Nano-whisker-reinforced multifunctional diatom ooze coating

Abstract

The invention relates to a nano-whisker-reinforced multifunctional diatom ooze coating. The nano-whisker-reinforced multifunctional diatom ooze coating is characterized in that 30 to 65wt% of diatomite, 0.5 to 2.5wt% of tetrapod-like nano-zinc oxide whiskers, 10 to 16wt% of superfine magnesium hydroxide, 5 to 15wt% of at least one crystalline aluminum salt, 10 to 40wt% of quartz sand, 0.5 to 1.5wt% of hydroxyethyl cellulose, 2 to 4.2wt% of one or two inorganic pigments and 0.5 to 3wt% of calcium hydroxide are mixed into the nano-whisker-reinforced multifunctional diatom ooze coating at a rotation rate of 500 to 800rpm. The nano-whisker-reinforced multifunctional diatom ooze coating has functions of resisting mildew and bacteria, purifying air in a room, and adjusting humidity. Compared with like products obtained by the existing technology, the nano-whisker-reinforced multifunctional diatom ooze coating has the advantages of strong adhesion to a wall surface, good durability, no falling-off of powder, no color fading and no cracking and falling-off, and is suitable for build interior decoration of airports, hospitals, office buildings, conference centers, hotels, villas, high-grade residential areas and entertainment places, and inner wall decoration of public places having forced flame-resistance requirements.

Description

technical field [0001] The invention relates to the technical field of interior decoration coatings, in particular to a nano-whisker-enhanced multifunctional diatom mud coating. Background technique [0002] Diatom mud paint is a new type of functional wall decoration environmental protection material developed in recent years. Its main component is diatomite. Diatomite is the remains of diatom lower plants that grow in oceans or lakes under certain geological conditions. The formed non-metallic mineral has a huge specific surface area, porosity and chemical inertness due to its unique Si-O, Al-O ordered microporous structure. Therefore, it has certain anti-mildew and anti-bacterial properties when used in building decoration materials. , Excellent function of adjusting humidity, purifying indoor air, absorbing formaldehyde, aromatic hydrocarbons and other harmful gases, it is a new type of environmentally friendly decoration material. [0003] The application of diatom mud...

AI Technical Summary

Problems solved by technology

Chinese patent 200910210892.7 discloses a kind of environment-friendly diatom mud wall material powder, wall material and preparation method thereof, this wall material mainly uses inorganic materials such as diatomite, kaolin, sepiolite, vermiculite powder, has better It has the effect of purifying air, absorbing moisture and deodorizing, but due to the poor adhesion between inorganic materials, there are technical problems that the coating is easy to powder and fall off after construction on the building wall. In order to solve this problem, organic Colloidal substances, due to the strong odor of residual solvents of such substances, they are easy to block the pores of diatomite, which reduces the environmental protection function of diatom mud coatings to a large extent, and the biodegradation rate of such organic colloidal polymers over time accelerated, resulting in poor paint durability

In addition, this kind of wall material does not have the function of decomposing harmful gases such as formaldehyde. From the perspective of the development trend of diatom mud coatings, the development of multi-functional, high bonding strength and good durability diatom mud coatings will be the first choice for architectural decorative coatings. The future direction of the industry
