Definitions
- Building boards based on gypsum such as gypsum plasterboard and gypsum fibreboard, are used in drywall construction to produce floors, walls and ceilings.
- Typical gypsum-based building boards have a core made of set calcium sulfate dihydrate. These are covered with cardboard or fleece (glass fiber fleece). Typical strengths are 6; 9.5; 12.5; 15 and 20 mm.
- panels with increased moisture stability for example panels with increased moisture stability, panels with increased fire resistance or with reduced sound transmission behavior.
- Plaster is a covering of raw masonry or raw ceilings made of mortar. These are often used as a base for further decoration indoors, and as protection against the weather for external walls.
- the object of the present invention was to provide building materials with improved properties. Surprisingly, it was found that building materials based on gypsum, which contain 1 to 25% by weight of zeolites, can lead to a reduction in indoor air pollutants. Preferred zeolite contents are at least 5% by weight, more preferably at least 10% by weight, and the ranges 5 to 20% by weight or 10 to 15% by weight are particularly preferred.
- the contents relate to the proportion of zeolite in the dried gypsum-containing mass, without e.g. Carton or fiber content.
- zeolites which are not synthetically produced (for example by reacting substances containing SiO 2 and AI 2 O 3 with alkali metal hydroxides at temperatures).
- BESTATIGUNGSKOPIE ture greater than 50 ° C in the aqueous phase So naturally occurring zeolites are those that are mined from deposits.
- Particularly suitable zeolites are those with a mineral phase composition which is selected from the group consisting of clinoptilolite, heulandite, chabasite, phillipsite, morderite and mixtures thereof.
- the zeolites are not only thermally activated, i.e. thermally drained, but surprisingly also usable natively.
- the zeolites are used natively, i.e. without thermal activation or drainage.
- the drainage of zeolites can e.g. can be measured by thermogravimetric analysis (TGA).
- Fig. 1 shows a TGA diagram for a naturally occurring zeolite. When the temperature increases, water is released over a larger temperature range. The mass of the sample as a function of the temperature and the changes in mass are shown (corresponds to the 1st derivative).
- FIG. 2 shows a TGA diagram for a mixture of 90% by weight of stucco and 10% by weight of naturally occurring zeolite.
- the mixture is mixed with water and, after setting, predried at about 40 ° C.
- the amount of water released found in the TGA analysis corresponds to the amount of water in the gypsum; the water from the zeolite is no longer found.
- the mass of the sample as a function of the temperature and the changes in mass are shown (corresponds to the 1st derivative).
- such a zeolite shows the activity according to the invention for reducing air pollutants.
- the building materials preferably contain zeolites with a grain size ⁇ 200 ⁇ m, preferably less than 150 ⁇ m. The easiest way to do this is to finely grind it. Particularly suitable zeolites have d50 values between approximately 30 and approximately 90 ⁇ m, even more preferably between 40 and 70 ⁇ m.
- the zeolites preferably have an oil number (determination according to DIN 53199) of at most 25 g / 100 g of zeolite, preferably at most 10 g / 100 g of zeolite.
- the materials used according to the invention preferably contain less than 3% diatomaceous earth and the zeolites are not mixed with antibacterial cations 1 .
- particularly preferred building materials are building boards, in particular gypsum plasterboard or gypsum fiber boards, or plasters, in particular plasters for application to interior walls, particularly preferably decorative plasters, since here the air access is not impeded by the further decoration.
- the plasters preferably contain the gypsum phase as a binder.
- the plates are covered, preferably with cardboard or glass fleece. If desired, they are also perforated (so-called "perforated plates").
- a building board e.g. Stucco and zeolites are mixed and the finished plate is freed of excess water in a continuous dryer.
- the gypsum content is preferably at least 30% by weight, preferably at least 50% by weight, even more preferably 70% by weight or more, in each case calculated on the set mixture.
- the present invention also relates to the use of the building materials according to the invention for reducing indoor air pollutants.
- Air pollutants that can be successfully removed from the indoor air include formaldehyde, benzene, ammonia and tobacco smoke. Odors, such as the smell of fish, can also be reduced, as was demonstrated experimentally by the breakdown of triethylamine. Surprisingly, the air pollutants are not bound to the materials, but are broken down / decomposed so that the materials do not become saturated.
- the maximum permissible workplace concentration (MAK value) for formaldehyde is 600 ⁇ g / m 3 .
- the average formaldehyde content is 220 ⁇ g / m 3 .
- the WHO assumes a guideline for protecting health of 100 ⁇ g / m 3 .
- a value to be aimed for in apartments is about 60 ⁇ g / m 3 .
- An average benzene content in a smoking room is around 45 ⁇ g / m 3 at an air exchange rate of 0.5 changes / hour.
- the target value in apartments is ⁇ 10 ⁇ g / m 3 .
- the invention is illustrated by the following example.
- Gypsum building boards with 10% natural zeolites (native, ie not dewatered) with a maximum grain size of 200 ⁇ m and ad 50 value of 40 ⁇ m were laid out in a room with a normal climate, with 1.23 m 2 of gypsum board area per 1 m 3 room volume ,
- a respective harmful gas concentration with the harmful gases for aldehyde and benzene as well as with a harmful gas mixture from cigarette smoke was set by continuously supplying a defined harmful gas mixture.
- the air change rate of the respective mixture was 0.5 changes / hour, ie the pollutant mixture was completely renewed within two hours.
- the remaining pollutant value in the outflowing mixture was measured as the gas concentration. Due to the contact with the gypsum building boards, the harmful gases were largely broken down and there was a concentration of harmful gases in the system from the initial value (inflowing mixture) to the equilibrium value (outflowing mixture)
- the test series also found that the pollutants are not stored in the plasterboard, but are reactively converted into harmless compounds.
