Embodiment Construction

[0015] 1. Preparation of dispersants and related reagents

[0016] The preparation of protective agent casein, diffusing agent NNO, stabilizer potassium hydroxide, surfactant and emulsifier is carried out according to the conventional natural rubber latex glove preparation method, and the general concentration requirements are:

[0017] A. Protective agent casein and diffusing agent NNO are 10-20%,

[0018] B. The concentration of stabilizers, emulsifiers and surfactants is 20%-25%.

[0019] 2. Dispersion Preparation

[0020] The main dispersions used in this system are: sulfur (S), zinc oxide (ZnO), accelerator ZDC, accelerator BZ, whitening agent TiO2, etc.

[0021] The preparation of the dispersion requires grinding with a ball mill or a sand mill, in which sulfur (S) must be ball milled, and the ball milling time is generally required to be more than 72 hours, and the speed of the ball mill tank is generally 100±10 rpm.

[0022] Other materials can be ground with a sand...

Abstract

The invention discloses a manufacturing method of nitrile rubber medical gloves, which comprises the following steps: A. preparation of rubber material: mixing two kinds of nitrile rubber latex, the mixing volume ratio is 30:70~70:30; B. pairing the rubber material Pre-vulcanization; C. Forming; D. Vulcanization; E. Surface treatment. The present invention adopts mixed nitrile latex as raw material, adjusts the ratio of raw materials, and improves specific parameters and process in the production process, so that the produced nitrile medical rubber gloves have good softness, low modulus of elongation and good breaking strength , so that the product can be used not only for general industrial use, but also for medical inspection. It fully meets the relevant requirements of the national standard GB7543-1996 for natural rubber medical gloves. It can be used in medical operations, comfortable to wear, and has good strength and aging resistance. Excellent, wear-resistant, good solvent resistance, good oil resistance and many other advantages.

Description

technical field [0001] The invention relates to a manufacturing method of rubber gloves, in particular to the manufacturing of nitrile rubber medical gloves. Background technique [0002] Nitrile rubber gloves do not cause allergies because they do not contain protein, and their oil resistance, solvent resistance, and aging resistance have obvious advantages over natural rubber latex gloves. There are few reports on the production technology of nitrile rubber gloves in China, especially the reports and literature of nitrile rubber medical gloves. And the common practice of existing nitrile gloves is mainly to take single nitrile rubber latex as raw material, carry out pre-vulcanization by adding a certain amount of pre-vulcanizing agent, utilize ion connection method to carry out film forming, and after the conventional forming process, The gloves are demolded, and the powder-free products are also subjected to conventional turning, chlorination, soaking, and rinsing proces...
