Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a processing aid containing rice bran wax and a preparation method thereof. Background technique [0002] Rice bran wax is mainly composed of higher fatty alcohols and higher fatty acid esters. It is non-toxic and harmless. It is usually mixed with other waxes, such as carnauba wax, or used as a substitute for other waxes. Rice bran wax has a wide range of uses, and can be widely used in electrical insulation coatings, wetting agents for leather, wood, and paper, fruit spray preservatives, product surface coating agents, etc. It can be said that rice bran wax is a common and important raw material in the field of industrial processing . [0003] One of the uses of rice bran wax is that it can be used as a component of plastic processing aids for thermoplastics and thermosetting plastics. Plastic processing aids are beneficial to improve resin fluidity, wet dispersibility,...
