Abstract

The invention discloses a formula of an environment-friendly particle hot-melt type pressure-sensitive adhesive. The hot metal adhesive is prepared from the following components in parts by weight: 5-8 parts of polystyrene-polyisoprene-polystyrene segmented copolymer, 5-8 parts of styrene-ethylene / butadiene-styrol copolymer, 5-10 parts of ethylene / vinyl acetate copolymerized resin, 30-40 parts of a softener, 0.5-1 parts of an antioxidant, 53-68 parts of a thickening agent, and 2-5 parts of polyisobutene. The invention further provides a method for preparing the environment-friendly particle hot-melt type pressure-sensitive adhesive. According to the formula and the preparation method disclosed by the invention, the particle hot-melt type pressure-sensitive adhesive is prepared by mixing a reproducible naturally synthesized epoxy plant oil as a raw material, synthetic rubber and resin as well as rubber oil, so that the problems that in the current pressure-sensitive adhesive industry, most of the raw materials cannot be recycled and toxic reagents are added in the process can be solved; and the product is environment-friendly, safe and harmless, easy to adhere, low in possibility to remove and non-destructive while being peeled off, and can be widely applied to the fields of sanitary material, medical treatment and the like.

Description

technical field [0001] The invention relates to the field of hot-melt adhesives, in particular to a formulation and a preparation method of a green environmental protection granular hot-melt pressure-sensitive adhesive. Background technique [0002] Most of the solvents added in the traditional hot melt adhesive production process at home and abroad are toxic reagents, which are harmful to the environment and human body. Hot-melt pressure-sensitive adhesives are solvent-free, more conducive to environmental protection and safe production, high production efficiency, and relatively low production costs, so countries around the world are vigorously developing hot-melt pressure-sensitive adhesives. Hot-melt pressure-sensitive adhesives are widely used in packaging and encapsulation of various products, medical adhesives, and disposable sanitary products. The needs of sustainable development of human beings; and the existing production process requires a relatively large site, ...
