Waterproof weatherability polyurethane glass cement

Abstract

The invention discloses a waterproof weatherability polyurethane glass cement, which comprises following raw materials in parts by weight: 70 to 100 parts of polyurethane prepolymer, 10 to 25 parts ofpolyester resin, 5 to 12 parts of liquid nitrile rubber, 3 to 10 parts of chloroprene rubber, 1 to 5 parts of sodium monofluorophosphate, 2 to 5 parts of hexafluorobisphenol A, 1 to 5 parts of 1-allyl-3-methylimidazolium chloride, 2 to 5 parts of graphene, 2 to 10 parts of montmorillonite, 2 to 10 parts of molecular sieve, 2 to 5 parts of titanium dioxide, 3 to 10 parts of silicon carbide, 0.3 to2 parts of 3-isocyanatopropyl triethoxysilane, 0.5 to 3 parts of 1H, 1H, 9H-hexadecafluorononanol, 0.5 to 2 parts of 8-hydroxyquinoline, and 0.2 to 0.5 part of methyl ethyl ketone peroxide. The provided waterproof weatherability polyurethane glass cement has the advantages of high boding strength, excellent weatherability, good waterproof performance, and long service life.

Description

technical field [0001] The invention relates to the technical field of glass glue, in particular to a water-resistant and weather-resistant polyurethane glass glue. Background technique [0002] Glass glue is a common name for glass adhesive. It is a multi-purpose functional material with both bonding and sealing properties. The main types are polyurethane, polysulfide, silicone, acrylic, styrene-butadiene rubber, butyl rubber, asphalt and oily embedded seam glue etc. [0003] Polyurethane glass glue has high strength, tear resistance, soft wear resistance, puncture resistance, oil resistance and medium corrosion resistance. It has been widely used in rail vehicles, automobiles, ships and other windshields, side windows and base iron plates and aluminum plates. Bonding and sealing, but the existing polyurethane glass glue has poor water resistance and weather resistance, and is prone to yellowing and cracking when used outdoors or in a water environment, which seriously lim...

[0003] Polyurethane glass glue has high strength, tear resistance, soft wear resistance, puncture resistance, oil resistance and medium corrosion resistance. It has been widely used in rail vehicles, automobiles, ships and other windshields, side windows and base iron plates and aluminum plates. Bonding and sealing, but the existing polyurethane glass glue has poor water resistance and weather resistance, and it is prone to yellowing and cracking when used outdoors or in a water environment, which seriously limits its application
