Abstract

The invention discloses a process for preparing hot-melt adhesives, and specifically relates to the field of polymer materials, wherein the main materials used include the following raw materials in parts by weight: 40-50 parts of natural rubber, 30-40 parts of nitrile neoprene Parts, 10-14 parts of isoprene rubber, 6-10 parts of modifiers, said modifiers include tackifiers, viscosity regulators and phenolic antioxidants, said tackifiers, viscosity modifiers and phenols The ratio between the antioxidants is 5-6: 2-2.5: 0.2-0.3, and the auxiliary material includes 60-80 parts of dissolved oil in terms of parts by weight, and the dissolved oil is set to any one of naphthenic oil and rubber oil. A sort of. The invention uses natural rubber, nitrile neoprene rubber, isoprene rubber and modifiers as raw materials, and adopts the mutual absorption between dissolved oil and raw materials, which can completely solve the problem of waste discharge difficulty and broken waste discharge, and at the same time, the compatibility of materials is better. Well, the transparency is higher, and the fluidity and high temperature resistance of the glue are also improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, and more specifically, the invention relates to a process for preparing hot-melt adhesives. Background technique [0002] Hot melt adhesive is a kind of plastic adhesive, which is in a solid state at room temperature, and can be quickly bonded after heating and melting. Hot-melt adhesives have characteristics: fast bonding usually takes only tens of seconds or even a few seconds from glue application to cooling and bonding; a wide range of bonding is suitable for many materials, even for recognized difficult-to-bond materials (such as polyolefin, Waxed paper, carbon paper, etc.) can also be bonded, especially the joints bonded with hot melt adhesive, which can withstand more than 105-106 times of bending without cracking; can be heated repeatedly and bonded multiple times; stable performance and convenient for storage and transportation; The low-cost hot-melt adhesive has no solvent co...
