Abstract
The invention discloses a low-temperature hot melt adhesive which is prepared from the following raw materials in percentage by mass: 10-40% of styrene-isoprene-styrene block copolymer (SIS), 10-30% of a tackifier, 5-18% of nitrile-butadiene rubber, 10-40% of polyethylene wax, 0.6-0.1% of an antioxidant, 10-30% of naphthenic oil and 20-30% of resin, wherein the tackifier is rosin resin or petroleum resin; the nitrile-butadiene rubber is powder nitrile-butadiene rubber with acrylonitrile content of 32-35%; the naphthenic oil is KN4010 naphthenic oil; the antioxidant is one or more of an antioxidant B225, an antioxidant 1010, an antioxidant 168, and an antioxidant DLTP, and has outstanding processing stability and long-term protective effect on polyolefin; the polyethylene wax is of an AC8 level, and shows very strong external lubricating property due to an irregular structure and low-viscosity homopolymer. The hot melt adhesive disclosed by the invention has viscosity of less than or equal to 1.5Pa.s at 150 DEG C, and the viscosity fluctuates little under a temperature changing condition, is relatively stable, and is more excellent at -10 DEG C.
Description
technical field [0001] The invention belongs to the field of hot-melt adhesives, in particular to pressure-sensitive adhesives used in low-temperature environments. Background technique [0002] Generally, the hot melt adhesive coated into self-adhesive paper has requirements for acid resistance, alkali resistance, temperature resistance, water resistance, chemical resistance, and aging resistance. Usually, the label paper made of hot melt adhesive can only be labeled when it is above 10 degrees Celsius. When the temperature is low, the hot melt adhesive often has discoloration, viscosity drop or even brittle cracking. Contents of the invention [0003] The invention aims to overcome the defects of the prior art and provide a low-temperature hot-melt adhesive which still has strong adhesive force at minus 10 degrees. [0004] A kind of low temperature hot melt adhesive, the mass composition of raw material is: [0005] Styrene-isoprene-styrene block copolymer (SIS) 10%~4...
