Caulking cement for prestrain wallboards
The invention provides caulking cement for prestrain wallboards, which comprises the following components: cement, fine river sand, HPMC (hydroxy propyl methyl cellulose), a UEA expanding agent, a lime expanding agent, aluminum powder, and acrylic emulsion. The caulking cement for prestrain wallboards is convenient for construction, can produce certain expansion in the processes of construction and hardening, and a produced expansion applied force can compensate shrinkage stress caused by wallboard shrinkage, thereby reducing the probability of crack occurrence; the caulking cement is high in bonding strength, and bonded firmly between walls; and the compressive strength of the caulking cement is moderate, so that the brittleness of materials is correspondingly reduced, therefore, the caulking cement is also favorable for avoiding cracking.
