Description
Technical Field
The invention relates to the field of polymer composite materials, in particular to a transparent weather-proof halogen-free flame-retardant PC/PETG alloy material and a preparation method thereof.
Background
The polycarbonate is an engineering plastic with good transparency, has excellent comprehensive performance and extremely wide application, and the product of the polycarbonate is widely applied to the technical fields of electronic appliances, automobiles, machine manufacturing, computers and the like. However, polycarbonate materials have high melt viscosity, poor flowability, easy stress cracking, poor solvent resistance, easy cracking and swelling in solvents, and poor surface scratch resistance, and these disadvantages limit the application range of PC to some extent. In addition, unmodified polycarbonate has insufficient flame retardancy and cannot meet the requirements of high flame retardancy grade or high flame retardancy grade.
Polyethylene terephthalate-1, 4-cyclohexanedimethanol ester (PETG), a transparent, amorphous copolyester, is a product of the ester exchange polycondensation of three monomers, namely terephthalic acid (PTA), Ethylene Glycol (EG) and 1, 4-Cyclohexanedimethanol (CHDM). PETG has more 1, 4-cyclohexanedimethanol comonomer compared with PET and more ethylene glycol comonomer compared with PCT, so the performance of PETG is greatly different from that of PET and PCT. The PETG sheet material has outstanding toughness and high impact strength, has better viscosity, transparency, color, chemical agent resistance and stress whitening resistance, and is a new-generation environment-friendly plastic. However, because of its low strength and heat resistance and general flame retardant property, PETG greatly limits its application field.
Chinese patent document CN104672880A "a PC/PETG alloy material and a preparation method thereof" discloses a PC/PETG alloy material, and discloses a PC/PETG alloy material, which comprises the following components in percentage by mass: 25-47% of PC, 40-60% of PETG (polyethylene terephthalate glycol), 3-7% of acrylate toughening compatilizer, 5-13% of inorganic powder subjected to surface treatment, 0.3-1% of antioxidant and 0.2-1% of lubricant, wherein the sum of the mass percentages of the components in the PC/PETG alloy material is 100%. The alloy material disclosed by the invention has the advantages of good toughness, high strength and heat resistance, basically no edge warping of a 3D printing molded product, good bottom plate adhesion property and no cracking phenomenon, so that the 3D printing product not only has good physical properties, but also has the advantages of 3D printing formability, good appearance and the like, and the application field of PC materials in the 3D printing industry can be developed. The alloy material obviously improves the heat resistance of the material, reduces the difficulty of 3D printing, forming and processing, but does not improve the flame resistance and weather resistance of the material.
Chinese patent document CN106084708A, a polyester resin-based flame-retardant light diffusion composite material, discloses a polyester resin-based flame-retardant light diffusion composite material, which is prepared by mixing the following raw material components in parts by weight: 100 parts of matrix resin, 0.3-1.5 parts of light diffusant, 0.1-0.6 part of antioxidant, 0.1-0.5 part of release agent and 0.2-8 parts of flame retardant; the matrix resin is formed by combining 30-90% of polycarbonate and 10-70% of polyester terephthalate by weight percentage, wherein the polyester terephthalate is selected from one or more of PET, APET and PETG. The invention comprehensively utilizes the advantages of a plurality of resins, makes up for the deficiencies, overcomes the defects of poor notch sensitivity, poor organic chemical resistance and the like of the traditional PC resin for the LED, and has good flame retardant effect; the cost of the light diffusion material for the LED is greatly reduced, and the LED lighting system has positive promotion effect on the convenience brought by the modern science and technology when the LED lighting system enters the ordinary family for a long time. The alloy material disclosed by the invention patent is characterized in that the flame retardant is one or more selected from perfluorobutyl sulfonate, potassium p-diphenylsulfone sulfonate, polymethylsiloxane, phenyltrimethoxysilane and brominated polycarbonate. Among them, brominated polycarbonate has the best flame retardant efficiency, but generates carcinogenic substances such as tetrabromodibenzoxaoxane and tetrabromobibenzofuran during combustion and thermal cracking, and although it is environmentally friendly, sulfonate and polysiloxane flame retardants cannot meet the flame retardant requirements of thin-walled parts, which has been verified in examples 1-2 of the patent. In addition, the heat resistance, weather resistance and low temperature performance of the material are not improved, so that the outdoor use of the material is limited.
Chinese patent document CN105419260A 'A Cold-resistant high-gloss PC/PBT/PETG alloy material and a preparation method thereof' provides a cold-resistant high-gloss PC/PBT/PETG alloy material, which comprises the following components in percentage by mass: PC 15-30%; PBT 10-20%; 35-60% of PETG; 5-8% of toughening compatilizer; ester exchange inhibitor 0.2-1%; 4-10% of inorganic mineral powder; 0.3 to 0.8 percent of antioxidant; 0.2 to 1 percent of lubricant. The cold-resistant high-gloss PC/PBT/PETG alloy material disclosed by the invention has the advantages of high strength, high low-temperature impact strength, high surface gloss and higher heat resistance, and the characteristic of material buckling deformation is improved, so that the cold-resistant high-gloss PC/PBT/PETG alloy material can be successfully applied to the fields of intelligent IC cards and 3D printing consumables. The PC/PBT/PETG material disclosed by the invention improves the heat resistance and low-temperature performance of the material, but does not improve the flame retardance and weather resistance of the material.
Chinese patent document CN105924922A 'A transparent flame-retardant PC composite material and a preparation method thereof', discloses a transparent flame-retardant PC composite material and a preparation method thereof. The transparent flame-retardant PC composite material comprises the following components in percentage by mass: aromatic PC 48-75%; 10-20% of siloxane-PC copolymer; 5-20% of PETG resin; 5-10% of flame retardant; 0.2 to 1 percent of antioxidant; 0.2 to 1 percent of lubricant. The transparent flame-retardant PC composite material prepared by the invention adopts PC/Si-Pc/PETG blending, well combines the advantages of the three materials, and has the characteristics of good fluidity, low-temperature injection molding, high transparency, good wear resistance, chemical solvent resistance and the like. The adopted fire retardant is 2,4, 6-tribromophenoxy end-capped tetrabromobisphenol A carbonic ester oligomer, and carcinogenic substance hazards such as tetrabromodibenzoxaoxane, tetrabromobisphenol dibenzofuran and the like are generated in the combustion and thermal cracking processes. In addition, the weather resistance and low temperature performance of the material are not evaluated.
Therefore, on the premise of ensuring the light transmittance of the material, how to develop a PC/PETG composite material with weather resistance, halogen-free flame retardance and good low-temperature performance is worth of continuous efforts and exploration.
