Abstract

The invention discloses a mineral wool decorative acoustic board with the function of eliminating formaldehyde, which comprises a mineral wool board matrix, wherein the mineral wool board matrix is coated with a layer of coating; the coating contains 1 to 10 percent of photocatalytic material (weight percentage); and the photocatalytic material is copper-doped nanometer titanium dioxide. The mineral wool decorative acoustic board can quickly, efficiently and durably eliminate the formaldehyde under the condition of light or no light indoors, not only has good purification effect, but also needs simple conditions for the purification, and is suitable for various occasions.

Description

Mineral wool decorative acoustic board with function of eliminating formaldehyde
Technical field
The present invention relates to a kind of mineral wool decorative acoustic board, belong to architectural decoration material field with function of eliminating formaldehyde.
Background technology
Since the nineties in 20th century, the room air pollution healthhazard becomes one of important environmental problem of national governments and public attention, and wherein the formaldehyde problem is particularly outstanding.Formaldehyde is very harmful to health, when the concentration of formaldehyde reaches 0.1mg/m 3The time, formaldehyde will impact health, and comprising stimulates eyes to shed tears, cause asthma etc.Concentration of formaldehyde is higher than 50mg/m 3The time can cause grievous injury, as pneumonia, pulmonary emphysema, even dead.If contact formaldehyde for a long time, can cause diseases such as carcinoma of mouth, cutaneum carcinoma, lung cancer, leukaemia.The formaldehyde amount is less than 0.08mg/m in " formaldehyde sanitary standard in the indoor air " regulation room 3, but concentration of formaldehyde average out to 0.2mg/m behind the general house decoration 3, reach as high as 0.81mg/m 3, seriously exceed standard.Along with the reinforcement of people's environmental consciousness, and, strengthen the control in room air pollution source and administer particularly important the raising that indoor environment requires.
Mineral wool decorative acoustic board is widely used in the various building owing to having ornamental preferably and sound absorbing capabilities.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of mineral wool decorative acoustic board with function of eliminating formaldehyde, has the effect of eliminating formaldehyde under the irradiation of natural daylight well.
In order to address the above problem, the invention provides a kind of mineral wool decorative acoustic board with function of eliminating formaldehyde comprises: the mineral wool board matrix, scribble one deck coating on this mineral wool board matrix, contain 1~10% catalysis material in the described coating, described percentage is weight percentage.
Preferably, described catalysis material is the copper doped nano titanium dioxide.
Preferably, the quantity for spray of described coating is 200~300g/m 2
The present invention can rapidly and efficiently eliminate formaldehyde enduringly under indoor light or unglazed situation, not only have good clean-up effect, and it is simple to purify conditions needed, is fit to very much various occasions and uses.
The specific embodiment
