Coating classification: waterborne acrylic coating

Core tip: acrylic waterborne wood paint is an early and still widely used variety Since the 1970s, acrylic building latex paint began to be widely promoted, water-based acrylic wood paint also appeared in the market Acrylic emulsion was polymerized by vinyl monomers based on acrylate monomers In the polymerization process, emulsifiers, stabilizers, pH regulators and other auxiliaries were added, and the system was quite complex By using different monomers of soft and hard, adjusting dosage and changing feeding way, the distribution of soft and hard segments of polymer molecules in emulsion particles can be controlled, so that different vitrification can be obtained Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Home of coatings: acrylic waterborne wood paint is an early and still widely used variety Since the 1970s, acrylic building latex paint began to be widely promoted, water-based acrylic wood paint also appeared in the market Acrylic emulsion was polymerized by vinyl monomers based on acrylate monomers In the polymerization process, emulsifiers, stabilizers, pH regulators and other auxiliaries were added, and the system was quite complex Using soft and hard monomers, adjusting dosage and changing feeding way, the distribution of soft and hard segments of polymer molecules in emulsion particles can be controlled, so that different emulsion temperature (Tg) or different minimum film temperature (MFFT) emulsion can be obtained The emulsifier used in polymerization can be anionic or non-ionic or cationic The corresponding emulsion and the paint can also be called anionic, non-ionic or cationic type Acrylic monomer is polymerized only with pure acrylic emulsion, and the paint is called pure acrylic waterborne paint When polymerization, other vinyl monomers can be added to modify the emulsion, for example, adding styrene to improve the hardness and reduce the cost of the paint film; introducing fluorinated and silicon containing monomers to improve the surface properties of the paint film, reducing the surface free energy of the film, improving the hydrophobicity and stain resistance Thus, the water-based coatings such as styrene acrylic, fluorocarbon and silicon acrylic are produced The paint film made of acrylic emulsion has good weatherability and is not easy to yellowing, high hardness and gloss But its main disadvantage is poor adhesion resistance, easy to appear hot sticky cold brittle phenomenon, high hardness, low temperature film forming is not good, it is difficult to carry out coating construction in winter The properties of acrylic emulsion were further improved and improved by self crosslinking polymerization, soap free polymerization and core-shell polymerization In particular, core-shell technology was used to make emulsion particles into hard core soft shell or soft core hard shell structure, or even multi-layer structure of soft and hard phase, so as to meet the needs of different construction and application conditions Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
