Background technology
A kind of cheap versatility thermoplastic of polrvinyl chloride (PVC), have fire-retardant, wear-resisting, intensity is high, easy-formation processing and good chemical stability, be widely used in disposable elastic glove.But tradition PVC glove smooth surface, comparatively tight with the stickiness of hands, worn for long periods can cause hand perspiration to volatilize, perspiration infiltration interleaving agent, makes interleaving agent come off, causes skin uncomfortable or allergy.In order to solve breathability problem between disposable PVC glove and hands, traditional method i.e. laminating breathable fabric liner in obstruct glove, this not only needs to increase the technological process that PVC glove produces, cause that production cost increases, and the thickness of PVC glove increases, have impact on the touch sense of hands, how solving Problems existing becomes the focus of research.
Summary of the invention
Present invention aim to address that problems of the prior art are with not enough, there is provided a kind of point contact type ventilative PVC glove, its thinking is to be formed at PVC glove inwall to be beneficial to the projecting point increasing air flow property, thus solving worn for long periods perspiration problem, improve the breathability of PVC glove wearing and the comfortableness of wearing.
The preparation method that the present invention also provides for these glove, on existing PVC glove production line, can produce the glove of the road present invention by adjustment PVC composition and adjustment PVC glove manufacturing parameter, simple and convenient.
The present invention is achieved by the following technical solutions:
The contact of the present invention is breathed freely PVC glove, and it is made up of the raw material of following quality proportioning:
First after crosslinking elastic resin granule and part plasticizer mix and blend, pretreatment is carried out so that crosslinking elastic resin granule fully absorbs plasticizer, it is thus achieved that the elastic swellable resins of crosslinking is stuck with paste when preparing glove；Again polyvinyl chloride resin, heat stabilizer, antioxidant are put into stirring in residue plasticizer, add viscosity modifier, obtain low viscosity polyvinyl chloride resin and stick with paste；Again elastic for crosslinking swellable resins granule is put into low viscosity polyvinyl chloride resin to stick with paste, make the crosslinking elastic resin Granular composite fully absorbing plasticizer in low viscosity polyvinyl chloride resin is stuck with paste, after adopting ceramic hand-mold leaching thickener, put into syllogic temperature control streamline baking oven and toast and prepare the ventilative PVC glove of point contact type.
The ventilative PVC glove of point contact type that the present invention is above-mentioned, the crosslinking elastic resin granule that its further technical scheme is described is crosslinked PVC, crosslinking acrylonitrile butadiene, crosslinked polyurethane elastomer body, crosslinking neoprene, crosslinking butadiene-styrene rubber or crosslinkable chlorinated polyethylene.The degree of cross linking of crosslinking elastic resin is 40～60%, the chlorinty of crosslinkable chlorinated polyethylene is mass fraction 30～40%, the acrylonitrile content of crosslinking acrylonitrile butadiene is mass fraction 20～40%, the particle diameter of crosslinking elastic resin granule is 0.1mm～0.5mm, fully absorbs the crosslinking elastic resin grain diameter after plasticizer and is swelling to 1mm～5mm..
The ventilative PVC glove of point contact type that the present invention is above-mentioned, its further technical scheme can also is that described plasticizer be DOTP, 2,2,4-trimethyl-1, the double; two isobutyrate of 3-pentanediol, di-n-octyl sebacate, dioctyl adipate, tributyl 2-acetylcitrate, epoxy soybean oil or low molecular weight polyester.
The ventilative PVC glove of point contact type that the present invention is above-mentioned, its further technical scheme can also is that described viscosity modifier is kerosene, refining white oil, mixed benzene, aromatic solvent naphtha, aliphatic solvent oil or organic ketone solvent；Described heat stabilizer is calcium stearate, zinc stearate or barium stearate；Described antioxidant is phosphorous acid kind antioxidant is tricresyl phosphite (2, 4-di-tert-butyl-phenyl) ester, double, two (2, 4-di-tert-butyl-phenyl) pentaerythritol diphosphites, four [3-(3, 5-di-t-butyl-4-hydroxyphenyl) propanoic acid] quaternary amyl alcohol ester, 2, 2'-methylene-bis-(4-methyl-6-tert-butylphenol), β-(4-hydroxy phenyl-3, 5-di-t-butyl) the positive octadecanol ester of propanoic acid, 2, 6-di-tert-butyl-4-methy phenol, 4, 4'-thiobis (the 6-tert-butyl group-3-methylphenol), 4, 4 '-thiobis (6-tert-butyl-m-cresol), tetramethylolmethane four (3-lauryl thiopropionate) or β, β '-distearyl thiodipropionate.
The ventilative PVC glove of point contact type that the present invention is above-mentioned, its further technical scheme can also is that the viscosity that described low viscosity polyvinyl chloride resin is stuck with paste is 200～500mPa s.
The preparation method of the ventilative PVC glove of point contact type that the present invention is above-mentioned, it comprises the following steps:
1) carrying out pretreatment in the baking oven of 40 DEG C～70 DEG C after crosslinking elastic resin granule and plasticizer mix and blend, the time is not less than 48h so that crosslinking elastic resin granule fully absorbs plasticizer, it is thus achieved that the elastic swellable resins of crosslinking is stuck with paste；
2) polyvinyl chloride resin, heat stabilizer and antioxidant are put in residue plasticizer stirring 1h or more than, add viscosity modifier, stirring 30min or more than, finally put into the elastic swellable resins of crosslinking and stick with paste, stirring 10min or sizing material derived above；
3) sizing material prepared is put into vacuum defoamation machine carries out deaeration, Stress control at-0.095～-0.098MPa, continue deaeration 1h or more than, rear when standing 24h or thickener derived above；
4) after adopting dedicated ceramic fingerprint leaching thickener, initially enter Infrared Heating section to preheat, toast subsequently into baking oven, one district's temperature of described baking oven is 10 ± 5 DEG C higher than viscosity modifier boiling temperature, two district's temperature are 20 ± 5 DEG C higher than viscosity modifier boiling temperature, three district's temperature be higher than viscosity modifier boiling temperature 30 ± 10 DEG C, total baking time is 8～15min, baking volatilization solvent/plasticizer cooking fume reclaimed by negative pressure-pumping；
5), after having toasted, take off from fingerprint and obtain the ventilative PVC glove of point contact type.
Principles of the invention is as follows:
The crosslinking elasticity swellable particles fully absorbing plasticizer is dispersed in low viscosity polyvinyl chloride resin paste, after adopting ceramic hand-mold leaching thickener, viscosity is made to adjust solvent volatilization by toasting, owing to cross-linking the particle diameter of elastic swellable particles much larger than PVC glove thickness, so that the fingerprint outer surface of dipping PVC is dispersed with projecting point (after the demoulding, this outer surface becomes the inwall of PVC glove).The projecting point of PVC glove inwall, is conducive to forming air flowing between hands and glove, improves breathability and comfortableness that PVC glove is dressed.
The present invention compared with prior art has the advantages that
1, the present invention is beneficial to the projecting point of air flowing at PVC glove inner wall structure, improves the breathability of PVC glove wearing and the comfortableness of wearing；2, point contact type structure, the touch sense impact of opponent is less；3, the present invention is based on tradition PVC glove production line, only just can realize producing by adjustment PVC composition and manufacturing parameter；4, linear PVC strand enters in the elastic swellable resins granule of crosslinking, improves the adhesion strength between PVC and crosslinking elastic resin granule.
