Abstract

The invention provides a hot melt adhesive formula and a manufacturing method of the hot melt adhesive formula. The hot melt adhesive formula comprises the following ingredients: 35-60 parts of EVA resin, 30-45 parts of a tackifier, 3-6 parts of ethylene-octene copolymers, 2-4 parts of polyisobutene, 0.5-2 parts of a stabilizer, and 0.3-0.5 part of an antioxygen. The EVA resin, the ethylene-octene copolymer and the polyisobutene are stirred for 10-15 minutes at the temperature of 80-90 DEG C, the stabilizer and the antioxygen are added, stirring is performed for 5-10 minutes, the tackifier is added, the temperature is raised to 110 DEG C, the mixture is stirred for 10-15 minutes, the temperature is reduced to 80 DEG C, and the mixture is extruded through an extruder, and is cut and cooled. The hot melt adhesive formula is reasonable in ingredients and high in stability, and is particularly suitable for the field of furniture processing, the ingredients are environmentally friendly, and the degree of adhesion is high.

Description

technical field [0001] The invention relates to the field of hot-melt adhesives, in particular to a hot-melt adhesive formulation and a manufacturing method thereof. Background technique [0002] Hot melt adhesives are widely used, and different fields have different performance requirements for hot melt adhesives. When used in the field of furniture, in addition to high requirements on the safety, stability and adhesion of hot melt adhesives, it is also required to be green and environmentally friendly, so as to avoid harm to the human body when placed indoors for a long time. The furniture manufacturing field uses a large amount of hot melt adhesives, and cost control is also a scope that needs to be considered. Currently, hot melt adhesives with reasonable composition, high stability, environmentally friendly composition, and high adhesion are rare on the market and need to be developed. Contents of the invention [0003] In order to overcome the shortcomings of the e...
