APAO hot melt adhesive and preparing method thereof

Abstract

The invention discloses an APAO hot melt adhesive and a preparing method thereof, which includes the following materials in weight percentage: 10-25% of naphthenic oil, 1-5% of white mineral oil, 20-50% of APAO resin, 1-50% of APP resin, 35-60% of C5 hydrogenization petroleum resin, 0.5-1% of antioxygen 1010, and 0.5% of antiager A. According to the invention, the bonding strength is higher, the working temperature of hot melt adhesive finished product is greatly increased, so that the requirements for bonding technology of textures such as shoe linings, sponge, toe puffs, non-woven fabrics and leather are completely met; besides, the APAO hot melt adhesive has special affinity and bonding force for materials of PE and PP with low surface energy and difficulty in adhesion; a simple and practical blending preparation technology is adopted, and the chemical preparation methods such as crosslinking and copolycondensation of most former polyamide hot melt adhesive are avoided, so that the technological process is greatly simplified, the energy consumption is reduced, and better economic benefit and industrial production prospect are achieved.

Description

[0001] technical field [0002] The invention relates to the field of adhesive products, in particular to an APAO hot melt adhesive and a preparation method thereof. [0003] Background technique [0004] Hot melt adhesives are required for the bonding of shoe linings, sponges, Gangbao, labels, non-woven fabrics, leather and other materials. However, the current hot melt adhesive has the following defects: [0005] Existing hot melt adhesives have high melt viscosity, poor toughness at low temperature, poor low temperature performance, inconvenient use, and limited application range. Some have poor high temperature resistance, poor temperature rise performance, low bonding strength, and limited application range. [0006] Existing hot melt adhesives have the defects of insufficient thermal viscosity and permeability. EVA hot-melt adhesives have good low-temperature performance and suitable melt viscosity. However, the defect of EVA adhesive is poor high temperature resi...
