The invention discloses thermal insulation bonding mortar prepared from foundry waste sand and a preparation process of the thermal insulation bonding mortar, and belongs to the technical field of thermal insulation bonding mortar, and the thermal insulation bonding mortar is prepared from the following components in percentage by mass: 10-30% of foundry waste sand of 50-300 meshes, 0-5% of foundry waste sand of less than 300 meshes, 0-3.6% of polyester fiber, 1-3% of phenolic resin, 5-10% of rubber powder, 30-35% of cement, 0-30% of filler and the balance of water. The foundry waste sand is used as a carrier of phenolic resin to form heat-preservation waste sand particles coated with a phenolic resin outer layer, and the heat-preservation waste sand particles can replace polyphenyl particles in original heat-preservation bonding mortar, so that the strength of the heat-preservation bonding mortar after solidification is improved, the utilization rate of the foundry waste sand is increased, and the crack resistance of the foundry waste sand is improved.
本发明公开了一种利用铸造废砂制作保温粘接砂浆及其制作工艺，属于保温粘接砂浆技术领域，包括由以下质量百分比组成的组分：50目～300目铸造废砂10～30％、300目以下铸造废砂0～5％、聚酯纤维0～3.6％、酚醛树脂1～3％、胶粉5～10％、水泥30～35％、填料0～30％、余量为水。利用铸造废砂作为酚醛树脂的载体，形成包覆有酚醛树脂外层的保温废砂颗粒，该保温废砂颗粒可取代原有保温粘接砂浆中的聚苯颗粒，不仅提高保温粘接砂浆凝固后的强度，还提高了铸造废砂的利用率以及其抗裂性能。
