emulsion acrylic resin and water soluble acrylic resin where is the difference?

In fact, the water-based resin according to the appearance of points, can be divided into water emulsion type, water dispersion type and water-soluble. Many people think that this is the same resin, but it is not, not only the appearance is different, but also the use and characteristics are very different. So, next, by the small make up to give you a brief introduction, emulsion acrylic resin and water-soluble acrylic resin where the difference.

at present, there are some vague concepts in the society, and the water-based resin is generally called water-soluble resin. Aqueous acrylic resins are generally classified into aqueous emulsion type acrylic resins and aqueous solid acrylic resins. Water emulsion type resin is prepared by adding emulsifier. Water-soluble resin is achieved by self-emulsifying property with hydrophilic groups on the polymer chain. Water dispersion type resin is between the two, the amount of added emulsifier and the hydrophilic group with insufficient, to rely on external forced power, such as high-speed stirring dispersion, or ultrasonic to achieve water dispersibility. Therefore, its particle size and transparency are also between the first two. Water emulsion type oily weight, generally milky white. The water-soluble resin is transparent, and is a true solution in the form of molecular dispersion, which belongs to a nano-scale dispersion state.

acrylic resin has excellent light resistance, weather resistance, no yellowing, long-term maintain high gloss performance, and with other monomers and polymers for grafting, copolymerization and blending modification, to obtain excellent water resistance, chemical resistance, anti-pollution and corrosion resistance, widely used in coatings, adhesives, inks, textile and leather auxiliaries and many other fields.

water emulsion type acrylic resin and water-soluble (including water dispersion) acrylic resin structure is different, different performance, use is naturally different. Water emulsion type resin partial oil, completely rely on surfactant, that is, emulsifier to wrap it up, can be dispersed in water. Therefore, when they are used in conjunction with other resins and additives, special care should be taken that this coat is not stripped by temperature, stirring power, or by adsorption and reaction of external substances, and demulsification flocculation. The water-soluble resin contains many polar groups in the molecular chain, such as hydroxyl group, carboxyl group, sulfonic acid group, amino group, amide group, methylol group, ethylene oxide group, etc. Therefore, the aqueous dispersion and the water-soluble resin have a certain polymer surface activity. According to the proportion and distribution of hydrophilic groups and hydrophobic groups, the surface activity is different, such as wetting and dispersing, emulsifying and defoaming, osmotic adsorption and so on.

according to the structural properties of these water-soluble resins to choose auxiliaries and with the conditions, can make them in coatings, adhesives, textile and leather auxiliaries to find the ideal application. The application range of water emulsion resin is narrow (5-40 degrees), beyond this range, it is possible to break the emulsion. The water-soluble resin has a wide operating temperature, can withstand the test of freezing and thawing and heat resistance, and can obtain better performance and larger application fields than water emulsion. Such as our development of water-based wood paint can be resistant to boiling water, soaked in 68-72 degrees of water, 95% of the medical alcohol and 4. 5% iodine salt solution in 30 days, the film intact. The hardness reaches 2H, the impact resistance is 50cm, the paint film is plump and smooth, and can be comparable to solvent-based PU paint.
