What materials does the new insulation board have? Characteristics of new insulation board

In recent years, with the continuous acceleration of industrialization, thermal insulation materials have also developed rapidly. Using good thermal insulation technology and materials in industry and buildings can get twice the result with half the effort, so many buildings now use thermal insulation materials. There are more and more products of new thermal insulation materials in China. As an important material in architecture, we should know more about it. Next, let Bian Xiao take you to know.

1. What new insulation materials are there?

1. Phenolic foam

Phenolic foam material is formed by foaming thermosetting phenolic resin, which has the characteristics of light weight, smokeless, fireproof and non-toxic, and can be used in a wide temperature range without brittleness at low temperature. It is the most ideal new thermal insulation material for HVAC and refrigeration engineering. Phenolic foam is a good thermal insulation and energy-saving material because of its high closed cell rate and low thermal conductivity, and good thermal insulation, water resistance and moisture permeability. Other emitted materials are non-toxic and tasteless, and have no harm to human body and environment, which meets the national environmental protection requirements, so phenolic foam material is the most ideal new thermal insulation material.

2. Expanded vitrified microsphere material

Expanded vitrified microsphere material is a new type of thermal insulation material, which is used to paint the internal and external walls of buildings. Lightweight aggregate is an inorganic lightweight thermal insulation particle. 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 its price is very low, which has a wide market demand.

3. Rubber powder polystyrene particle material

Rubber powder polystyrene particle material is made of premixed dry-mixed mortar as the main cementing material, with proper admixture and anti-crack fiber, and polystyrene as lightweight aggregate, which is prepared in proportion and stirred evenly on site. Rubber powder polystyrene particle material has low thermal conductivity, good thermal insulation performance, high compressive strength, strong adhesion and simple construction technology, and is a new type of thermal insulation material with high utilization rate.

Second, the characteristics of new insulation board materials

1. A major feature of aluminum silicate insulation material is health! Aluminum silicate thermal insulation material is a newly developed green inorganic material, which overcomes the shortcomings of traditional thermal insulation materials, such as serious pollution and many volatile hazards. Aluminum silicate thermal insulation materials are all packaged in a group, which is green and environmentally friendly, non-toxic and harmless. Of course, thermal insulation materials require good thermal insulation effect.

2. The aluminum silicate thermal insulation material has achieved good results, and it has a great effect in thermal insulation. Aluminum silicate composite material has excellent sound absorption, heat absorption, high temperature resistance and frost resistance because of its material. In extreme weather, similar hot and cold will not have much impact.

3. The so-called A-class refers to incombustible materials, but at present, the popular building external insulation materials in China are mainly organic materials, and even if flame retardant is added, the height can only reach B 1 class. If the strictest fire protection order in history is strictly enforced, it means that China's thermal insulation material industry will face reshuffle or even elimination.

4. Therefore, thermal insulation materials, especially exterior wall thermal insulation materials, have considerable market capacity, which can bring greater business opportunities to manufacturers engaged in exterior wall thermal insulation materials.

5. In the renovation of new buildings and the renovation of old buildings, overcome the defects such as cracks, condensation, mildew and peeling on the wall; But also the integral bonding with the substrate is safe and reliable, has good randomness, has no cavity, and will not tear off under negative wind pressure. Effectively overcome the problems of rib falling and deformed brick angle outward after splicing.

I believe that every reader has a general understanding after reading the above contents, and I hope to have a reference when encountering the same problem in the future. Bian Xiao thanks every reader who reads. Your reading has brought us motivation.
