Embodiment 1

[0022] 1. Use PVC paste resin as raw material and acetylated tributyl citrate (ATBC) as plasticizer. The formula ratio is shown in Table 1.

[0023] Table 1 Preparation ratio of slurry (ATBC is plasticizer)

[0024] raw material name Proportion / % Actual dosage / g PVC paste resin 100 4600 ATBC 80 3680 Calcium zinc stabilizer 0.75 34.5 Viscosity reducer (D25 dearomatization solvent) 25 1150

[0025] 2. Prepare the slurry according to the above ratio and stir for 2 hours;

[0026] 3. Check the viscosity of the slurry;

[0027] Table 2 Viscosity test of slurry

[0028] temperature / ℃ 35 40 45 50 55 57 60 65 70 75 Viscosity mPa·s 89 71 63 57 54 58 61 79 105 149

[0029] It can be seen from Table 2 that the optimal temperature of the slurry (the temperature of the slurry in the slurry tank) is between 55 and 57°C, and when the temperature exceeds 60°C, its viscosity rises sharply. It can be seen th...

[0035] Compound Plasticizer of ATBC and Epoxy Fatty Acid Methyl Ester

[0036] 1. Prepare the slurry according to the following ratio;

[0037] Table 4 The preparation ratio of slurry (ATBC and epoxy fatty acid methyl ester compound plasticizer)

[0038] raw material name Proportion / % Actual dosage / KG PVC paste resin 100 4600 ATBC 70 3220 epoxy fatty acid methyl ester 10 460 Calcium zinc stabilizer 0.75 34.5 Viscosity reducer 25 1150

[0039] 2. Stir the prepared slurry for 2 hours, and treat it with vacuum -0.29MPa. There are a lot of small bubbles on the surface of the slurry after standing still. After vacuum defoaming, put it in an oven and heat it to 52°C;

[0040] 3. After heating the tiles to 60°C, soak them in the slurry, take them out and drop them for 1 minute, then put them into ovens with temperatures of 190°C, 195°C, 200°C, 205°C, and 210°C±3°C for 10 minutes. , making the PVC mature into such figure 1 film s...

[0044] Dioctyl terephthalate / trioctyl trimellitate compounded as plasticizer

[0045] 1. Prepare the slurry according to the following ratio;

[0046] Table 5 Preparation ratio of slurry (dioctyl terephthalate plasticizer)

[0047] raw material name Proportion / % Actual dosage / KG PVC paste resin 100 4000 Dioctyl Terephthalate / Trioctyl Trimellitate 80(40 / 40) 3200(1600 / 1600) Calcium zinc stabilizer 0.75 30 Viscosity reducer 32 1280

[0048] 2. Prepare the slurry according to the above ratio and stir for 2 hours;

[0049] 3. Test the viscosity of the slurry at different temperatures;

Abstract

The invention relates to a preparation method of an environmentally-friendly disposable polyvinyl chloride (PVC) glove, belonging to the fields of synthesis, application and processing shaping of high polymer materials. PVC paste resin is used as a raw material, a non-phthalic acid ester plasticizer, a non-heavy metal heat stabilizer and the like are used as the additives of an environmentally-friendly formula, and a calcium/zinc composite is used as the heat stabilizer to prepare the environmentally-friendly disposable PVC medical or civilian glove, wherein the plasticizer can be triisooctyl trimellitate (TOTM), dioctyl terephthalate (DOTP), biological oil-based ester, vegetable oil-based ester, fatty acid triglyceride, epoxy fatty acid ester or citrate ternary ester compounds. The invention provides the method for preparing the non-toxic and environmentally-friendly disposable PVC glove; and the prepared glove successfully passes the international SGS detection and the main properties of the product are obviously better than those of the similar PVC products in the market.

Description

technical field [0001] The invention mainly relates to a preparation method of a novel environment-friendly PVC disposable glove, which belongs to the field of synthesis, application and processing of new polymer materials. Background technique [0002] Disposable PVC gloves have stable performance, good protection, comfortable wearing, wide application fields and low price. They have better development prospects than disposable latex gloves, nitrile gloves and PE gloves. Although disposable PE gloves are cheap, they are not elastic enough and are easily damaged; although disposable latex gloves currently occupy a large market share, they are expensive and cause skin allergies, and the market demand is gradually declining; disposable PVC gloves are resistant to acids and alkalis , Anti-chemical corrosion, anti-static, good protection effect, comfortable to wear. A comprehensive comparison shows that disposable PVC gloves have good cost performance and have good development ...
