Problems solved by technology

These current studies mainly have the following deficiencies: ① When the flame retardant masterbatch is equivalent to the flame retardant powder, it is necessary to increase the amount of the flame retardant masterbatch, and the flame retardant masterbatch needs to be extruded and granulated ② the current processing technology still has dust in the process of high-speed stirring; ③ when the high-stirred antimony trioxide powder is directly extruded and granulated by twin-screw, the powder is relatively heavy The fine content is high, the feeding is difficult, and it will cause greater wear to the barrel and screw

Embodiment 1

[0023] The proportion is made according to the following mass percentage composition: 85% antimony trioxide (0.03μm, Hunan Chenzhou Mining Co., Ltd.), homopolypropylene (PPH) 14% (grade EP500N, CNOOC and Shell Petrochemical Company), modified ethylene Bis fatty acid amide (ethylene bis fatty acid amide grafted with maleic anhydride) 1% (commercially available conventional model). After the above materials are accurately weighed, PPH and modified ethylene bis fatty acid amide are added to the pressurized tumbling internal mixer. The temperature in the internal mixing chamber is controlled to 150℃, the rotor speed is 40r / min, and the mixing time is 3min. After the materials are melted, the nanometer antimony trioxide powder is added to the internal mixer three times, with an interval of 3 minutes each time; after all the materials are added, the mixer is then mixed for 5 minutes. The rubber head after banburying is transported to the hopper of the single-screw extruder by the con...

[0026] Proportioning according to the following mass percentage composition: antimony trioxide 90% (0.05μm, Hunan Chenzhou Mining Co., Ltd.), homopolypropylene (PPH) 8.5% (grade EP500N, CNOOC and Shell Petrochemical Company), modified ethylene Bis fatty acid amide (ethylene bis fatty acid amide grafted with maleic anhydride) 1.5% (commercially available conventional model). After the above-mentioned materials are accurately weighed, PPH and modified ethylene bis fatty acid amide are added to the pressurized tumbling internal mixer. The temperature in the internal mixing chamber is controlled at 150~160℃, the rotor speed is 40r / min, and the mixing time is 5min, after the materials are melted, add the nano antimony trioxide powder to the internal mixer three times, with an interval of 5 minutes each time; after all the materials are added, banbury for 10 minutes. The rubber head after banburying is transported to the hopper of the single-screw extruder through the conveyor belt, ...

Embodiment 3

[0028] Proportioning according to the following mass percentage composition: antimony trioxide 95% (0.08μm, Hunan Chenzhou Mining Co., Ltd.), random copolymer polypropylene (PPR) 4.5% (brand R370Y, South Korea SK company), modified ethylene Double fatty acid amide (ethylene bis fatty acid amide grafted with divinylbenzene) 0.5% (commercially available conventional model). After the above materials are accurately weighed, PPR and modified ethylene bis fatty acid amide are added to the pressurized tumbling internal mixer. The temperature in the internal mixing chamber is controlled to 160°C, the rotor speed is 45r / min, and the internal mixing time is 5 minutes. After the materials are melted, the nanometer antimony trioxide powder is added to the internal mixer three times with an interval of 4 minutes each time; after all the materials are added, the mixer is then mixed for 8 minutes. The rubber head after banburying is transported to the hopper of the single-screw extruder thro...

Abstract

The invention discloses antimony trioxide master batch and a preparation method thereof. The antimony trioxide master batch comprises the following components by mass percent: 85 to 95 percent of nano antimony trioxide, 3 to 14 percent of carrier, and 0.1 to 5 percent of modified ethylene bis-fatty-acid amide. The high-efficiency antimony trioxide master batch prepared by the invention has the characteristics of easiness in dispersion, high flame-retardant efficiency and low production cost, and has smaller influence on the physical and mechanical properties, the heat resistance, the processability and the surface color of a composite material than the traditional antimony trioxide master batch.

Description

technical field [0001] The invention relates to an antimony trioxide masterbatch and a preparation method thereof. Background technique [0002] With the continuous development of the country's economic construction, the use of flame-retardant plastics is becoming more and more extensive, and the requirements for the flame-retardant performance of its plastic materials are also getting higher and higher. Since most of the flame retardants added to plastics are powders, and in order to obtain better flame retardant effects and mechanical properties, the fineness of the powders is generally above 800 mesh, and it is easy to produce a large amount of Dust pollution, worsening the production environment, causing great harm to human health, and will cause a certain degree of wear and tear on processing equipment. [0003] Flame retardant masterbatch is also called flame retardant masterbatch and fireproof masterbatch. It is called "concentrate" abroad, which means the concentra...
