Abstract
It is a kind of that the instant capacity peroxidating high-molecular copolymer pasteurization material that dispersing and dissolving speed existing for peroxidating high molecular material is excessively slow and is able to use under oily solution system as macromolecule disinfectant can be solved by elimination flake.
Description
Technical field
The present invention relates to water-soluble high-molecular material fields more particularly to a kind of instant capacity peroxidating high-molecular copolymer to disappear
Malicious material.
Background technique
As traditional pasteurization material, chlorine-containing disinfecting material effects mechanism is that hydrolysis generates hypochlorous acid molecule, utilizes secondary chlorine
The oxidation sterilizing of acid molecule.But when chlorine-containing disinfectant being used to sterilize, decomposited by hypochlorous acid molecule HCIO secondary
Chlorate ions (OCL-) easily form carcinogen chloroform (CHCL with impurities in water3) or trichlorophenol, so seldom making now
It is carried out disinfection with chlorine-containing disinfectant, and generallys use peroxide sterilants.
Peroxide sterilants have Strong oxdiative ability, and various microorganisms are very sensitive to it, can kill all microorganisms
It goes out.This kind of disinfectant includes hydrogen peroxide, Peracetic acid, chlorine dioxide and ozone etc..They the advantages of are after sterilizing in article
On leave no residue toxicity, non-carcinogenesis.Someone is researched and produced disinfectants with rich carboxylic high molecular material in recent years, such as:
Peroxidating acrylic acid (sodium salt), peroxidating maleic acid (sodium salt), methyl acrylic acid (sodium salt) and peroxidating fumaric acid (sodium
Salt), but above-mentioned peroxidating macromolecule pasteurization material all has a problem that be exactly that solution rate is slow, is not easy to disperse, causes to make
Used time is very inconvenient.It should be pointed out that peroxidating high molecular material cannot generally be used in oil-soluble system.
Currently, peroxidating macromolecule pasteurization material product is mostly in solid powder state, although there is good water solubility,
It is in use, since product water solubility is very good, one layer of hydration shell to be formed in conjunction with water at once after being immersed in the water, high score
Sub- pasteurization material wraps up, to hinder molecule inside macromolecule material particle in conjunction with water, is apparently formed
It " bubble " of white one by one or cries " flake ".Flake will greatly prolong the time of disinfectant once being formed.
A large amount of technology exists in the prior art for eliminating flake, copolymerization is substantially realized by addition dispersion aids
In object fish-eye number reduction (such as CN102471508A, CN1335859A, CN1813004A, CN1515595A,
CN103788305A etc.), however, there has been no document reports for enabling macromolecule pasteurization material rapid dispersion, being dissolved in water
In can eliminate the technology of " flake ", especially peroxidating macromolecule pasteurization material.
On the other hand, from molecular structure, a large amount of hydrophilic carboxyl, institute are contained in peroxidating high molecular material
With the disinfectant is difficult to apply in oleaginous system.How the compatibility of macromolecule pasteurization material Yu oil-soluble system is solved
It is problem to be solved.
Summary of the invention
In view of the above problems, it is an object of that present invention to provide one kind to solve peroxidating macromolecule material by eliminating flake
Expect that existing dispersing and dissolving speed is excessively slow and is able to use the instant capacity peroxide as macromolecule disinfectant under oily solution system
