Description
Technical field
The present invention relates to a kind of method of polypropylene hydrophilic modifying, particularly a kind of method of Solid-Phase Grafting of Methyl-Methacrylate hydrophile monomer.
Background technology
Polypropylene (PP) is one of the most widely used polymkeric substance, and current production rate is only second to the second largest resin of polyethylene (PE).The advantages such as it has with low cost, good mechanical performance, resistance toheat is good, chemical stability good, insulating property are good, but owing to there not being polar group in molecule, wetting ability is poor, has hindered it and has applied more widely.In order to overcome this shortcoming, polypropylene need to be carried out to hydrophilic modifying.
That the main method of polypropylene hydrophilic modifying has is polypropylene blending modified, surface treatment and body modification etc.Blend is that polypropylene modification industry common are one of effect means; this kind of method has the advantages such as with low cost, simple to operate, technology handiness is large; but processing condition are changeful, usually can cause the variation of system form, make the performance of blend that variation also occur.Mostly surface treatment is radiotreatment method, and as plasma body, gamma-rays etc., Kim etc., under different atmosphere, as water, vinylformic acid, allylamine, use plasma modification microporous polypropylene membrane.Result demonstration, although under water and acrylic acid atmosphere, film wettability of the surface increases significantly (contact angle is from 100 °-40 °), mechanical property severe exacerbation, this is because the etching that oxidation causes; In addition,, under allylamine atmosphere, the surface of film has produced thin barrier film.There is in addition report various polar groups to be introduced to the surface of film, use CO
2and NH
3cement Composite Treated by Plasma microporous polypropylene film, result shows, the surface of microporous polypropylene film can and corresponding wetting ability have significantly and improve, and compared with unmodified film, after cleaning, there is higher flux recovery and low pollution index.But the Cement Composite Treated by Plasma of different atmosphere is inevitable etching all, etching meeting causes to melt to be damaged and deposition; In addition, due to polar group adjustment member region or be hidden in microporous membrane inside, the lipophilicity of film can be recovered.In order to solve this two problems, people, by the fixing method of plasmaassisted, live with plasma body circle at microporous polypropylene film surface physics absorption Polyvinylpyrolidone (PVP) (PVP).Result demonstration, after modification, the contact angle of film is along with the obvious reduction that increases of fixing percentage of grafting, and the biocompatibility that modified membrane has had and protein intercept power, but on film surface, the structure of PVP cross-linked layer is difficult to sign.Meanwhile, excessive radiation meeting causes the strength decreased of polymkeric substance.Body modification mostly is grafting, block modified method etc., Shi H etc. proposes fusion-grafting methacrylic acid macrogol ester on polyacrylic molecular chain at " Preparation of PP-g-PEG by using partial preirradiated polypropylene as initiator andits properties ", the graft copolymer of gained also can be used as the antipollution properties-correcting agent effect of polypropylene screen, but, the complicated mechanism of fusion-grafting, and be attended by serious side reaction, easily cause polyacrylic degraded.
In addition, because the synthetic of amphipathic nature polyalcohol generally all need to carry out in solvent, therefore need with a large amount of solvents as reaction medium, the application of solvent not only can be given environment, has also increased production cost.Tang smokes etc. and to have proposed to use Solid-Phase Grafting of Methyl-Methacrylate vinyl pyrrolidone in " research of polypropylene grafted nitrogenous compound and antioxygen oil resistance thereof ", in literary composition, mention and carried out protection system with nitrogen, but the flow velocity of nitrogen is difficult to control, and nitrogen is not easy fully to contact with polypropylene, thereby have influence on degradation-resistant effect; In addition, what this article adopted is that vacuum system takes off benzene, and it is too quickly to heat, complicated operation inconvenience, condition harshness.Meanwhile, adopt stainless steel cauldron, system inside is easily heated inhomogeneous, and is difficult for fully mixing, and reaction has dead angle.
Summary of the invention
Technical problem to be solved by this invention is: in prior art, the synthetic of amphipathic nature polyalcohol generally all carries out in solvent, and the application of solvent has caused pollution to environment, has increased production cost; And in prior art, with Solid-Phase Grafting of Methyl-Methacrylate hydrophile monomer, produce the method for amphipathic nature polyalcohol, and complicated operation, efficiency is not high.
For solving this technical problem, and consider the theory of " Green Chemistry ", " green economy ", the technical solution used in the present invention is:
The invention provides a kind of polypropylene--hydrophilic monomer multipolymer, this multipolymer is to prepare by the method for solvent-free Banbury mixer solid phase synthesis.
The present invention also provides a kind of above-mentioned polypropylene--the preparation method of hydrophilic monomer multipolymer, and concrete steps are:
(1) take raw material according to following formula, the mass fraction of each raw material is respectively,
100 parts of polypropylene
Interfacial agents 5-30 part
Initiator 0.1-9 part
Hydrophile monomer 10-60 part
Oxidation inhibitor 0.1-0.5 part,
As preferably: polypropylene is Powdered polypropylene, and particle diameter is 50-150 μ m,
Further: polypropylene is the F401 trade mark polypropylene that Yangzi Petrochemical Co., Ltd of China Petrochemical Industry produces,
As preferably: interfacial agents is selected from benzene, toluene or dimethylbenzene,
As preferably: initiator is selected from dibenzoyl peroxide BPO, tertiary butyl peroxidation formyl TBP, Diisopropyl azodicarboxylate AIBN or dicumyl peroxide DCP,
As preferably: hydrophile monomer is selected from vinyl pyrrolidone NVP or hydroxyethyl methylacrylate HEMA,
As preferably: oxidation inhibitor is selected from antioxidant 1010 or antioxidant 1076;
(2) interfacial agents and polypropylene are mixed, carry out swelling operation;
(3) by the polypropylene of the swelling mistake of interfacial agents, initiator, oxidation inhibitor and hydrophile monomer, in Banbury mixer, carry out graft polymerization reaction,
As preferably: the temperature of reaction of graft polymerization reaction is 100-120 DEG C,
As preferably: the time that reaction is carried out is 1-3 hour;
(4) products therefrom is washed, purified with dehydrated alcohol, filtration drying, obtains polypropylene--hydrophilic monomer amphipathic nature polyalcohol.
The invention has the beneficial effects as follows:
The present invention adopts Banbury mixer solid phase grafting, without the synthetic polymkeric substance with amphipathic structure of solvent, there is no this problem of solvent contamination environment, is environmentally friendly synthesis technique.
Adopt the technique means of Banbury mixer graft polymerization, easy and simple to handle, reaction conditions is not had to too much restriction; By adding oxidation inhibitor to carry out protection system, there are two stirrers Banbury mixer inside, and mixing effect is good, and oxidation inhibitor can be contacted with material well, and system is heated evenly, and reacts more complete.
The present invention uses vinyl pyrrolidone NVP or hydroxyethyl methylacrylate HEMA as monomer, and monomer has carbon-carbon double bond, easily causes autohemagglutination, and grafted chain is lengthened, and increases hydrophilic radical, improves polyacrylic wetting ability.
