Abstract
The invention relates to flame-retardant and antistatic material for the shell of a handheld Raman spectrometer, belongs to the technical field of spectrometer shell materials, and aims to solve the problems that the low-molecule phosphorus-nitrogen flame retardant and antistatic agent in the traditional flame-retardant and antistatic ABS materials are prone to hydrolysis and precipitation, and lasting flame-retardant and antistatic effects cannot achieve. A preparation method of the flame-retardant and antistatic material includes: evenly mixing ABS, flame-retardant and antistatic agent, toughening agent and antioxidant, using a double-screw extruder to perform melt mixing and extrusion pelletizing to obtain the flame-retardant and antistatic material. The flame-retardant and antistatic material is good in processing performance, lasting in flame-retardant and antistatic performances and capable of being used as the shell material of various handheld Raman spectrometers.
Description
Technical field
The present invention relates to a kind of handheld Raman spectrometer housing flame-retardant and anti-static material, belong to spectrogrph case material technical field.
Background technology
Acrylonitrile-butadiene-styrene copolymer (ABS), as one of engineering plastics five kinds important, possesses excellent physical and mechanical properties, good resistance to impact and dimensional stability, is used widely in handheld Raman spectrometer sheathing material.But ABS there is also certain problem, material itself is inflammable, be difficult to antistatic, becomes most problem demanding prompt solution in ensureing the application of handheld Raman spectrometer long-term stability.
Current flame-retardant and antistatic ABS material improves the fire resistance of ABS mainly through interpolation Halogen or phosphor nitrogen combustion inhibitor in the ABS course of processing, adds the mode of antistatic additive to improve ABS antistatic property simultaneously.Releasing more smog and enrichment possible in vivo when halogen containing flame-retardant is due to burning, application prospect causes anxiety, and more flame-proof ABS product turns to use halogen-free flame retardants.Halogen-free flame-proof antistatic ABS material reaches flame retardant effect mainly by the mode producing cigarette less phosphor nitrogen combustion inhibitor when adding burning, and its antistatic effect is generally realized by the mode of additional antistatic additive.But people find in the prolonged application of plastic, traditional phosphor nitrogen combustion inhibitor and antistatic additive mostly are little molecule, the i.e. relative molecular weight chemical substance lower than 1000, because molecular polarity and chemical bond, in prolonged application, facile hydrolysis, the problem easily precipitated out is there is with ABS matrix, thus bringing the loss of fire resistance and antistatic property, impact uses.
Summary of the invention
It is an object of the invention to fundamentally overcome the facile hydrolysis of low molecule phosphor nitrogen combustion inhibitor and antistatic additive existence in tradition flame-retardant and antistatic ABS material, easily precipitate out, be difficult to reach persistently fire-retardant and anlistatig problem, thus providing a kind of handheld Raman spectrometer housing flame-retardant and anti-static material.
