Problems solved by technology

[0004] The traditional PVC glove production industry is a high energy consumption and high pollution industry. In the production process, saturated alkanes are used as diluent solvents, which not only increases the production cost but also causes environmental pollution. At the same time, the processing temperature of ordinary PVC gloves needs to be 150-220 °C, which consumes a lot of energy. The traditional PVC glove production industry is bound to be greatly impacted under the policy of carbon peak and carbon neutrality

preparation example Construction

[0030] The invention provides a kind of preparation method of plastic gloves, comprises the following steps:

[0031] A) Stir and mix plasticizer, stabilizer, emulsifier, water and PVC copolymerization modified emulsion to obtain mixed slurry; said plasticizer includes phthalates, terephthalates, citric acid At least one of esters, adipates and epoxy fatty acid esters;

[0032] B) vacuum defoaming the mixed slurry to obtain the mixed slurry after vacuum defoaming;

[0033] C) Dip the hand mold in the coagulant solution, take it out and dry it, then immerse it in the mixed slurry after vacuum degassing, take it out and dry it, bake it to plasticize, and obtain a plastic glove.

[0034] The present invention first stirs and mixes the plasticizer, stabilizer, emulsifier, water and PVC copolymerization modified emulsion to obtain the mixed slurry; the plasticizer includes phthalates, terephthalates, lemon At least one of acid esters, adipate esters and epoxy fatty acid esters. ...

Abstract

The invention provides a preparation method of a plastic glove, which comprises the following steps: A) stirring and mixing a plasticizer, a stabilizer, an emulsifier, water and a PVC (Polyvinyl Chloride) copolymerized modified emulsion to obtain mixed slurry, wherein the plasticizer comprises at least one of phthalic acid esters, terephthalic acid esters, citric acid esters, adipic acid esters and epoxy fatty acid esters; B) performing vacuum defoaming on the mixed slurry to obtain mixed slurry subjected to vacuum defoaming; and C) dipping a hand mold in a coagulator solution, taking out and drying the hand mold, dipping the hand mold in the vacuum-defoamed mixed slurry, taking out and drying the hand mold, and conducting baking and plasticizing to obtain the plastic glove. The use of a diluting solvent and a viscosity reducer is avoided, the cost of the glove is reduced, the processing temperature is low, VOC emission is avoided in the glove production process, the glove is green and environmentally friendly, and the prepared plastic glove is low in plasticizer content, low in glove plasticizer precipitation value, small in thickness, uniform in thickness distribution and excellent in mechanical property.

Description

technical field [0001] The invention relates to the technical field of plastic glove production, in particular to a plastic glove and a preparation method thereof. Background technique [0002] Disposable health protective gloves are widely used in many industries including electronics, chemical industry, aquatic industry, hospital, scientific research, food processing and other industries. At the same time, due to factors such as health and hygiene, product quality control, and employee safety, the demand for disposable health protective gloves is expected to continue to grow. It is predicted that the global scale of disposable protective gloves will increase from US$7.630 billion in 2014 to US$17.242 billion in 2022, with an average annual compound growth rate of 12.6%. [0003] The material of gloves can be divided into disposable PVC gloves, nitrile gloves and latex gloves. The raw material of PVC gloves is PVC powder, the price is relatively low, and the application r...
