When decorating a house, you need to pay attention to wall decoration. Walls can be divided into interior walls and exterior walls. Exterior walls need to pay more attention to insulation. Exterior wall insulation boards will be used. What are exterior wall insulation boards? What are the materials for exterior wall insulation boards? Today we will talk about the issue of exterior wall insulation panels.
1. What are exterior wall insulation panels?
Exterior wall insulation panels are also called horizon building exterior wall decorative integrated panels. It is composed of polymer mortar, fiberglass mesh, flame-retardant molded polystyrene foam board (EPS) or extruded polystyrene board (XPS) and other materials, and integrates functions such as exterior wall insulation board. Factory production and on-site bonding construction are the preferred materials to meet the current energy-saving needs of housing buildings, improve the insulation level of exterior walls of industrial and civil buildings, and are also the preferred materials for energy-saving renovation of existing buildings. It is used for high-rise exterior walls, indoor shopping malls, and industrial equipment. It has low cost, good corrosion resistance, and no pollution.
2. What are the materials of exterior wall insulation panels
1. Exterior wall insulation mesh
Exterior wall insulation mesh Exterior wall insulation mesh Cloth (glass fiber mesh cloth) is made of medium-alkali or alkali-free glass fiber mesh as raw material, woven into glass fiber mesh cloth as the base material, and then coated with acrylic acid polymer liquid and dried. A new type of alkali-resistant product. This product has the characteristics of stable structure, high strength, good alkali resistance, anti-corrosion, anti-cracking and other characteristics. It has the best reinforcement effect and is simple and easy to construct. It is mainly suitable for reinforcing the internal and external surfaces of cement, gypsum, walls, buildings and other structures and preventing cracks. It is a new building material for exterior wall insulation projects.
ZrO2-containing alkali-resistant coated glass fiber mesh cloth is based on ZrO2-containing glass fiber woven fabric, which is soaked and coated with polymer alkali-resistant emulsion. As a result, it has excellent alkali resistance, flexibility and longitudinal and latitudinal tensile strength reaching the JG158-2004 national standard, and can be widely used in building particle exterior wall insulation systems, waterproofing, anti-cracking, etc.
2. Phenolic resin foam material
Phenolic foam material is a polymer organic rigid aluminum foil foam product. It is foamed from thermosetting phenolic resin. It is lightweight and fireproof. , does not burn when exposed to open fire, smokeless, non-toxic, non-dripling, has a wide operating temperature range (-196 ~ 200℃), does not shrink or embrittle in low temperature environments, and is an ideal thermal insulation material for HVAC and refrigeration projects. Due to the phenolic foam High closed cell ratio means low thermal conductivity, good thermal insulation performance, water resistance and water vapor permeability, making it an ideal thermal insulation and energy-saving material. Since phenolic has a benzene ring structure, it is dimensionally stable and has a change rate of 1. It has stable chemical composition, anti-corrosion and anti-aging, and is especially resistant to corrosion by organic solutions, strong acids and weak alkali. Freon is not used as a foaming agent in the production process to comply with international environmental protection standards, and its molecular structure contains hydrogen, oxygen, and carbon elements. When decomposed at high temperature, the gas that escapes is non-toxic, odorless, and harmless to the human body and the environment. Comply with national green environmental protection requirements. Therefore, phenolic super composite board is the most ideal environmentally friendly green thermal insulation material with fire protection, heat insulation, energy saving and beauty.
Phenolic foam is known as the king of thermal insulation materials and is a new generation of thermal insulation, fireproof and sound insulation materials. In developed countries, phenolic foam materials have developed rapidly and have been widely used in construction, national defense, foreign trade, storage, energy and other fields. Phenolic materials account for 40% of the soundproofing and thermal insulation foam used in the US construction industry; Japan has also established a phenolic foam popularization association to promote this new material.
Phenolic foam is also internationally recognized as the most promising new insulation material in the construction industry. Because this new material is fundamentally different from the usual polymer resin materials obtained by adding flame retardants. It does not burn or melt in a fire, nor does it emit toxic smoke. It is also lightweight, non-toxic, and non-toxic. It has the advantages of corrosion, heat preservation, energy saving, sound insulation, low price, and does not require Freon foaming. It has no environmental pollution, good processability, and convenient construction. Its comprehensive performance is unmatched by various insulation materials.
It has undisputed comprehensive advantages in refrigeration and cold storage, as well as insulating industrial pipelines and equipment in the petrochemical industry, building partition walls, exterior wall composite panels, suspended ceilings, sound-absorbing panels, etc. It solves the problem of insufficient fire resistance of other organic materials. Ideal, while inorganic materials have problems such as high water absorption, easy condensation, and itchy skin during construction. They are the third-generation best insulation materials for air-conditioning systems and various electrical appliances.
In addition, due to its poor flame retardant performance and the emission of toxic gases, phenolic foam materials may replace it and become a very competitive new building material.
3. Foamed cement insulation material
Foamed cement was first used in Germany and was introduced to our country around 1980. The foaming agent is mechanically fully foamed through the foaming system of the foaming machine, and the foam and cement slurry are evenly mixed, and then the pumping system of the foaming machine is used for cast-in-place construction or mold forming. After natural curing, It is a new type of lightweight thermal insulation and fireproof material containing a large number of closed pores. It is a bubble-like thermal insulation material, and its outstanding feature is the formation of closed foam pores inside the concrete, making the concrete lightweight and thermally insulating.
It can be seen that the exterior wall insulation board is an integrated panel for the exterior wall decoration of Horizon Building. It mainly includes exterior wall insulation grid cloth, phenolic resin foam material, foam cement insulation material, etc., each with its own characteristics. People can choose and buy according to actual needs.
