Description

technical field

[0001] The invention relates to an acrylate emulsion and a preparation method thereof, in particular to a high-hardness acrylic acid emulsion with high temperature resistance and yellowing resistance and a preparation method thereof. Background technique

[0002] Spray-bonded cotton is a non-woven fabric that is widely used at present. Its principle is to spray the adhesive on both sides of the fluffy fiber layer, because there is a certain pressure when spraying, and combined with the suction force when the lower part of the fiber layer is vacuum-absorbed. , so the adhesive can also penetrate into the inside of the fiber layer, and the fiber layer after spraying the adhesive is then dried and cured, so that the intersection points between the fibers are bonded, and the fibers that are not bonded to each other still remain Considerable degrees of freedom. Because of its fluffy, high compression resilience, resistance to dry and wet washing, and light weigh...
