Problems solved by technology
[0003] At present, commonly used household PVC gloves are mainly solid gloves, and the wall thickness is about 0.01-0.02 mm. On the one hand, the material is relatively hard and the flexibility is poor, and the hands are prone to fatigue after wearing for a long time. On the other hand, the effect of heat insulation and cooling is limited. Affects the wearing experience during low (high) temperature operations

Embodiment 1～3、 comparative example 1
[0035] 1.1 Prepare PVC gloves according to the formula shown in Table 1:
[0036] Table 1 The formula of the embodiment of the present invention and comparative example PVC glove product
[0037]
[0038] The preparation method is as follows:
[0039] Put PVC paste resin, plasticizer, viscosity reducer, stabilizer and foaming agent in a container, and stir at high speed to form a uniform and stable liquid slurry; the temperature during the stirring process should not be higher than 55°C;
[0040] The resulting slurry is put into the production line for production, specifically:
[0041] The hand mold is dipped in the obtained slurry, and the slurry is attached to the hand mold; the hand mold impregnated with the slurry is put into a hot oil tube type closed oven for chain cycle baking, and the baking conditions are shown in Table 1;
[0042] After the baking is completed, the baking gloves are dipped in a slippery agent, which is a dilution of water-based polyurethane, wh...

Abstract
The invention provides a PVC (Polyvinyl Chloride)-based composition, a foamed PVC glove and a preparation method thereof. The PVC-based composition provided by the invention is prepared from a PVC paste resin, a plasticizer, a viscosity reducer, a stabilizer and a foaming agent, wherein the foaming agent comprises an ADC foaming agent. The PVC-based composition provided by the invention can be foamed during a glove processing process so as to form uniform and densely distributed micro bubbles, so that the glove is thicker under the same weight, the hardness cannot be increased, the softness ofthe glove is also improved, and the wear comfort is improved; meanwhile, with the production of uniform bubble layers and the increase of the glove wall thickness, heat-insulation and anti-cold performances of the glove are improved, and the glove can be worn and used at low (high) temperature.
Description
technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PVC-based composition, foamed PVC gloves and a preparation method thereof. Background technique [0002] PVC protective gloves are very commonly used protective products in industries such as housework, electronics, chemicals, aquaculture, glass, food, hospitals, and scientific research, including disposable gloves and household gloves. Among them, household PVC gloves have the characteristics of low cost, no need for cleaning and disinfection, and convenient use. They are widely used in industries such as sanitation cleaning, clothing cleaning, and food processing. Contact deals with damage to the subject's hand. [0003] At present, commonly used household PVC gloves are mainly solid gloves, and the thickness of the sleeve wall is about 0.01-0.02 mm. On the one hand, the material is relatively hard and the flexibility is poor, and the hands are prone to fatigue aft...
