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

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 a preparation method of antimony trioxide masterbatch. 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 concentration of flam...
