Foam glue, the full name is single-component polyurethane foam caulking agent (OCF) is a polyurethane adhesive mainly used for caulking and sealing of building doors and windows. It can form foam in contact with moisture in the air. Good quality foam adhesive has high hardness, strong adhesion and foam density after curing. It is delicate and can effectively play the role of thermal insulation, sound insulation and waterproofing. It is a good and widely used building auxiliary material.
With the popularity of styrofoam in the market, people’s performance requirements for styrofoam are no longer just filling. More users are beginning to pay attention to the resistance of styrofoam. combustion performance. Today, the author will introduce to you the importance of flame retardant and fireproofing of styrofoam.
1, fire cases caused by improper use of foam rubber:
On April 22, 2000, a fire broke out in the chicken processing workshop of Fengxu Industrial Co., Ltd. in Qingzhou City, Shandong Province, killing 38 people. The public security fire department found out that the cause of the fire was caused by the overheating of the fluorescent lamp ballast, which ignited the polyurethane foam insulation material.
On November 15, 2010, a fire broke out in the teachers’ apartment on Jiaozhou Road, Shanghai. Many retired teachers lived in the apartment, and the entire building was destroyed. The fire surrounded the building and many residents in the building were unable to be rescued. The fire killed 58 people. The cause of the accident was due to the lack of a certificate WelderFour persons The criminal suspecthas been detained by the public security organs in accordance with the lawCriminal detention,A large amount of polyurethane was used illegally at the accident scenepolyurethane font>Foam glueand other flammable materials.
February 3, 2011, Dynasty Wanxin Building, Shenyang, Liaoning CityA fire suddenly broke out. The cause of the fire is suspected to be caused by accidentally setting off fireworks, which caused the exterior of the building to burn.The polyurethane foam of the building is a flammable material, which further contributed to the spread of the fire.
November 21, 2015, Henan ProvinceNo. 1, Zhongzhan District, Jiaozuo City A fire broke out in the cold storage factory. According to the workers, the fire occurred due to Gathering in cold storageEster foamgluecaused by the explosion. After the explosion, the iron barrel happened to fly into the temporary house opposite. The temporary house was set on fire.
2. The importance of flame retardant and fireproofing of styrofoam:
The above fire cases are all related to foaming The use of glue is related, so it can be seen that flame-retardant foam glue is very important and necessary to use in our daily lives, and it needs all of us to pay attention.
In order to conscientiously absorb Shanghai Jiaozhou Road Teachers Apartment<font face Lessons learned from the "11·15" and "2·3" fires in Shenyang Dynasty Wanxin Building. On March 14, 2011, the Ministry of Fire Protection Bureau issued the "About Further Clarifying the Fire Supervision and Management of External Insulation Materials for Civil Buildings" "Notice on Requirements" (public notice [2011] No. 65), which puts forward emergency requirements for the use and management of building exterior wall insulation materials. On December 30, 2011, the State Council issued the "Opinions of the State Council on Strengthening and Improving Fire Protection Work" (Guofa [2011] No. 46) and the newly promulgated "Regulations on Fire Protection Supervision and Management of Construction Projects" on July 17, 2012. Clear provisions are made on the fire protection performance and supervision and management of external insulation materials used in new construction, expansion and reconstruction construction projects. After research, the "Notice on Further Clarifying the Relevant Requirements for Fire Supervision and Management of Exterior Insulation Materials for Civil Buildings" will no longer be implemented.
The fire protection agencies of local public security organs must strictly implement the State Council Documents and regulations of the Ministry of Public Security. Municipalities, provincial capitals, sub-provincial cities and other large cities must formulate and implement more stringent fire safety standards for fire protection design of construction projects to ensure fire safety of construction projects.
It can be seen that the flame retardant and fireproof performance of polyurethane foam is very important. More and more projects Start using flame-retardant foam for construction. With the future market development and responseCivil buildings have increasingly higher fire protection requirements, and the market share of fire-resistant and flame-retardant foam will also increase.
