preparation example Construction

[0023] The specific embodiment of the present invention provides a kind of preparation method of anti-radiation composite latex, comprises the following steps:

[0024] Step 1, barium sulfate, surface modifier, sodium dodecylbenzenesulfonate, sodium methylene dinaphthalenesulfonate and water are processed by ball milling to obtain surface-modified barium sulfate slurry;

[0025] Step 2, mixing the surface-modified barium sulfate slurry, latex and sodium hydroxide solution to obtain a composite latex with a pH of 10-13; wherein, the preparation method of the latex is: rubber latex, sulfur, oxidation Made by mixing zinc, accelerators and antioxidants.

[0026] Further, barium sulfate accounts for 40-80% of the dry mass of rubber latex; the surface modifier accounts for 1-4% of the quality of barium sulfate; sodium dodecylbenzenesulfonate accounts for 3-6% of the quality of barium sulfate ; sodium methylene dinaphthalene sulfonate accounts for 2-6% of the mass of barium sulfate;...

Embodiment 1

[0045]The embodiment of the present invention provides a kind of specific embodiment of radiation-proof composite latex, and the preparation method of radiation-proof composite latex (hereinafter referred to as radiation-proof barium sulfate / butyl rubber composite latex) is as follows:

[0046] (1) Mix barium sulfate powder with deionized water at a mass ratio of 1:1, and add stearic acid with 1% barium sulfate mass, sodium dodecylbenzenesulfonate with 4% barium sulfate mass and barium sulfate mass 4% sodium methylene dinaphthalene sulfonate, ball milled for 6h under the condition of ball milling speed 400rpm to obtain surface modified barium sulfate slurry; add 0.1% of the dry weight of pure butyl latex to pure butyl latex Sulfur, 3% zinc oxide of pure butyl latex dry weight, 0.1% accelerator PX of pure butyl latex dry weight and 0.5% antioxidant DBH of pure butyl latex dry weight and mix homogeneously, And adjust the total solids content to be 50% (wherein the total solids r...

Embodiment 2

[0061] The embodiment of the present invention provides a kind of specific embodiment of radiation-proof composite latex, and the preparation method of radiation-proof composite latex (hereinafter referred to as radiation-proof barium sulfate / butyl rubber composite latex) is as follows:

[0062] (1) Mix barium sulfate powder with deionized water at a mass ratio of 1:1, and add silane coupling agent Si69 with 3% barium sulfate mass, sodium dodecylbenzenesulfonate and sulfuric acid with 5% barium sulfate mass The sodium methylene dinaphthalene sulfonate of barium quality 4%, ball milling 6h under the condition of ball milling speed 500rpm, obtains the barium sulfate slurry of surface modification; Add 0.5% of pure butyl latex dry basis mass in pure butyl latex % sulfur, 3% zinc oxide on a dry basis of pure butyl latex, 0.5% of an accelerator PX on a dry basis of pure butyl latex and 0.5% of an antioxidant DBH on a dry basis of pure butyl latex and mix well , and adjust the total...

Abstract

The invention belongs to the technical field of latex products, and particularly relates to anti-radiation composite latex and a preparation method and application thereof and anti-radiation gloves. The preparation method of the anti-radiation composite latex comprises the following steps that 1, barium sulfate, a surface modifying agent, sodium dodecyl benzene sulfonate, sodium methylene dinaphthalene sulfonate and water are subjected to ball-milling treatment, and a barium sulfate sizing agent with the modified surface is obtained; step 2, the barium sulfate sizing agent with the modified surface, the latex and a sodium hydroxide solution are mixed to obtain the composite latex with the pH value being 10-13; and the preparation method of the latex comprises the step that rubber latex, sulphur, zinc oxide, a promoting agent and an anti-oxidation agent are mixed, and the anti-radiation composite latex is obtained. The anti-radiation composite latex can effectively solve the technical problem that the dispersing stability of current anti-radiation composite latex is still poor.

Description

technical field [0001] The invention belongs to the technical field of latex products, and in particular relates to a radiation-proof composite latex, its preparation method, application and radiation-proof gloves. Background technique [0002] X-rays are widely used in industry, agriculture, medicine and scientific research, but X-ray radiation will cause harm to the health of relevant workers, so people need to use shielding materials to reduce the hazards of X-ray radiation when performing related work . Especially in clinical interventional therapy, nuclear medicine diagnosis and treatment, on the one hand, fine hand manipulation is required, and on the other hand, it is exposed to X-ray radiation environment. Elastic protective gloves are necessary. Traditional lead gloves are thick and have poor softness and ductility, which cannot meet the needs of fine hand manipulation. At the same time, lead also has a relatively large toxic effect on the human body. [0003] Th...
