Problems solved by technology

At present, domestic manufacturers are gradually switching from the earliest imported additives to localized additives due to the high price of imported additives. Because foreign compound additives keep Chinese technology secret, manufacturers hope to have a domestic product instead of imported additives. For unused physical properties, each additive is added separately to achieve the performance index, which results in the destruction of the synergistic effect between the additives, inaccurate additions, unstable product quality, and at the same time, due to separate additions, dust pollution is caused, which endangers health. Dangerous factors that are prone to dust electrostatic hazards

Embodiment 1

[0021] 5kg of antioxidant 330, 44kg of antioxidant 168, 18kg of antioxidant 1076, 5kg of nucleating agent Hyperform HPN-20E, 15kg of acid absorbing agent DHT-4A and 15kg of antistatic agent were used as bis(β-hydroxyethyl) coconut According to the specific gravity, oleylamine is put into the high-speed mixer from light to heavy, and stirred at a speed of 800 rpm for 50 seconds at a temperature of 18-22°C, and then discharged into the conical feeder. It is conveyed to the granulator through the screw, and at each stage of the granulator, the temperature control device is used to control the temperature of each section to prevent the single agent from decomposing and sticking due to the difference in melting point (optimum processing temperature : The temperature of the heating section in the granulator is 55°C, the temperature of the head section is 60°C, and the air cooling temperature is 25°C). The extruded cylindrical strips pass through the conveyor belt air-cooling device ...

Abstract

The invention discloses a high-density polyethylene compound additive and a preparation method thereof, and belongs to the field of chemical engineering. The compound additive comprises an antioxidant, a nucleating agent, an acid acceptor and an antistatic agent, wherein the antioxidant comprises an antioxidant 330, an antioxidant 168 and an antioxidant 1076. The preparation method of the compound additive comprises the following steps: mixing the raw components, and uniformly stirring; granulating the uniformly mixed components so as to obtain granules; and sieving the obtained granules. The compound additive has the advantages that the 5000S-oxidation induction time can be prolonged to above 50 minutes through the synergistic effect among the additives, the yellow index is reduced, the fracture strain is improved, and the like.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a high-density polyethylene composite auxiliary agent and a preparation method thereof. Background technique [0002] With the expansion of the application field of domestic high-density polyethylene products and the improvement of the performance of special high-density polyethylene products, the anti-oxidation performance and other physical properties of its additives are becoming more and more stringent. At present, due to the high price of imported auxiliaries, domestic manufacturers are gradually switching from the earliest imported additives to localized auxiliaries. Because foreign compound auxiliaries keep Chinese technology secret, manufacturers hope to have a domestic product instead of imported auxiliaries, often based on For unused physical properties, each additive is added separately to achieve the performance index, which results in the destruction of the synergist...
