The present invention provides a kind of preparation methods of structure antimicrobial form flexible polyurethane foam material, include the following steps:
(1) the nano fluorine-contained polyalcohol of structure antimicrobial form water-based, polyether polyol with high activity 330N are weighed according to mass ratio
It with polyether polyol WANOL F3156, places it in reaction vessel, then chain extension containing guanidine hydrochloride is added by constant weight number
Agent, catalyst and foam stabilizer obtain component A after stirring 20~40s with the speed of 4000~6000rpm, according to parts by weight,
The composition of above-mentioned substance is as follows:
The structure of the chain extender of the present invention containing guanidine hydrochloride are as follows:
Wherein, R represents the alkyl of hydrogen atom or carbon atom 1~15；The integer that m is 0~15；The integer that n is 0~15；R is
1~20 integer.
The structure of the nano fluorine-contained polyalcohol of structure antimicrobial form water-based of the present invention is as follows:
RF is acrylic compounds fluoroalkyl monomer, and the acrylic compounds fluoroalkyl monomer is selected from acrylic acid tetrafluoro ethyl ester, third
Olefin(e) acid trifluoro ethyl ester, trifluoroethyl methacrylate, hexafluorobutyl acrylate, 2,2,3,3,3- pentafluoropropyl group acrylate, 2,
2,3,3- tetrafluoro propyl acrylate, 1H, 1H, 5H- octafluoro acrylate, acrylic acid -1,1,1,3,3,3- hexafluoro isopropyl
Any one in ester, R1 are diisocyanates, and R2 is polyester polyol, and R3 is antimicrobial form hydrophilic chain extension containing guanidine hydrochloride
Agent.
Polyether polyol with high activity 330N used in the present invention, polyether polyol WANOL F3156 are purchased from goodization chemistry respectively
Limited liability company and Wanhua Chemical Group Co., Ltd..
Catalyst of the present invention is triethylenediamine, N, N- dimethyl cyclohexyl amine, tetramethylethylenediamine, two laurels
The mixture of one or more of sour dibutyl tin or stannous octoate.
The foam stabilizer is the mixture of silicone oil, silicon-carbon type stabilizer or silicone oil and silicon-carbon type stabilizer composition.
(2) again using isocyanates as B component, A and B component mass ratio are 1:(0.46~0.52), it weighs B component and is added to
In container described in step (1), 15~30s is stirred with the speed of 4000~6000rpm, is subsequently poured into mold and is solidified, cures,
Up to a kind of structure antimicrobial form flexible polyurethane foam material.
Further, the isocyanates is toluene di-isocyanate(TDI) (TDI), '-diphenylmethane diisocyanate (MDI)
One or more of mixture.
Further, mold described in step (2) is 20cm × 10cm × 10cm Teflon mould, is first solidified
100~120s, then solidify 36h afterwards at room temperature.
Further, the structure antimicrobial form flexible polyurethane foam material, according to parts by weight, raw material composition and content
It is as follows:
Further, the structure antimicrobial form flexible polyurethane foam material, according to parts by weight, raw material composition and content
It is as follows:
Further, the structure antimicrobial form flexible polyurethane foam material, according to parts by weight, raw material composition and content
It is as follows:
Further, the soft bubble of structure flame retardant polyurethane, according to parts by weight, raw material composition and content are as follows:
Since soft polyurethane foam is a kind of material with porous structure, harmful micro- life such as enrichment of bacterial is easier in duct
Object, so this kind of material for polyurethane sponge, is easier at the antibacterial being conceived in its duct when carrying out antimicrobial treatment to it
Reason.In the prior art, antibacterial agent is only added in urethane raw by people, and this external-added antibacterial can only will at most resist
Microbial inoculum is evenly distributed in soft polyurethane foam, can not but accomplish that the antibacterial in duct is strengthened.
Antibacterial effect in the present invention passes through the nano fluorine-contained polyalcohol of structure antimicrobial form water-based and chain extension containing guanidine hydrochloride
Agent synergistic effect realizes that wherein the nano fluorine-contained polyalcohol effect of water-based, structure antibacterial has three: first is that in polyol resin
It is introduced simultaneously in molecular structure and contains guanidine hydrochloride and fluoro-containing group with antibiotic property, fluorine element is in surface tension effects in addition
Under easily towards surface layer migrate, easily reach the antibacterial synergistic effect in duct.Second is that since this nano fluorine-contained polyalcohol is pure
Water-base resin can either play diluting effect, and can generate with isocyanates environmentally protective wherein containing certain moisture to system
The foamable reaction of type, without adding other blowing promotors, to effectively overcome conventional foaming agents bring Heavy environmental pollution.
Third is that the particle size of this water-based fluorine resin is in 40nm or so, far smaller than traditional fluoropolymer resin (micron order),
Due to unique nano effect, so that this resin is easily uniformly dispersed in compound resin system, and forms firm connection, effectively
Solves the technical problem that antibacterial agent can not homogeneously disperse in fluoropolymer resin.In addition, the present invention is used containing guanidine hydrochloride
Hydrophilic chain extender is the basic material of the nano fluorine-contained polyalcohol of preparation structure antimicrobial form water-based in itself, is had with resin system
There is good compatibility, will not be precipitated, not only pacify but also antibacterial effect is played to system.
According to AATCC Test Method 100 (Counting alive microbial method) TZ/TO2021-9, to the structure in above-described embodiment
Antimicrobial form polyurethane sponge carries out antibacterial measurement, find its to the antibiotic rates of Escherichia coli and staphylococcus aureus >=
99.0%, show excellent bacteriostasis property.
The present invention is compared with prior art, and technological progress is significant.The present invention solves addition in the prior art
Technical deficiency present in type antisepsis and applied foam agent, provides that a kind of fungi-proofing property is good, performance is stable, safety and environmental protection,
And it is suitable for the preparation method of the structure antimicrobial form flexible polyurethane foam material of industrialized production.
