Blending Modified VAE Emulsion

2024-09-30

Vinyl acetate-ethylene copolymer emulsion is a polymer emulsion made of vinyl acetate and ethylene as basic raw materials, referred to as VAE emulsion or EVA emulsion in English. Since its introduction in 1965, it has been widely used in adhesives, building materials, coatings, papermaking, fabric processing, tobacco, packaging and other fields due to its excellent adhesion, permanent flexibility, good acid and alkali resistance and other properties.

In order to improve the performance of VAE emulsion and expand its application range, a lot of fruitful modification research has been done to improve the water resistance, mechanical strength, heat resistance, adhesion, curing speed and other aspects of VAE emulsion. These modification studies are mainly focused on the following directions: additive method, copolymerization method, composite modification method and blending method. Among them, the blending method is a method of physically blending VAE emulsion with one or more polymer solutions or emulsions to form a multi-component system. The properties of the various components of the blending method can complement each other, thereby obtaining new materials with better performance or new properties, reducing costs while potentially expanding the application field of VAE emulsion, allowing VAE emulsion to play a greater application value.

Polymer solutions or polymer emulsions that are often blended with VAE emulsions include: rosin resin, phenolic resin, urea-formaldehyde resin, terpene resin, polyurethane emulsion, acrylic emulsion, styrene-acrylic emulsion, vinyl acetate emulsion, styrene-butadiene emulsion, etc. Since VAE emulsion has good miscibility with a variety of emulsions, blending is the simplest and most direct way to achieve complementary properties of the blended components and obtain new properties.

PVAc emulsion was used to modify VAE emulsion, and at the same time, thickening resin and additives were used to synthesize an adhesive suitable for bonding non-polar plastic materials. The addition of thickening resin significantly improved the bonding strength of the emulsion; the addition of acidic metal salt crosslinking agent improved the water resistance of the system without affecting the stability of the emulsion.

VAE emulsion was modified by blending pure acrylic emulsion, acetic acid acrylic emulsion, silicone acrylic emulsion, styrene acrylic emulsion and VAE emulsion to prepare adhesive. The results show that the VAE emulsion modified by acrylate emulsion has been greatly improved in bonding performance and peel strength. Among them, the adhesive obtained by using acetic acid acrylic emulsion to modify VAE emulsion has the best comprehensive performance, especially the most obvious improvement in high temperature adhesion.
