized starch, 5-15 parts of oxhide gelatin, 1-6 parts of bone glue, 5-15 parts of modified whey protein composite microparticles, 5-15 parts of soy protein, 1-2 parts of bis (dioctylpyrophosphate) ethylene titanate, 1-2 parts of sodium dodecyl sulfate, 0.5-1.2 parts of tebuconazole, 1-2 parts of tea polyphenol, 0.2-1 part of chitosan, 1-5 parts of ricinoleic acid, and 20-40 parts of water. The anti-corrosion and anti-ageing adhesive for the paperboard is good in anti-corrosion property and anti-ageing property and excellent in toughness and heat stability.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an anti-corrosion and aging-resistant adhesive for cardboard. Background technique [0002] Water-based adhesives use water as the dispersion medium, are odorless, non-polluting, and are environmentally friendly adhesives. However, with the depletion of non-renewable resources such as petroleum, the price of crude oil continues to rise, and the production cost of synthetic polyurethane is increasing day by day. At the same time, water-based polyurethane also has problems such as lower cohesive energy than polar substrates and weak adhesion. Starch is rich in polar groups, and its molecular structure is very similar to the cellulose structure in bamboo and wood, so it has strong adhesion to wood, paper, etc., and starch is a green renewable resource with low price. However, the anti-corrosion and aging resistance are poor, the toughness is poor, and the thermal stability is no...
