Coating classification: nano interior wall anti mildew environmental protection coating

Core tip: Product Introduction: Nano zinc compound anti mildew interior wall emulsion paint is a kind of interior wall emulsion paint with anti-bacterial and anti mildew effect, which uses nano zinc compound as filler Nano zinc compounds have a certain contribution to the storage stability of the coating, the bactericidal and anti mildew effect of the coating, and the negative ions can be released continuously after the coating film is formed, which is an ideal environmental protection building coating However, the antibacterial effect of most nano materials is limited by UV, oxygen, water and other conditions, and these materials are easy to agglomerate in the coating system Therefore, the interior wall coating with conventional nano materials can not be effectively resistant to sunlight Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Coating home news: Product Introduction: nano zinc compound anti mildew interior wall emulsion paint is an anti-bacterial and anti mildew interior wall emulsion paint made by using nano zinc compound as filler Nano zinc compounds have a certain contribution to the storage stability of the coating, the bactericidal and anti mildew effect of the coating, and the negative ions can be released continuously after the coating film is formed, which is an ideal environmental protection building coating However, the antibacterial effect of most nano materials is limited by UV, oxygen, water and other conditions, and these materials are easy to agglomerate in the coating system Therefore, the interior wall coating with conventional nano materials can not get effective antibacterial effect in the sunlight, and the simple preparation method can not make the nano particles disperse stably in the coating, resulting in the nano effect can not play At present, silver, zinc and copper ions are the main antimicrobial agents, among which anions have the best antibacterial effect However, anions are easy to change color and high cost The inorganic antibacterial agents with moderate price generally use zinc oxide or powder materials that are in line with zinc oxide For example, the composite antibacterial agents with good antibacterial effect prepared by zinc oxide and silver salt can be used in different materials and environments, but the anions in the water-based coating face the problem of discoloration Due to the high solubility of zinc oxide in water, it has high selectivity for dispersant, thickener and pigments and fillers Due to the influence of pH value, the stability of the coating is poor, which also limits its promotion in the coating Zinc sulfide has good antibacterial and mildew resistance, good stability, and is not easy to cause physiological changes when mixed with zinc oxide This product uses the mixture of nano zinc oxide and zinc sulfide to be added in the latex paint as the antibacterial and anti mildew component Mechanism: as we all know, zinc, like silver and copper, is a natural dissolving inorganic antibacterial agent The dissolved zinc ion combines with cell membrane and membrane protein, and prevents bacterial reproduction by damaging the three-dimensional structure of cells In addition, nano zinc oxide is a typical photocatalyst with photocatalytic activity The surface of nano particles can produce strong oxidizing negative ions (oxyhydrogen radicals and peroxides), directly damage bacterial cells, and play a role in sterilization, mildew prevention and deodorization Nano zinc oxide has a long-lasting bactericidal function because it depends on the dissolving and dissolving of zinc ions and photocatalyst catalysis Nano zinc oxide has strong antibacterial activity against Gram-positive bacteria such as Staphylococcus aureus, MRSA, Pseudomonas aeruginosa, pneumonia bacteria, Escherichia coli, Salmonella and other gram-negative bacteria Nano zinc compounds: nano zinc oxide is a new inorganic functional material developed in recent years, which is a particle with a particle size of 1-100 nm Due to the refinement of particle size and the sharp increase of specific surface area, nano ZnO particles have obvious surface and interface effects, quantum size effects, volume effects, macro quantum tunnel effects, high transparency, high dispersion and other characteristics Compared with ordinary ZnO, nano ZnO particles have excellent optical activity, electrical activity, sintering activity and catalytic activity Therefore, nano ZnO particles in magnetic field It has a series of excellent physical and chemical properties, and has a broad application and development prospect in fine ceramics, UV shielding, piezoelectric materials, photoelectric materials, high-efficiency catalytic materials, magnetic materials, etc Zinc oxide crystal is wurtzite structure, belongs to hexagonal crystal system, and is polar crystal In the crystal structure of zinc oxide, the atoms of zinc are closely stacked in six directions There are four oxygen atoms around each atom of zinc, forming a Zn-O coordination tetrahedron structure The anionic coordination polyhedron in the crystal becomes the unit to study the basic structure of crystal structure and morphology The projection of zn-0 on the C (ooo1) surface is shown in the figure In one cell layer, zn-o2-can be divided into two layers: upper and lower, two tetrahedrons The corresponding relationship between the top angle and face of the upper and lower tetrahedron and the hexagonal column is the same The top angles of the upper and lower layers of Zn-O ~ tetrahedron point to the negative polar plane of the crystal The positive polar plane is parallel to the tetrahedral plane, and the distribution of Zn and O atoms in the c-axis direction is asymmetric, showing the characteristics of polar crystal Features: Z multiple functions: the antibacterial, mildew and deodorization functions of nano zinc oxide are reflected in two aspects: one is the protection of the coating itself after production, transportation, storage and use; the other is the coating surface after coating, which has a killing effect on bacteria In addition, nano zinc oxide also has the functions of shielding ultraviolet, anticorrosion, flame retardant and removing formaldehyde odor Good Z transparency: after surface treatment, nano zinc oxide is added to different kinds of coatings, the degree of particle aggregation is improved, the dispersion is uniform, the coating formed has good transparency, and the bottom color is basically not affected Z high safety: nano zinc oxide is non-toxic and tasteless, no harmful gas volatilization Z stability is good: high temperature resistance, long-lasting sterilization effect, especially under light conditions Low use cost of Z: low use cost of nano zinc oxide Ingredients: composition mass fraction /%
