Abstract: The invention relates to the technical field of flame-retardant plastics, in particular to an environment-friendly flame-retardant plastic master batch capable of preventing from blooming and precipitation and a preparation method therefor. Ammonium polyphosphate and melamine polyphosphate are composited and micronized, and the surface of the micronized composite powder is coated to form an aluminum hydroxide coating film. Silicone powder is formed in the coating film while the aluminum hydroxide coating film is formed, and then is subjected to twin-screw extrusion and granulation with a filler, a lubricating additive, silicone oil, polypropylene, and a compatilizer to obtain an environment-friendly flame-retardant plastic master batch that prevents from blooming and precipitation. A aluminum salt solution is converted into the aluminum hydroxide coating film, and the dispersed silicone powder is stably coated on the surface of ammonium polyphosphate in advance, ensuring excellent hydrophobicity to the ammonium polyphosphate, and thereby enhancing the dispersibility and compatibility of the flame retardant in plastics. In particular, silicone powder has good stability and non-migration. After the coated ammonium polyphosphate is stabilized, blooming and precipitation can be effectively prevented.

IPC: G10G5/00
Filed: 2020-05-15
Abstract: Provided is a guitar performance support rod having a support point on a ground. An external force and a weight of a guitar body are practically divided and balanced by means of a single linear telescopic support. A structurally simple damping connection manner is used to enable a performer to play a guitar by gently supporting the guitar instead of holding the guitar by themselves. (As shown in figure 1) A handle screw 30 (as shown in figure 1) is rotated to adjust a telescopic rod 23 within a large vertical range, so as to meet requirements of different guitar playing postures and different seat heights. A handle screw 14 is adjusted to enable the guitar body to rotate to the left or right relative to an abdomen of the performer, thereby achieving large height adjustment of a guitar head. A required inclination of the guitar body is realized by a synchronized inclination movement of the guitar body and the stand. The support rod has a compact design, is collapsible for portability and storage in a case, can be quickly put away, does not occupy much space during performance, and enables easy and fast adjustment for a desired performance posture in a performance environment.
