It destroys, it is very environmentally protective.
Specific embodiment
The present invention is described in further detail now.
Embodiment 1
The present embodiment 1 provides a kind of environmental type hard polyurethane foam combined polyether, comprising: polyether glycol composition, hair
Infusion and auxiliary agent；Wherein the foaming agent includes: methyl formate.
Specifically, the present embodiment uses methyl formate as foaming agent, compared with traditional HCFC-141B, reach same
Bubbling efficiency, the dosage of methyl formate is the one third of traditional HCFC-141B dosage, greatly reduces hard polyurethane foam
Cost of manufacture, and methyl formate ODP(ozone-depleting dive value) be zero, GWP(global warming potential) be zero, substantially reduce
The discharge of carbon dioxide, reduction damages atmospheric ozone layer, very environmentally protective.
The polyether glycol composition includes: sucrose polyols polyethers and sorbitol polyol polyethers.
Specifically, the sucrose polyols polyethers is to polymerize to obtain as initiator with propylene oxide using sucrose, hydroxyl value 430
~450mgKOH/g；The sorbitol polyol polyethers is to polymerize to obtain with propylene oxide using sorbierite as initiator, and hydroxyl value is
380~390mgKOH/g；It can be improved polyurethane foam by the Sucrose polyethers polyalcohol and sorbitol polyol polyethers
Intensity improves mobility, and can improve the shortcomings that methyl formate prepares polyurethane foam poor dimensional stability.
The foaming agent further include: water.
Specifically, will lead to when individually making foaming agent with methyl formate since methyl formate has certain solvent effect
Foam size bad stability, therefore in the present embodiment, the foaming agent further includes water, and the presence of water can make the urea in foam
Key increases, and then improves the dimensional stability of foam；In addition, the increase of urea bond can reduce increasing of the methyl formate to foam structure
Modeling effect, additionally it is possible to avoid influence caused by due to auxiliary agent is unstable.
The auxiliary agent includes: catalyst.
Specifically, the catalyst is such as, but not limited to using delay kicker or milky white type delayed catalyst；Prolong
The balance that slow kicker or milky white type delayed catalyst can make formation of foam react and cure, increases the milky white of foam
Time increases trickling property early period, and then optimizes the mobility of reaction mixture, while shortening demoulding time.
The auxiliary agent further include: fire retardant.
Specifically, since methyl formate belongs to flammable organic matter, because in order to improve the flame retardant property of manufactured foam,
The auxiliary agent further includes fire retardant, and the fire retardant such as, but not limited to uses TCPP (tricresyl phosphate (the chloro- 2- propyl of 1-) ester).
The auxiliary agent further include: stabilizer.
Specifically, the stabilizer such as, but not limited to uses silicone copolymers；The stabilizer can be in foaming process
In make foam stablize starting, so that foams is steadily risen the bubble that do not collapse in foam uphill process, and keep foam structure uniformly fine and closely woven,
Not brokenly bubble, and the stabilizer can also prevent foam contraction, rebound, use the present embodiment to combine so as to effectively improve
The dimensional stability of hard polyurethane foam made of polyethers.
