Abstract

The invention relates to a polyisocyanurate material catalyzed by using an ionic liquid and a preparation method of the polyisocyanurate material. The polyisocyanurate material is composed of the following raw materials in parts by weight: 150-170 parts of polyisocyanate, 10-12 parts of a combined polyether, 10-14 parts of a flame retardant, 2-3 parts of a catalyst, 1-2 parts of a stabilizer, 20-30 parts of a foaming agent, and 0.5-1.0 part of water, wherein the flame retardant is a nanoparticle flame retardant, and the catalyst is an ionic liquid catalyst. The preparation method comprises thefollowing steps: firstly mixing the ionic liquid and the combined polyether, then pouring the mixed material and the remaining raw materials into a mold through a high-pressure foaming machine, performing a reaction, and performing demolding to obtain the polyisocyanurate material. The polyisocyanurate material provided by the invention has the advantages that a product has good low-temperature dimensional stability, the flame retardant and the foaming agent do not contain halogen atoms, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polyisocyanurate material catalyzed by an ionic liquid and a preparation method thereof. Background technique [0002] Polyurethane materials have been widely used in various industries such as automobiles, construction, home appliances, and energy. Among them, polyisocyanurate material (polyisocyanurate) is widely used in storage, transportation and construction of liquefied natural gas, liquefied ethylene and liquefied petroleum gas due to its good flame retardancy, low linear expansion coefficient and thermal conductivity. It is widely used in thermal insulation and other fields. However, due to the complex reaction process and slow curing process of polyisocyanurate materials, the requirements for processing technology are very strict. In addition, the traditional amine, tin and mercury catalysts also have certain pollution to the environment. [0003] Ionic li...
