Fire-resistant flame-retardant composite thermal insulation mortar and preparation method thereof

Abstract

The invention discloses fire-resistant flame-retardant composite thermal insulation mortar which is characterized by comprising the following raw materials in parts by weight: 300 to 350 parts of cement, 40 to 45 parts of clay powder, 23 to 26 parts of quartz powder, 12 to 15 parts of hydroxy propyl methyl cellulose ether, 40 to 45 parts of polypropylene short fiber, 30 to 35 parts of building crushed brick powder, 8 to 10 parts of antimony trioxide, 5 to 6 parts of sodium metasilicate, 4 to 5 parts of bentonite powder, 40 to 45 parts of oxidized starch, 24 to 28 parts of calcium propionate, 10 to 12 parts of borax, 30 to 35 parts of expanded pearlite powder, 5 to 10 parts of silica sol, 4 to 6 parts of modified nano-carbon powder, and 600 to 650 parts of water. The fire-resistant flame-retardant composite thermal insulation mortar mainly has the advantages that the workability, water-retaining property and heat insulating efficiency can be improved; common problems such as flaking, cracking and the like are solved; the anti-freezing, water-reducing, impermeable, durable, anti-crack, heat-insulating and heat-proof functions are realized after hardening.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a fire-proof and flame-retardant composite thermal insulation mortar and a preparation method thereof. Background technique [0002] my country's external wall insulation includes three categories: thermal insulation system, inorganic thermal insulation system and inorganic composite thermal insulation materials. Among them, it is mainly a kind of thermal insulation material. The production and construction technology is very mature, but it cannot be fireproof, pollutes the environment, and is 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 developme...

AI Technical Summary

Problems solved by technology

Among them, the main ones are insulation-like materials. The production and construction technologies are very mature, but they cannot be fire-proof, 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
