Abstract

The invention discloses exterior wall putty with capacity of energy saving and heat preservation. The exterior wall putty is prepared from main raw materials by weight as follows: 36-46 parts of talcum powder, 16-24 parts of silicon dioxide, 8-14 parts of hydroxypropyl methyl cellulose, 5-10 parts of plant ash, 4-6 parts of benzoic acid, 3-5 parts of citric acid, 3-5 parts of corn starch, 1-3 parts of saw dust, 3-6 parts of aluminum powder, 4-8 parts of methylcellulose, 4-6 parts of boric acid and 22-26 parts of water. The exterior wall putty can reflect most ultraviolet rays in sunlight, thereby reducing ultraviolet ray erosion of a heat insulation board and having the advantages of good heat insulation performance, high bonding strength, good anti-cracking performance and the like.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an exterior wall putty capable of energy saving and heat preservation and a preparation method thereof. Background technique [0002] Putty is a supporting product used for base treatment when building fillers are painted. The basic function of putty is to fill the defects of the base layer of the wall and level the base layer, thereby increasing the flatness of the base layer. The special functions of putty include crack resistance and various decorative shapes. Putty is generally composed of base material, filler, water and additives. The base material, also known as the binder, is the most important component of the putty, and it mainly plays various functions such as bonding. The filler mainly acts as a filling, and the commonly used ones are calcium carbonate, talcum powder and quartz sand. Additives include thickeners, water retaining agents, preservatives, e...
