Abstract
A thermal-insulation polyurethane plastics foaming agent is disclosed. The formula of the foaming agent contains, by weight, 1-20 parts of 1-chloro-3.3.3-trifluoropropene, 1-15 parts of 1.1.1.3-tetrafluoropropene and 1-20 parts of methyl formate. Gases which damage the ozone layer are not released during the using process of the foaming agent. GWP of the greenhouse effect is 0.
Description
Technical field
The present invention relates to especially a kind of whipping agent for polyurethane rigid foam plastic of a kind of heat-insulation foam material.
Background technology
The whipping agent of current most of foamed thermal insulating adopts this technology of 141b to belong to cambic substitute technology, and do not belong to the equivalent material of environmental protection, part uses the pentane-blown technology of environmental protection, but explosive inflammable.Chinese patent ZL200310112177.2, denomination of invention: a kind of polyurethane rigid foam plastic, adopt HFC-245fa as whipping agent, but need low temperature 5-10 DEG C of use, difficult operating procedure is complicated.
Summary of the invention
The object of the invention is: provide a kind of whipping agent of thermal-insulating polyurethane plastics it have that the easy to operate technique scope of application is wide and material thermal conductivity is low does not in use discharge the gas damaged the ozone layer, GWP is 0.
The present invention is achieved in that a kind of whipping agent of thermal-insulating polyurethane plastics, and the ratio of weight and number of its formula is:
1-chloro-3.3.3-trifluoro propene 1-20,1.1.1.3-tetrafluoeopropene 1-15,
Methyl-formiate 1-20.
The whipping agent of a kind of thermal-insulating polyurethane plastics of the present invention, does not in use discharge the gas damaged the ozone layer.Greenhouse effect GWP is 0.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
Embodiment 1
A whipping agent for thermal-insulating polyurethane plastics, the ratio of weight and number of its formula is:
1-chloro-3.3.3-trifluoro propene 1,1.1.1.3-tetrafluoeopropene 1,
Methyl-formiate 1.
Using method: at normal temperatures, adds 1 part of chloro-3.3.3-trifluoro propene of 1-, after mixing, then adds 1 part of methyl-formiate, then carry out physical mixed more than 1 hour, reach emulsifying effectiveness at normal temperatures in 1 part of 1.1.1.3-tetrafluoeopropene.
Be compared with the prior art: this system GWP is 0, it is blended lower thermal conductivity, simultaneously due to the change of boiling point, be applicable to normal-temperature operation, owing to reaching emulsifying effectiveness after co-blended, it has better mobility and intermiscibility, abscess is finer and closely woven, and foam epidermis is more added with compactness, improves thermal insulation effect, intensity is higher simultaneously, and shrinkability is better.
Embodiment 2
1-chloro-3.3.3-trifluoro propene 10,1.1.1.3-tetrafluoeopropene 8,
Methyl-formiate 10.
Embodiment 3
1-chloro-3.3.3-trifluoro propene 20,1.1.1.3-tetrafluoeopropene 15,
Methyl-formiate 20.
Above-described is only preferred embodiments of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the principles of the present invention, can also make some improvement and modification, this is also considered as protection scope of the present invention.
Claims (1)
1. a whipping agent for thermal-insulating polyurethane plastics, is characterized in that: the ratio of weight and number of its formula is:
