Description

1. Technical field

[0001] The invention relates to an adhesive, especially a cationic pullulan wood adhesive; the invention also relates to a preparation method of the adhesive. 2. Background technology

[0002] With the scarcity and shortage of wood resources, the application of wood adhesives is becoming more and more extensive. At present, among wood adhesives, formaldehyde series adhesives are most widely used. Formaldehyde series adhesives will release harmful gases such as free formaldehyde during use, seriously polluting the environment, and causing people to worry about environmental protection. There are two types of adhesives: synthetic polymer adhesives and natural polymer adhesives. Formaldehyde series adhesives belong to the category of synthetic polymer adhesives. Synthetic polymer adhesives generally have the advantages of small molecular weight, good wettability, and high bonding strength, and become the mainstream of wood adhesives. . Natural adhesives are...
