Abstract
The invention discloses an antibacterial PET (polyethylene terephthalate) composite material with modified mineral slag. The antibacterial PET composite material is prepared from raw materials in parts by weight: 900-980 parts of PET, 2-3 parts of antioxidant BHT (Butylated Hydroxytoluene), 1-2 parts of antioxidant 168, 5-6 parts of barium metaborate, 2-3 parts of polyisobutylene, 0.3-0.8 part of copper oxide, 0.6-0.8 part of lithium carbonate, 1.5-2.8 parts of zinc molybdate and 3-6 parts of modified antibacterial mineral slag. The antibacterial PET composite material contains the waste mineral slag which is firstly soaked in clear water to remove toxic substances, is then calcined and modified and is finally compounded with antibacterial materials such as zinc oxide and the like to obtain antibacterial powder, and the antibacterial powder is added into the composite material, so that the waste materials are changed into things of value, and the antibacterial PET composite material has the advantages of economization, environment friendliness and good antibacterial effect.
Description
Technical field
The present invention relates to PET packaging vessel field, is exactly a kind of antibacterial PET matrix material that contains Treated By Modified Slag and preparation method thereof and uses thereof.
Background technology
In recent years, due to the good stretch-blow performance of PET and good gas barrier properties, it progressively replaces the packing containers that PE, PP material are widely used in beverage, makeup.The forming method of PET bottle is mainly divided into single stage method (note stretch blow) and two-step approach (stretch-blow), but no matter be single stage method or two-step approach, they are all manufactured by the technique of injection bottle embryo, preheating bottle embryo, stretching, blow molding, by a bottle embryo of injecting, all will be preheating to the T of material
gabove just can carry out stretch blow-molded.
Summary of the invention
The present invention aims to provide a kind of antibacterial PET matrix material that contains Treated By Modified Slag.
Above-mentioned purpose realizes by following scheme:
An antibacterial PET matrix material that contains Treated By Modified Slag, is characterized in that: it is that raw material by following weight parts makes:
