The hardness and softness of the water-based acrylic resin can be adjusted according to specific needs, but it is usually biased towards the harder side.

First, the characteristics and application of water-based acrylic resin

Water-based acrylic resin is an environmentally friendly water-based resin, with non-toxic, easy to clean, dry fast and other characteristics, widely used in furniture, packaging, building materials, auto parts and other fields.

Second, the factors affecting the hardness of water-based acrylic resin

The hardness and softness of water-based acrylic resins are affected by many factors, mainly including the characteristics of the resin itself, crosslinking agents, additives, solution concentration and external environmental factors such as light and temperature.

1. Resin characteristics: the degree of polymerization, molecular weight and distribution of acrylic monomers directly affect the molecular structure and strength of the resin, thus affecting the softness and hardness.

2. Crosslinking agents and auxiliaries: the types of crosslinking agents and auxiliaries, the amount of addition and reaction conditions will also affect the hardness and softness of the resin, such as hardness agents can increase the hardness of the resin, and softness agents can reduce the hardness of the resin.

3. Solution concentration: The change of solution concentration will affect the viscosity and drying speed of the resin, which will have a certain impact on the softness and hardness.

4. External environmental factors: the external environment such as light and temperature will also affect the softness and hardness of water-based acrylic resin.

Third, adjust the hardness of water-based acrylic resin according to demand

Since the softness and hardness of water-based acrylic resin are affected by many factors, the softness and hardness of the resin can be changed by adjusting these factors.

1. Add different kinds of crosslinking agents or auxiliaries

According to the need, different kinds of crosslinking agents or auxiliaries can be added appropriately to adjust the hardness and softness of the resin. For example, hardness agents can increase the hardness of the resin, and softness agents can reduce the hardness of the resin.

2. Change the solution concentration of the resin

Changing the concentration of the resin solution can also change the hardness of the resin, if a harder resin is needed, the solution concentration can be increased; If a softer resin is required, the solution concentration can be reduced.

3. Control heating time and temperature

The heating time and temperature of the resin will affect its cross-linking degree and molecular structure, which will affect the softness and hardness of the resin. Therefore, controlling the heating time and temperature is also an important method to adjust the softness and hardness of the resin.

Fourth. Conclusion

En general, las resinas acrílicas a base de agua suelen inclinarse hacia el lado más duro, pero cambiando el agente reticulante, los aditivos, la concentración de la solución y controlando el tiempo y la temperatura de calentamiento, la suavidad y la dureza también se pueden ajustar según las necesidades específicas. Para diferentes campos de aplicación, es necesario elegir resinas acrílicas a base de agua con diferente dureza y suavidad según las necesidades específicas.
