The invention relates to an antibacterial low-melting-point
hot melt adhesive. The antibacterial low-melting-point
hot melt adhesive is processed from the following raw materials in parts by weight: 40-80 parts of a
polyester hot melt adhesive, 20-30 parts of
polyamide resin, 3-8 parts of paraffin, 0.5-1 part of an
antioxidant 164 and 0.5-1 part of an inorganic
antibacterial agent. A preparation method of the antibacterial low-melting-point
hot melt adhesive comprises the following steps: uniformly mixing the
polyester hot melt adhesive, the
polyamide resin, the paraffin, the
antioxidant and the inorganic
antibacterial agent according to the formula ratio, adding the mixture into a screw extruder granulator, carrying out
melt blending extrusion, cooling and granulating the extruded mixture, and carrying out
vacuum drying on the aggregates to remove
moisture, so as to obtain the antibacterial low-melting-point
hot melt adhesive. By mixing the low-melting-point
polyester hot melt adhesive with the
polyamide resin, the paraffin, the
antioxidant and the inorganic
antibacterial agent, the prepared hot melt adhesive is stable in binding power, high in curing speed and convenient to use and does not easily
mildew, the environmental influence is low, and particularly, the curing rate is prior to that of the hot melt adhesive in the prior art in a low-temperature environment; the production efficiency is greatly improved, the cooling
curing time is substantially shortened after the
coating of the hot melt adhesive, and the
coating efficiency is remarkably improved.
