Embodiment 1

[0042] Example 1: Preparation of polyether ether ketone / gadolinium oxide composite material

[0043] Composition of the composite material: PEEK, sulfonated PEEK, gadolinium oxide.

[0044] First, prepare sulfonated polyetheretherketone: 30g polyetheretherketone is dispersed in 300ml concentrated sulfuric acid, mechanically stirred in a water bath at 40°C for 8 hours for sulfonation, and the whole experiment is under a nitrogen environment; the polymer is poured into ice water to form The product is in the form of filaments, crushed and washed with distilled water until the filtrate becomes neutral, and then baked in an oven at 80°C for 24 to 36 hours to obtain sulfonated polyether ether ketone with a sulfonation degree of 73%.

[0045] Next, prepare modified gadolinium oxide: take 4 g of sulfonated polyether ether ketone and dissolve it in distilled water at 80 ° C, disperse 200 g of gadolinium oxide in the sulfonated polyether ether ketone solution, stir mechanically for 4 h...

Embodiment 2

[0050] Example 2, change the addition amount of sulfonated polyether ether ketone to 2 g in Example 1, and change the addition amount of polyetherether ketone to (100-1.01X) parts, and the polyether ether ketone / gadolinium oxide composite can also be prepared Materials, composite materials have good mechanical properties and good thermal stability.

Embodiment 3

[0051] Example 3, changing the addition amount of sulfonated polyetheretherketone to 8g in Example 1, and changing the addition amount of polyetheretherketone to (100-1.04X) parts, the same can prepare polyetheretherketone / gadolinium oxide composite Materials, composite materials have good mechanical properties and good thermal stability.

Abstract

The invention relates to a polyether-ether-ketone composite material containing gadolinium oxide and a preparation method of the composite material, which belong to the technical field of special engineering plastics. The polyether-ether-ketone composite material comprises the following raw materials in parts by weight: 5-35 parts (X) of the gadolinium oxide, 0-0.08X of sulfonated polyether-ether-ketone and the balance of polyether-ether-ketone. The preparation method of the composite material comprises the following steps of: modified treatment of the gadolinium oxide and melt blending of the raw materials, wherein the modified gadolinium oxide and the polyether-ether-ketone are mixed together, and a double-screw extruding machine is used for carrying out the melting blending on the mixture to obtain the composite material. In order to improve interaction between two phases of the polyether-ether-ketone and the gadolinium oxide in the composite material, the sulfonated polyether-ether-ketone is firstly added into the gadolinium oxide to modify the gadolinium oxide, and then the melt blending is carried out on the mixture, so that the gadolinium oxide can be dispersed well in the polyether-ether-ketone matrix. The composite material has higher strength and modulus, excellent heat stability and a favorable X-ray shielding property.

Description

Technical field: [0001] The invention belongs to the technical field of special engineering plastics, and specifically relates to a polyether ether ketone composite material containing gadolinium oxide (polyetheretherketone / gadolinium oxide composite material) and a preparation method thereof. Background technique: [0002] With the rapid development of modern science and technology, various high-energy rays have been more and more widely used in military, communication, medical, industrial and agricultural fields and in daily life. But when bringing convenience to people, various rays have also brought some harm to people's health. Therefore, the development, production and application of radiation protection materials is one of the key points of civilian medical and health protection work, and is also an important part of radiation protection in the field of nuclear energy development and military fields. The ray-absorbing substances contained in traditional polymer ray-s...
