Embodiment 1

[0036] Take each raw material by the following parts by weight:

[0037] Barium sulfate 40, silicon dioxide 30, aluminum oxide 5, strontium oxide 0.5;

[0038] Mix barium sulfate, silicon dioxide, aluminum oxide, and strontium oxide evenly to prepare an X-ray blocking agent for subsequent use;

[0039] Take each raw material by the following weight percentages:

[0040] Fatty alcohol polyoxyethylene ether 0.5 Vinyl silane coupling agent 0.3

[0041] Water-soluble epoxy resin 0.5 Glacial acetic acid 0.02

[0042] X-ray blocking agent 1 The balance is deionized water

[0043] Add a quarter of the total amount of deionized water into the preparation kettle, then add glacial acetic acid, stir evenly for 3 to 5 minutes, make the pH value 2 to 3, then slowly add vinyl silane coupling agent and continue stirring for 50 Minutes, until the surface of the solution becomes clear and oil-free, the speed should not be too fast during the stirring process to avoid bringing air bubbles. ...

Abstract

The invention relates to a preparation method of quartz fiber with X-ray radiation prevention agent coating, and belongs to the technical field of quartz fiber production. Surface of quartz fiber filament is treated using the surface treating agent containing radiation prevention agent, then quartz fiber filament is coiled to quartz fiber strand by the high speed rotation and traction of the head of drawing mill, and finally, the strand is subjected to baking, degradation, pre-twist and cabling to form the final product of quartz fiber yarn with a coating containing radiation prevention agent. The quartz fiber with a coating containing radiation prevention agent made using such method has the strengths of simple techniques and low cost, and can well combined with epoxy, and can be produced to the fiber post with homogeneous X-ray prevention effect.

Description

technical field [0001] The invention relates to a method for preparing a quartz fiber coated with an X-ray anti-radiation agent, and belongs to the technical field of quartz fiber production. Background technique [0002] In stomatological treatment methods, the method of post-core plus full crown is generally used to restore the residual root and crown of the tooth. The material selection of the post has a very important impact on the treatment effect. The post material made of quartz fiber reinforced resin has many advantages: the color is similar to that of teeth, and it is beautiful; the elastic modulus is relatively close to that of dentin, which can effectively transmit and disperse stress and prevent root fracture; it is the same material as nuclear resin material, Can produce chemical bonding; no allergies and corrosion, good biocompatibility; easy to remove, so that secondary repairs can be performed on failed cases of fiber post repairs, effectively preserve the ro...
