Siliceous heat-insulation composite material for wall

Abstract

The invention relates to a siliceous heat-insulation composite material for a wall, which comprises base materials and water. The base materials mainly comprise closed-cell expanded perlite, cement, building gypsum, inorganic mineral substance fibers, high-viscosity attapulgite clay, redispersible rubber powder, hydroxypropyl methyl cellulose auxiliaries and a water repellent, wherein the inorganic mineral substance fibers comprise alumina silicate fibers, brucite fibers, mineral cotton fibers and the like, and when the material is used, the weight ratio of the base materials to the water is 1:1.2-1.3. The material as an amorphous powdery heat-insulation material is excellent in energy conservation, heat insulation, sound absorption, flame retardance reaching level A1, fireproofing, seismic resistance, crack control, flexibility and weatherability, does not chemically react with the wall, is high in strength and ageing resistance, avoids deformation, crack, hollowing, shedding and is the same as the wall in service life in use. The material is green, environment-friendly and non-toxic, is applicable to heat insulation of an inner wall and an outer wall made of various wall base materials, a splitting wall and heat-insulation energy-saving projects such as roofs, basements, garages, stairs, corridors, fire-fighting accesses and the like.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a composite siliceous wall insulation material used for building walls, roofs, vegetable greenhouses and other walls. Background technique [0002] Existing insulation materials for various walls usually use benzene board, polystyrene particle heat insulation material, rock wool insulation board and phenolic insulation board. The above products and technologies have the following disadvantages: 1. Benzene board or extruded board insulation Although the thermal effect is relatively good, its biggest disadvantage is poor fire resistance. The wind pressure resistance of high-rise building insulation layers, especially low negative wind pressure resistance, is unsafe; Made of molecular materials, it will age and become brittle with the passage of time, the durability is short, and the service life is not the same as that of the wall; when the insulation layer is demolished...

AI Technical Summary

Problems solved by technology

[0002] Existing insulation materials for various walls usually use benzene board, polystyrene particle insulation material, rock wool insulation board and phenolic insulation board. The above products and The technology has the following disadvantages: 1. Although the thermal insulation effect of benzene board or extruded plastic board is relatively good, its biggest disadvantage is poor fire resistance, and the wind pressure resistance of high-rise building insulation layers, especially low negative wind pressure resistance, is not safe; The glue and fixing plastic expansion nails for the external benzene board are made of polymer materials, which will age and become brittle with the passage of time, and the durability is short, and the service performance is not the same as that of the wall; when the insulation layer with the building The demolition will cause great harm to the environmental safety of the city, increasing the pressure of the waste flow on the urban and rural environments; the externally bonded styrene board cannot meet the construction requirements for pasting glazed bricks on the exterior walls of buildings. If a fire or building More than 20 to 30 years, the adhesive and plastic expansion nails will become hard and brittle after the service life is reached, causing the glazed tiles attached to the outer layer to fall off and cause danger. exterior decoration is paint

Not only that, the construction quality control of this thermal insulation system is difficult, and the construction efficiency is low. When using panels, there are cold bridges and thermal bridges due to lax joints. The expansion nails used will cause cracks and water seepage in the walls, which will affect the quality of the building.

2. Using polyphenylene particles as insulation material is made by crushing benzene board into particles of about 20-30 meshes, and then adding cement and adhesive to mix. The insulation system of polystyrene particles as wall insulation generally consists of three layers: putty layer , primer layer and topcoat layer, which are mainly composed of organic materials, and its disadvantages are poor thermal insulation effect, poor aging performance, hydrophilicity, compressive and flexural strength, etc. Coating engineering and environmental protection and energy saving requirements

The production process of rock wool insulation board is complicated, which is extremely harmful to the human body. It has the same disadvantages as benzene board in many aspects such as strength, wind pressure resistance, and construction quality control difficulty, and the high cost is difficult for ordinary users to accept.
