Abstract

The invention provides a lightweight thermal mortar. The lightweight thermal mortar is prepared from the following raw materials in parts by weight: 150-160 parts of shale pottery, 130-140 parts of pearlite, 30-40 parts of coal ash, 30-40 parts of expanded vermiculite, 15-20 parts of light calcium carbonate, 8-13 parts of kaoline, 10-15 parts of gingko dust saw, 10-15 parts of oak dust saw, 0.3-0.5 part of sodium dodecylbenzene sulfonate, 15-20 parts of latex powder, 140-160 parts of cement, 5-8 parts of polystyrene microspheres, an appropriate amount of water, 20-25 parts of auxiliaries and 7-9 parts of diatomite; the mortar is light in weight, good in thermal insulation property, high in bonding strength, non-toxic, tasteless, non-radioactive, harmful to a human body and free from pollution on the environment, and has the advantages of energy conservation and environmental protection; besides, the mortar is low in production cost; due to the auxiliaries, the compressive strength and flexural strength of the mortar are enhanced, and such properties as peaceability, anti-sagging property, thixotropy and anti-settling property of the mortar are improved.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a lightweight thermal insulation mortar and a preparation method thereof. Background technique [0002] Mortar is a common material for construction and is an essential material in construction. According to performance, mortar can be divided into many types, such as combined mortar, caulking mortar, thermal insulation mortar, etc.; [0003] At present, the performance and quality of mortar are different, which affects the use. Specifically, the factors that affect the performance of mortar include the workability, fluidity, water retention of freshly mixed mortar, and the strength of hardened mortar. New mortars need to be researched to have excellent construction and processability, sag resistance, thixotropy, anti-settling properties, storage stability, improved pumpability and shear thinning, and new materials need to be found , in order to improve its perform...
