A kind of polymer resin laminated glass glue and preparation method thereof

Abstract

The invention relates to a polymer resin laminated glass glue, which is made of the following raw materials in weight percentage: 40-65% of polyurethane modified polyester resin, 10-30% of m-benzene unsaturated polyester resin, 5-5% of hardness regulator 10%, viscosity reducing diluent 10~30%, curing agent 0.5~4%, curing accelerator 0.1~3%, anti-ultraviolet agent 0.5~2% and defoamer 1~3%, the preparation method comprises the following steps: Polyurethane modified polyester resin and m-phenylene unsaturated polyester resin are added into the container cylinder and stirred and mixed; then hardness modifier, viscosity reducing diluent, curing accelerator, anti-ultraviolet agent and defoamer are added to the reactor, Start the stir bar at room temperature and stir for a few minutes; add curing agent and mix well. The beneficial effects of the present invention are: it can be fully cured at normal temperature and pressure, and at the same time, the viscosity of the colloid is low, it is easy to release air bubbles, and the process operation on production is simplified and convenient. glue.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a polymer resin laminated glass glue and a preparation method thereof. Background technique [0002] Laminated glass is a composite material in which glass and glass are separated by an intermediate layer and bonded together through treatment. It is generally used for the manufacture of safety glass, bulletproof glass, architectural decorative glass, art glass, etc. After the polymer resin laminated glass glue is cured, it can be used as the middle separation layer. Laminated glass production methods include dry production process and wet production process. The process of curing with glue is called wet process. Polymer resin laminated glass glue can also be called wet glass glue. [0003] The application technical performance of laminated glass requires optical properties (visible light transmittance, visible light reflectance, some products require ultraviolet transmi...

Problems solved by technology

[0005] Although acrylic polymers have good transparency and excellent optical properties, acrylic polymers (such as PMMA) themselves have high hardness and are brittle. After adding plasticizers, the hardness can be reduced, but due to the migration of plasticizers, the product Poor adhesion and decreased transparency during use

The curing process requires ultraviolet light (sunlight) or heating equipment to initiate crosslinking, so the curing process is complicated, quality control is difficult, and production costs are high
