Reinforcing agent for bonding bricks
The invention discloses a reinforcing agent for bonding bricks. The reinforcing agent is prepared from a powder component and a liquid component, which are mixed evenly at the ratio of 2 to 1 in use, wherein the powder component is prepared from the following raw materials: 30%-45% of 42.5 ordinary portland cement, 51.5%-68.8% of 30-60mesh quartz sand, 1%-3% of redispersible powder VAE, and 0.2%-0.5% of hydroxypropyl methyl cellulose ether with the viscosity being 40000/mPa.s; and the liquid component is prepared from the following raw materials: 40%-60% of acrylic emulsion and 40%-60% of water. The reinforcing agent is coated on the back surface of each brick, and then is dried, and the bricks are pasted by adopting a cement-based adhesive. According to the reinforcing agent disclosed by the invention, the tensile adhesive strength between the adhesive and the bricks is improved; the situations of hollowing and dropping of the bricks after being pasted are reduced; and the bricks are relatively firm and safe to paste.
