Abstract

The invention discloses a preparation method of a low-temperature-resistant mineral water bottle cap. The bottle cap is prepared from a main material, i.e., a ternary mixed resin material, wherein polyethylene resin has good low temperature resistance; the mechanical property of modified plastics is improved by introducing acrylonitrile butadiene styrene (ABS) resin into the polyethylene resin and polypropylene resin, and the disadvantage of poor solvent resistance of the ABS resin is overcome by using a compatilizer containing a specific component. According to the preparation method, the bottle cap is prepared by adopting a compression molding processing method, and the compression molding processing method has the advantages of lower temperature and small amount of shrinkage, so that the size of the prepared cap is more accurate; all mold cavities for compression molding are relatively independent, thus being separately replaced. A plasticizer prepared by using a specific process is matched with a proper weather-resistant agent, a proper toughening agent and a proper anti-cracking agent for use, so that the toughness and weather resistance of the modified plastics are further improved, and the application temperature range of the modified plastics is greatly increased. Nano antimony tin oxide subjected to ultrasonic treatment is added into the mineral water bottle cap, so that not only is the low temperature resistance of the plastics improved, but the required service life and functions of the plastic bottle cap are also maintained.

Description

technical field [0001] The invention relates to the field of bottle cap manufacturing, in particular to a method for preparing a low-temperature resistant mineral water bottle cap. Background technique [0002] Mineral water is a fast-moving consumer product with a huge market today. Commercially available mineral water is mostly filled with plastic bottles and sealed with plastic bottle caps. In terms of material, it is generally divided into PP and PE. PP materials are mostly used for gas beverage bottle cap gaskets and bottle caps. They are heat-resistant and non-deformable, have high surface strength, and good chemical stability. The disadvantages are poor toughness, easy embrittlement at low temperature, and poor oxidation resistance grind. Bottle caps of this material are mostly used for fruit wine and carbonated beverage bottle cap packaging. PE materials are mostly used for hot-fill bottle caps and aseptic cold-fill bottle caps. This material is non-toxic, has go...
