The invention discloses a deodorizing composition which comprises the following components in parts by weight: 3-15 parts of a photocatalyst, 3-10 parts of negative ion powder, 1-10 parts of a natural deodorizing material, 0.5-2 parts of a plant extract, 0.5-1 part of an antibacterial agent and 0-1 part of essence. The invention further discloses an application of the deodorizing composition. According to the deodorizing composition, the odor can be comprehensively and lastingly removed; in addition, a deodorizing technology is creatively combined with a paper technology, a cloth technology and a granular adsorbent technology, the deodorizing composition is applied to the fields of paper making, cloth making and granular adsorbents, and a novel indoor pollution control product which is low in price and convenient to use and can be used for lastingly adsorbing and decomposing the odor can be obtained.

The invention relates to a deodorant fragrance composition which comprises, in weight percent, 60%-70% of modified zeolite, 10%-15% of tourmaline, 8%-12% of deodorants, 5%-10% of plant essential oil,2%-5% of fragrance depositing agents and an appropriate amount of deionized water. A preparation process includes the steps: baking clinoptilolite at the temperature of 500-700 DEG C for 0.5-2 hours to obtain zeolite particles; grinding the zeolite particles to obtain zeolite powder; adding the zeolite powder into tetramethyl ammonium hydroxide; adding nano-silver particles and nano-titania particles; performing ultrasonic oscillating and stirring at the temperature of 90-120 DEG C for 0.5-1.5 hours; flushing obtained mixture with the deionized water; drying the mixture to obtain the modifiedzeolite; adding the deodorants, the plant essential oil and the fragrance depositing agents; stirring and mixing the modified zeolite, the deodorants, the plant essential oil and the fragrance depositing agents; adding the tourmaline and the deionized water; stirring the mixture to obtain a finished product. By the aid of a porous structure of the modified zeolite, the tourmaline, the fragrance depositing agents and the plant essential oil are adsorbed into pore passages, and long-lasting deodorization and faint scent emission are achieved.

The invention discloses an inorganic functional coating, the composition and parts by weight of which are as follows: 15-36 parts of white cement, 20-45 parts of ash calcium powder, 23-60 parts of heavy calcium powder, 8-16 parts of talcum powder, 5-16 parts of kaolin, 2-12 parts of metakaolin compound, 4-14 parts of diatomite compound, 3-12 parts of diatomite, 1-3.5 parts of fiber mixture, and 1-5.5 parts of auxiliary agent. Metakaolin compound includes metakaolin, mineral powder and negative oxygen ion powder, diatomaceous earth compound includes diatomaceous earth and tourmaline, fiber mixture includes lignin fiber and hypromellose, negative oxygen ion powder includes tourmaline , hexacyclic stone, rare earth oxides, monazite, microcrystalline mother powder any two or more. The invention can release negative oxygen ions, absorb and decompose formaldehyde and VOC, settle PM2.5, remove peculiar smell, purify air, and make the concentration of negative ions released in the room reach 1000ions / cm 3 Above, to achieve a very fresh air quality, to meet the environment required by the healthy life of the human body.

A microcapsule formaldehyde-removing agent and a preparing method thereof in the field of air purification are disclosed. The removing agent includes a core material and a wall material in a mass ratio of 1:2-6. The core material includes, by weight, 5-10 parts of tea polyphenols, 2-5 parts of aloe extract liquid, 3-5 parts of bracket plant extract liquid, 2-4 parts of Ottelia alismoides extract liquid, 5-10 parts of nanometer carbon black, 2-5 parts of nanometer silver, 2-3 parts of grape seed oil, 1-2 parts of cymbopogon citratus essential oil, 0.5-1 part of lavender essential oil, 0.5-1 part of eucalyptus essential oil, 3-10 parts of an emulsifier, 1.5-3 parts of a co-emulsifier, 1-3 parts of a dispersant and 1 part of a pH stabilizing agent. Uniformly dispersed formaldehyde-removing agent liquid particles are covered with a natural polymer film-forming material to form micro immobilized particles. Plant active components and the nanometer carbon black in the core materials are slowly released by passing through the wall material to remove formaldehyde in air, thus achieving an objective of removing formaldehyde for long term.
