Description

A kind of function of removing formaldehyde carpet material and preparation method thereof
Technical field
The invention belongs to technical field of function materials, it is related to a kind of function of removing formaldehyde carpet material and preparation method thereof.
Background technique
Formaldehyde deeply affects the health of people as a kind of toxic gas, and the formaldehyde in carpet is even more directly to people Body has an impact.Existing formaldehyde removal technology is mostly the mode of activated carbon adsorption, absorption of the active carbon to macromolecule gas Ability is stronger, but the limited sorption capacity of the formaldehyde for small-molecular-weight, and there are problems that formaldehyde desorption causes secondary pollution.
Manganese dioxide is with a wide range of applications as a kind of efficient catalytic material in purifying formaldehyde field.Manganese dioxide The particle size of particle greatly influences its catalytic activity.Existing manganese dioxide technology of preparing mainly passes through chemical synthesis side Method is made using the synthetic reaction of potassium permanganate and manganese sulfate, and the partial size usually prepared is in 30~1000nm, and such partial size The all solid constructions of the particle of size, the small (20~70g/m of specific surface area2), the manganese dioxide of such partial size has certain Catalytic performance, but from quick catalysis decomposing formaldehyde, there are also very big rooms for promotion, and realizing quick catalysis decomposing formaldehyde will be very big Reduce threat of the formaldehyde to people's health.Patent CN107537473A discloses a kind of nanometer of room temperature catalytic oxidation formaldehyde Mn catalyst and preparation method thereof promotes its catalytic efficiency by loading the method for manganese dioxide on oxide carrier, But due to its preparation or common manganese dioxide, the practical formaldehyde efficiency that is catalyzed is only 82%.
Therefore, study it is a kind of can quickly, the nano manganese oxide of efficient catalytic decomposing formaldehyde and be applied to preparation and have The carpet material of function of removing formaldehyde has a very important significance.
Summary of the invention
Present invention aim to address carpet materials in the prior art not to have the problem of function of removing formaldehyde, provides one kind and removes Formaldehyde function carpet material and preparation method thereof.
In order to achieve the above objectives, the scheme that the present invention uses is as follows:
A kind of preparation method of function of removing formaldehyde carpet material, using potassium permanganate and manganese salt as Material synthesis manganese dioxide During the entire process of, processing reaction system is set using ultrasonic nano makeup, and water is added into reaction system before starting the reaction Property acrylic monomers and carpet substrate material, while with the rate fast cooling of 9 DEG C/min or more after reacting 10~15min After to -10 DEG C or less, carpet substrate material is taken out, is dried under the conditions of 120~170 DEG C of temperature and function of removing formaldehyde carpet is made Material.
The present invention joined aqueous acrylamide acid monomers and carpet substrate material in the synthesis process of manganese dioxide, and aqueous third Acrylic monomer and carpet substrate material are added before starting the reaction, with the progress of reaction, constantly there is manganese dioxide generation, Manganese dioxide and aqueous acrylamide acid monomers can be directly uniformly distributed on carpet substrate material, manganese dioxide after synthesis process It is weaker in conjunction with carpet substrate material, it is easy to fall off, at this time again through 120~170 DEG C of drying and processing, in the process aqueous third Acrylic monomer can occur polymerization and form polyacrylic resin, and manganese dioxide is firmly adhered to be made on carpet substrate material and is removed Formaldehyde function carpet material；
The present invention synthesizes the method for manganese dioxide compared with the manganese dioxide synthetic method of the prior art, and the main distinction is such as Under:
1) it increases ultrasonic nano makeup to set, does not have in the existing reaction process for preparing manganese dioxide while ultrasound being added to receive Rice makeup is set, and the present invention sets processing reaction system using ultrasonic nano makeup, so that the partial size of nano-manganese dioxide particle is lower than The partial size that the manganese dioxide nano particle of reaction system preparation is set in ultrasonic nano makeup is not added, this is conducive to promotion manganese dioxide and receives The specific surface area of rice grain increases its reaction site with gas, to greatly improve its purifying formaldehyde performance；
2) fast cooling is to -10 DEG C hereinafter, existing reaction is all after the reaction was completed again slowly temperature after reacting a period of time Degree lowers, and fast cooling is conducive to terminate reaction rapidly, and the manganese dioxide particle generated is prevented to be further enlarged, this is because Manganese dioxide powder is known from experience as the progress of reaction is gradually grown up in reaction process, and temperature is the necessary condition for promoting it to react, Moment, which reduces temperature, can inhibit the progress of reaction, further growing up for powder be prevented, after fast cooling, in established titanium dioxide Manganese particle internal residual has a large number of water molecules, the manganese dioxide of preparation is put under normal temperature environment after liquid water evaporation will form it is more Pore structure improves the specific surface area of manganese dioxide；If temperature does not reach -10 DEG C hereinafter, reaction still slowly progress, meeting Cause final partial size bigger than normal.
