The invention discloses a high-reflection thermal insulation mortar, which comprises a cementing group material, a thermal insulation aggregate and a reflective material, wherein the cementing group material comprises, in parts by weight, 30-50 parts of white cement, 10-30 parts of lime putty, 5-15 parts of clay, 15-45 parts of slag powder, 2-6 parts of dispersed latex powder, 0.5-1.5 parts of a water reducer, 5-15 parts of fly ash, and 2 parts of an agent masterbatch group material; the thermal insulation aggregate comprises 30-40 parts of fine sand, 30-50 parts of expanded perlite, 40-60 parts of glass beads, 5-15 parts of mineral wool, 1-3 parts of modified seaweed, 10-20 parts of silico-calcium, 5-15 parts of ground calcium carbonate and 0.5-1.5 parts of an additive; and the reflective material comprises the following components in parts by weight: 1-3 parts of titanium dioxide, 0.2-0.4 part of nickel titanium yellow powder and 0.1-0.3 part of cobalt aluminum blue powder. The reflective material is added into the mortar, white, yellow and blue cold color series pigments are adopted as the reflective material, transmission and absorption of infrared rays by a wall surface are reduced, the sunlight reflectivity and the near-infrared reflectivity of the surface of the mortar are greatly improved, on the one hand, the thermal insulation effect on the wall body is achieved, and on the other hand, wall cracking caused by large temperature difference between the inside and the outside of the wall is avoided.
本发明公开了一种高反射隔热砂浆，包括胶结组料、隔热骨料和反光料，按重量份计，胶结组料包括白水泥30‑50份、石灰膏10‑30份、黏土5‑15份、矿渣粉15‑45份、分散乳胶粉2‑6份、减水剂0.5‑1.5份、粉煤灰5‑15份和剂母组料2份；隔热骨料包括细沙30‑40份、膨胀珍珠岩30‑50份、玻化微珠40‑60份、矿棉5‑15份、改性海藻1‑3份、硅钙土10‑20份、重钙5‑15份、添加剂0.5‑1.5份；反光料包括钛白粉1‑3份、镍钛黄粉0.2‑0.4份、钴铝蓝粉0.1‑0.3份。本发明中通过向砂浆中添加反光料，作为反光料采用白色、黄色和蓝色的冷色系颜料，减少墙面对红外线的透过和吸收，使砂浆表面的太阳光反射比和近红外反射比大大提高，一方面起到了对墙体的隔温效果，另一方面避免了墙体内外温差较大造成墙体开裂的情况。
