Hot melt adhesive capable of improving waste discharge effect and preparation method thereof

The invention discloses a hot melt adhesive capable of improving a waste discharge effect and a preparation method thereof. The hot melt adhesive comprises the following raw materials in parts by mass: 30-45 parts of styrene thermoplastic elastomer, 40-55 parts of tackifying resin, 1-4 parts of modified polyethylene wax and 11-21 parts of a mixed additive. The hot melt adhesive is not prone to causing backflow adhesion, the die cutting waste discharge effect can be improved, and the rejection rate of label production using the hot melt adhesive is reduced. The invention further discloses a preparation method of the hot melt adhesive. The die cutting waste discharge effect is improved, the technology is simple, and the operability is strong. 本发明公开了一种可提升排废效果的热熔胶及其制备方法，按照质量份数，一种可提升排废效果的热熔胶包括以下原料组分：苯乙烯热塑性弹性体30～45份、增粘树脂40～55份、改性聚乙烯蜡1～4份和混合助剂11～21份。本技术方案提出的一种可提升排废效果的热熔胶，其不易引起回流粘连，有利于提升模切排废效果，降低使用其的标签生产废品率。进而提出一种上述可提升排废效果的热熔胶的制备方法，能有效确保热熔胶达到提升模切排废效果，具有工艺简单、操作性强的特点。
