Abstract

The invention discloses a preparation method of a plastic slipping agent, which belongs to the technical field of fine chemical industry. Unsaturated components of oleamide such as linoleic acid amideand linolenic acid amide are removed by adopting a skeleton nickel selective hydrogenation method, so that a substance with higher purity which can reduce the viscosity of plastic resin melt and improve the mobility can be obtained, then the obtained oleamide substance is used for modifying 3-gamma-chloropropyl trimethoxysilane, and when the oleamide substance is added in the preparation processof a plastic product, the surface tension of a plastic film is reduced, the wetting angle is reduced, and the wetting effect of the plastics can be improved. As the content of polyether chains is increased, the surface water absorption performance of the plastics is improved, the surface resistivity is reduced, and the antistatic capability is improved. The problems that the existing plastic slipping agent is single in product performance, the plastic film and the plastic product cannot resist the static electricity for a long time and the haze and transparency of the film are severely influenced can be solved.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, and in particular relates to a preparation method of a plastic smoothing agent. Background technique [0002] The slip agent belongs to one of the products in the slip agent technical field. Slip agent is a white or light yellow powder, which is used to enhance the resistance to mechanical stirring and shearing force. The main ingredients are edible colloid, enzyme preparation and emulsifier. Plastic slip agent is a white neutral powdery solid, which has good dispersibility to various substances such as dyes and pigments. In plastic processing, it can play the role of smoothing, lubricating, glazing, demoulding, anti-adhesive, anti-caking, anti-humidity, anti-static, dispersing and increasing the surface brightness of the product, without affecting the transparency and physical properties of the final product. nature. It is an ideal new, high-efficiency, non-toxic plastic processing lu...
