Factors affecting the viscosity of VAE emulsion

, ,

VAE (ethylene-vinyl acetate copolymer) emulsion viscosity is an important quality indicator and has a significant impact on product mass transfer, heat transfer, fluid flow, emulsion stability and emulsion transportation. Monomer ratio, polymerization temperature, initiator, emulsifier system optimization, electrolyte additives, and storage conditions are all factors that affect the viscosity of VAE emulsion.

 

1. Monomer ratio

The selection and proportion of monomers directly affect the viscosity and other properties of VAE emulsion. The ratio of ethylene to vinyl acetate (VAc) is particularly critical. Generally speaking, VAE emulsions with a VAc content of 70% to 95% have higher viscosity. Increased VAc content will increase the flexibility and elasticity of the emulsion, and will also increase the viscosity of the emulsion.

 

2.Polymerization temperature control

Polymerization temperature is another important factor affecting the viscosity of VAE emulsion. Changes in temperature will affect the rate of free radical generation and the rate of polymerization. Generally speaking, within a suitable temperature range, an increase in temperature will speed up the polymerization reaction, causing the latex particles in the emulsion to grow rapidly, resulting in an increase in viscosity. However, too high a temperature may cause the emulsion to gel, affecting its quality and stability.

 

3.Initiator

The amount and type of initiator have a significant impact on the viscosity of VAE emulsions. Initiators mainly affect the rate of polymerization. When the amount of initiator is large, the polymerization reaction is fast, the number of generated latex particles increases, and the viscosity of the emulsion increases. However, excessive initiator may cause the reaction to be too fast and difficult to control, resulting in reduced emulsion performance. Different types of initiators generate different types of free radicals during the reaction and have different effects on the viscosity of the emulsion.

 

4. Emulsifier system optimization

The selection and dosage of emulsifier are crucial to the stability and viscosity of VAE emulsion. The main function of emulsifier is to reduce the surface tension of emulsion and promote monomer dispersion and emulsion formation. Appropriate emulsifier concentration and anionic/nonionic emulsifier ratio can improve the stability of the emulsion and also affect the viscosity of the emulsion. The degree of polymerization and alcoholysis of protective colloids such as PVA (polyvinyl alcohol) also significantly affect the viscosity of the emulsion. The higher the degree of polymerization of PVA, the greater the viscosity of the emulsion; the higher the degree of alcoholysis, the lower the viscosity of the emulsion.

 

5.Electrolyte additives

The addition of electrolyte additives can affect the viscosity and stability of VAE emulsions. Some electrolyte additives can compress the electric double layer of latex particles and reduce the electrostatic repulsion between latex particles, thereby increasing the viscosity of the emulsion. However, excessive amounts of electrolyte additives may cause aggregation in the emulsion, affecting its performance.

 

The factors that affect the viscosity of VAE emulsions include reaction time and rate, PH value, storage conditions and stability. In actual production and application, these factors need to be reasonably adjusted according to specific needs and conditions to obtain VAE emulsion products with excellent performance.

Adhesives of VAE Emulsion mixed with additives

, ,

VAE emulsion is a water dispersion chemical that avoids the environmental impact of solvents and unsafe hazards. Ethylene gives polymers a softness that is permanent and impervious to the environment and climate. VAE dispersions can not only be used as excellent adhesives for paper, wood, plastics, synthetic fabrics, etc., but also can be easily mixed with thickeners, surfactants, PH regulators, plasticizers, solvents, fillers and other ingredients to make adhesives for various specific use.

 

1. Add thickener

The water-soluble polymer thickener can increase the viscosity of the continuous phase between dispersed polymer particles, thereby increasing the viscosity of VAE emulsions. Sodium polyacrylate is an effective thickening agent for VAE emulsions. When the addition amount of thickener is less than 1%, it has little effect on the stripping strength. When 7% is added, the bond strength is significantly reduced.


Carboxylic butylbenzene emulsion can significantly increase the viscosity of VAE emulsion, and improve the bonding strength of PVC, PP and other substrates. However, attention should be paid to controlling the amount of addition to prevent the viscosity from being too high.

 

2. Add surfactants

The addition of alkyl polyoxyethylene ether and other surfactants to VAE emulsions can improve the wettability of surfaces that are difficult to wet (such as PVC films, etc.). The effective concentration is 0.1-1.0% parts surfactant per 100 parts emulsion.
Adhesives manufactured with VAE emulsions generally do not require the addition of defoamer. In case of foam, add 0.1 ~ 0.2% defoamer.

 

3. Add PH regulator

VAE emulsions are generally stable in the PH range of 3.0 to 8.5. If the PH of the mixture containing VAE emulsions is adjusted below 3.0, it results in an excessively high viscosity and is hydrolyzed more rapidly in the wet state, resulting in a lower PH. When the VAE emulsion is mixed with a dispersion solvent with a completely different PH (for example, PH 9.0), the PH of the VAE emulsion should first be adjusted above 7 with an alkaline substance. To minimize the effects caused by the difference in PH. Ammonia and sodium hydroxide are commonly used PH regulators for VAE emulsions.

 

4. Add plasticizer and solvent

The addition of plasticizers can reduce the cost of formulations. The addition of plasticizers and solvents can also improve the performance of substrates that are difficult to bond. Four plasticizers, dibutyl phthalate, butyl phenyl phthalate, dipropylene glycol phthalate and dioctyl phthalate, were added at 15% concentration to thicken CW40-705.

 

5. Add stuffing

In VAE dispersion-based adhesives, low-cost fillers such as clay and calcium carbonate can be added as fillers or fillers. The viscosity of emulsion can be increased by adding dry filler. First dispersed with water, then a large number of fillers can be added without making the workable viscosity too high. CW40-707 can accept more fillers than other varieties.

 

6. Wet strength additives

The water resistance of VAE emulsions generally meets the requirements. Where improvement is needed, dialdehyde, water-soluble urine aldehyde resin (UF), melamine resin (MF) or phenolic resin can be added. Excellent water resistance can be achieved by heating curing.
