Embodiment 1

[0040] The present embodiment relates to a kind of graphene-nitrile latex composite slurry and preparation method thereof; The preparation of nitrile latex comprises the steps:

[0041]Step 1. Sulfur 1kg, zinc oxide 4kg, accelerator (zinc dibutyldithiocarbamate) 1kg, antioxidant (2-6-di-tert-butyl p-cresol) 0.4kg, ethylamine 0.35kg, dispersed Agent (sodium methylene bis-naphthalene sulfonate) 0.4kg, casein 1kg, demineralized water 7.5kg mix uniformly, ball milling speed is 40 revs / min, and ball milling time is 72 hours, forms standby ball milling sulfur material;

[0042] Step 2, in 1 ton of nitrile rubber, add bromododecane modified graphene oxide and synergist ethanolamine, its weight ratio is 100: 0.2: 0.1, mix uniformly, get graphene-nitrile latex;

[0043] Step 3, adding 50 kg of ball-milled sulfur material to be used in the graphene-nitrile latex, stirring for 4 hours, parking for 24 hours, and pre-vulcanizing;

[0044] Step 4, add filler (calcium carbonate) to the slur...

Embodiment 2

[0054] This embodiment relates to a kind of graphene-nitrile latex composite slurry and preparation method thereof; The preparation step of nitrile latex is the same as embodiment 1, and difference is:

[0055] In step 2, in 1 ton of nitrile rubber, add cationic surfactant modified graphene oxide (hexadecyltrimethylammonium chloride modified graphene oxide) and synergist Span, its weight ratio is 100 : 0.025: 0.01, mixed uniformly to obtain graphene-nitrile latex;

[0056] In step 4, add filler (calcium carbonate) and stir after 3 hours in the slurry that pre-vulcanization obtains, add the titanium dioxide slurry that accounts for 3% of acrylonitrile-butadiene rubber weight and stir until even; Described titanium dioxide slurry is the mass ratio It is formed by separate ball milling of 1:1 titanium dioxide and soft water for 72 hours.

[0057] The nitrile latex that does not add cationic surfactant modified graphene oxide is marked as comparative example 3; The graphene-nitri...

Embodiment 3

[0062] The present embodiment relates to a kind of graphene-nitrile latex composite slurry and preparation method thereof; The preparation steps of nitrile latex are the same as embodiment 2, the difference is:

[0063] Step 1. Sulfur 2kg, zinc oxide 11.2kg, accelerator (zinc dibutyldithiocarbamate) 3.2kg, antioxidant (2-6-di-tert-butyl p-cresol) 1.6kg, ethylamine 1.2kg 1.6kg of dispersant (sodium methylene bis-naphthalene sulfonate), 3.2kg of casein, 16kg of demineralized water are mixed evenly, and the ball milling speed is 50 revs / min, and the ball milling time is 48 hours to form the standby ball milling sulfur material;

[0064] Step 2, in 1 ton of nitrile rubber, add amino polymer modified graphene oxide (adopting triethylenetetramine and ethylenediamine, graphene oxide is modified with condensation agent method) and synergist Tween, its The weight ratio is 100:5:0.2, mixed uniformly to obtain graphene-nitrile latex;

[0065] Step 3, add 40kg of ball-milled sulfur mater...

Abstract

The invention discloses graphene-butadiene-acrylonitrile latex compound slurry and a preparation method and application thereof. The compound slurry comprises the following components in parts by weight: 100 parts of butadiene-acrylonitrile rubber and 0.025-5 parts of graphene. The compound slurry also comprises 4-6 parts of a ball-milled sulfur material. Based on the total weight of the ball-milled sulfur material, the ball-milled sulfur material comprises the following components in percentages by weight: 5-8% of sulfur, 22-28% of zinc oxide, 5-8% of an accelerant, 2-4% of an anti-ageing agent, 1.5-3% of ethylamine, 2-4% of a dispersant, 5-8% of casein and 40-55% of soft water. A pair of graphene-butadiene-acrylonitrile latex gloves prepared from the composite slurry is flexible in texture, comfortable to wear, high in tear strength, antibacterial, antistatic, small in stress at definite elongation and good in anti-ageing property, and fully exerts the advantages of graphene which is high in conductivity, high in strength, resistant to friction, high in bacteriostatic property, and the like.

Description

technical field [0001] The invention relates to the technical field of safety protection, in particular to a graphene-nitrile latex composite slurry and its preparation method and application. Background technique [0002] There are several types of oil-resistant gloves currently used in industry, such as rubber oil-resistant gloves, plastic oil-resistant gloves and latex oil-resistant gloves. Among them, the hand shape of rubber oil-resistant gloves is straight, the texture is hard, and it is very inconvenient to wear other hands; the plastic oil-resistant gloves have the weakness of plastic products, which are hard and brittle in winter, easy to age, have a short life, and are relatively expensive; the texture of latex gloves Relatively soft and comfortable to wear, especially nitrile latex gloves have better oil resistance, acid and alkali resistance, abrasion resistance and puncture resistance than natural latex gloves and neoprene latex gloves. , Oil-resistant gloves f...
