Embodiment 1

[0025] Concrete raw material is weighed by table 1, and step preparation step is as follows:

[0026] (1) PVC resin, tricresyl phosphate, trioctyl trimellitate, dioctyl adipate, liquid calcium zinc stabilizer, calcium sulfate whiskers, basic magnesium sulfate whiskers are added in the mixer, at temperature Under the conditions of 60°C and a rotating speed of 800r / min, after stirring for 4 hours, let it stand for defoaming to obtain a mixture;

[0027] (2) adding calcium stearate, glyceryl stearate, and chlorinated polyethylene into the mixture prepared in step (1), stirring for 40 min at a temperature of 60° C. and a rotating speed of 800 r / min, Prepare an impregnation solution;

[0028] (3) After preheating the hand mold to 70°C, put the hand mold into the dipping solution prepared in step (2), put the dipped hand mold into an oven, and heat the hand mold at a temperature of 220°C Bake for 10 minutes and serve.

Embodiment 2

[0030] (1) PVC resin, tricresyl phosphate, trioctyl trimellitate, dioctyl adipate, liquid calcium zinc stabilizer, calcium sulfate whiskers, basic magnesium sulfate whiskers are added in the mixer, at temperature Under the conditions of 70°C and a rotating speed of 1000r / min, after stirring for 2 hours, let it stand for defoaming to prepare the mixture;

[0031] (2) adding calcium stearate, glyceryl stearate, and chlorinated polyethylene into the mixture prepared in step (1), stirring for 20min at a temperature of 70°C and a rotating speed of 1000r / min, Prepare an impregnation solution;

[0032] (3) After preheating the hand mold to 80°C, put the hand mold into the dipping solution prepared in step (2), put the dipped hand mold into an oven, and carry out the process at a temperature of 240°C Bake for 5 minutes and serve.

Embodiment 3

[0034] (1) PVC resin, tricresyl phosphate, trioctyl trimellitate, dioctyl adipate, liquid calcium zinc stabilizer, calcium sulfate whiskers, basic magnesium sulfate whiskers are added in the mixer, at temperature Under the conditions of 70°C and a rotating speed of 1000r / min, after stirring for 3 hours, let it stand for defoaming to prepare the mixture;

[0035] (2) adding calcium stearate, glyceryl stearate, and chlorinated polyethylene into the mixture prepared in step (1), stirring for 30min at a temperature of 70°C and a rotating speed of 1000r / min, Prepare an impregnation solution;

[0036] (3) After preheating the hand mold to 80°C, put the hand mold into the dipping solution prepared in step (2), put the dipped hand mold into an oven, and carry out the process at a temperature of 240°C Bake for 10 minutes and serve.

Abstract

The invention relates to the technical field of materials, in particular to a high-strength low-temperature-resistant PVC glove and a preparation method thereof. The PVC glove is composed of PVC resin, chlorinated polyethylene, a plasticizer, a stabilizer, a viscosity reducer and a low-temperature-resistant additive. The PVC glove provided by the invention has a relatively low glass transition temperature, can resist a low temperature below zero, and is suitable for being used in a low-temperature environment; meanwhile, the PVC glove provided by the invention also keeps relatively high strength and relatively good elasticity, so that a wearer feels more comfortable.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a high-strength low-temperature resistant PVC glove and a preparation method thereof. Background technique [0002] PVC used to be the most widely used general-purpose plastic in the world, widely used in various aspects such as building materials, floor leather, pipes, packaging films, and foaming materials. Among them, PVC gloves occupy most of the market share due to its advantages such as non-allergic, low cost, corrosion resistance, and good chemical stability. [0003] PVC is a white powder with an amorphous structure, the degree of branching is small, and the glass transition temperature is 77-90 ° C. The resin molecules are combined by a strong van der Waals force. The rigidity is strong and the flexibility is insufficient, which causes PVC resin processing. more difficult. In order to solve these problems, it is necessary to introduce plasticizers in the process of P...
