Problems solved by technology

[0007] (1) The temperature characteristics are poor. Due to the difference in formula and process, the resin is easy to soften during the use of the product, especially during the temperature rise process, resulting in a decrease in the strength of the product during use, and cracks and failures in the product;
[0008] (2) Poor insulation. Due to differences in formula and process, fillers are prone to sedimentation and agglomeration, which makes the product easy to discharge and breakdown at the agglomeration point during use;
[0009] (3) The shielding performance is poor. Due to the difference in formula and process, it is difficult for the product to reach a high filling level, resulting in insufficient effective lead equivalent, thus insufficient shielding performance;

Embodiment 1-27

[0045] The resin compositions of Examples 1-27 were prepared according to the formulation amounts of each component in Table 2 according to the following steps:

[0046] Step 1. Prepare resin premix according to Table 1;

[0047] Step 2. Weigh the dispersant in proportion and add it to the resin premix obtained in Step 1, stir and mix evenly;

[0048] Step 3. Determine the particle size of the lead metal oxide with a particle size analyzer. Weigh the ratio according to Table 1 to obtain the lead oxide premix, then add this premix to the components obtained in step 3, and disperse while Add to uniform dispersion at high speed;

[0049] Step 4. Determine the particle size of the lead metal powder with a particle size analyzer, and weigh and proportion the resulting lead metal powder into the components obtained in step 3, and disperse while adding, until the high-speed dispersion is uniform;

[0050] Step 5. Weigh the organosilicon defoamer in proportion and add it to the components obta...

Abstract

The invention discloses a ray shielding and high-voltage insulating resin composition, as well as a preparation method and application of the composition. The epoxy resin composition contains lead metal oxide powder having a grain size distributed in ranges of being more than 16 microns, between 10 and 16 microns and less than 10 microns, and lead metal powder having a grain size distributed in ranges of being between 0.5-1.0 micron, between 5-15 micron and between 1.0-5 microns, each kind of powder can form a uniformly distributed structure in the resin, the aggregation phenomenon caused by uneven distribution and uneven grain size can be avoided, pores inside resin can be finally reduced, and the resin material having higher density can be obtained. The composite material has remarkableimprovement in the aspects of insulating strength, ray shielding effect and the like, and has wide application prospect in the fields of X ray source, ray shielding, high-voltage insulating devices and the like.

Description

Technical field [0001] The invention relates to the technical field of radiation shielding and high-voltage insulating resin materials, in particular to a radiation shielding and high-voltage insulating resin composition, and a preparation method and application thereof. Background technique [0002] X-rays are widely used in security inspection, industrial inspection, medical and other perspective fields. X-rays are mainly generated by electrons hitting a metal target after high-voltage acceleration. The device that generates x-rays is an x-ray source. The x-ray source includes: x-ray generator , High-voltage power supply unit, insulated oil tank, control unit, etc. The x-ray generator includes a shielding cover and a ray tube. The shielding cover wraps the x-ray tube. The shielding cover has reserved ray exit windows and electrode lead-out channels. The x-ray generator and high-voltage power supply unit are installed inside the tank full of insulation. , The shielding cover ca...
