Abstract
The invention discloses a polyurethane mixed foaming agent. The polyurethane mixed foaming agent is characterized by comprising hexafluoro-2-butene and at least one of pentane, 245fa and 65mfc; excellent characteristics of hexafluoro-2-butene that ODP (ozone depleting potential) is 0 and GWP (greenhouse-warming potential) is 2 are fully utilized; and pentane, 245fa and 65mfc are mixed with hexafluoro-2-butene to obtain the mixed foaming agent which has a low GWP value and low combustibility and explosibility, thus meeting the global requirement for environment protection and safe production.
Description
Technical field
The present invention relates to whipping agent.
Background technology
The whipping agent of current employing comprises 141b, pentane, 245fa, 365mfc etc., but above-mentioned whipping agent is progressively eliminated due to the OPD of 141b, reason that GWP value is high, 245fa, 365mfc due to GWP value height Countries started reduce use, and pentane due to its inflammable and explosive property to factory safety require very high.
Summary of the invention
The object of the invention is: provide a kind of urethane mixed foaming agent, it has OPD, GWP value is low, nonflammable and explosive feature.
The present invention is achieved in that a kind of urethane mixed foaming agent, it is characterized in that: it is made up of at least one in hexafluoro-2-butylene and pentane, 245fa and 65mfc three;
(1) its weight part ratio is:
Or (two) its weight part ratio is:
Or (three) its weight part ratio is:
Hexafluoro-2-butylene 1 ~ 60 part, pentamethylene 0.5 ~ 20 part,
245fa 0.5 ~ 20 part, 365mfc 0.5 ~ 15 part.
A kind of urethane mixed foaming agent of the present invention, the ODP (ODP) making full use of hexafluoro-2-butylene is 0, GWP (greenhouse latent energy value) is the good characteristic of 2, be aided with pentane, 245fa, 65mfc mixture becomes mixed foaming agent to obtain low GWP value, low inflammable and explosive property, meets global Environmental Safety production requirement.
