Embodiment 1

[0074] First, SiC whiskers that are 3 parts by weight, compatibilizer 1 that are 3 parts by weight, antibacterial agent 1 that are 0.03 parts by weight, lubricant 1 that is 0.01 parts by weight and tetrakis[methyl-β] that are 0.01 parts by weight -(3,5-di-tert-butyl-4-hydroxyphenyl)propionate]pentaerythritol ester and tris(2,4-di-tert-butylphenyl)phosphite in a 1:1 mixture. Place in a temperature-controlled high-speed blender. Stir at high speed at 90°C for 2 minutes, then add 40 parts by weight of polybutylene terephthalate pellets and 5 parts by weight of acrylonitrile-styrene-acrylic acid terpolymer at room temperature and stir for 2 minutes, and finally mix The last component is put into the extruder. During the extrusion process, 35 parts by weight of glass fiber is added from the glass fiber port, mixed at 255-270°C to obtain a polymer, and the obtained polymer is extruded in a strip shape, and then It is cut into segments to form 2-5mm pellets. The obtained pellets we...

Abstract

The invention relates to a material used for manufacturing a handle of a refrigerator door and a preparation method thereof. The material composition comprises the following components in parts by weight: 40-83 parts of polybutylene terephthalate, 5-25 parts of acrylonitrile- styrene-acrylonitrile composition, 10-35 parts of glass fiber, 3-20 parts of crystal whisker, 2-10 parts of a compatilizer, 0.03-2 parts of an antibacterial agent, 0.01-2 parts of a lubricating agent and 0.01-2 parts of other auxiliaries; and the components are mixed in the formula, and then extrusion pelleting is carried out by virtue of an extruding machine, so that the material composition product is obtained. Compared with the prior art, the material composition provided by the invention is subjected to moulding and processing, the prepared handle of the refrigerator door is smooth and produces no warpage on the surface, no glass fiber is exposed, dimensional stability is good, and the prepared handle of the refrigerator door is resistant to scraping and has excellent antibacterial property.

Description

technical field [0001] The invention relates to the field of polymer materials and their molding processing, in particular to a polybutylene terephthalate (PBT) composition used for preparing refrigerator door handles and a preparation method thereof. Background technique [0002] The door handle of the refrigerator is frequently used in daily life, and needs to be opened and closed frequently all year round, especially sometimes with hands stained with raw meat or other pollutants to open and close the refrigerator, leaving stains inadvertently, which makes the door handle of the refrigerator become bacteria or even Virus breeding grounds. Some people say that the door handle of the refrigerator is one of the ten dirtiest places in the house. The bacteria on it is 200 times that of the toilet seat. It is recommended to clean it with bleach and disinfectant once a week. In view of the special use environment and cleaning requirements, the requirements for the material of th...
