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 additi

preparation example Construction

[0022] according to figure 1 As shown, a preparation method of a multifunctional plastic additive includes:

[0023] Step S1. Take 60 to 80 parts by weight of aliphatic acrylate urethane oligomer, 5 to 15 parts by weight of acrylate monomer, and 0 to 5 parts by weight of vinyl silicone oil and place it with a stirrer, condenser and In the three-necked flask of an isobaric funnel;

[0024] Step S2: Place the three-necked flask in a temperature-controlled oil bath;

[0025] Step S3: Weigh 0.5 to 2 parts by weight of the free radical initiator, mix it evenly, and place it in an equal pressure funnel;

[0026] Step S4: When the stirrer is in a stirring state, after the oil bath starts to heat to a set temperature, the isostatic funnel starts to drip the initiator solution;

[0027] Step S5: After reacting for a certain period of time, 0.1 to 0.2 parts by weight of antioxidant is added to obtain the auxiliary agent.

[0028] Wherein, the rotation speed of the stirrer during the reaction is ...

Embodiment 1

[0036] Take 60 g of aliphatic acrylate polyurethane oligomer, 10 g of methyl acrylate, and 2 g of vinyl triethoxy silane in a 100 ml three-necked flask with a stirrer, condenser and isobaric funnel. The three-necked flask is placed in the program In a temperature-controlled oil bath;

[0037] Then weigh 0.5 g of dicumyl peroxide initiator, mix it evenly, and place it in an equal pressure funnel;

[0038] When the stirrer is stirring at 200 rpm, the oil bath starts to heat to 165°C, and the isobaric funnel starts to drip the initiator solution at a rate of 30 drops / min;

[0039] After 4 hours of reaction, 168 0.2 g of antioxidant was added to obtain auxiliary agent 1.

Embodiment 2

[0041] Take 60g of aliphatic acrylate polyurethane oligomer, 10g of methyl acrylate, and 2g of vinyltrimethoxysilane in a 100ml three-necked flask with a stirrer, condenser and isobaric funnel. The three-necked flask is placed in a program control In a warm oil bath;

[0042] Then weigh 0.5 g of dicumyl peroxide initiator, mix it evenly, and place it in an equal pressure funnel;

[0043] When the stirrer is stirring at 200 rpm, the oil bath starts to heat to 165°C, and the isobaric funnel starts to drip the initiator solution at a rate of 30 drops / min;

[0044] After 4 hours of reaction, 168 0.2 g of antioxidant was added to obtain auxiliary agent 2.

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.
