Description
The present invention relates to the method for bonding object, described method is administered at least a bonded object (article) for the treatment of by the binder blend that will contain isocyanate groups and carries out from pressurizing vessel, described binder blend can obtain by following material is mixed: a) polymeric polyisocyanate and b) have a higher molecular weight compound of isocyanate-reactive group, c) whipping agent, d) foam is regulated additive, e) catalyzer and f) if suitable other additive, used polymeric polyisocyanate amount a) would be to make isocyanate groups that described mixture comprised more than isocyanate-reactive group; Wherein said foam is regulated additive (d) and is comprised silicone oil, and described binder blend is administered to adhesive face (bond area) immediately after step-down.
More embodiments of the present invention see among claim, specification sheets and the embodiment.Should be understood that the above-mentioned feature of theme of the present invention and treat that still the feature of elucidated hereinafter not only can be used for indicated concrete binding substances, and under the situation that does not depart from the scope of the invention, also can be used for other binding substancess.
From the one-component polyurethane foam of aerosol container (aerosol container) ejection is combination tool commonly used the building, is used to install building doors and windows, and as the through walls cavity that be used for pipe laying relevant with building or the packing material of opening.This aerosol container contains the end capped polyurethane prepolymer of NCO, and whipping agent and auxiliary agent.By discharging content by whipping agent, and the foaming by subsequently and the curing of air moisture, required foam formed.These foams are mainly as combination foam.A very big advantage of this combination foam is its ease for operation.
For example, a kind of such single component combination foam has been described among the WO2005/054324.---for example sash---assembly or be used for cavity foam-filled except being used for as combination foam, it also can be used as spray adhesive.In this case, for example, can be with insulcrete and roof cladding bonding mutually or be adhered to matrix (substrate).
Using known single component combination foam is that they have the trend that after takes place after using as a shortcoming of tackiness agent.In other words, constantly form bubble, cause and treat that the bonded object does not remain on their prepositions in adhint.Especially for the situation that insulcrete is attached to external surface of buildings, it is uneven that this mode may cause the surface of finishing to occur.
Therefore, an object of the present invention is to provide a kind of easy-operating binder blend, more especially be used for building, described binder blend can make treats that the adherent parts obtain best location.More specifically, the purpose of this invention is to provide a kind of method in conjunction with object, wherein after does not take place in binder blend.
Surprisingly, the present invention at the method for purpose by a kind of bonding object realize, described method is administered at least a bonded object for the treatment of by the binder blend that will contain isocyanate groups and carries out from pressurizing vessel, described binder blend can obtain by following material is mixed: a) polymeric polyisocyanate and b) have a higher molecular weight compound of isocyanate-reactive group, c) whipping agent, d) foam is regulated additive, e) catalyzer and f) if suitable other additive, used polymeric polyisocyanate amount a) would be to make isocyanate groups that described mixture comprised more than isocyanate-reactive group; Wherein said foam is regulated additive (d) and is contained silicone oil, and described binder blend is administered to adhesive face immediately after step-down.
Binder blend of the present invention is administered to from pressurizing vessel treats the bonded object.This binder blend can only be administered to by the ubiquitous internal pressure of institute in the aerosol container and treat the bonded object.This internal pressure is to produce by the evaporation of propellant gas mixture or step-down.Another kind may be by means of gas under pressure---for example pressurized air---discharges binder blend of the present invention from described aerosol container, and it is administered to the adhesive face for the treatment of in conjunction with object.In this case, to regulate that additive (d) contains silicone oil and use described binder blend immediately after step-down be necessary for the present invention for described foam.For example, using binder blend of the present invention by the metering rifle from pressurizing vessel is exactly this situation.For this metering rifle, the content in whole rifle all be in pressurizing vessel in the identical pressure of ubiquitous pressure.When the content that will discharge in the pressurizing vessel,, drop at this valve place pressure and to reach external pressure substantially the valve open in rifle exit.If described binder blend at first by for example gauge line, then can not reach effect of the present invention after pressure descends generation.

Method of the present invention is fit to bonding object highlightedly, especially at building field, more especially for mineral substrate.The feature of binder blend of the present invention on this effectiveness is that the bonding coat after does not take place.This makes method of the present invention more be particularly suitable for the bonding of surface portion, to be used for for example insulcrete or surface elements being applied to mineral substrate---for example other parts of plaster, stone or building---.The bonded object can remain on selected position by this way, thereby make---for example surface elements---, and best orientation becomes possibility.
The present invention will be described below by embodiment.
The preparation of polyol component
Polyol component by following material by being mixed with: 330g is the Aethoxy Sklerol of 1000g/mol by the initial preparation of glycerine based on propylene oxide and oxyethane and number-average molecular weight, 147g is the Aethoxy Sklerol of 4000g/mol by the initial preparation of glycerine based on propylene oxide and oxyethane and number-average molecular weight, the 40g number-average molecular weight is the polyoxyethylene glycol of 600g/mol, the 60g bromine content be about 31 weight % originate from Solvay, trade mark Ixol by name
The bromination polyether-tribasic alcohol of B 251,25g (originates from Goldschmidt, trade mark Tegostab by name as the polysiloxane-polyxyalkyl-blockpolymer of suds-stabilizing agent
B 2219), 0.3g originates from Bayer, trade name Baysilone
The polydimethylsiloxane of M100,60g Pyranton, 8g be as 2 of catalyzer, 2-dimorpholine base Anaesthetie Ether, and 330g trichloropropyl phosphate.
The preparation of binder blend in the aerosol container
With the described polyol component of 286g and 394g in the PMDI that 25 ℃ of following viscosity are approximately 200mPas packs the 1L aerosol container into.Described aerosol container is sealed with rifle valve (gun valve).Can in described aerosol container, be metered into the process gas mixture of 43g dme, 27g 30 weight % propane and 70 weight % butane subsequently by described valve, add 79g Tetrafluoroethane (R134a) at last.
By acutely shaking content homogenize with jar.Described prepolymer reaction causes aerosol container to heat up.
After storing 24 hours under the highest 50 ℃ heat condition, described prepolymerization reaction is stopped, so that described content can be used as tackiness agent.
Use as one-package adhesive
Described aerosol container is spun on the foam gun (foam gun), and by shaking the content homogenize with this jar.By driving this rifle, the foam mixture extruded is applied to the insulcrete surface with the form of the wide foam band of about 3cm.
The foam of (collapsing) will break---some air pocket---slightly, and shape is smooth sprawls with band, with can be fully bonding.The insulcrete that will have binder foam subsequently is fixed on the concrete walls.No after takes place, and described insulcrete remains on original position.
