Polystyrene thermal insulation mortar with high waterproofness and preparation method of polystyrene thermal insulation mortar

Abstract

Polystyrene thermal insulation mortar with high waterproofness is characterized by comprising the following raw materials in parts by weight: 300 to 340 parts of cement, 20 to 25 parts of building crushed brick powder, 10 to 12 parts of ceramsite, 10 to 12 parts of polystyrene granule, 5 to 7 parts of sodium carboxymethyl cellulose, 10 to 12 parts of polyvinyl alcohol, 40 to 45 parts of shrimp shell meal, 4 to 6 parts of Laiyang soil powder, 4 to 8 parts of melamine, 10 to 12 parts of light calcium carbonate powder, 4 to 6 parts of modified nano-carbon powder, and 600 to 650 parts of water. According to the invention, as cement is taken as a cementing material, meerschaum and shrimp shell meal are taken as main materials, a small quantity of polystyrene granules are taken as a size expanding agent, and polyvinyl alcohol is added for improving the workability, the polystyrene thermal insulation mortar has the advantages that the density and the heat conductivity are low; the compressive strength and the compression and shear bond strength are high; the heat-insulating and energy saving effects are obvious.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a polystyrene thermal insulation mortar with good water resistance and a preparation method thereof. Background technique [0002] my country's external wall insulation includes organic insulation systems, inorganic insulation systems, and organic and inorganic composite insulation materials. Among them, organic insulation materials are mainly used. The production and construction technology is very mature, but they cannot be fireproof, pollute the environment, and are easy to age. Inorganic thermal insulation mortar materials have attracted extensive attention due to their advantages such as low finished product, high strength, thermal insulation, fire prevention, and weather resistance. However, there are still disadvantages such as high cost and limited material sources, and there is still room for improvement. [0003] With the development of building green cons...

Problems solved by technology

Among them, organic insulation materials are mainly used. The production and construction technologies are very mature, but they cannot prevent fire, pollute the environment, and are easy to age.

Inorganic thermal insulation mortar materials have received extensive attention due to their advantages such as low finished product, high strength, thermal insulation, fire resistance, and weather resistance, but there are still disadvantages such as high cost and limited material sources, and there is still room for improvement.

[0003] With the development of building green construction, the use of abandoned concrete blocks, standard bricks and (hollow) aerated concrete blocks and other construction solid wastes has become a commonly used material for energy saving requirements, but due to its large size and relative strength Therefore, during the handling process, it is easy to cause damage to the edges and corners due to improper operation, and this part of the blocks will not be used for the main project
