Preparation and performance study of polymer cement waterproof coatings
The polymer cement waterproof coating was prepared with acrylic acid lotion as the base liquid,cement,heavy cal-cium and river sand as the powder,and a variety of additives.Explored the effects of different liquid powder ratios on the tensile performance,low-temperature flexibility,water resistance,and bonding strength of polymer cement waterproof coatings,and determined the optimal liquid powder ratio.At the same time,the durability of the coating with the optimal liquid powder ratio formula was explored through immersion treatment,alkali treatment,and heat treatment.The experimental results show that the JS waterproof coat-ing prepared with a coating liquid to powder ratio of 1∶1.2 has the best performance.After immersion treatment,alkali treatment,and heat treatment at this ratio,the tensile performance and bonding strength of the coating meet the performance parameters requirements of Type Ⅱ coating in the standard GB/T23445-2009"Polymer cement waterproof coatings",demonstrating good durability.
