Energy-saving thermal-insulation material

Abstract

The energy-saving thermal insulation material comprises the following raw materials by weight: 60-80 parts of expanded perlite, 10-15 parts of sepiolite, 5-10 parts of activated carbon, 50-70 parts of polystyrene, 14-30 parts of latex powder, 3-5 parts of hydroxypropyl methylcellulose, 2-4 parts of wood fiber and 1-3 parts of polypropylene fiber. Beneficial effects of the present invention: raw materials are industrial waste at all levels, easy to make, both energy-efficient, and have good sound-absorbing, sound-insulating, heat-preserving, and heat-insulating functions, and heat-insulating powder is prepared with cement, and the heat-insulating material can be increased after being mixed with cement. strength and cohesion.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials for building walls, and relates to an energy-saving composite thermal insulation mortar for walls. Background technique [0002] Now people build a lot of buildings, but these buildings need to use a lot of building materials, consume a lot of non-renewable resources and energy, especially some buildings with poor thermal insulation, so that the heating in winter causes environmental pollution, and the cooling in summer Cause power supply shortage, also cause the massive consumption of energy simultaneously. Therefore, wall insulation is particularly important in building energy saving, and it is also an important link in building energy saving. The traditional way of thermal insulation of building walls in our country is to thicken the thickness of the wall to achieve the purpose of thermal insulation. Not only the project cost is high, but also the land resources are seriou...

Problems solved by technology

At present, there are many wall insulation materials in the construction market, such as: one is the wall insulation board of the plate type, the existing problems are: the production process is complicated, it takes up a lot of space, and the wall insulation layer made of it has poor compression resistance , prone to cracks; the other is closed-cell vitrified microbead insulation material. After the material expands, the surface is uranized for waterproofing, but the cohesion of the uranized material is poor, and it is prone to hollowing, hollowing, and The phenomenon of cracking, for this reason, special adhesives and anti-cracking agents must be used in use, so the production cost is high

Another kind is to use asbestos, perlite, reinforcing agent, binder and water as raw materials to make the wall insulation slurry material. Although it can achieve a certain insulation effect, the quality is not stable during use, and the transportation is also very difficult. It is convenient, and the asbestos in the material contains carcinogens that are harmful to human health. It is a restricted and banned material in the country, so it is inconvenient to promote and apply
