Composite waterproof and thermal insulation material for building

Abstract

A composite waterproof heat preservation material for buildings contains basic components of water, waterproof agents, polyphenyl granules, porous ceramsites and cement. The waterproof agents are colored waterproof agents with inorganic characteristics. The polyphenyl granules are extruded polystyrene foam plastic granules, the polystyrene resin molecular weight is 190,000-600,000, and special fireproof coatings are coated on the surfaces of the polystyrene foam plastic granules. 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 all the components except water meet requirements that the polyphenyl granules occupy 6.5-8 parts, the ceramsites occupy 55-63 parts, the cement occupies 67-70 parts and waterproof agents occupy 18-21 parts. The composite waterproof heat preservation material for buildings has the excellent performances in aspects of water proofing, heat preservation, fire prevention and the like, 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 a composite waterproof and heat-retaining material for buildings. 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, polyphenylene particles have good thermal insulation performance, but their fireproof performance is low; [0004] As the most widely used and most used cementitious material in the field of building materials, the clinker of Portland cement is composed of four main minerals (C 3 S, C 2 S, C 3 A and C 4 AF), the calcination temperature is 1450°C. C 3 S and C 2 S is the main mineral in Portland cement clinker, and its hydration products are mainly calcium silica...

AI Technical Summary

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.
