Technical Field
The invention relates to the technical field of air fresheners, in particular to an adsorption material for a solid air freshener, application and the solid air freshener.
Background
Solid air fresheners, which are generally solid products obtained by adsorption of fragrances from porous solid materials, are commonly used in vehicles and in rooms. Solid materials with pores are various and include natural ores, natural plants, synthetic materials and the like. Common are zeolite, vesuvianite, ceramic, diatomaceous earth, gypsum, wood block, ethylene-vinyl acetate copolymer, silica gel, and the like. The density, pore size and how much of each material varies. The bigger the pore is, the less the adsorbed essence is, the faster the volatilization is, and the shorter the service time of the product is; the smaller and more pores, the more essence is adsorbed, the slower the volatilization, and the longer the product life.
The amount of essence adsorbed by the existing product is not much, and the service time is short. The vesuvianite has larger pores and medium density, and the weight ratio of the adsorbed essence (the weight of the adsorbed essence/the weight of the solid material is 100%) is about 10 percent; the zeolite, the ceramic, the diatomite and the gypsum have smaller pores and larger density, and the weight ratio of the adsorbed essence is 5-20%; the wood block has large pores and small density, and the weight ratio of the adsorbed essence is about 20 percent; the ethylene-vinyl acetate copolymer and silica gel have small pores and medium density, and the weight ratio of the adsorbed essence is 20-40%. The existing solid air freshener in the market has few adsorbed essence and short service time, and is usually provided with 2-8 massive solid fragrance bodies for prolonging the service time of products, so that the replacement is troublesome, each fragrance body needs to be sealed by an aluminum foil bag, the resource is wasted, and the experience of consumers is poor. Some solid adsorption materials can leave liquid essence on the surface after absorbing essence, even if cotton cloth is wiped dry, when the cotton cloth is held by hand, the liquid essence still can be stuck on the hand, and consumers experience bad when replacing, carelessly contact with paint surfaces, plastics and the like, and can also cause corrosion.

After compression molding, the whole solid adsorption material forms a large number of uniform micropore channels, and then slowly adsorbs a large amount of essence by soaking and is locked in micropores, and experiments prove that the adsorption material of the invention has the weight ratio of adsorption essence of 130-175%. After the liquid on the surface is wiped, the liquid in the adsorption material cannot permeate outwards, the surface is dry and free of liquid, and the essence in the adsorption material can permeate outwards continuously only after the essence on the solid surface is volatilized, so that the balance of the inside and the outside is achieved. The slow outward penetration and volatilization of the micropores leads to the use time of the solid air freshener product to be 3-5 times that of the similar product.
Specifically, examples 1 to 5 of the present invention provide an adsorbent material for a solid air freshener and a solid air freshener comprising the same, and specific compositions of the adsorbent material and weight ratios of essence adsorbed in the solid air freshener are shown in table 1 below.
In examples 1 to 5, the main powder used had a particle size of 0.03 μm to 100. Mu.m. The particle size of the bridging agent is 0.05-120 mu m, and the particle size of the main powder is smaller than that of the bridging agent.
Table 1 adsorption material composition and adsorption essence weight ratio for solid air fresheners of examples 1 to 5
The preparation method of the adsorption material for the solid air freshener provided by the embodiment of the invention comprises the following steps: adding a bridging agent into the main powder, and uniformly mixing; adding a release agent into the mixture, and uniformly mixing the mixture; adding a shaping agent, and uniformly mixing; finally, adding a binder, and uniformly mixing; and (3) performing compression molding to obtain the adsorption material for the solid air freshener (the weight of each adsorption material sample in the embodiment is 50 g). When the product is manufactured, the weight of the adsorption material can be set to be 1-50g or 50-100g according to the requirements according to different use places.
In table 1, the adsorbed fragrances of the different examples have different specific gravities. The difference in the weight ratio of the odor to the odor is related to the particle size of each raw material in the main powder, and the smaller the particle size is, the stronger the adsorption capacity is. When the particle diameters are the same, the more the silicon compound is, the higher the odor absorption specific gravity is.
Compared with the existing adsorption materials (the porous volcanic stone is relatively large, the density is medium, the weight ratio of the adsorption essence is about 10%, the porous zeolite, the ceramic, the diatomite and the gypsum are relatively small, the density is relatively large, the weight ratio of the adsorption essence is 5-20%, the porous wood block is large, the density is small, the weight ratio of the adsorption essence is about 20%, the weight ratio of the ethylene-vinyl acetate copolymer to the silica gel is small, the density is medium, and the weight ratio of the adsorption essence is 20-40%) of the solid air freshener in the market, the adsorption material provided by the invention utilizes the characteristic of a micropore structure, and the weight ratio of the adsorption essence is 130-175%.
