Abstract

The invention relates to the use of hydrocarbons or hydrocarbon mixtures as additives for reducing the dust caused by dry, especially powdery chemical products for construction, especially hydraulically binding or cement-based materials, such as tile adhesives, jointing mortar, filler, sealing materials and the like. Such dedusting additives based on hydrocarbons or hydrocarbon mixtures create a long-lasting dedusting effect on the chemical products treated therewith, an effect which is maintained both in closed storage and in open storage, especially under atmospheric oxygen, without affecting the treatment and application characteristics of the chemical products for construction treated in this way.

Description

Aliphatic hydrocarbon and the hydrocarbon mixture purposes in Powdered building chemical
Technical field
The present invention relates to the minimizing of the dust discharge that causes by exsiccant, especially pulverous building chemical or minimize, the described building chemical such as the hydraulicity or cement-based material are as having ceramic tile tackiness agent, jointing mortar, filler, sealing material etc. for example.
The invention particularly relates to the minimizing of the dust discharge that causes by exsiccant, especially pulverous building chemical (for example, plaster class or cement preparation) and/or minimize, especially when emptying the bag that contains this class system.
Therefore, the invention particularly relates to use hydrocarbon or hydrocarbon mixture as additive to reduce and/or to prevent the dust of exsiccant, especially pulverous building chemical, the for example hydraulicity or cement-based material (for example, ceramic tile tackiness agent, jointing mortar, filler, sealing material etc.).In addition, the present invention relates to be used to produce the dust with reduction form tendency, exsiccant, the method for especially pulverous building chemical and the product of producing by this method self.
In transportation and hybrid technique, exsiccant, especially pulverous building chemical such as the hydraulicity or cement-based material (for example, ceramic tile tackiness agent, jointing mortar, filler, sealing material etc.) produce a large amount of dust.Thereby, carried out a large amount of experiments for reducing or preventing from this product, to form dust.
For example, trial reduces for example dust formation of filler of hydraulic material by abrasive flour size or the particle composition of adjusting described powdery product, however feasible poor processability than coarse meal.
Another kind of known method is that for example water, aqueous solution or dispersion are assembled.Thereby from US-A-4780143 as can be known, form, before grinding cement, handle grog with resistance aqueous foam for reducing dust.Equally, proposed to be used for the plastisol additive of cement to reduce the dust formation of concrete (sprayed concrete) composition that can inject.If yet described product will grind subsequently or for example will or spray plaster as sprayed concrete, the temporal aggregate of hydraulic material is inessential.In the fine powder filler compound, when for example intention applied it to the floor and installs, then thicker aggregate was undesirable, because they become obvious on many slick flooring materials surface.
Similarly, be known as when spraying and reduce dust, in the mixing water of cement, add dust inhibitor.For this purpose, for example introduce as being used to reduce the dust tackiness agent of dust generation or the polyoxyethylene glycol or the oxyethane propylene oxide block copolymer of additive.Yet the additive of these types destroys processing characteristics usually, and particularly they can cause undesirable sclerosis delay of described chemical building products and deliquescence, and this is not wish with unaccommodated.On the other hand, refuse water additive to reduce dust formation if utilize, it also comprises a large amount of above-mentioned oxyethane propylene oxide block copolymers, then causes the wetting difficulty of described Powdered chemical building products.
In EP 0 403 874 B2, propose, the oxyethane propylene oxide block copolymer is generated effective additive of phenomenon as the dust that is used to reduce described exsiccant, hydraulic material, particularly cement filler mixture, by being joined, oxyethane obtains described oxyethane propylene oxide block copolymer in the polypropylene glycol especially, wherein based on the gross weight of described segmented copolymer, the content of oxyethane is 5～35wt%, and the weight average molecular weight range of described propylene glycol is 1500～3000.Yet the shortcoming of Cun Zaiing is that the described additive of discussing is relatively costly and often has to use to bring about tangible results in a large number here.
Similarly, proposed in the presence of, formed phenomenon (US-A-6 464 776) by adding the dust that polytetrafluoroethylene fiber reduces cement base composition based on defoamer alcohol and/or based on siloxanes.Yet, the optimum that the use of this fiber forms for described dust and to minimize reliably be not always enough.
Thereby, the present invention is based on following problem, promptly be provided for the effective system that reduces or prevent to form by the dust that exsiccant, especially pulverous building chemical cause, this at least greatly prevents or has reduced at least the outstanding problem of above-mentioned prior art.
Another object of the present invention has been to provide the reagent that is used to reduce dust, promptly be used to prevent or reduce the additive that exsiccant, especially pulverous building chemical dust or dust form, as the hydraulicity or cement-based material, as ceramic tile tackiness agent, jointing mortar, filler, sealing material etc. are arranged for example.Such additive makes the dust formation trend of this building chemical reduce on the one hand, however on the other hand should, at least not obvious processing characteristics or the application characteristic that destroys them.
The applicant unexpectedly finds, can minimize or reduce described exsiccant, especially pulverous building chemical effectively with hydrocarbon or hydrocarbon mixture, for example the dust of the hydraulicity or cement-based material (for example ceramic tile tackiness agent, jointing mortar, filler, sealing material etc.) forms phenomenon, and in fact to the processing characteristics of these products or application characteristic (as Hardenability, solidified nature, coating, consistence, viscosity etc.) does not have or obviously do not destroy.
Thereby according to the present invention first aspect, theme of the present invention is the mixture that utilizes hydrocarbon or hydrocarbon as being used to reduce the additive that exsiccant, especially pulverous building chemical play dirt, described chemical is the hydraulicity or cement-based material especially, as ceramic tile tackiness agent, jointing mortar, filler, sealing material etc.
