Abstract

The invention discloses novel efficient energy-saving type mortar, which is prepared from the following raw materials in parts by weight: 36 to 42 parts of cement, 28 to 32 parts of quartz sand, 18 to22 parts of modified methylcellulose, 16 to 20 parts of vinyl ester resin, 14 to 18 parts of cellulose diacetate, 12 to 14 parts of nano calcium carbonate, 6 to 10 parts of magnesium limestone, 4 to8 parts of melamine, 1 to 3 parts of water-retaining agents, 1 to 2 parts of thickening agents and 1 to 3 parts of water reducing agents. The invention aims at providing the novel efficient energy-saving type mortar; the mortar has high strength and excellent water penetration resistant capability; in addition, good heat preservation and heat insulation effects are achieved; compared with the prior art, the mortar has the advantages that the effect is obviously improved; the use values are higher; the application prospects are good.

Description

technical field [0001] The invention relates to the technical field of mortar, in particular to a novel high-efficiency and energy-saving mortar and a preparation method thereof. Background technique [0002] Mortar is a bonding substance used in building bricks. It is composed of a certain proportion of sand and cementing materials (cement, lime paste, clay, etc.) It is called cement lime mortar), lime mortar and clay mortar. According to the composition materials, ordinary mortar can also be divided into: lime mortar: it is made of lime paste, sand and water according to a certain ratio. It is generally used for low-strength requirements. Wet masonry and plastering layer; cement mortar: made of cement, sand and water according to a certain ratio, generally used for masonry, wall or ground in wet environment or water; mixed mortar: in cement or lime mortar It is made by adding appropriate admixtures such as fly ash and diatomaceous earth to save the amount of cement or lim...
