Problems solved by technology

The result is reduced production efficiency, resulting in waste of finishing agents and additional consumption of labor
Due to the extremely thin coating, the moisture and electrolytes in sweat seep out after wearing gloves, which will easily damage and fall off the coating, thus making the wearability worse, and the peeled off coating may cause contamination of wounds or testing equipment
In addition, there are still a small number of people whose skin is allergic to gloves prepared with such finishes
[0005] Therefore, the powder-free PVC gloves prepared now still have the problems of low productivity, coating shedding may cause pollution and skin allergies may occur. It is necessary to develop a new preparation method of powder-free PVC gloves and the used finishing agent

Embodiment 1

[0034] Add 800 parts by mass of deionized water into a reactor with a condensation reflux device, add 6 parts by mass of polymer suspending agent polyvinyl alcohol, add 1 part by mass of sodium polyacrylate as a dispersant, and add 2 parts by mass of magnesium hydroxide , stir to disperse evenly. 5 parts by mass of methyl acrylate, 40 parts by mass of methyl methacrylate, 50 parts by mass of styrene, 5 parts by mass of bisacryloyl-terminated polydimethylsiloxane and 0.5 parts by mass of dibenzoyl peroxide were pre-mixed uniform, and added to the above aqueous medium. Under strong stirring, polymerize at 80-90°C for 6 hours, then raise the temperature to 100°C and keep it warm for 5 hours to fully react the monomers. After polymerization, cool to room temperature, filter, pickle to remove inorganic salts, then wash with water and air-dry, and finally sieve and classify. Polysiloxane-modified styrene-acrylic resin microparticles with a particle diameter of 2 μm to 10 μm are ob...

Abstract

The invention discloses a functional PVC plastisol used by powderless PVC gloves and the application of the plastisol, belonging to the technical field of the PVC gloves; to solve the problems of low production efficiency and bad dressing effect of present powderless PVC gloves, the functional PVC plastisol is made from benzene inner resin particles which are modified by PVC emulsification powder, primary plasticizers, secondary plasticizers, viscosity depressants, stabilizing agents and polysiloxane, uniformly mixed and treated with vacuum defoamation; a preheated hand die is gelled to form a film after going through digestion and roast in the ordinary PVC plastisol, then is gelled to form a film by digestion and roast in the functional PVC plastisol of the invention and then the powderless gloves with good dressing effect and no self conglutination are obtained by edge turning and parting.

Description

technical field [0001] The present invention relates to a kind of PVC plastisol and its application, more specifically, the present invention relates to a kind of functional PVC plastisol for preparing powder-free PVC gloves and the method for using it to prepare non-adhesion gloves. Background technique [0002] Disposable film PVC gloves are made by dipping the glove mold into PVC plastisol solution and baking at about 210°C to form a gel into a film. When untreated, due to the self-adhesiveness of the PVC material used to prepare the gloves, it is difficult to release the gloves during production, and the inner surface of the gloves will be seriously stuck after offline, making it inconvenient to wear during use. For this reason, it is necessary to treat the surface of the glove first, and then turn over the treated glove so that the original outer surface becomes the inner surface, so as to solve the above problems. [0003] Traditional powder-free PVC gloves are dip-co...
