Description
Technical field
The invention provides a kind of preparation method of resistant to elevated temperatures porous plastics, particularly a kind of preparation method of resistant to elevated temperatures modified polyisocyanurate foamed plastics, belongs to technical field of polymer materials.
Background technology
The startup of current Market Situation, particularly environmental legislation, for example: require to use the whipping agent and the building industry that do not damage the ozone layer more and more higher, more and more stricter to the requirement of the flame retardant resistance of material of construction, the amount of being fuming, toxicity.Government limits production and the use of inflammable, high cigarette, high malicious building materials with legal provision, brought very large challenge to polyurethane products manufacturers.The lagging material that many common buildings, pipeline are used is now ordinary rigid urethane foam, this class material can withstand long term exposure the temperature of 100 ℃, but can not tolerate higher temperature, if this class A foam A is placed in the baking oven of 150 ℃ and toasts 96h, foam will seriously expand, be out of shape, and even has cracking to occur.And, ordinary rigid polyurethane foam meet fire safety rules aspect face huge challenge.If simple by adding a large amount of fire retardants to meet code requirement in formula system, can affect compressive strength and the dimensional stability of foam, and improve the cost of product.Therefore, hard polyurethane foams construction market wishes that its product can be constantly making moderate progress aspect thermal conduction and the key property such as fire-retardant, to extend volume growth.Because polyisocyanurate foamed plastics has higher dissipation of heat temperature, within the scope of approximately 480～550 ℃, than common rigid urethane foam, exceed a lot, its flame retardant properties, be fuming all excellent than common rigid urethane foam.But its goods are too crisp, and be difficult to processing.Therefore, need to carry out modification to it.
