▎ 摘　　要

NOVELTY - Adhesive mortar comprises a component A including 35-50 pts. wt. cement, 0.2-0.5 pts. wt. cellulose ether and 45-70 pts. wt. quartz sand. The component B including 30-60 pts. wt. modified acrylic acid emulsion, 3-5 pts. wt. hydrophilic group modified graphene dispersion liquid and 5-10 pts. wt. auxiliary agent. The glass transition temperature of the modified acrylic emulsion is not less than 0 degrees C. The amount of hydrophilic groups in the hydrophilic group-modified graphene is 12-40%. USE - The adhesive mortar is useful in building materials and external wall insulation material (claimed). ADVANTAGE - The adhesive mortar has excellent frost resistance, low temperature film-forming property, high bonding strength at low temperature and normal temperature, excellent crack resistance and flexibility; meets the evaluation standard of the green product and can satisfy safety requirements of the external wall insulation system. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing bonding mortar.
