Abstract

The invention discloses an environment-friendly polyurethane foaming material for a luggage case plate of a spacecraft and a preparation method of the environment-friendly polyurethane foaming material. The environment-friendly polyurethane foaming material for the luggage case plate of the spacecraft is prepared from the following components in parts by mass: isocyanate and a composite material at the ratio of 1 to 1.8, wherein the composite material is prepared from the following components in parts by mass: 35 to 45 parts of polyether 835, 20 to 25 parts of polyether 10200, 35 to 40 parts of polyether 10300, 35 to 40 parts of polyether 8310, 2.5 to 3.0 parts of silicone oil, 1.5 to 1.8 parts of a catalyst HP17, 1.5 to 1.8 parts of a catalyst HP50, 3.0 to 3.3 parts of water and 35 to 40 parts of a flame retardant TCPP (Testosterone Cyclopentylpropionate). By adopting the material and the method, disclosed by the invention, the prepared environment-friendly polyurethane foaming material has a high flame-retarding property and is not easily combusted at high temperature and when meeting fire; furthermore, a prepared luggage case of the spacecraft has very light weight and can be adaptive to weight requirements of the spacecraft; raw materials for preparing the foaming material are environment-friendly raw materials so that substances which are toxic and harmful to human bodies are not released.

Description

technical field [0001] The invention relates to an environment-friendly polyurethane foam material for a spacecraft trunk board and a preparation method thereof. Background technique [0002] At present, with the development of spacecraft, the suitcase is an important part of the spacecraft, especially the manned spacecraft, and its fire safety is very important. The capacity of the existing spacecraft suitcases is also expanding. In addition to fire safety, it also needs to have the characteristics of light weight, high strength, high density, and high environmental protection to meet the requirements of the overall weight of the spacecraft and storage luggage. In order to achieve this purpose, various materials have been tried as spacecraft The material of the trunk board. However, the pursuit of light weight also reduces safety. The spacecraft must not allow accidents and must meet high-quality requirements. Therefore, how to meet the requirements of lightweight and hav...
