Description
Technical field
The present invention relates to a kind of preparation method of antibacterial agent, especially a kind of preparation method of paper grade (stock) antibacterial new material.
Background technique
Sheet paper products are being lived, packaging, play irreplaceable role, sizable a part of paper product in office
In use with the direct physical contact of user.With the raising gradually of living standards of the people, people are for paper phase
The health of pass is also increasingly paid close attention to.Meanwhile under wet environment, sheet paper products mould easy to breed is damaged.
CN103866644B discloses a kind of antibacterial agent and preparation method thereof, and the invention belongs to pulp technology for making paper.This is anti-
Microbial inoculum is made by containing the following parts by weight: double 20-30 parts of the octadecyldimethyl ammoniums of 40-60 parts of Phenoxyethanol, bromination,
10-15 parts of polyethylene glycol, 5-10 parts of ethylene glycol, 5-10 parts of hyaluronic acid, 2-5 parts of glycerol trioleate.
CN102587210B discloses a kind of preparation method that paper grade (stock) antibacterial agent is prepared with oil-tea camellia husks.Its feature exists
In: 10 parts by weight oil-tea camellia husks particles are added in 25~30 parts by weight glutaraldehyde water solutions, 350~400 weights are added in stirring
Part concentrated hydrochloric acid is measured, reacts 4h at 60~75 DEG C；0.5~5 parts by weight silver, zinc or copper metal compound solid is added, after dissolution
Continue stirring 4~12 hours；Filtering, washing filter residue to neutrality filter residue are added in the lye or reducing agent of 5 parts by weight, 40
0.5~3h is stirred to react at~80 DEG C；Filtering, washs filter residue to neutrality, filter residue dry oil-tea camellia husks base at 40~80 DEG C
Papermaking antibacterial agent.
Mostly when leaving the factory by high-temperature sterilization, ultraviolet radiator radiometric method sterilizes to eliminate paper existing paper industry
Bacterium on, but paper is because its frivolous characteristic is not easy to cause bacterium uniformly complete elimination, while being also temporary solution
It does not effect a permanent cure, cannot guarantee the health of paper surface for a long time；And current majority is used for the Antibacterial Products of paper antibacterial, is mostly used
Silver or other compositions are unsuitable for contacting human body or the poor dispersion in paper pulp for a long time, distribution is not as antibacterial agent
Cause bactericidal effect limited.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of preparation methods of paper grade (stock) antibacterial new material.It is prepared
Method is realized by following steps:
By weight, in a kettle, 2- hydroxyethyl ether cellulose, carboxyamino imidazole nucleus thuja acid is added, 6- chlorine is rattled away
Piperazine -3- formic acid, [carboxymethyl group-(2- hydroxy-5-methyl base-benzyl) amino] acetic acid, citric acid, dibutyl dithiocaarbamate
Nickel, 7% sodium hydroxide and 12% urea mixed solution are warming up to 80-95 DEG C, react 4-8h, then benzene first is added into product and narrows
Ago-Gel, neopelex stir 1-3h at a temperature of 80-95 DEG C with the revolving speed of 200-400rpm to get arriving
Paper grade (stock) antibacterial new material.
The 2- hydroxyethyl ether cellulose, carboxyamino imidazole nucleus thuja acid, 6- chlorine pyridazine -3- formic acid, [carboxymethyl group -
(2- hydroxy-5-methyl base-benzyl) amino] acetic acid, citric acid, nickel dibutyl dithiocarbamate, 7% sodium hydroxide and 12% urine
Plain mixed solution, quality amount ratio are 2- hydroxyethyl ether cellulose: carboxyamino imidazole nucleus thuja acid: 6- chlorine pyridazine -3- formic acid:
[carboxymethyl group-(2- hydroxy-5-methyl base-benzyl) amino] acetic acid: citric acid: nickel dibutyl dithiocarbamate: 7% hydrogen-oxygen
Change sodium and 12% urea mixed solution=100:1-3:2-5:0.5-1.5:1-2.5:20-40:80-180.
The benzene first narrows Ago-Gel, and quality dosage is the 1-3% of 2- hydroxyethyl ether cellulose.
The neopelex, quality dosage are the 1-3% of 2- hydroxyethyl ether cellulose.
The 2- hydroxyethyl ether cellulose, carboxyamino imidazole nucleus thuja acid, 6- chlorine pyridazine -3- formic acid, [carboxymethyl group -
(2- hydroxy-5-methyl base-benzyl) amino] acetic acid, citric acid, nickel dibutyl dithiocarbamate, benzene first narrows Ago-Gel,
Neopelex is commercial product.
Beneficial effects of the present invention:
Present invention paper grade (stock) antibacterial new material produced, it is good with the cellulose compatibility of paper grade (stock), in paper pulp
It is uniformly dispersed.Excellent in sterilization effect, the bactericidal effect duration is longer, and harm to the human body is small, not will cause heavy metal element pair
The discharge of environment and human body.
