Problems solved by technology

Although it solves the problem of flammability, toxicity and harm, it still has a density of 398kg / m3, which is relatively high; the thermal conductivity is 0.071W / m.K, and the thermal conductivity is poor; the rationality of the composition and ratio is flawed
There are problems with thermal insulation, sturdiness, poor weather resistance and short service life
As a result, the cost of maintenance and updating is high, which causes a great burden to the property owner (references, Chinese patent, application number: 201110250006.0, "Inorganic expanded fiber fireproof, waterproof and thermal insulation composite mud", inventors: Li Ronghua, Zhang Lin, Wang Zuoshu

Abstract

The invention provides inorganic waterproof heat insulation rock mud. The rock mud comprises Portland cement, bentonite, flocculent staple iron fibers, staple glass fibers, afrodite particles, oil shale particles and hydrophobic pearlite particles. The rock mud has the beneficial effects that the rock mud is scientific in formula, has excellent properties, is used after adding water and stirring the materials uniformly, and is simple in construction process; compared with the prior art, the rock mud has the advantages that the heat conductivity ratio of the rock mud is low by 29.6% and the heat conductivity is good; the bulk density is 39.7%, so that the weight load of a wall can be effectively reduced; by adopting the rock mud, buildings have stronger waterproofing, heat insulation and sound insulation functions; the rock mud is light, has high strength, is free from cracking, hollowing, falling, molecule fission and aging and has long service life as the wall; a fiber ball netty pulling and tying structure is formed after the rock mud is formed, so that the wall is free from moisture retention, moisture condensation and mildew and then the buildings are warm in winter and cool in summer; the rock mud has good intermiscibility, flame retardance and aging resistance, can be recycled, is low in comprehensive cost and is an energy-saving and environment-friendly building material.

Description

technical field [0001] The invention relates to an inorganic fire-proof and heat-preserving rock mud, in particular to a fire-proof, heat-preserving and sound-insulating material for building walls, building structures, roofs and floors. Background technique [0002] Building safety, fire prevention, energy saving, and environmental protection have become major strategic issues of the country. The external wall insulation system of the building adopts a composite system of organic materials, such as: polystyrene board, polyurethane, extruded board, phenolic board and insulation mortar. External insulation material. In the actual use process, there have been problems such as structural cracking, material shedding, flammability and harmful and toxic substances, and thermal insulation mortar materials are pulverized and out of sync with the life of the building structure. Some improved inorganic materials, such as inorganic expanded fiber fireproof, waterproof and thermal insu...
