Problems solved by technology

Polyurethane glass glue has the advantages of high strength, tear resistance, soft wear resistance, puncture resistance, oil resistance and medium corrosion resistance, and is widely used. However, the existing polyurethane glass glue has poor weather resistance and poor antibacterial performance. When used in a water environment, yellowing, cracking, blackening, and sticky surface are easy to occur, which limits its application

Abstract

The invention discloses a weatherability polyurethane glass cement containing silicon dioxide. The glass cement comprises following raw materials in parts by weight: 30 to 60 parts of polyurethane prepolymer, 3 to 10 parts of acrylic resin, 1 to 5 parts of polyvinylidene fluoride resin, 5 to 12 parts of dioctyl phthalate, 3 to 11 parts of diisodecyl phthalate, 10 to 25 parts of sericite powder, 5to 13 parts of silicon dioxide, 2 to 10 parts of calcium oxide, 3 to 11 parts of hollow glass bead, 1 to 6 parts of calcined kaolin, 0.1 to 0.5 part of p-toluenesulfonyl isocyanate, 0.1 to 0.5 part ofantioxidant, 0.1 to 0.5 part of UV absorbent, 2 to 3.5 parts of silane coupling agent, and 0.1 to 0.6 part of catalyst. The provided weatherability polyurethane glass cement containing silicon dioxide has the advantages of high bonding strength, excellent heatproof property, good weatherability, bacterium resistance, and mildew resistance.

Description

technical field [0001] The invention relates to the technical field of glass glue, in particular to a silicon dioxide-containing weather-resistant polyurethane glass glue. Background technique [0002] Glass glue is a kind of adhesive commonly used in households, mainly including silicone glue and polyurethane glue. Polyurethane glass glue has the advantages of high strength, tear resistance, soft wear resistance, puncture resistance, oil resistance and medium corrosion resistance, and is widely used. However, the existing polyurethane glass glue has poor weather resistance and poor antibacterial performance. When used in a water environment, it is prone to yellowing, cracking, blackening, and the surface is easy to stick, which limits its application. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a weather-resistant polyurethane glass glue containing silicon dioxide, which has high bonding ...
