Description

Insulating PVC (polyvinyl chloride) glove and preparation method thereof
Technical Field
The invention relates to the technical field of gloves, in particular to an insulating PVC glove and a preparation method thereof.
Background
PVC has been the most widely used plastic in world, and is widely used in various fields such as building materials, floor leathers, pipes, packaging films, foaming materials and the like. Among them, the PVC gloves occupy most of market share due to the advantages of low allergy, low cost, corrosion resistance, good chemical stability and the like.
PVC belongs to polar high polymer, has natural insulating ability, is made into various insulating materials for use, such as insulating adhesive tapes, wires and cables, insulating electrical sleeves and the like, and the field of insulating PVC gloves is blank, so that the development of an insulating PVC glove has important significance.
Although the PVC material has natural insulating capability, the insulating property of the PVC material is influenced due to the introduction of various ions. The introduction route of the ions comprises ionic impurities brought in by the PVC resin during polymerization and processing; ionic impurities brought by compounding agents such as a plasticizer, a stabilizer and the like in the compounding process; chloride ions generated by thermal degradation in the plasticizing process, and the like.
Disclosure of Invention
The invention aims to provide an insulating PVC glove and a preparation method thereof. The glove overcomes the problem that the insulating property of the PVC material is reduced due to the introduction of various ions by adding the special insulating modifier, so that the insulating glove has excellent insulating property compared with the common glove. The insulating PVC glove is suitable for being worn and used by power system workers, simple in production process, low in cost and capable of filling the blank in the field of insulating PVC gloves through dipping and forming, and has strong market competitiveness.
The invention is realized by the following technical scheme:
an insulating PVC glove comprises the following components in parts by weight:
100 parts of PVC resin powder;
45-95 parts of a plasticizer;
1-1.5 parts of a stabilizer;
20-35 parts of a viscosity reducer;
8-15 parts of an insulation improver.
Preferably, the PVC resin powder is bulk polymerization PVC resin powder.
Preferably, the insulation improver is one or two of calcined pottery clay and insulation mica.
Further, the insulation improver comprises calcined argil and insulation mica in a mass ratio of 1: 1.
Preferably, the plasticizer is one or a mixture of trioctyl trimellitate, tricresyl phosphate and methyl pentachlorocyanate.
Further, the plasticizer is:
30-55 parts of trioctyl trimellitate;
10-30 parts of tricresyl phosphate;
5-15 parts of methyl pentachloro stearate.
As another object of the present invention, the above method for preparing an insulating PVC glove comprises the steps of:
(1) adding PVC resin powder, a plasticizer, a stabilizer, a viscosity reducer and an insulation improver into a stirring tank, stirring for 5 hours, preparing a paste material, wherein the viscosity of the paste material is 60-80mpa.s, and defoaming in vacuum for later use;
(2) preheating a hand mould to 60 ℃, soaking the paste, dripping for 1.5 minutes, and plasticizing in an oven at 190 +/-5 ℃ for 5.5 +/-0.5 minutes; after the hand mould is cooled to 70 ℃, soaking the polyurethane slurry, and drying the polyurethane slurry in an oven at the temperature of 130 +/-10 ℃ for 2 minutes;
(3) after cooling, the finished product is obtained by crimping and demoulding.
Preferably, the preparation method of the insulating PVC glove comprises the following steps: the method comprises the following steps:
(1) adding PVC (polyvinyl chloride), trioctyl trimellitate, tricresyl phosphate, methyl pentachlorocyanate, a stabilizer, a viscosity reducer and an insulation improver into a stirring tank, stirring for 5 hours, preparing a paste material, wherein the viscosity of the paste material is 60-80mpa.s, and defoaming in vacuum for later use;
(2) preheating the hand mould to 60 ℃, dipping the paste, dripping for 1.5 minutes, and plasticizing in an oven at 190 +/-5 ℃ for 5.5 +/-0.5 minutes. After the hand mould is cooled to 70 ℃, soaking the polyurethane slurry, and drying the polyurethane slurry in an oven at the temperature of 130 +/-10 ℃ for 2 minutes;
(3) after cooling, the finished product is obtained by crimping and demoulding.
The main characteristic of the bulk polymerization production process is that no water and dispersant are needed in the reaction process. The polymerization is carried out in 2 steps, step 1, certain amount of VCM monomer, initiator and additive are added in a prepolymerization kettle, and prepolymerization is carried out in the kettle under the action of strong stirring (relative to the polymerization process in step 2) after heating. When the conversion rate of VCM reaches 8% -12%, stopping reaction, and feeding the generated seeds into a polymerization kettle to make the 2 nd step reaction. After the polymerizing kettle receives the prepolymerized 'seeds', a certain amount of VCM monomer, additive and initiator are added, polymerization is continued on the basis of the 'seeds', the 'seeds' grow up to a certain degree gradually, and polymerization reaction is carried out under the action of low-speed stirring and constant pressure. When the conversion rate of reaction reaches 60-85% (depending on the formula), the reaction is terminated, and degassing is carried out in a polymerization kettle, unreacted monomers are recovered, then stripping is carried out in the kettle, VCM remained in PVC powder is further removed, and finally the PVC powder in the kettle is sent to the working procedures of grading, homogenizing and packaging through an air conveying system.
The mass polymerization method can carry out polymerization under the conditions of no water, no dispersant and no emulsifier, only adding an initiator, and no surfactants such as emulsifier, dispersant and the like need to be added, so that the resin powder is prevented from being attached with a small amount of emulsifier and dispersant residues, and the insulating property of the PVC product is not influenced.
The insulation improver is one or two of calcined argil or insulation mica. Mica is a silicate mineral rich in metals such as potassium, aluminum, magnesium, iron, and lithium, and these metal elements exist in valence bond form, have good insulating properties, and are widely used in the electronics and power industries. The PVC material has an influence on the insulating property of the PVC material due to ionic impurities brought by PVC resin in the polymerization and processing processes and various accessory ingredients. The argil is hydrated aluminum silicate, crystal water is removed in the calcining process, a plurality of cavities are formed in the dehydration part, and the cavities are active adsorption centers and are easy to adsorb ion impurities, so that the concentration of free ions in the PVC gloves is reduced, and the insulating property of the PVC gloves is obviously improved.
According to the insulating PVC gloves, the plasticizer with good insulating property is selected in the formula, the volume resistivity of pure PVC resin and PVC hard products is very high, and the resistivity can be reduced by adding the plasticizer. In particular, the PVC soft product has high plasticizer adding amount, so the selection of the plasticizer has great influence on the product insulation. Generally, a plasticizer having low polarity tends to lower the resistivity, and a plasticizer having high polarity has good insulating properties. The plasticizer such as trioctyl trimellitate, tricresyl phosphate, methyl pentachloro stearate, chlorinated paraffin and the like has excellent insulating property.
The beneficial effect of this application is: compared with the disposable PVC gloves in the prior art, the insulating gloves have excellent insulating property. The insulating PVC glove is suitable for being worn and used by power system workers, simple in production process, low in cost and capable of filling the blank in the field of insulating PVC gloves through dipping and forming, and has strong market competitiveness.
