Description

technical field

[0001] The present invention relates to a hybrid latex comprising polymer particles having a core-shell structure and a method for preparing the same. The invention also relates to the use of said hybrid latex in polymer waterproofing membranes and polymer-modified mortars. Background technique

[0002] Cement-based building materials are the basis of modern architecture and are widely used. However, tensile strength, adhesive strength, fracture toughness, impermeability, corrosion resistance, abrasion resistance, crack resistance, and durability are not desirable due to their porous and brittle nature, so , its application requires significant changes in some fields such as flexible cement-based waterproof membranes, cement-based tile adhesives, waterproof mortars, corrosion-resistant mortars, repair mortars, cement-based primers, and the like. The properties mentioned above can be significantly improved by modification of polymers, especially polymer emul...
