The PVC paste resin for preparing medical gloves of domestic production at present is during plasticized paste configuration is carried out, mistake
Filter link is difficult, and the rate of filtration is slow, and the situation of resin adhesion screen cloth often occurs, needs manually to carry out aiding in clearly when serious
Reason.In addition, when carrying out the preparation of medical gloves by infusion process, uneven distribution that PVC paste resin adheres on mould,
PVC gloves broken hole is more made from causing, and qualification rate is low, is unable to reach the standard of medical gloves.
Those skilled in the art pass through multiple experiment and analysis, the existing commercially available Welvic for preparing medical gloves
Electrostatic between resin particle is big, the easily electrostatic attraction of adjacent PVC paste resin, and causes PVC paste resin
Particle diameter change is big, and mobility is deteriorated, and the technical problem of adhesion screen cloth and the became uneven adhered on mould occurs, causes manufactured
PVC gloves can not meet the standard of medical gloves,
The PVC paste resin provided by the invention for preparing medical gloves passes through VCM, composite initiator, breast
The coordinated of agent and dispersion stabilizer, reduce the surface of the obtained PVC paste resin particle for preparing medical gloves
Tension force, permeability is improved, so that manufactured PVC paste resin uniform particle diameter, good fluidity, is passing through infusion process
When carrying out medical gloves preparation, sieving is fast, and the sieving time is no more than 35 seconds, and the thin and thick uniformity adhered on mould is made
Into PVC gloves not only occur without broken hole, and there is good mechanical strength, the standard for reaching medical gloves requires.
In a preferred embodiment of the invention, composite initiator is by least one azo-initiator and at least one mistake
Oxide-based initiator is combined, and wherein azo-initiator is azodiisobutyronitrile or ABVN；Peroxide
Class initiator be di-cyclohexylperoxy di-carbonate, di-isopropyl peroxydicarbonate, dicetyl peroxydicarbonate hexichol oxygen ethyl ester,
Dicetyl peroxydicarbonate two (2- ethyoxyls) ethyl ester, new peroxide tert-butyl caprate or peroxidating are double (3,5,5- pivaloyl).
The composite initiator being combined by using azo-initiator and peroxide type initiators, can effectively it carry
The velocity of initiation of perchloroethylene monomer, accelerate polymerisation run, shorten polymerization cycle.
In a preferred embodiment of the invention, composite initiator both can be by a kind of azo-initiator and a kind of peroxide
Compound class initiator is combined, can also be by a kind of azo-initiator and two or more peroxide type initiators
It is combined, can also be combined by two kinds of azo-initiators with two or more peroxide type initiators.
In a preferred embodiment of the invention, emulsifying agent is at least one anion surfactant, the anion
Surfactant is hard soap, long chain alkyl sulfates, aromatic sulfonate, sldium lauryl sulfate, hexadecanol sulfuric acid
Sodium, sodium lauryl sulfate or neopelex.
By using anion surfactant as emulsifying agent so that vinyl chloride monomer dispersion is evenly, more stable,
So that the heat of polymerisation generation is more easy to spread, polymerisation is more stable more easy to control, the PVC paste resin generated
Molecular weight distribution it is narrower, particle diameter is evenly.
In a preferred embodiment of the invention, dispersion stabilizer is aerosol OT.
By using aerosol OT as dispersion stabilizer and the emulsification using anion surfactant
Agent mutually cooperates with so that the surface tension of obtained PVC paste resin particle reduces, and permeability improves, so that system
The uniform particle diameter of the PVC paste resin for preparing medical gloves obtained, good fluidity, sieving is fast, is adhered on mould uniformly,
So that obtained PVC paste resin meets the requirement of medical gloves.
According to another aspect of the present invention, the invention provides the above-mentioned PVC paste resin for preparing medical gloves
Production method, comprise the following steps：
(a) VCM, deionized water, composite initiator, emulsifying agent and dispersion stabilizer are well mixed, risen
Temperature polymerization；
(b) after unreacted VCM is reclaimed, polyvinylchloride latex is spray-dried and ground bag
Dress, that is, prepare the PVC paste resin of medical gloves.
The production method of the PVC paste resin provided by the invention for preparing medical gloves, technique is simple, easy to operate,
Obtained PVC paste resin uniform particle diameter, good fluidity, when carrying out medical gloves preparation by infusion process, sieving
It hurry up, the sieving time is no more than 35 seconds, the thin and thick uniformity adhered on mould, and made PVC gloves is not only without broken
Hole occurs, and has good mechanical strength, reaches the standard requirement of medical gloves.
The production method of the PVC paste resin provided by the invention for preparing medical gloves using microsuspending method prepare and
Into.
In step (a), by VCM, deionized water, composite initiator, emulsifying agent and dispersion stabilizer in strength
Stirring is lower well mixed so that vinyl chloride monomer dispersion suspends in water into countless small liquid pearls, in the effect of composite initiator
Lower trigger carries out polymerisation, emulsifying agent and dispersion stabilizer coordinated so that VCM liquid pearl stable dispersion, so as to
So that the PVC paste resin particle surface tension force of generation is small, permeability is high, good flowing properties.
In step (b), the VCM for not carrying out polymerisation is reclaimed, to reduce energy waste, ensured
Prepare the stability of the PVC paste resin of medical gloves.The polyvinylchloride latex for reclaiming Vinylidene Chloride monomer is sprayed
Dry and grinding is packed, in order to be stored.
In a preferred embodiment of the invention, in step (b), VCM is recovered as first carrying out from pushing back
Receive, then carry out pressure recovery.
The PVC paste resin provided by the invention for preparing medical gloves is that the polymerization that heats up is carried out in polymeric kettle, when
After pressure in polymeric kettle declines, polymerisation terminates, and 10% VCM is there is also about in polymeric kettle, and this just needs to carry out
Recycle.Because pressure is very big in polymeric kettle, start first carry out from receipts are pushed back, with the progress for pushing back receipts certainly, polymerization
Pressure in kettle constantly reduces, and the recovery speed of VCM is also slower and slower, in order to improve organic efficiency, can be forced
Recovery, until the VCM in polymeric kettle is recovered and finished.
In a preferred embodiment of the invention, in step (a), the temperature of polymerization is 40-50 DEG C.
When carrying out heating polymerization, if the temperature of polymerization is too high, although the speed of polymerization can be accelerated, easily occur
Implode phenomenon, cause the molecular weight of generated PVC paste resin excessive, distribution is wide, can not meet to use needs, if
Temperature is too low, then the reaction speed polymerizeing is excessively slow, causes the production cycle for producing vinyl chloride paste resin long, formation efficiency mistake
Low, production cost remains high.
Proved through test of many times, 40-50 DEG C is maintained the temperature at when heating up and polymerizeing, obtained PVC paste resin
Narrow molecular weight distribution, uniform particle diameter, it disclosure satisfy that requirement.
In a preferred embodiment of the invention, in step (a), heating polymerization is carried out under conditions of nitrogen charging.
It is polymerize by the heating that VCM is carried out under the conditions of nitrogen charging, avoids VCM during polymerization
By the dioxygen oxidation in air, the progress of polymerisation is influenceed.
