Problems solved by technology

[0002] Water pipes are commonly used in people's lives and in industrial production processes, and their fire safety is very important. In addition to fire safety, the existing water pipes also need to have environmental protection requirements. However, the existing water pipes The pipe material is not environmentally friendly and has a great impact on the environment and human health
For this reason, people try various materials as water pipe materials to meet the above two requirements at the same time, but while pursuing environmental protection, the safety is also reduced, and it is often easy to cause fires when encountering failures or accidents. Therefore, how to It is a difficult technical problem to meet the needs of environmental protection and have flame retardant properties to ensure safety.

Abstract

The invention discloses an environment-friendly high-flame-retardant foaming material for a tap water pipe and a preparation method of the environment-friendly high-flame-retardant foaming material. The environment-friendly high-flame-retardant foaming material is prepared from isocyanate and a combination material according to the mass ratio of 1:1.6, wherein the combined material is specifically prepared from, by mass, 30-35 parts of polyether 3028, 10-18 parts of polyether 330, 10-15 parts of polyether 3360, 10-15 parts of reinforced glass fibers, 2.6-2.9 parts of silicone oil 8803, 1.2-2 parts of a catalyst DY828, 1.2-1.8 parts of a catalyst A33, 3.5-3.8 parts of water and 35-38 parts of a flame retardant DMMP. By adopting the materials and the method, the prepared foaming material is high in flame-retardant property, not prone to burn when the foaming material encounters with fire, and therefore fireproof security and personal security are guaranteed; in addition, due to the fact that various environment-friendly raw materials are matched, substances which are toxic and harmful to a human body cannot be released, and the environmental protection requirements are met.
