Embodiment 1

[0025] Embodiment 1: a kind of anti-oil stain and anti-X-ray radiation plexiglass master batch adopts the following components:

[0026] 60 parts by mass of methyl methacrylate, 20 parts by mass of lead methacrylate, 9.95 parts by mass of lead octoate, 0.05 parts by mass of an initiator, and 10 parts by mass of fluoroacrylate.

[0027] In the present embodiment, the anti-oil stain anti-X-ray radiation plexiglass masterbatch is made into plexiglass according to the following preparation method:

[0028] S1, first add the anti-oil stain and anti-X-ray plexiglass masterbatch into the reaction kettle, carry out pre-polymerization in an environment of 80°C to generate a pre-polymerized liquid, and carry out the reaction for 60 minutes, and the liquid to be pre-polymerized becomes viscous When thick as glycerin liquid, stop heating and cool to room temperature quickly;

[0029] S2, pour the pre-polymerized liquid into the mold, put it in an oven at 30°C and keep it warm for 5-7 hou...

Embodiment 2

[0035] Embodiment 2: a kind of anti-oil stain and anti-X-ray radiation plexiglass master batch adopts the following components:

[0036] 75 parts by mass of methyl methacrylate, 10 parts by mass of lead methacrylate, 9.95 parts by mass of lead octoate, 0.05 parts by mass of initiator, 5 parts by mass of fluoroacrylate, and 5 parts by mass of other monomers.

[0037] In this example, the masterbatch is weighed according to the above components, and the X-ray-resistant organic glass is prepared according to the preparation method of Example 1.

[0038] The anti-X-ray plexiglass and ordinary plexiglass were carried out radiation protection test and oil stain resistance comparison test under the same thickness of 2cm, the results are as follows

[0039]

[0040] As can be seen from the above table, this kind of anti-X ray plexiglass is compared with ordinary plexiglass, and oil stain resistance and X-ray ray resistance have greatly improved, and compared with the anti-X ray ray...

Embodiment 3

[0041] Embodiment 3: a kind of anti-oil stain and anti-X-ray radiation plexiglass master batch adopts the following components:

Abstract

The invention discloses anti-oil pollutant X-ray radiation-preventing organic glass masterbatch and relates to the technical field of organic glass. The anti-oil pollutant X-ray radiation-preventing organic glass masterbatch comprises the following components in parts by mass: 60-75 parts of methyl methacrylate, 10-20 parts of lead methacrylate, 5-10 parts of lead caprylate, 5-10 parts of fluoroacrylate and 0.05-0.3 part of an initiator. The method comprises the steps: adding the lead methacrylate, the lead caprylate and the fluoroacrylate into the methyl methacrylate for copolymerization; and pouring the mixture into a mold to form the X-ray radiation-preventing organic glass. By adding the lead salt into the organic glass disclosed by the invention, the X-ray radiation-preventing ability of the organic glass can be improved to a great extent; as fluorocarbon bonds have the characteristics of being short in bond, good in stability, small in intermolecular forces and the like, the hydrophobic and oilphobic and anti-pollution abilities of the organic glass can be improved by adding the fluoroacrylate during polymerization. The invention further discloses the method for preparing the organic glass by using the nti-oil pollutant X-ray radiation-preventing organic glass masterbatch.

Description

technical field [0001] The invention relates to the technical field of plexiglass, in particular to an oil stain-resistant and X-ray radiation-resistant plexiglass masterbatch and a method for preparing plexiglass. Background technique [0002] With the rapid development of industrial and agricultural production, national defense scientific research, radiation medicine and atomic energy industry, the use of various rays is becoming more and more extensive. While using rays, we should also pay attention to the harmfulness of rays. People who are often exposed to radioactive rays will have symptoms such as skin burns, hair loss, eye pain, leukopenia, and even myeloma. Therefore, research on various shielding materials for protecting these rays has become a very important and urgent topic. Great results have also been achieved. Anti-radiation materials refer to materials that can absorb or dissipate radiation energy and protect the human body or instruments. The traditional ...
