The invention discloses an anchor-free EPS decorative component
system. A groove is formed in the bottom surface of an EPS decorative component
polystyrene board base body, during assembling, reinforcing anchors are not required, the working period is shortened, the cost is reduced, furthermore, a cold bridge formed by holes caused by nailing is avoided, and meanwhile, the quality problem caused by rusting of the anchors is avoided; a groove and a protrusion are arranged at the two ends of an EPS decorative component, firm attachment is implemented during
lap joint, and cracks of a finish coatare avoided. Special binding
mortar for the EPS decorative component has the characteristics of good initial mobility, high early strength, good permeability and high size stability, development of later strength is not affected while high early strength can be ensured, and by addition of a water retaining agent, the circumstance that the initial mobility of the
mortar is reduced due to increasing of stickiness while full water-retaining property can be ensured; by addition of a surfactant, the
surface tension of
mortar is reduced, and permeability is enhanced; and by addition of a thixotropic
lubricant, the mortar has a good application property and good sagging resistance.
