The surface mortar used in EPS decorative lines is generally ordinary and cheap exterior wall insulation anti-cracking mortar, and exterior wall thermal insulation bonding mortar, the ordinary exterior wall anti-cracking mortar anti-cracking effect is not good, the aggregate is quartz sand is relatively coarse, resulting in an unsmooth surface, less cement composition, resulting in relatively low hardness, and does not have hydrophobicity, ordinary exterior wall insulation adhesive mortar adhesion is insufficient, hardness is not high enough.
The two production formulas of EPS mold mortar are as follows:
1.An EPS decorative line high-strength bonding mortar, which is characterized by comprising the following weight components: 420 parts Portland cement, 30 parts of redispersible latex powder, 3 parts of hydroxypropyl methylcellulose, 507 parts of 40-70 mesh quartz sand, and 40 parts of silica fume.
2.- A kind of EPS decorative line high-strength anti-crack mortar, including the following weight components: it is characterized by, 400 parts of silicate hydrochloric acid cement, 518 parts of 80-120 mesh quartz sand, 40 parts of silica fume, 30 parts of redispersible latex powder, 2 parts of hydroxypropyl methylcellulose, 3 parts of polypropylene anti-crack fiber, 5 parts of wood fiber, and 2 parts of hydrophobic agent.
EPS decorative lines high-strength bonding and anti-cracking mortar, including high-strength bonding mortar, including: Portland cement, redispersible latex powder, hydroxypropyl methylcellulose, 40-70 mesh quartz sand, silica fume;High-strength anti-crack mortar, including: silica hydrochloride cement, 80-120 mesh quartz sand, silica fume, redispersible polymer powder, hydroxypropyl methylcellulose, polypropylene anti-crack fiber, wood fiber, water repellent agent. This process improves the bonding and crack resistance strength and surface smoothness, solves the problem that the surface of the EPS decorative line is not smooth, the surface strength is not high, and the product is not hydrophobic in the prior art, so that the bond between the EPS decorative line and the wall is more firm.
