Description
Technical field
Patent of the present invention is related to a kind of preparation field of PVC, be especially to provide a kind of low VOC environment-friendly type PVCs gloves and its
Preparation method.
Background technology
With the promulgation of national items relevant policies regulation, the improvement of people's living standards and the awakening of environmental consciousness,
Limitation to environmental toxic discharge of poisonous waste is more and more stricter, and in PVC glove preparation field, (volatility is organic to prepare low VOC
Thing) environment-friendly type PVC gloves, can effectively reduce the pollution to environment, and the gloves security quality of special industry is improved, improve
People's living standard.
Conventional PVC glove is required for adding substantial amounts of plasticizer in the process for preparing, while gloves are carried out into high temperature baking
It is roasting, the process of gloves releasing organics can be undoubtedly accelerated during baking.When VOC exceedes finite concentration, in a short time
People can feel headache, Nausea and vomiting, limbs fatigue.If leaving scene not in time, can feel that above symptom is aggravated, seriously
When can twitch, go into a coma, cause failure of memory.Liver, kidney, brain and the nervous system that VOC understands harm people can even be led
Cause blood of human body to go wrong, cause other serious diseases such as leukaemia.Plasticizer is a species environmental estrogens, with life
Grow and development toxicity, or even the plasticizer having has oncogenic function.It is not the change of covalent bond between plasticizer and high molecular polymer
Combination is learned, only common physical bond, therefore over time, plasticizer can be slowly escaped through from gloves,
Contaminated air, soil, water source or even food, gradually accumulate in human body and resolve into corresponding metabolite, and then endanger people
Body health.
At present, conventional gloves are required for adding substantial amounts of plasticizer, but prior art on PVC in the process for preparing
Preparation process in, the concept of VOC is not the emphasis for considering, only considers result that plasticizer directly separates out from product to divide
Analyse and evade pollution sex chromosome mosaicisms of the PVC to environment, not from whole process route inquire into its it is profound the reason for, and provide solution
The measure of problem, therefore traditional preparation method and analytical mathematics can not thoroughly solve the pollution during PVC uses to environment.
Patent of the present invention is improved primarily directed to problem set forth above, so as to effectively improve and process gloves in use environment
In the volatile organic matter that discharges.Therefore develop a kind of PVC of low VOC, and be applied in gloves and turn at present the most
Urgent demand.
The content of the invention
The purpose of the present invention：In use, easily there is thermo-oxidative ageing primarily directed to PVC glove in patent of the present invention
Degraded, the problems such as separating out organic volatile VOC and cause environmental pollution, there is provided a kind of low VOC environment-friendly type PVCs gloves and its preparation
Method is solving the above problems.
Technical scheme：The present invention prepares low VOC environment-friendly type PVCs gloves using the plasticizer of low VOC content.
According to mass fraction, the formula of low VOC plasticizer is：
80~90 parts of polyester type plasticizer
0.5~1 part of antioxidant
1~5 part of inorganic adsorbent.
Preferably, polyester type plasticizer be W2500, UN-615, Ultramoll IV (4), W8000 or W-2050, its with
The compatibility of macromolecular material is good, and volatility is low, the extraction of oil resistant and resistance to aliphatic or aromatic hydrocarbons, resistance to migration
Property, resistance to ag(e)ing be excellent and high temperature resistant etc..
Preferably, antioxidant be 1010,168, BHT, 1076, CA, 164, DNP or MB, antioxidant is a class chemicals
Matter, in the presence of it is only a small amount of in polymeric system, so that it may delay or suppress the carrying out of polymer oxidizing process, so as to prevent
Polymer aging simultaneously extends its service life.Inorganic adsorbent is the zeolite powder or silica of 0.5-2 μm of particle diameter.
According to mass fraction, the formula of low VOC environment-friendly type PVCs gloves is：
Described stabilizer is the one kind in potassium zinc stabilizer, sodium zinc stabilizer, magnesium calcium zinc stabilizer.
Preferably, polyurethane is 5712,58144,54601,5715 or 58091, polyurethane is a kind of new organic
High molecular synthetic material, is a kind of excellent thermoplastic elastomer (TPE) of properties, and excellent in abrasion resistance, ozone resistance are fabulous, intensity
High, elasticity is good, low temperature resistant, with good oil resistant, chemicals-resistant, environmental resistance.
Preferably, dispersant be Solsperse 3000, Solsperse13650, Solsperse 22000 or
Solsperse 5000.Surfactant is the alcohol ether with fixed hydrophilic lipophilic group, alkanolamide, dodecyl sodium sulfonate
One kind or its mixture in sodium, NPE, ZWP, can be effectively improved the configuration of surface of PVC emulsions；It is inorganic
Adsorbent is the zeolite powder or silica of 0.5-2 μm of particle diameter.
The preparation method of low VOC plasticizer：
1. plasticizer, antioxidant, inorganic adsorbent are mixed according to low VOC plasticizer formulas, first normal temperature premix 10~
20min, rotating speed is 100r/min~150r/min；
2. 100 DEG C are warming up to, continue 10~20min of blending and stirring, rotating speed is 100r/min~150r/min, is cooled to often
Temperature discharging.
The preparation method of low VOC environment-friendly type PVCs gloves：
1. each component stirring is mixed into thickener by the formula of low VOC environment-friendly type PVCs gloves, is filtered, vacuumized, stood；
2. the material that 1. step is prepared is put into production line hopper, 170 DEG C of thickener is impregnated with 80 DEG C of glove models
After 100s, 5min shapings are toasted at a temperature of 230 DEG C, low VOC environment-friendly type PVCs gloves are obtained.
Preferably, the thickness of gloves is 20~50um.
Technique effect of the invention：Low VOC is primarily referred to as volatile organic content and specifies less than GB 18582-2008 standards
Limited Doses (≤120g/I).Easily occurs thermo-oxidative ageing degradation problem in use for PVC glove, the stabilization for using
Agent thermally decomposes the HCl for producing by catching PVC, prevents the catalytic degradation of HCl from acting on, and PVC is thermally decomposed the chlorination for producing
Hydrogen again with matrix dehydrochlorination and there is addition in the conjugated double bond that is formed, suppress the growth of conjugated chain, effectively prevent
The degraded of PVC.For the problem that organic volatile is separated out during gloves use, inorganic adsorbent is respectively added at twice
In low VOC plasticizer and low VOC environment-friendly type PVCs gloves, because inorganic adsorbent consumption is smaller, it is directly appended in PVC
Easily absorbed by other liquid adjuvants in process, while also easily being separated out from product in the case of non high temperature, it is impossible to
The function of VOC is adsorbed under performance high-temperature condition.It is blended and is fixed in plasticizer, is efficiently solved the problem.In PVC
Adsorbent adsorbs VOC in routine use, and high temperature produces VOC in use, while the adsorbent in plasticizer is also in height
VOC is discharged and adsorbed in the presence of temperature.The present invention prepare low VOC gloves effectively prevent to operated environment and some
The pollution of valuable instrument and equipment, so as to reduce it in use to the damage of human body, good characteristic is waited with environment-friendly.
