Embodiment 1
[0028] This embodiment provides an environmentally friendly flame retardant transparent polyester material, which in parts by mass includes thermoplastic polyester resin (PET) and a flame retardant, and every 100 parts of thermoplastic polyester resin corresponds to 1 part of flame retardant; The flame retardant is a core-shell structure montmorillonite-silicon-fluorine modified polypropylene material, and both montmorillonite and fluorine and silicon elements are located in the core.
[0029] In parts by mass, the flame retardant includes the following raw materials: 50 parts of deionized water, 1 part of initiator, 0.5 part of buffer, 3.5 parts of emulsifier, 2 parts of silane coupling agent, 4 parts of nano-montmorillonite, 2 parts of fluoroolefins; 40 parts of hard monomers, 10 parts of soft monomers; the particle size range of the nano-montmorillonite is 10-30 nm; the emulsifier includes cetyltrimethylammonium bromide and allyloxynonylphenol polyoxyethylene ether sulfate ...
Embodiment 2
[0061] This example is basically the same as Example 1, except that: in parts by mass, the flame retardant includes the following raw materials: 60 parts of deionized water, 2 parts of initiator, 1.0 part of buffer, 4.5 parts of emulsifier, 3 parts of Parts of silane coupling agent, 5 parts of nano-montmorillonite, 3 parts of fluoroolefin; 30 parts of hard monomers, 20 parts of soft monomers; the emulsifier includes sodium dodecylbenzenesulfonate and allyloxynonane ammonium phenol polyoxyethylene ether sulfate, and the ratio is 3:1.5; the fluorinated olefin is fluorinated ethylene; the silane coupling agent is vinyltrimethoxysilane; the soft monomer includes 6 parts of methyl Hexyl acrylate, 9 parts ethyl acrylate; 5 parts butyl acrylate; hard monomers include 10 parts t-butyl methacrylate, 10 parts styrene, 10 parts acrylamide; each 100 parts thermoplastic polyester resin corresponds to 0.8 parts of flame retardant.
[0062] The test method of flame retardant performance is ...
Embodiment 3
[0064] This example is basically the same as Example 1, except that: in parts by mass, the flame retardant includes the following raw materials: 60 parts of deionized water, 1 part of initiator, 0.7 part of buffer, 4.5 parts of emulsifier, 3 parts of Parts of silane coupling agent, 5 parts of nano-montmorillonite, 3 parts of fluoroolefin; 40 parts of hard monomer, 10 parts of soft monomer; the fluoroolefin is tetrafluoroethylene; the silane coupling agent is vinyl triethoxysilane; the soft monomers include 3 parts of hexyl methacrylate and 7 parts of butyl acrylate; the hard monomers include 11 parts of vinyl acetate, 16 parts of methyl methacrylate and 13 parts of styrene; each The 100 parts of thermoplastic polyester resin corresponds to 0.8 part of flame retardant.
[0065] The test method of flame retardant performance is the same as that of Example 1, and the flame retardant performance test of each test in this implementation has reached the V-0 level.
