Embodiment 1～4、 comparative example 1～3

[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] Note: " / " in Table 1 means no such component; "initial viscosity" refers to the viscosity when no viscosity reducer TXIB is introduced in Examples 1-4, and no solvent D70 is introduced in Comparative Examples 1-3.

[0039] The preparation method is as follows:

[0040] Add plasticizer and viscosity reducer (or solvent) into the batching kettle equipped with mixing and cooling system, add PVC paste resin powder during low-speed stirring, start fast stirring after feeding, after stirring for 4 hours, add stabilizer , continue to stir for 1 hour, the temperature during the stirring process is not higher than 55 ° C, to obtain a slurry;

[0041] After the stirring is completed, transfer the slurry to a static tank for 24 hours; after that, vacuum defoaming at -0.09MPa~-0.1MP...

Abstract

The invention provides PVC (polyvinyl chloride)-based composition, PVC gloves and a preparation method of the PVC gloves. The provided PVC-based composition is prepared from PVC paste resin, a plasticizer, a stabilizer and a viscosity reducer, wherein the plasticizer is prepared from acetyl tributyl citrate and epoxidized soybean oil; the viscosity reducer is 2,2,4-trimethyl-1,3-pentanediol-diisobutyrate. Compared with conventional PVC gloves, the PVC gloves are prepared with a specific formula, VOC (volatile organic compound) emission can be greatly reduced, the atmospheric contamination is reduced, the PVC gloves are safer and more environmentally friendly and do not harm human bodies, and besides, equivalent mechanical performance can be guaranteed. The provided preparation method is simple and easy to implement, mild in condition, easy to operate, environmentally friendly and favorable for large-scale production and meets the environmental protection and green development concept.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PVC-based composition, 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. Traditional PVC protective gloves usually contain DINP / DOP plasticizers. On December 13, 2013, the California Office of Environmental Health Hazard Assessment (OEHHA) included diisononyl phthalate (DINP) in the California Proposition 65 "1986 The list of carcinogens in the Drinking Water Safety and Toxic Enforcement Act, which came into effect on December 20, 2013. According to the relevant requirements of California 65, all products containing DINP sold in California need to have warning signs, and many products facing exit from the market....
