Description
Technical field
The invention belongs to environment-friendly engineering technical fields, are related to a kind of preparation method of material for air purification, in particular to
To a kind of marine ecology nanometer conch meal and its method for being used to prepare conch meal base material for air purification.
Background technique
With the fast development of shellfishery, beginning of this century annual output has broken through ten million ton, reaches 1200 by 2010
Ten thousand tons, wherein marine shellfish accounts for 96%.Researches show that 1 ton of shellfishes of every processing, generate 30%~70% shell waste.Shellfish
Product yield increases year by year, and the lower added value of shell causes its utilization rate to be hesitated to move forward, so that shell discarding amount is anxious
Increase severely and add, is discarded in seabeach, roadside for a long time, it has also become " the head disease " of shellfishery is that current coastal area urgently solves
Environmental problem certainly.The surcharge for improving shell, " can turn waste into wealth ", become the effective means for cracking this quagmire, simultaneously
It can promote the sound development of shellfishery, realize the win-win of ecological environment, economic benefit and social benefit.
Shellfish main component is calcium carbonate, accounts for full shell 95%, remaining 5% predominantly organic matter chitin, is a kind of natural
Biogenic mineral material.Be mainly used in early period craftwork manufacture, feed aquaculture, medicine aspect or added value it is low or
Dosage is few, and application has significant limitation.The resource utilization of shell waste is paid attention to both at home and abroad at present, changes in soil
Good dose, adsorbent, construction material, catalyst, biologic packing material, greasy dirt detergent etc. (CN201710050738,
CN201710127361、CN106883642A、CN201710164049、CN201611239926、CN201610062807、
CN106893556A it) obtains and significantly breaks through and develop.Conch meal can produce the opening structure of a variety of different function after processing,
With stronger adsorption capacity, exchange capacity and catalytic decomposition ability.There is large specific surface area, strong with the carrier of photocatalyst
The advantages that degree is high, property is stable and cheap.The current existing patent that material for air purification is prepared using shell as raw material, greatly
The multi-purpose substrate for making indoor coating is used directly as interior wall coating, and the advantage exploitation of shell itself is still inadequate.Such as patent
CN201710472733 discloses a kind of conch meal indoor air purification wall material and preparation method thereof, using conch meal as substrate,
Preparation temperature is low, main component CaCO3, surface area is poor, and largely mixes with other ingredients after being prepared into wall material, table
Area is big, strong adsorption advantage can not embody.Patent CN106883745A, CN106867288A, CN106883644A,
CN106620785A etc. discloses the shell powder interior wall paint of indoor fit-up harmful gas decomposition, and conch meal is only used as film forming coatings
In powder body material or filmogen and usage amount it is few, be doped with the expensive catalytic activity group such as nano zinc powder, graphene
Point, preparation process is complicated, cumbersome.
As can be seen that most of invention is only used conch meal as powder body material, there is no conch meal is fully utilized
The ability of the purification air of itself.It is provided by the invention activity shell preparation process, in addition to generation recyclable dust and
CO2Outside, no other pollutants generate, and waste consumption amount is high, avoids and generates secondary pollution in environmental applications.In addition, this
It has invented also abundant and has utilized clam shell feature and performance, using active shell as carrier, prepared nanometer shell composite photocatalyst material,
For effectively removing for indoor formaldehyde and volatile organic compounds.
Summary of the invention
Current indoor air purification material is at high cost, technical problem of absorption and discomposing effect difference to solve, and provides one
The technology of preparing of kind marine ecology nanometer conch meal base material for air purification.The present invention is directed to the special appearance structure of conch meal,
Such as 0.2~10 μm of microcellular structure rich in, good adsorption performance, contain the features such as abundant metallic element, exploitation has
The environmentally conscious materials of bioaffinity, for substituting traditional contaminated materials etc., for the neck such as air pollution treatment, catalysis, building
The comprehensive development and utilization of shell is realized in domain, and for solving city air pollution, while solving the marine environment of current sternness
Pollution problem.
The present invention proposes a kind of marine ecology nanometer conch meal, which uses following steps system
It is standby: shell being cleaned and is cleaned, ventilation, which is dried to moisture content, at 15~30 DEG C accounts for the 5~15% of raw material weight, is transferred to microwave
Heating furnace, microwave heating press 5~20 DEG C/S of heating rate, are warming up to 800~1100 DEG C of heating temperature, 1~5h of heating time；It is cold
But ball milling after, the particle size after conch meal ball milling are 100nm~5 μm, obtain nanometer conch meal.
The method that a kind of above-mentioned marine ecology nanometer conch meal is used to prepare conch meal base material for air purification, step is such as
Under: nanometer conch meal, sodium metasilicate and active constituent are mixed, heat-activated, obtains shell base nano material for air purification；Its
In, nanometer conch meal, sodium metasilicate and active constituent parts by weights composition are as follows: nanometer conch meal 85~90, sodium metasilicate 5~10 are living
Property ingredient 0~5.
Further, above-mentioned heat-activated condition is 100~300 DEG C, stirs 30~120min.
Further, above-mentioned active constituent is one of negative ion powder, tourmaline, medical stone or a variety of.
The invention has the advantages that shell is not necessarily to dry at high temperature after cleaning, naturally dry.Microwave heating
Rate is up to 60 DEG C/S, and capacity usage ratio is high, has the advantages that energy conservation and environmental protection.Obtained active nano conch meal, pattern are
Particle or sheet accumulation, particle or sheet reach Nano grade, and high-specific surface area imparts the extremely strong adsorption capacity of conch meal.
Nanometer conch meal, sodium metasilicate and active constituent mixing, can effectively reduce the reunion of active constituent, be dispersed in a nanometer conch meal
Surface.Oxides of metals such as Al, Cu, Fe, Mn, Sn, V present in conch meal itself have certain catalysis organic pollutant
The ability of degradation.Shell base nano material for air purification is made after being compounded with active constituent, it can be achieved that formaldehyde, benzene under room temperature
It is absorption and the half-light catalytic degradation of the indoor common polluted gas such as object.
