The third object of the present invention is to provide the cotton class fabric surface of the releasable negative oxygen ion antimicrobial of above-mentioned Low emissivity
The application method of coating.
Technical solution: in order to achieve the above object of the invention, the present invention is specifically achieved like this: a kind of Low emissivity can be released
Put the cotton class fabric surface covering of negative oxygen ion antimicrobial, the component including following parts by weight: 2 ~ 20 parts of rare earth anion
Material, 5 ~ 20 parts of sodium sulphate, 0.1 ~ 2 part of bleeding agent, 0.1 ~ 2 part of stabilizer, 10 ~ 40 parts of adhesive and 3 ~ 10 parts
Crosslinking agent.
Wherein, the rare earth anion material includes the mixture of metal oxide and salts substances, component have manganese,
Zinc, iron, magnesium, radium, thorium, copper, aluminium, gold；Choose the mixing Tourmaline carbonated rare earth from north of China Xitu Hi-Tech company.
Wherein, the bleeding agent is fatty alcohol polyoxyethylene ether.
Wherein, the stabilizer is sulfuric ester.
Wherein, described adhesive is polyacrylate.
Wherein, the crosslinking agent is methyl-etherified hexamethylol melamine resin.
The method for preparing the cotton class fabric surface covering of the releasable negative oxygen ion antimicrobial of above-mentioned Low emissivity, including following step
It is rapid:
(1) stand-by by formula measurement each component；
(2) rare earth anion material is carried out being crushed to micron order, with the dissolving with hydrochloric acid of molar concentration 2 ~ 10%, the addition of hydrochloric acid
Amount is 5 ~ 6 times of rare earth anion material；
(3) lysate obtained by step (2) is filtered, filter residue and filtered fluid are collected for use respectively；
(4) sodium sulphate that molar concentration 5 ~ 10% is added into step (3) resulting filtered fluid is precipitated, sodium sulphate additional amount
It is the 25 ~ 35% of filtered fluid weight, sediment collection is handled, the dense progress high temperature evaporation concentration of filtrate, and temperature is controlled at 85 ~ 95 DEG C,
It is evaporated to solid content accounts for liquid fraction 40% or less；
(5) the resulting filter residue of step (3) and step (4) resulting concentrate are mixed, is made into mixed liquor, mixed liquor is added
The distilled water of quality 30 ~ 60%, and bleeding agent is added and stabilizer is configured to suspension；
(6) colloid mill is added in the resulting suspension of step (5) and carries out defibrination, controlling solia particle diameter in slurry is 20
~800nm；
(7) slurry obtained by step (6) and crosslinking agent and adhesive are mixed, is prepared into reaction solution.
The application method of the cotton class fabric surface covering of the above-mentioned releasable negative oxygen ion antimicrobial of Low emissivity, takes surface covering
The catalyst of its quality 0.1 ~ 1% is added in reaction solution, using coating processes or dips technique and is reacted with cotton class fabric, controls
150 ~ 170 DEG C of reaction temperature, react 30 ~ 60s.
Wherein, the catalyst is selected from phosphoric acid, sulfuric acid or organic acid.
The principle of the present invention are as follows: 1, using the textile products overwhelming majority such as bedding, underwear use cotton, viscose, tencel
Equal celluloses and its blended fabric, and all active methylol functional groups in cellulosic molecule formula, the friendship used with the present invention
Methylol, amino, carboxyl, hydroxyl in the molecules such as connection agent, adhesive chemically react, and connect skill reaction to be formed, make two
Person combines together, and permanent water-fastness cotton class fabric is made.2, it is used herein to anion material be taken from rare earth material
Material contains a large amount of structural water molecules in these materials, can be with crosslinking agent, the methylol of adhesive, amino, carboxyl, hydroxyl etc.
It chemically reacts, the two is made to combine together, so that anion material becomes a part of crosslinking agent, adhesive.3, of the invention
Anion material be taken from rare earth material, these materials are the Determination of multiple metal elements such as Mg, Fe, Al, Cu, Mn, Zn and rare earth gold
Belong to oxide etc. and a small amount of Ra(radium-226 of composition) etc. radioactive elements.It is easy using rare earth metal and its oxide
Dissolve self-characteristic react with the generations such as hydrochloric acid, so that individual Ra ion can be obtained, and occur the Ra after dissolution is reacted from
Easily with carbanion, sulfate ion generates reaction, produces sediment not soluble in water son, and sufficiently being filtered can be negative
Ra in ionic material is dispelled.4, the anion material used in the present invention forms nanosizing powder by dissolution, grinding, can be with
Into crosslinking agent, adhesive it is intermolecular, by these macromoleculars wind wrap up, to form firm be coupled with fiber molecule.
If 5, radioactivity radium content is excessive, alpha ray, internal body and outside of the alpha ray of long-term low dose to organism will be generated
It can generate compared with major injury, so country has formulated construction material emission lines nucleic stringent mandatory standard GB 6566-
2010, the inside and outside irradiation limitation of the radionuclides such as clear stipulaties Ra in standard.The present invention is soluble in using the compound of Ra
Acid, the Ra ion of production is easy again and carbanion, sulfate ion generate feature not soluble in water, carries out to radioactivity Ra
Removal and separation.
The utility model has the advantages that the present invention, compared with traditional technology, cotton class fabric obtained has the function of permanent releasing negative oxygen ion
Can, and can effective bactericidal, up to 95% or more, the negative oxygen ion concentration of excitation eliminates antibiotic rate up to 3500/cm3
Radioactive element Ra-226 largely ensure that the security feature of product.
