Abstract

The invention discloses a composite modified environment-friendly metal corrugated pipe adhesive and a preparation method of the composite modified environment-friendly metal corrugated pipe adhesive. The composite modified environment-friendly metal corrugated pipe adhesive is prepared from, by weight, 16-35 parts of polyvinyl alcohol, 13-28 parts of corn starch, 13-26 parts of konjaku flour, 12-27 parts of chitosan, 11-19 parts of konjac gulcomannan, 11-22 parts of sodium borate, 3-11 parts of aluminum oxide, 8-19 parts of sodium hydroxide, 6-17 parts of magnesium sulfate and 6-18 parts of ferric sulfate. The composite modified environment-friendly metal corrugated pipe adhesive is long in adhesion time and high in adhesion strength, and has good waterproof performance and good corrosion resistance.

Description

technical field [0001] The invention belongs to the field of material chemistry and relates to an adhesive, in particular to a composite modified environment-friendly metal bellows adhesive and a preparation method thereof. Background technique [0002] Polyvinyl alcohol is a water-soluble polymer with a wide range of uses and unique properties. It is widely used in the production of coatings, adhesives, emulsifiers, paper processing agents, textiles, and plastic films. As a rapidly developing hot-melt adhesive, polyvinyl alcohol has good strong adhesion, high film strength, toughness and transparency, oil resistance, solvent resistance, corrosion resistance, wear resistance, and good gas barrier properties. Thermal stability, suitable for bonding wood-based panels, blockboards, plywood, particleboard, high-density fiberboard, etc., with the characteristics of simple manufacturing process and fast curing speed. However, the characteristics of polyhydric water-soluble polyme...
