Abstract

The invention discloses a preparation method of elastic disposable PVC (polyvinyl chloride) gloves. Each PVC glove comprises the following raw materials in parts by weight: 100 parts of PVC paste resin, 20-22 parts of dipropylene glycol dibenzoate, 26-28 parts of dioctyl terephthalate, 18-22 parts of fatty acid triglyceride, 1-2 parts of phosphate, 1.5-2.5 parts of acrylate, 0.5-1.5 parts of dihydric alcohol, 0.9-1.3 parts of a calcium-zinc complex heat stabilizer and 17-19 parts of a viscosity reducer. The preparation method comprises the following steps: (1) preparing the raw materials; (2) defoaming in vacuum; (3) preparing the glove by soaking a hand model in defoamed paste and baking, wherein the online temperature of the hand model before demoulding is 90-92 DEG C, the online temperature of the hand model before the soaking of the paste is 90-92 DEG C, the online temperature of the hand model before the soaking of wet powder is 135-137 DEG C, and the online temperature of a wet powder tank is 60-62 DEG C.

Description

technical field [0001] The invention relates to the technical field of safety protection, in particular to a preparation method of elastic disposable PVC gloves. Background technique [0002] 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 prospects. [0003] In order to increase the softness and plasticity of PVC gloves, plasticizers need to be added to the PVC paste resin. At present, the plasticizers in the formulation of PVC products mainly use phthalates as plasticizers, such as di(2-ethyl)hexyl phthalate (DOP), d...
