Abstract

The invention discloses a production method of maleic anhydride grafted polyethylene wax, which comprises the following steps: maleic anhydride, activator and polyethylene wax powder are uniformly mixed in a high-speed mixer; then the mixture enters a multifunctional rubber-plastic processing device, and grafting reaction is carried out on the maleic anhydride and the polyethylene wax powder underthe common action of microwave and the activator to prepare the maleic anhydride grafted polyethylene wax. The activator is introduced to promote the microwave reaction efficiency, improve the grafting rate of maleic anhydride grafted polyethylene wax and greatly improve the compatibility of maleic anhydride grafted polyethylene wax products.

Description

technical field [0001] The invention relates to a production method of maleic anhydride grafted polyethylene wax, belonging to the technical field of polymer wax graft modification. Background technique [0002] Polyethylene wax is a low-molecular-weight polyethylene with a molecular weight of 1000-5000, which is obtained from several sources such as high-molecular polymer cracking, organic monomer polymerization, and high-molecular polymer production by-products. Widely used in daily chemical, leather, ink, plastic, textile, construction, machinery and other fields. Grafting modification of polyethylene wax to give it more excellent solvent dispersibility, pigment dispersibility, lubricity, water dispersibility and other properties has always been paid attention to. [0003] Maleic anhydride graft modified polyethylene wax is an important technical means. The raw material of maleic anhydride has wide sources, economical price and strong reactivity. For polyethylene waxes...
