Definitions
- the present invention falls within the field of compounds and compositions useful as binder building materials, and more specifically in the field of water-retaining additives for binder building materials such as special mortars and plasters.
- binder construction materials are increasingly being used to replace binder construction materials, as they have notable advantages both in terms of their conditions of work, such as manageability, grade of initial adhesion and water retention power during kneading, etc., as for its final properties, such as its adhesion, strength and finish qualities.
- additive compositions of binder construction materials incorporate additives, in addition to the components of traditional binder construction materials, which confer the aforementioned advantageous properties.
- H00A RECTIFIED (RULE 91) ISA / ES additives such as water retaining agents.
- a water-retaining agent is a product that due to its molecular structure and its surface properties binds to water through "weak bonds" and retains water in the matrix of the binders during the setting and hardening process. They also improve the rheology in the paste that forms.
- Water-retaining additives conventionally used for binder construction materials such as special mortars and plasters, are based on cellulosic derivatives, and no valid alternative to them is known to date of the present invention.
- EP-A-0773198 describes a thickener system containing at least one cellulosic ether, a starch ether, thickener components and a silicate of layers such as sepiolite, bentonite and other clays, corresponding to such additive of the market.
- cellulosic derivatives confer, based on their thickening effects, a greater consistency to the conglomerate building materials in addition to increasing their water retention and adhesion capacity.
- cellulosic derivatives have the disadvantage of being relatively expensive, therefore, conglomerating construction materials such as mortars and traditional plasters, lacking or with lower dosages than those derived from such derivatives, are still used, despite their inferior qualities. compared to additive compositions, for many applications where the use of a sufficiently additive binder composition would actually be more suitable.
- US-A-5637144 describes an asbestos replacement composition comprising water, retention agents and finely divided clays, especially bentonite, while US-A-4028127 describes a mixture of a plaster-based cement with the product resulting from reacting a hydroxyalkyl ether of guar with glyoxal which serves to
- the present invention also relates to additive compositions based on special plasters and mortars containing the additive as well as the use of the new additive in special plasters and mortars. DESCRIPTION OF THE INVENTION
- the objects defined above are achieved by means of a new additive for plasters and special mortars, free of cellulosic derivatives, whose additive comprises at least one solid mineral component selected from clays, and at least one modified natural rubber, in which the mineral component is a solid mineral component selected from rheological grade sepiolite, rheological grade attapulgite and mixtures thereof.
- the additive according to the invention comprises 20-75%, and more preferably 35-60%, of the solid mineral component; 25-80%, and more preferably 40-65%, of a modified natural rubber.
- the solid mineral component is at least one rheological grade clay selected from attapulgite, sepiolite and mixtures thereof.
- the solid mineral component is preferably rheological grade sepiolite as described for example in European patent applications EP-A-0454222 and
- EP-A-017029 the content of which is incorporated herein by reference.
- the rheological grade sepiolite marketed for example by TOLSA, S.A., Madrid, Spain under the brand
- PANGEL obtained from natural sepiolite by special micronization processes that substantially prevent the breakage of sepiolite fibers, easily disperses in water and other polar liquids and has an external surface with a high degree of irregularity, a high surface area specific, greater than 300 m2 / g, and a high density of active centers for adsorption, which give it a high water retention capacity by being able to form, with relative ease, hydrogen bridges with said active centers.
- the icrofibrous character of the rheological grade sepiolite particles makes it a material of high porosity and low bulk density. Due to the aforementioned properties, it is capable of forming high viscosity pastes with excellent thixotropic and pseudoplastic behavior.
- sepiolite has a very low cationic exchange capacity and electrolyte interaction is very weak, which in turn results in rheological grade sepiolite being practically unaffected by presence of salts in the medium in which it is found, and which remains stable in a wide pH range. This advantage is of the utmost importance since the media in which they work is high in salt.
- rheological grade sepiolite can also be attributed to rheological grade attapulgites with particle sizes smaller than 40 microns, such as for example the ATTAGEL product range (for example ATTAGEL 40 and ATTAGEL 50 ) manufactured and marketed by Engelhard Corporation, United States, and the MIN-U-GEL range of Floridin Company.
- ATTAGEL product range for example ATTAGEL 40 and ATTAGEL 50
- the modified natural gum can be selected from combinations of the glucose, mannose, galactose and / or glucuronic acid monosaccharides, modified by successive reactions of alkanilization and etherification with ethylene oxide and / or propylene oxide and / or butylene oxide.
- the modified natural gum is a galactomanne, that is, polysaccharides formed exclusively by galactose and mannose and modified by etherification with polypropylene oxide.
- the additive according to the present invention can be supplemented with other thickening agents such as modified starches or polyacrylamides.
- the additive according to the present invention can be prepared by mixing its components without any specific order of addition being necessary, for example for 5 minutes in a V-mixer until a homogeneous product is obtained.
- a binder construction material such as a special mortar or plaster
- the additive can be mixed together with the aggregate and cement fractions during manufacturing in the case of special mortars or, in the case of plasters, during the manufacture of plasters.
- the additive according to the present invention can also be added in situ during mixing with the kneading water.
- the additive according to the invention is incorporated into the cement fraction, a plaster fraction or the aggregate fraction in a proportion of 0.05-1.2% by weight, preferably 0.2-0.9% by weight.
- Example 1 A 50kg sample of the additive according to the invention was prepared by mixing in a V-mixer for 5 minutes, the following components:
- Example 2 Two samples of a glue mortar were prepared, one with a commercial cellulosic derivative (TYLOSE 10004 MH of HOECHST AG) as an additive, and the other with the additive according to the present invention prepared according to example 1. To do this, Portland cement, coarse aggregates with a particle size of less than lmm, fine aggregates with a particle size of less than 0.5mm, and respectively one of the aforementioned additives were mixed for 5 minutes, and each sample was mixed until Obtain glue mortars of the characteristics specified in the following table: Table 1:
- the cost of adding the additive for each ton of glue mortar was approximately 3,220, - ptas / t for sample I, that is to say for the conventional additive, and 2,250, - ptas / t for sample II, that is for the additive according to the present invention.
- the properties of the glue mortars according to samples I and II were evaluated in accordance with the European standards for adhesives for ceramic tiles. Water retention, consistency, vertical slippage, 28-day adherence and manageability after 20 minutes and 28 days of prepared glue mortars were testified. The results are reflected in the following table:
- Example 3 Two samples of a glue mortar were prepared, one with a commercial cellulosic derivative (METHOCEL HB of DOW CHEMICAL) as an additive, and the other with the additive according to
- H00A RECTIFIED (RULE 91) ISA / ES present invention prepared according to example 1.
- Portland cement, coarse aggregates with a particle size of less than lmm, fine aggregates with a particle size of less than 0.5mm, and respectively one of the two were mixed for 5 minutes.
- Additives mentioned above, and each sample was kneaded until glue mortars of the characteristics specified in the following table were obtained:
- the cost of adding the additive for each ton of glue mortar was approximately 2,875, - ptas / t for sample III, that is, for the conventional additive, and 2,200, - ptas / t for sample IV, that is for the additive according to the present invention.
