Technical Field
The invention belongs to the technical field of plastic processing treatment, and particularly relates to a preparation method of a plastic release agent.
Background
Along with the development of society and the transformation of consumption concept, people pay more and more attention to body health, so that various fitness equipment in cities and homes are continuously increased, and great convenience and help are provided for the health improvement of people. Common fitness equipment includes a walking machine, a body building vehicle, a rowing machine, a running machine, a waist beautifying machine and the like, and a large number of plastic shells are used in the equipment.
