In view of the characteristics of biomass-based wood adhesives in their production, storage and application, wood adhesive preservatives must meet the following basic requirements: 1 efficient broad spectrum. Anti-mildew, anti-corrosion effect is obvious, and the amount added is small. Long-lasting effect, wide range of use; 2 good compatibility. After the addition, it does not react with other components of the adhesive residue, and does not affect the storage, travel and performance of the adhesive; 3 stability is strong. Non-volatile, non-sublimation, heat-resistant, light-resistant, chemical-resistant, does not change itself; 4 environmental protection. Non-toxic, odorless, does not harm health, does not pollute the environment; 5 cheap and easy to use, easy to use.
Commonly used wood adhesive fungicides and preservatives can be divided into 9 categories: 1 organic acids and their salts, such as benzoic acid, sodium benzoate, propionic acid, calcium propionate, sorbic acid, sodium diacetate, etc.; 7 isothiazole Linoleones, such as BIT, Carson CG, Huake-981; 3 benzoxazolines, such as EF-O2, preservative O; 4 phenols, such as sodium pentachlorophenol; 5 nano fungicides, such as nano-TiO And Ag; 6 nitrites, such as sodium nitrite; 7 organic enoic acids, such as dodecyl succinic acid; 8 organic amines. Such as dicyclohexylamine, triethanolamine; 9 benzotriazole, methylbenzotriazole, methylbenzotriazole 5O% sodium salt.
