Problems solved by technology

[0003] In order to reduce the overall weight of the existing caravan, it will reduce its fire safety and stability. Since people spend almost half of the time in the caravan every day, the reduction of its fire safety increases the safety hazards of the caravan. Some RV interior sealing strips have poor environmental protection performance, and long-term use will cause great harm to the environment and the human body

Abstract

The invention discloses an environment-friendly flame-retardant polyurethane foam material for an interior trim sealing strip of a limo and a preparation method thereof. The foam material comprises isocyanate and a mixture, wherein the ratio of the isocyanate to the mixture in parts by mass is: isocyanate: mixture=1:1.5; the mixture comprises the following raw materials in parts by weight: 55 to 65 parts of JTM polyether 4110, 23 to 28 parts of polyether 4110, 2.5 to 2.8 parts of a stabilizer, 9 to 13 parts of diethanolamine, 3 to 4 parts of a catalyst APM9, 35 to 38 parts of a flame retardant and 3.5 to 3.8 parts of water. The foam material prepared from the raw materials which are reasonably proportioned has efficient flame retardancy, and is safe and environmentally friendly, the interior trim sealing strip of the limo prepared from the foam material is high in fire safety and stability, and hazards to the environment and human bodies are avoided.

Description

technical field [0001] The invention relates to a composite material and a preparation method thereof, in particular to a polyurethane environment-friendly flame-retardant foaming material for a car interior sealing strip and a preparation method thereof. Background technique [0002] With the development of the automobile industry, the caravan has gradually entered people's lives. The caravan is equivalent to a mobile home. The caravan can satisfy people's good travel life and alleviate the problem of lack of houses. Its internal configuration is complete, and the interior of the caravan needs to be sealed. The sealing strips are used to increase the sealing and heat preservation functions of the RV, and the fire safety of the sealing strips is extremely important. In addition to the fire safety, the sealing strips must ensure their stability and meet the requirements of lightweight. [0003] In order to reduce the overall weight of the existing caravan, it will reduce its ...
