Modified film-like aldehyde-free adhesive and use method thereof

The invention relates to a modified film-like aldehyde-free adhesive and a use method thereof. According to the present invention, high density polyethylene is used as a main body, a specially made material is added, and blow molding is performed to obtain the adhesion film, wherein the adhesion film has good tensile strength, good toughness, and good water resistance; when the modified film-like aldehyde-free adhesive and a wood veneer are combined, melting is performed at a high temperature and then cooling is performed under a high pressure, such that the molten polyethylene and the wood veneer can form the numerous solid adhesion nails, and the water resistance is strong; and the modified film-like aldehyde-free adhesive has characteristics of high plywood adhesion strength, no toxicity, no formaldehyde and low price, and can be popularized in large area. 本发明是种改性薄膜状无醛胶粘剂及其使用方法，以高密度聚乙烯为主体，加入特制配料，吹塑而成的胶膜，具有较好的抗张强度、韧性和防水性。当它与木材单板组合，在高温下熔化，而后又在高压下冷却时，熔融的聚乙烯能与木材单板形成无数的坚实胶钉，其防水能力很强。本发明特点：胶合板胶合强度高，无毒无甲醛，价格低，可以大面
