Western developed countries are leading the way in developing prefabricated buildings. Nowadays, prefabricated housing in Western developed countries has developed to a relatively mature and complete stage. The penetration rate of prefabricated buildings in many Western developed countries has reached 70%, especially in France, where the penetration rate of prefabricated buildings has reached 80%. Compared with foreign countries, the rise of prefabricated buildings in my country is relatively late. However, since 2015, my country's prefabricated buildings have developed rapidly, and the country's prefabricated penetration rate has increased from 0% to 38.5%, demonstrating huge construction capabilities. Of course, compared with foreign countries, our country still has relatively large room for development.
Construction sealant is used in every process and every material in the construction industry and is an essential material in construction projects. Building sealants are mainly used to seal various joints or holes in buildings to prevent gases, liquids, and solids from penetrating, and to prevent structural materials from being damaged when the structure is displaced, thereby achieving thermal insulation, sound insulation, waterproofing, dustproofing, It has the functions of gas-proof, fire-proof, corrosion-proof, shock-absorbing and preventing the accumulation of foreign matter in the joints. According to data from the China Adhesive and Adhesive Tape Industry Association, prefabricated buildings will become the dominant form of construction in the future. Therefore, in the future, building sealants should follow the footsteps of prefabricated buildings and develop sealants suitable for the field of prefabricated buildings. .
What should we pay attention to when it comes to prefabricated construction adhesives?
●Sealing performance
Water tightness and air tightness are the basic properties that prefabricated building adhesives should have. If the sealing performance of the adhesive is not good, leakage will occur and it will be easily affected by water or air, shortening the service life of the building. Therefore, prefabricated building adhesives Construction adhesives require a good seal.
●Green and environmental protection
Prefabricated buildings have the advantages of speed, efficiency, energy saving, and environmental protection. In order to adapt to the development of prefabricated buildings, pollution-free and environmentally friendly adhesives are imperative. They must meet the three major requirements of "environmental protection, health, and safety."
●Temperature resistance
Temperature resistance refers to the changes in the performance of an adhesive within a specified temperature range, including heat resistance, cold resistance and high and low temperature resistance. These temperature changes will also change the composition of the adhesive, thereby reducing the bonding strength. Therefore, construction adhesives must have excellent temperature resistance.
●Chemical resistance
Most synthetic resin adhesives and some natural resin adhesives will undergo different changes such as dissolution, expansion, aging or corrosion under the action of chemical media, resulting in a decrease in bonding strength. Therefore, prefabricated construction adhesives must be chemically resistant.
●Weather resistance
In view of the necessity for prefabricated buildings to be exposed to the outdoors, the adhesive must be able to withstand weather conditions such as rain, sunlight, wind, snow and moisture. Weather resistance also reflects the aging resistance of the adhesive layer under the long-term effects of natural conditions.
