Abstract

The invention discloses an environment-friendly and flame-retardant PET-PC (polyethylene terephthalate - polycarbonate) alloy material and a preparation method thereof. The environment-friendly and flame-retardant PET-PC alloy material comprises the following components in percentage by weight: 55% to 70% of PET slices, 15% to 25% of PC particles, 5% to 8% of phosphate ester type flame retardant, 3% to 4% of thermoplastic elastomer, 0.6% to 1% of antioxidant, 0.1% to 0.2% of lubricant, and 2% to 4% of compatilizer. The environment-friendly and flame-retardant PET-PC alloy material has the advantages that by selecting the components and reasonably proportioning, the advantages of PET material and PC material are simultaneously realized; the cracking-resistant strength is high, the tensile-resistant property is high, the heat-resistant, abrasion-resistant and corrosion-resistant properties are realized, the processing fluidity is good, and the mechanical and chemical comprehensive properties are better; the processing technology is improved, and is more reasonable and scientific, so that the cost is reduced, the energy consumption is decreased, and the environment-friendly and energy-saving effects are realized.

Description

technical field [0001] The invention relates to an alloy material, which belongs to the technical field of polymer materials, in particular to an environmentally friendly flame-retardant PET-PC alloy material and a preparation method thereof. Background technique [0002] PET is a high polymer, which is derived from the dehydration condensation reaction of ethylene terephthalate. Because of its unique corrosion resistance, high tensile strength and tear strength, and good durability, PET materials, Chemical properties and stable size, can be safely applied to various electrical appliances, electric tools, large machinery, etc., especially suitable for durable, outdoor labels; but PET alone has poor heat resistance. PC is a kind of tough thermoplastic resin. PC has the advantages of high strength and elastic modulus, high impact strength, and wide temperature range. It is tasteless, odorless and harmless to the human body, but it is easy to crack, has poor processing fluidity...
