Description
Technical field
The present invention relates to a kind of polyurethane foam stabilizer and preparation method thereof, more specifically to a kind of polyurethane foam stabilizer that possesses good nucleation performance and preparation method thereof, this stablizer can be used for the hard polyurethane foams foam process.
Background technology
Urethane foam is a kind of important synthetic materials, has characteristics such as porousness, specific density are little, specific tenacity height, can be made into common soft bubble, high rebound foam and hard bubbles etc. according to the variation of raw materials used difference and prescription.Urethane foam is (like isocyanic ester by plurality of raw materials; Polyvalent alcohol; Water or whipping agent) (generally be no more than 1 minute) in the short period of time and carry out chemical reaction at the utmost point, and become colloid by liquid and become superpolymer again, experiencing complex processes such as foaming, gel therebetween.Therefore, must rely on suds-stabilizing agent to play regulating effect, just can make uniform in foaming, foam stabilization, make the uniform foams of abscess.Its role mainly contains: each component during 1. nucleation and emulsification are filled a prescription.The intermiscibility of each component in the foam formulation is relatively poor, needs the tensio-active agent of strong emulsifying capacity that it is mixed, thereby foamable reaction and crosslinking reaction are carried out smoothly.2. stable foam.Owing to add stablizer, the surface tension of material is reduced, make the air of sneaking into form nuclei of bubbles during stirring easily, these nuclei of bubbles play the effect of similar " nucleus ", the CO that produces during reaction
2Get into and promptly to generate bubble, and abscess is constantly grown up, uniform distribution and do not cause foam aperture and macropore to merge and make that foam seethes with excitement, the hole of collapsing.The number of bubble no longer increases in entire reaction course, and because the existence of suds-stabilizing agent makes the bubble size consistent.3. make foam perforate and " punching ".Bubble in the soft bubble must be that open cell type just can make the soft springiness of goods.Because the effect of suds-stabilizing agent, when system is in LV during the stage, cell wall is stable, and when air bubble growth when being suitable for the thickness of perforate, then can break is " perforate ", and " punching " or " venting " phenomenon when foam is raised to maximum height, is then arranged.
The silicon foams stablizer can significantly reduce the surface tension of foaming system as a kind of tensio-active agent, is widely used.In the foam forming process, the extraneous stirring to system acting W
Outward, maximum system energy increases thereupon, and energy difference is Δ E, W so before and after foam produces
OutwardR is low more for=Δ E=rA surface tension, and it is just big more then to apply the same bubble area A that merit produced, and explains that the bubble that produces is just many more, and then the abscess quantity of unit volume is just big more, and foam aperture is just more little, and foam is just fine and closely woven more.And surface tension is lower can to make foam more stable, plays better steady bubble effect.The Plateau border of bubble intersection and Laplace formula are Δ P=2r/R, and foam external and internal pressure as shown in Figure 1 is poor, and the A point is a concave meniscus, and Δ P is less than zero; The B place is close to the plane, and Δ P is zero, and liquid can flow to A from B, thereby causes lather collapse, and when surface tension is more little, pressure difference is also more little, and foam is just stable more.
Therefore use the organic silicon surfactant with special performance develop be used for polyurethane foamed material stablizer because its effect is remarkable, the innovation that has brought the polyurethane foamed material moulding process makes polyurethane industrial obtain tremendous development.In recent years, all kinds of polyether-modified ZGK 5 can obtain to further develop with its excellent foam stability, have progressively replaced traditional polyurethane foam stabilizer.Siloxane main chain in the polyether-modified ZGK 5 is as hydrophobic group, give the performance such as anti-stable, anti-aging, electrical isolation, softness of product fine, and hydrophilic polyether segment makes product have good surfactivity.Through change introducing kind, quantity and the position of polyethers, can regulate amphipathic property effectively, thereby obtaining different performances such as steady bubble, froth breaking, lubricated, emulsification.Like the patent No. is that the USP of US5844010 discloses the macromolecular compound of a kind of organic silicon block copolymer as stablizer; The patent No. is that the US5985948 USP then discloses a kind of organic silicon polyether copolymer foam stablizer that is used for high rebound foam; The patent No. is that the ZL200710025597.5 Chinese patent then discloses a kind of preparation method who is used for the low density and low heat conduction coefficient polyurethane foam stabilizer of pentamethylene foaming system.Prior art generally all is to be grafted on the containing hydrogen silicone oil with allyl polyether, makes the polyether type organic silicone tensio-active agent, and its foam stabilization performance is still waiting further raising.
