Inorganic composite waterproof, fireproof and heat preservation material for buildings

Abstract

An inorganic composite waterproof, fireproof and heat preservation material for buildings contains basic components of water, waterproof agents, perlite, porous ceramsites and cement, wherein the waterproof agents are colored waterproof agents with inorganic characteristics, the perlite is waterproof carbonized blind hole expanded perlite, the grain size of the perlite is 0.5-1mm, the volume weight of the perlite is 80-220 kg / m<3>, and the expansion times of the perlite is 8-15. Coal ash serves as the main raw material of the porous ceramsites, and the grain size of the porous ceramsites is 10-12mm. The cement is aluminium silicate cement added with modifying agents. According to material proportion, relative mass contents the of the perlite, the ceramsites, the cement and the waterproof agents meet requirements that the perlite occupies 59-61 parts, the ceramsites occupy 55-58 parts, the cement occupies 32-38 parts and the waterproof agents occupy 23-27 parts. The inorganic composite waterproof, fireproof and heat preservation material for buildings has the excellent performances in aspects of fire prevention and heat preservation, is high in indexes such as the heat conductivity coefficient, the dry appearance density, the material bonding strength and compression strength, and is low in cost.

Description

technical field [0001] The invention relates to the technical field of waterproof, fireproof and heat-retaining building materials, and in particular provides an inorganic composite waterproof, fireproof and heat-retaining building material. Background technique [0002] In the prior art, there are various kinds of waterproof and fireproof insulation materials for buildings, but their protective effect is generally low and the cost is high. [0003] As a common basic raw material for building waterproof and fireproof materials, expanded perlite is a white porous granular material formed by instantaneous expansion of volcanic vitreous lava after high-temperature roasting. It has excellent thermal insulation, filtration and adsorption properties, and Non-toxic, odorless, non-corrosion, acid-resistant, alkali-resistant, light bulk density, heat insulation, sound-absorbing; expanded perlite is rich in raw materials, low in price, safe in use, convenient in construction, and is w...

Problems solved by technology

However, because excavation of clay, shale, loess, sludge, etc. will cause soil erosion, environmental pollution, and damage to ecological balance, it is not suitable for popularization and application.

[0006] At present, the waterproof materials for construction used at home and abroad are usually organic waterproof materials. Most of these waterproof materials have a short service life, and most of the materials are in powder form, which will bring many difficulties to the construction.

Some use asphalt oil as waterproof material, which can only be used on the roof, and will emit an unpleasant smell under the sunlight, causing serious pollution to the surrounding environment

Some use organic waterproof materials instead of asphalt as waterproof materials, but they are basically five-color pigments. During continuous construction, it is difficult to distinguish which parts have been applied and which parts have not been applied, which has caused a lot of inconvenience to the construction.
