As the core additive of insulation mortar, RDP enhances its comprehensive performance in all aspects through a unique film-forming mechanism. After being mixed with water, the RDPparticles re-disperse and hydrate to form a continuous polymer film, which constructs an interpenetrating network structure with the hydrated products of cement, optimizing the mortar performance at the micro level.
As the core additive of insulation mortar, RDP enhances its comprehensive performance in all aspects through a unique film-forming mechanism. After being mixed with water, the RDPparticles re-disperse and hydrate to form a continuous polymer film, which constructs an interpenetrating network structure with the hydrated products of cement, optimizing the mortar performance at the micro level.
Its performance enhancement effect on thermal insulation mortar is particularly significant:
Firstly, it enhances the bonding strength. The polymer film can penetrate the pores of the substrate to form mechanical interlocking, significantly improving the adhesion to substrates such as polystyrene boards and concrete, and reducing the risk of hollowing and detachment;
Secondly, it improves flexibility and crack resistance. The flexible polymer network can absorb the stress generated by temperature changes and structural settlement, breaking the brittle limitations of ordinary mortar and effectively inhibiting shrinkage cracks;
Thirdly, to enhance water repellency and durability, the polymer film seals the capillary pores, significantly reducing water absorption, improving impermeability and weather resistance, and resisting freeze-thaw cycles and moisture erosion;
Fourthly, optimizing construction performance can improve the fluidity and water retention of freshly mixed mortar, ensuring smooth construction without affecting the water vapor permeability of the mortar.
By reasonably incorporating redispersible emulsion powder, the contradiction between the strength and thermal insulation properties of traditional insulation mortar can be synergistically resolved, allowing the mortar to exhibit both excellent thermal insulation and reliable mechanical properties, providing lasting protection for building energy efficiency.
