Wall hanging prevention treating fluid as well as preparation method and application thereof

The invention discloses an anti-wall-hanging treating fluid as well as a preparation method and application thereof. The anti-wall-hanging treating fluid is prepared from the following raw material components in parts by weight: 5 to 15 parts of polyvinylpyrrolidone K30, 5 to 15 parts of polyethylene glycol 400, 1 to 10 parts of triethanolamine, 2 to 12 parts of water-soluble polydimethylsiloxane and 800 parts of pure water. The preparation method comprises the following steps: weighing raw materials in a container, adding pure water, uniformly mixing, standing, transferring into a reagent bottle, and covering with a bottle plug for later use. The anti-wall-hanging treating fluid is used for preparing the vacuum blood collection tube. The anti-wall-hanging treating fluid solves the awkward situation that a plastic test tube cannot be silicified due to high temperature, and solves the problem that a glass test tube cannot be labeled due to excessive silicification of the outer wall. 本发明公开了一种防挂壁处理液及其制备方法和应用，所述防
