1. What new thermal insulation building materials are there?
1, a new thermal insulation building material-aluminum silicate thermal insulation material, also known as aluminum silicate composite thermal insulation coating, is a new type of environmental protection wall thermal insulation material, which meets the national building standards and is an essential material for many real estate developers and engineering contractors. Aluminum silicate thermal insulation material takes natural fiber as the main raw material, and then adds a certain amount of inorganic auxiliary materials to make a new type of green inorganic one-component packaging dry powder thermal insulation coating. Before construction, we mixed aluminum silicate insulation material with water, scraped it on the surface of insulation wall, and dried it to form microporous wangzhuang insulation layer.
2. New thermal insulation building materials-phenolic foam phenolic foam is made of thermosetting phenolic resin, which has the characteristics of light weight, smoke-free, fire-proof and non-toxic, with a wide temperature range and will not be brittle at low temperature. It is an ideal new thermal insulation material for HVAC and refrigeration engineering. Because phenolic foam has the characteristics of closed cell and low thermal conductivity, it has good thermal insulation performance, water resistance and water vapor permeability, and is a good thermal insulation and energy-saving material. Other emitting materials are non-toxic and tasteless, and have no harm to human body and environment, which meets the requirements of national environmental protection and is an ideal new thermal insulation material.
3. A new type of thermal insulation building material-expanded vitrified microsphere material is a new type of thermal insulation material used to paint the internal and external walls of buildings. Lightweight aggregate is inorganic lightweight thermal insulation particles, and dry powder mortar composed of other fillers such as cementitious materials has excellent properties such as energy saving, waste utilization, fire prevention, freezing resistance, aging resistance, thermal insulation and so on, and the price is very low, so it has a wide market demand.
2. What are the new building materials for external wall insulation?
1, XPS extruded polystyrene foam board. Also known as polystyrene extruded board (XPS); It has a complete closed-cell honeycomb structure, and its density, water absorption, thermal conductivity and vapor permeation coefficient are lower than other types of plate-like thermal insulation materials, so it has the characteristics of good strength, light weight, good air tightness, corrosion resistance, aging resistance and low price, and is widely used in the fields of thermal insulation in construction industry, anti-freezing thermal insulation in highways, railways, airports and squares, and home decoration.
2. Thermal insulation mortar. Thermal insulation mortar is a kind of ready-mixed dry powder mortar with various lightweight materials as aggregate, cement as binder and some modified additives, which is mixed by production enterprises. Mainly used for building external wall insulation, with the advantages of convenient construction and good durability.
3. Phenolic foam. Phenolic foam is an internationally recognized new building insulation material, which has a bright future. Because this new material is essentially different from the material obtained by adding flame retardant to ordinary polymer resin, it will not burn, melt or emit toxic smoke in fire, and has the advantages of light weight, non-toxicity, non-corrosion, heat preservation, energy saving, sound insulation and low price.
What is the new thermal insulation building material? What are the new building materials for external wall insulation? The external wall must have good thermal insulation measures, and there are relatively many materials for thermal insulation of the external wall. Therefore, when people choose, they must first have a certain understanding of the materials and choose regular merchants to buy them.
