Preparation method for multifunctional plastic additive

Abstract

A preparation method for a multifunctional plastic additive including following steps: filling a three-necked flask with 60-80 parts by weight of an aliphatic acrylate polyurethane oligomer, 5-15 parts by weight of an acrylate monomer and 0-5 parts by weight of vinyl silicone oil, wherein the three-necked flask is provided with a stirring apparatus, a condensing pipe and a constant-pressure funnel; placing the three-necked flask into an oil bath which is temperature-controlled by program; weighing 0.5-2 parts by weight of a radical initiator with mixing uniformly; feeding the radical initiator into the constant-pressure funnel; when the oil bath heats the three-necked flask to a preset temperature, dropwisely adding the initiator solution from the constant-pressure funnel with the stirring apparatus being in a stirring status; adding 0.1-0.2 parts by weight of an antioxidant after a reaction being carried out for a certain time to obtain the additive. Functions such as coupling, compatibility, dispersion, lubrication and the like are integrated in the multifunctional plastic additive. The multifunctional plastic additive can be used for processing polymer composites, can improve compatibilities of each components in a system well, can promote plastification, can reduce viscosity of a melt, can improve processing fluidity, can reduce a torque of an processing device and processing energy consumption and can improve efficiency.

Description

Technical field [0001] The invention relates to the field of chemical engineering, in particular to a preparation method of a multifunctional plastic auxiliary agent. Background technique [0002] With the development of society and technology, polymer materials have become one of the indispensable materials for mankind. The rapid development of my country's plastics industry has driven the continuous growth of the plastic additives industry. At present, my country's annual output of plastic additives is nearly 1 million tons, and the actual annual consumption exceeds 1.3 million tons, of which the annual import volume is about 300,000 tons. It is expected that in the next 10 noon, the average annual growth rate of my country's plastic additives demand will reach 10 %, and become the world's largest plastic additives market. With the growth of the plastic products market, the requirements for plastic additives are constantly increasing, making it present new development trends i...

Problems solved by technology

[0003] There are many types of plastic additives currently in use. For alloy plastics, filled plastics, and surface treatment of inorganic fillers, common plastic additives include lubricants, coupling agents, and dispersants. However, these plastic additives have single functions. It is very troublesome to add in the process of use, especially in the process of adding dust and processing procedures, which brings great inconvenience to users

Although many documents have also reported and developed new multifunctional plastic additives, for example, patent CN102219928A discloses a multifunctional additive for plastic processing and its preparation method, but its preparation method is mainly through the simple compounding of several materials, The functionality and uniformity of this plastic additive have been greatly challenged; in addition, the patent CN101445620A discloses a multifunctional additive for rubber, but the method for preparing the multifunctional additive is complicated and not environmentally friendly. The process is dangerous and polluting
