[0003] Hollow microspheres are a new type of inorganic rigid particles. Nowadays, they can be used in many plastic materials to reduce material costs and improve performance to varying degrees. However, hollow microspheres are polar substances that are insoluble in water. When they are used with After the polymers are mixed, due to the difference in polarity, the compatibility between the two will be poor, and some mechanical properties of the composite material will decrease and become brittle, which will bring extreme damage to the processing performance and use performance of the polymer products.

Description

Technical field [0001] The invention belongs to the technical field of plastic processing and preparation, and specifically relates to a preparation method of antibacterial and high temperature resistant plastic particles. Background technique [0002] General-purpose plastics mainly include polyethylene, polypropylene, polyvinyl chloride, polystyrene, ABS (acrylic-butadiene-styrene), polymethyl methacrylate and amino plastics, etc., whose output accounts for the entire plastics output More than 90%, so it is also called a bulk plastic variety. Plastics have excellent properties, many varieties, and a wide range of uses. It can replace the three traditional materials of metal materials, cellulose materials and silicate materials, and is the most powerful competitor of traditional materials. General plastics have been widely used in various sectors such as agriculture, light industry, textiles, electronics, machinery, building materials, packaging and transportation. They have p...
