Problems solved by technology

[0003] Polymethyl methacrylate is easy to burn, and its limited oxygen index is only 17.3. It is a pity that it cannot be used in many places where flame retardancy is required.
However, the flame retardant of PMMA is not easy, because PMMA is mostly used in the transparent field, which must not only maintain transparency, but also meet the requirements of fire protection. There are very few such flame retardants! Available flame retardants at home and abroad are: Sandoflame5060, bromophosphate CBP, dimethyl methylphosphonate DMMP, diethylhexyl tetrabromophthalate TBPH, etc. However, these flame retardants should be It is also quite difficult to reach the UL94V0 level, and the added amount often reaches more than 30% or even 40%, which is why there are few flame-retardant transparent PMMA materials on the market

Embodiment example 1

[0038] 1-Pentyl-3-methylimidazolium bromide

[0039]20% of 1-pentyl-3-methylimidazolium bromide compound and acrylic resin pellets were melt-blended with an extruder. The extruder is also equipped with a liquid feeder, and the extrusion temperature is slightly lower than the processing temperature of pure acrylic resin. Then the injection molding machine prepared the samples and tested the flame retardancy.

Embodiment example 2

[0041] N-Butyl-N-methylpiperidinium Bromide

[0042] The processing and testing process of the above implementation case 2 is similar to that of case 1 and will not be repeated here. Wherein, the compound is N-butyl-N-methylpiperidinium bromide compound.

[0043] The flame retardants in the present invention are based on ionic liquid compounds. Ionic liquids refer to salts that are liquid at or near room temperature and are composed entirely of anions and cations, also known as low-temperature molten salts. As an ionic compound, the main reason for the low melting point of ionic liquid is that the asymmetry of some substituents in its structure prevents the ions from stacking regularly into crystals.

[0044] It is composed of organic cations and inorganic or organic anions, the cations are given below figure 1 , There are quaternary ammonium salt ions, quaternary phosphonium salt ions, imidazolium salt ions and pyrrole salt ions. See below for the anions figure 2 , Th...

Abstract

The invention discloses a flame-retardant acrylate plastic, and a preparation method and application of a casting plate thereof. A flame retardant used in the invention comprises an ionic liquid component which may be a single ionic liquid or a mixture of a plurality of ionic liquids or a mixture of an ionic liquid and a traditional flame retardant. A plastic extruded sheet is prepared from a polyacrylic plastic matrix and the flame retardant through blending via an extruder. The flame retardant can also be mixed with acrylic monomers before polymerization so as to obtain the flame-retardant acrylate plastic casting plate. The flame-retardant acrylate plastic plate disclosed by the invention can be used in the fields of lighting products, automobiles, buildings, advertisements and the like.

Description

technical field [0001] The invention belongs to the field of functional materials, and in particular relates to a preparation method of an acrylic plate. Background technique [0002] The polymers obtained by polymerization of acrylic acid and its esters are collectively referred to as acrylic resins, and the corresponding plastics are collectively referred to as polyacrylic plastics, among which polymethacrylate methyl is the most widely used. The abbreviation code of polymethyl methacrylate is PMMA, commonly known as plexiglass. The polymer transparent material is a polymer compound formed by the polymerization of methyl methacrylate. It is an important thermoplastic that was developed earlier. Plexiglass is widely used in construction, advertising, transportation, medicine, civilian products, and industrial applications: instrument panels and covers, etc., and lighting applications: fluorescent lamps, chandeliers, street lamp shades, etc. [0003] Polymethyl methacryla...
