Abstract
The invention belongs to the technical field of polyurethane and particularly relates to a spraying polyurethane material of an environment-friendly foaming agent and a preparation method thereof. The spraying polyurethane material has the characteristics that CFA-8125 is used as a foaming agent, the foaming agent is an environment-friendly foaming agent with ODP (Ozone Depletion potential) value of 0 and GWP (Global Warming Potential) value of 1, can not destroy the ozone layer, also can not cause serious greenhouse effect, conforms to the requirements of future development of products, and is an ideal substitute of HCFC-141b; and the foaming agent has no flashing points, and when the foaming agent participates in production of component A, the equipment does not need to be transformed. The spraying polyurethane material and the preparation method have the beneficial effects that flame-retardant elements and flame-retardant structures are introduced into molecular chains to form structural flame retardance, reach corresponding flame-retardance level and maintain persistence of flame retardance. Simultaneously, by induction of a catalyst, excessive isocyanate generates a PIR (Polyisocyanurate) structure, and the PIR structure and high-functionality polyether generate high cross-linking degree, so that good size stability at high and low temperature is realized.
Description
technical field [0001] The invention belongs to the technical field of polyurethane, and in particular relates to an environmentally friendly foaming agent sprayed polyurethane material and a preparation method thereof. Background technique [0002] With the rapid development of China's economy and the enhancement of people's awareness of environmental protection, HCFC-141b has a certain destructive effect on the ozone layer. According to the resolution of the "Montreal Protocol", HCFC-141b has been discontinued in developed countries such as Europe and the United States. The regulated countries have entered the phase-out phase, and China, as the largest consumer of HCFC-141b, needs to make greater efforts to complete the phase-out task. [0003] Judging from the eliminated technologies of developed countries in the world, most enterprises now choose the third-generation foaming agent HFCs as the foaming agent in the spraying industry. Although the ODP value of HFCs foaming ...
