Problems solved by technology

[0002] At present, the plasticizers used in disposable PVC gloves are mainly phthalates, English name: Phthalates, also known as phthalates, phthalates or phthalates, such as dioctyl phthalate ( DOP) and diisononyl phthalate (DINP), but phthalates have certain toxicity and are potentially carcinogenic
However, existing non-phthalate plasticizers, such as acetyl tributyl citrate (ATBC), are more costly than phthalates, and non-phthalate plasticizers are not as effective as phthalates

Embodiment 1

[0015] Dipropylene glycol dibenzoate 300g, epoxidized soybean oil 100g, diethylene glycol dibenzoate 200g, higher fatty alcohol benzoate 200g and calcium zinc stabilizer 15g are added in the stirring tank, Then add 1000g of PVC powder and stir for about 1.5 hours. Put the pasty raw material liquid after the first stirring into the storage tank and let it stand for about 30 hours. Then pour the raw materials back into the mixing tank again, and stir for about 1.5 hours to obtain the pasty raw materials;

[0016] Add 200g of viscosity reducer D80 to the pasty raw material to obtain a paste with adjusted viscosity;

[0017] The paste with adjusted viscosity was put into a vacuum tank for degassing for 8 hours to obtain the degassed paste.

[0018] Subsequently, the degassed paste was impregnated by a hand mold and put into an oven for baking and molding, and the baking temperature was 200°C. After baking, coat the PU coating on the glove, and after baking again, take the glove...

Embodiment 2

[0020] Dipropylene glycol dibenzoate 350g, epoxidized soybean oil 150g, diethylene glycol dibenzoate 300g, higher fatty alcohol benzoate 80g and calcium zinc stabilizer 30g are added in the stirring tank, Then add 1000g of PVC powder and stir for about 3 hours. Put the pasty raw material liquid after the first stirring into the storage tank and let it stand for about 60 hours. Then pour the raw materials back into the mixing tank, and stir for about 1 hour to obtain the pasty raw materials;

[0021] Add 350g viscosity reducer D80 in the raw material of described paste, obtain the paste that adjusts viscosity;

[0022] The paste with adjusted viscosity was put into a vacuum tank for degassing for 11 hours to obtain the degassed paste.

[0023] Subsequently, the degassed paste was impregnated with a hand mold and put into an oven for baking and molding at a baking temperature of 230°C. After baking, the modified starch is added to the glove, and then it is removed from the ha...

Embodiment 3

[0025] Dipropylene glycol dibenzoate 300g, epoxidized soybean oil 120g, diethylene glycol dibenzoate 300g, higher fatty alcohol benzoate 150g and calcium zinc stabilizer 20g are added in the stirring tank, Then add 1000g of PVC powder and stir for about 2.5 hours. Put the pasty raw material liquid after the first stirring into the storage tank and let it stand for about 48 hours. Then pour the raw materials back into the mixing tank again, and stir for about 1.5 hours to obtain the pasty raw materials;

[0026] Add 300g viscosity reducer D80 in the raw material of described paste, obtain the paste that adjusts viscosity;

[0027] The paste with adjusted viscosity was put into a vacuum tank for degassing for 10 hours to obtain the degassed paste.

[0028] Subsequently, the degassed paste was impregnated with a hand mold and put into an oven for baking and molding at a baking temperature of 220°C. After baking, coat the PU coating on the glove, and after baking again, take th...

Abstract

The invention provides a PVC glove production method by using a non-o-benzene plasticizer. The method is mainly used on the improvement of the materials that are used. The materials that are used are as follows: 100 portions of PVC powder, 20 to 40 portions of dipropylene glycol dibenzoate, 10 to 15 portions of epoxidized soybean oil, 10 to 35 portions of diethylene glycol dibenzoate, 5 to 20 portions of C8-C12 higher fatty alcohol benzoic ether, 1.5 to 3 portions of calcium-zinc stabilizer as well as 20 to 35 portions of viscosity reducer. The PVC gloves produced by the PVC glove production method by using a non-o-benzene plasticizer provided by the invention has the advantages of no poison, environment protection, better quality and lower cost.

Description

technical field [0001] The invention relates to a production method of PVC (polyvinyl chloride) gloves. Background technique [0002] At present, the plasticizers used in disposable PVC gloves are mainly phthalates, English name: Phthalates, also known as phthalates, phthalates or phthalates, such as dioctyl phthalate ( DOP) and diisononyl phthalate (DINP), but phthalates have certain toxicity and are potentially carcinogenic. However, existing non-phthalate plasticizers, such as acetyl tributyl citrate (ATBC), are more costly than phthalates, and non-phthalate plasticizers are not as effective as phthalates . Therefore, it is necessary to provide a production method for PVC gloves using non-phthalic plasticizers, so as to achieve the purpose of producing PVC gloves with low toxicity, environmental protection, better quality and lower cost. Contents of the invention [0003] The purpose of the present invention is to provide a method for producing PVC gloves using non-p...
