Problems solved by technology

However, acrylate emulsions have problems such as drying, low-temperature adhesion, trace residual gas, and waste water treatment. With the enhancement of people's environmental awareness and the high-speed operation requirements of automated production lines, the proportion of hot-melt pressure-sensitive adhesives is increasing. Big
Due to raw materials, the research and production of hot-melt pressure-sensitive adhesives in my country started relatively late. In 1992, Yueyang Petrochemical started the development of SIS, and realized the first industrialization of domestic SIS in 1997. At present, hot-melt pressure-sensitive adhesives produced by some domestic enterprises It is mainly made of SIS as the main polymer, rosin resin as the tackifying resin, and plasticizers and antioxidants. This system can meet the use under most conditions, but the low temperature resistance is relatively poor, especially in cold winter in the north

Abstract

The invention discloses a high / low-temperature-resistant high / low-temperature general-purpose hot-melt pressure-sensitive adhesive and a preparation method thereof. In order to overcome the technical defects, the invention provides a high-viscosity-strength high / low-temperature-resistant high / low-temperature general-purpose hot-melt pressure-sensitive adhesive and a preparation method thereof. The general-purpose hot-melt pressure-sensitive adhesive comprises 5-10% of polystyrene-isoprene-styrene copolymer (SIS), 5-10% of naphthenic oil, white oil or mixture thereof, 5-10% of amorphous alpha-olefin copolymer 1, 5-10% of amorphous alpha-olefin copolymer 2, 15-20% of amorphous alpha-olefin copolymer 3, 20-30% of C5 petroleum resin, 5-10% of terpene resin, 0-5% of liquid terpene resin, 5-10% of PB (polybutadiene) and 0.5-1% of antioxidant. The high / low-temperature general-purpose hot-melt pressure-sensitive adhesive has the advantages of stable performance, favorable weather resistance, favorable viscosity strength, low cost, high viscosity, wide application range and the like, is free from the influence of the regional temperature, and is stable in all seasons.

Description

technical field [0001] The invention relates to an adhesive, in particular to a low-temperature and high-temperature-resistant general-purpose hot-melt pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] At present, the main varieties of pressure-sensitive adhesives in my country are: acrylate pressure-sensitive adhesives, rubber-type pressure-sensitive adhesives and hot-melt pressure-sensitive adhesives. Acrylic pressure-sensitive adhesives are mainly emulsion type, accounting for more than 65% of the total pressure-sensitive adhesives. However, acrylate emulsions have problems such as drying, low-temperature adhesion, trace residual gas, and waste water treatment. With the enhancement of people's environmental awareness and the high-speed operation requirements of automated production lines, the proportion of hot-melt pressure-sensitive adhesives is increasing. big. Due to raw materials, the research and production of hot-melt pres...
