Description

Technical Field

[0001] This invention relates to the field of building materials technology, and more specifically to a formaldehyde-removing putty powder. Background Technology

[0002] Traditional interior wall putty powder is mainly used for wall leveling, offering limited functionality and failing to address post-renovation indoor air pollution issues such as formaldehyde, benzene compounds, and odors. While some existing putty powders offer functional benefits, their formaldehyde removal efficiency is low (typically less than 50%), negative ion release is minimal, and their odor removal effectiveness is limited. Furthermore, some products contain added chemical reagents that may cause secondary pollution. Therefore, there is an urgent need for an environmentally friendly, safe, and multifunctional putty powder to solve indoor air pollution problems. Summary of the Invention

[0003] In view of this, the present invention provides an environmentally friendly putty powder that can efficiently adsorb and decompose formaldehyde, eliminate odors, and continuously release negative oxygen ions, thereby improving indoor air quality and meeting the needs of wall leveling.

[0004] To achieve the above objectives, the present invention provides the following technical solution, which is composed of raw materials in the following weight ratios:

[0005] 8 kg of plant gum powder, 5 kg of cellulose, 3 kg of bentonite, 20 kg of aldehyde powder, 1 ton of heavy calcium carbonate, 500 kg of light calcium carbonate, and 75 kg of modified calcium hydroxide.

[0006] Preferably, in the above-mentioned formaldehyde-removing putty powder, the aldehyde-removing powder removes free formaldehyde through the synergistic effect of physical adsorption and chemical decomposition, with a formaldehyde removal rate ≥80%.

[0007] Preferably, in the above-mentioned formaldehyde-removing putty powder, the bentonite and modified calcium hydroxide form a porous structure for adsorbing and eliminating indoor odors.

[0008] Preferably, in the above-mentioned formaldehyde-removing putty powder, under the influence of humidity, the plant adhesive powder and mineral components ionize and release negative oxygen ions, with a release amount of 500-2000 ions per square centimeter.

[0009] Preferably, in the above-mentioned formaldehyde-removing putty powder, the construction ratio of the putty powder is as follows: the powder and water are mixed at a ratio of 1:(0.4-0.5), stirred into a uniform paste, and then applied in two coats, each coat being 1-2 mm thick.

[0010] Preferably, the above-mentioned formaldehyde-removing putty powder is suitable for formaldehyde concentrations greater than 0.5 mg / m³. 3 The interior environment includes children's rooms, elderly rooms, and fully furnished rooms.

[0011] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a formaldehyde-removing putty powder that has the functions of wall leveling, formaldehyde removal, odor removal and negative oxygen ion release, simplifies the construction process, does not contain formaldehyde and other harmful substances, passes the national standard test such as GB18582-2001, has stable negative oxygen ion release, can continuously improve indoor air quality and improve human respiratory health. Detailed Implementation

[0012] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0013] The putty powder is composed of the following raw materials in the following weight ratios: plant gum powder: 8 kg, cellulose: 5 kg, bentonite: 3 kg, aldehyde powder: 20 kg, heavy calcium carbonate: 1 ton, light calcium carbonate: 500 kg, and modified calcium hydroxide: 75 kg.

[0014] Function implementation principle:

[0015] Formaldehyde removal: The aldehyde removal powder uses a combination of physical adsorption and chemical decomposition to convert free formaldehyde into harmless substances, achieving a removal rate of over 80%.

[0016] Odor elimination: Bentonite and modified calcium hydroxide form a porous structure that adsorbs fishy smells, pet odors, and other household pollutants.

[0017] Negative oxygen ion release: The mineral components and plant gum powder in the formula ionize under the influence of humidity, releasing 500-2000 negative oxygen ions per square centimeter, simulating the air purification effect of the natural environment.
