Problems solved by technology

However, the cold weather in Northeast China restricts the development of BOPP. In winter, the workshop temperature is around 15°C and the humidity is around 25%.
Many products cannot be produced, and the production capacity is far less than 500,000 tons, which seriously restricts the company's development

Embodiment 1

[0025] Modifier preparation

[0026] 75 kilograms of octadecylamine, 8.3 kilograms of N, N-bis (hydroxyethyl) cocamide, 16.7 kilograms of boric acid alkyl alcohol amine esters are added to the high mixer and mixed into the reaction kettle to feed 12.5 kilograms of ethylene oxide Addition reactions give modifiers.

Embodiment 2

[0028] Preparation of antistatic agent AT1

[0029] (1) The weight percent is respectively 12%, 8%, 0.3%, 79.7% modifier, monoglyceride, tris (2,4-di-tert-butyl) phenyl phosphite, and polypropylene are mixed evenly to obtain a mixture material;

[0030] (2) Add the mixture into THJ-high speed and high torque co-rotating parallel twin-screw mixing extruder to melt and extrude to make antistatic masterbatch. Extrusion temperature is 210°C, pressure is 6Mpa, speed is 500rpm, and screw diameter is 75mm. , aspect ratio 40:1;

[0031] (3) cooling and drying the antistatic masterbatch made in step (2), pelletizing;

[0032] (4) The antistatic masterbatch after pelletizing was circulated, dried, mixed and uniformly packed into bags to obtain the antistatic agent AT1.

Embodiment 3

[0034] Preparation of antistatic agent AT2

[0035] (1) Mix modifiers, monoglycerides, tris(2,4-di-tert-butyl)phenyl phosphite and polypropylene with weight percentages of 8%, 12%, 0.3%, and 79.7% respectively to obtain a mixed mixture material;

[0036] (2) Add the mixture into THJ-high speed and high torque co-rotating parallel twin-screw mixing extruder to melt and extrude to make antistatic masterbatch. Extrusion temperature is 210°C, pressure is 6Mpa, speed is 500rpm, and screw diameter is 75mm. , aspect ratio 40:1;

[0037] (3) cooling and drying the antistatic masterbatch made in step (2), pelletizing;

[0038] (4) The antistatic masterbatch after pelletizing was circulated, dried, mixed and evenly packed into bags to obtain the antistatic agent AT2.

Abstract

The invention relates to the technical field of additives for biaxially oriented polypropylene film processing, in particular to an antistatic agent for biaxially oriented polypropylene films in extremely-cold areas and a preparation method of the antistatic agent. The antistatic agent mainly comprises ethoxylation octadecylamine, amides, coco, N, N-bis(hydroxyethyl), monoglyceride, alkyl borate alcohol amine ester, antioxidant and PP, wherein the weight percentage of the monoglyceride is 8-12%, the weight percentage sum of the ethoxylation octadecylamine, the amides, coco, N, N-bis(hydroxyethyl) and the alkyl borate alcohol amine ester is 8-12%, the weight percentage of the antioxidant is 0.3%, and the weight percentage of the PP is 79.7%. The antistatic agent has the advantages that the antistatic agent can be used in the northeastern extremely-cold areas and is evident in antistatic effect and good in technical effect, and the antistatic technical difficulties in the production and application of the biaxially oriented polypropylene films in the northeastern areas are solved.

Description

technical field [0001] The invention relates to an antistatic agent for biaxially stretched polypropylene films in alpine regions and a manufacturing method thereof, belonging to the technical field of processing additives for biaxially stretched polypropylene films. Background technique [0002] Biaxially oriented polypropylene (BOPP) film has the advantages of light weight, non-toxic, odorless, moisture-proof, high mechanical strength, good dimensional stability, good printing performance, good transparency, etc. It is widely used in food, candy, cigarettes, tea , fruit juice, milk, textiles and other packaging fields, has the reputation of "Packaging Queen". The wide application, low pollution and protection of forest natural resources make BOPP film a more popular packaging material than paper and polyvinyl chloride (PVC); the simple and reliable manufacturing process and reasonable price make it a more popular packaging material than two-way film. Stretched polyester (...
