Embodiment 1

[0027] Get 65 grams of polypropylene wax and 20 grams of polyethylene wax and place in the 250ml four-necked flask of condenser, stirrer, equal pressure funnel and thermometer, place the four-necked flask in the electric heater with program temperature control. Take 5 grams of maleic anhydride, 15 grams of vinyltrimethoxysilane, and 1 gram of dibenzoyl peroxide, mix them uniformly, and place them in an equal-pressure funnel. The four-necked flask was heated to completely melt the polypropylene wax and the polyethylene wax, and the temperature in the four-necked flask was controlled at 180°C. Turn on the cooling water in the condensing tube, turn on the stirrer, open the equal pressure funnel valve, start to drop the mixture in the equal pressure funnel, and the speed of dropping is controlled at 150ml / hour. After the dropwise addition, the temperature in the four-neck flask was controlled at 200° C., and after 3 hours of reaction, the cooling water in the condenser tube was tu...

Embodiment 2

[0029] Get 85 grams of polypropylene wax and 10 grams of polyethylene wax and place in the 250ml four-necked flask of condenser, agitator, equal pressure funnel and thermometer, and place the four-necked flask in the electric heater with programmed temperature control. Take 10 grams of maleic anhydride, 5 grams of vinyltrimethoxysilane, and 2 grams of dibenzoyl peroxide, mix them uniformly, and place them in an equal-pressure funnel. The four-necked flask was heated to completely melt the polypropylene wax and the polyethylene wax, and the temperature in the four-necked flask was controlled at 170°C. Turn on the cooling water in the condensing tube, turn on the stirrer, open the valve of the equal pressure funnel, start to drop the mixture in the equal pressure funnel, and the speed of dropping is controlled at 200ml / hour. After the dropwise addition, the temperature in the four-neck flask was controlled at 200° C., and after 3 hours of reaction, the cooling water in the conde...

Embodiment 3

[0031]Get 65 grams of polypropylene wax and 20 grams of semi-refined wax and place in the 250ml four-necked flask of condenser, agitator, equal pressure funnel and thermometer, and place the four-necked flask in an electric heater with programmed temperature control. Take 5 grams of methyl acrylate, 15 grams of vinyltriethoxysilane, and 1 gram of dicumyl peroxide, mix them uniformly, and place them in an equal-pressure funnel. The four-necked flask is heated to completely melt the polypropylene wax and the semi-refined wax, and the temperature in the four-necked flask is controlled at 180°C. Turn on the cooling water in the condensing tube, turn on the stirrer, open the equal pressure funnel valve, start to drop the mixture in the equal pressure funnel, and the speed of dropping is controlled at 150ml / hour.

Abstract

A processing auxiliary agent having compatibility-enabling and coupling functions and a preparing method thereof are provided. The processing auxiliary agent includes, by weight, 65-85 parts of polypropylene wax, 10-30 parts of a modified oligomer, 0-15 parts of an unsaturated functional monomer, 0-5 parts of vinyl silane and 0.5-2.5 parts of a free radical initiator. The processing auxiliary agent integrates compatibility-enabling and coupling functions, has obvious functions in the fields of plastic alloys, plastic filing, inorganic filler surface treatment, and the like, and can improve interfacial force between resin and resin as well as interfacial force between resin and a filler, thus improving appearance quality of a final product and improving macroscopic performance and processing performance of products.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and relates to a processing aid with compatibility and coupling functions and a preparation method. Background technique [0002] With the development of society and technology, polymer materials have become one of the indispensable materials for human beings. The rapid development of my country's plastics industry has driven the growth of the plastic additives industry. At present, the annual output of plastic additives in my country 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 estimated that in the next 10 years, the average annual growth rate of my country's demand for plastic additives will reach 10%, and it will become the world's largest market for plastic additives. With the growth of the plastic product market, the requirements for plastic additives are constantly increasing...
