Coating classification: special compound thixotropic thickener for stone paint

Core tip: Introduction: the special compound thixotropic thickener for stone paint is a kind of associated thickener for flying sand phenomenon during spraying of stone paint Its thickening mechanism is that hydrophobic groups gather due to hydrophobic action, which makes macromolecular chains associate with each other within and between molecules, which greatly affects the rheological properties of aqueous solutions Above the critical associating concentration, a supramolecular structure dominated by intermolecular association is formed, which increases the volume of fluid mechanics, so it has better thickening property and is a new generation of thickener Because there are two or more lipophilic groups in the water-soluble chain with low molecular weight of the associated thickener, there is a surface in the water Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Coating home news: Introduction: the special composite thixotropic thickener for real stone paint is a kind of associated thickener aiming at the flying sand phenomenon when spraying real stone paint Its thickening mechanism is that hydrophobic groups gather due to hydrophobic action, which makes macromolecular chains associate with each other within and between molecules, which greatly affects the rheological properties of aqueous solutions Above the critical associating concentration, a supramolecular structure dominated by intermolecular association is formed, which increases the volume of fluid mechanics, so it has better thickening property and is a new generation of thickener Because there are two or more lipophilic groups in the water-soluble chain with low molecular weight of the associated thickener, there is surfactant behavior in water, which can form micelles However, the two lipophilic groups in the molecule are not necessarily in the same micelle, so they are linked to form a structure The affinity groups of the associating thickeners can adsorb emulsion particles and pigment particles, which enhance the structure Moreover, the particles bridged by the thickener macromolecules form a physical network structure, which can be destroyed gradually in the shear field, so the flow properties of the system can be controlled Such association breaks off at high shear rate, reduces viscosity, forms again after shear removal, and recovers viscosity, but the formation of association takes time, so the recovery of viscosity is not as fast as cellulose, thus giving a certain flow time, which is conducive to leveling and lubrication Product features: the thickener is a kind of light yellow powder, with excellent dispersion, suspension, thickening, thixotropy, water retention and other characteristics The product itself is alkali resistant, does not participate in the system chemical reaction, does not produce mildew, and has certain hydrophobicity It can obviously improve the phenomenon of flying sand during the spraying of real stone paint; reduce the amount of cellulose, improve the water resistance of paint, prevent mildew and whitening; it can significantly improve the construction, improve the suspension, do not separate water and prevent precipitation It can be used in stone paint, rock paint, sand paint and other products, so that the product has good lubricity when pumping, mixing, scraping and spraying, and can reduce the amount of organic thickener by 20% - 50% 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,
