Problems solved by technology

However, when the above-mentioned hot melt adhesive is used for hot-drilling products, its shear peel strength is low, the tensile strength is not enough, and it is easy to peel off, which cannot meet the requirements of hot-drilling products.
[0004] At present, the hot-melt adhesives used for ironing drills are mainly polyamide hot-melt adhesives and EVA resin hot-melt adhesives. Polyamide hot-melt adhesives have a high pressing temperature and are easy to burn acrylic hot-melt drills. The operation is difficult and the bonding strength is difficult. Meet the requirements

Abstract

The invention provides a hot melt adhesive for an acrylic hot-fix rhinestone. The hot melt adhesive comprises the following components by weight: 10 to 15 parts of EVA resin with the VA content of 28% and the MI of 150 g / 10min, 0 to 35 parts of EVA resin with the VA content of 28% and the MI of 6 g / 10min, 4 to 12 parts of thermoplastic polyurethane with Shore D hardness of 70, 30 to 40 parts of styrene modified C5 petroleum resin, 10 to 20 parts of polyethylene wax, 2 to 6 parts of EBA3427AC and 1 to 2 parts of an antioxidant 1010. The hot melt adhesive for the acrylic hot-fix rhinestone provided by the invention has a hot-press temperature of 115 to 120 DEG C, is not prone to scalding the acrylic hot-fix rhinestone and fabrics, and has peeling strength of no less than 4.0kN / m , thereby having high bonding strength at the same time; meanwhile, the hot melt adhesive has the advantage of good adhesive force with a variety of fabrics and acrylic hot-fix rhinestones, and is an ideal hot melt adhesive for the acrylic hot-fix rhinestone.

Description

technical field [0001] The invention belongs to hot-melt adhesives and a preparation method thereof, in particular to acrylic hot-melt hot-melt adhesives and a preparation method thereof. Background technique [0002] Acrylic hot-melt adhesive is a kind of hot-melt adhesive coated on the back of acrylic hot-melt after heating and melting. Melt glue plays the role of bonding ironing diamonds and clothing fabrics, and is also suitable for various materials of luggage and footwear. The hot melt adhesive is required to have a softening point suitable for hot drilling, high peel strength, and water washing resistance. [0003] For example, CN102703006A discloses a hot-melt adhesive, which specifically relates to a kind of strong adhesive force, fast drying speed, small consumption, good thermal stability, anti-aging, anti-acid and alkali, pollution-free and adaptable to high-speed automatic assembly line production packaging The required hot melt adhesive and its preparation me...
