Problems solved by technology

[0003] Chinese patent document CN105948675A discloses a kind of heat-reflecting and heat-insulating diatom mud for indoor use. , silica, dispersant and thickener, the product has excellent heat reflectivity, antibacterial, waterproof, corrosion resistance and stability, high bonding strength, short curing time, convenient construction and high efficiency; however The redispersible rubber powder used in this method belongs to organic latex powder. This chemical adhesive is firmly bonded, but it is easy to block the micropores and lose the breathing and filtering effect of diatom mud. In addition, VOC substances such as formaldehyde may also be released. Not really a green interior wall material
However, the current inorganic adhesives generally have low strength, poor water retention, easy powder removal, and cannot be used alone; while the wood fiber variety is single, easy to absorb water and corrode, and the reinforcement effect is not high enough.

Embodiment 1

[0022] The present invention adopts pregelatinized starch, a pure natural plant green adhesive that is instant in cold water, high in bonding strength, cheap and good in quality, and is compounded with cellulose ether to obtain a new type of inorganic gelling system; Magnesite fiber is a kind of natural fiber raw material that is harmless to the human body. Our reserves rank first in the world. It has a smooth hand feeling, rich fibers, and good splitting, hydrophilicity and water dispersibility. Brucite is formed under alkaline conditions and has good alkali resistance, so it is especially suitable for diatom mud reinforcement construction with high alkali content. Its hydrophilicity is also conducive to the improvement of diatom bonding and water retention properties, making it have high tensile and crack resistance properties and fatigue resistance.

[0023] In this embodiment, the silicon dioxide content in the diatomite is ≥90%, the particle size of heavy calcium and gray...

Abstract

The invention discloses a brucite fiber reinforced and toughened diatom ooze material and a preparation method thereof. The preparation method is simple to operate, raw materials are low in price and environment-friendly, and the industrialization is easy to realize. The diatom ooze material, prepared by the technical scheme disclosed by the invention, has the beneficial effects of humidity regulating, sound insulation and noise reduction, fireproofing and flame resisting, air-purifying, salubrity and the like.

Description

technical field [0001] The invention relates to an environment-friendly building interior wall material, in particular to a brucite fiber reinforced and toughened diatom mud material and a preparation method thereof. Background technique [0002] The main raw material of diatom mud is diatomite. Since the surface of diatomite is rich in fine pores and a small amount of mesopores and micropores in the interior, it has a unique multi-level pore structure. The specific surface area of ​​diatomite can reach 65m 2 / g, light and non-toxic, powder bulk density is only 0.34-0.65g / m 3 . Therefore, it has strong adsorption and can be used as filter aid, adsorption, thermal insulation and catalytic carrier material. Since its main component is amorphous silicon dioxide (SiO 2 nH2O), so it also has the advantages of good thermal stability, flame retardancy, acid resistance and corrosion resistance. Thanks to its multi-functional environmental protection function of anti-mold and an...
