Flame retardant plastic and preparation method thereof

Abstract

The invention discloses flame retardant plastic. The flame retardant plastic comprises the following raw materials in parts by weight: ABS, metallocene polyethylene, guar gum, medical stone, a silanecoupling agent, a plasticizer, an antioxidant, diacylglycerol, antibacterial nano titanium dioxide, ricinoleic acid, expanded graphite, alumina, silicon oxide, glass fiber, a bromine-containing flameretardant, a phosphorus-containing flame retardant, expanded graphite, maleic anhydride, phthalic anhydride, formamide and cinnamon extract powder. The bromine-containing flame retardant and the phosphorus-containing flame retardant have a synergistic effect on the flame retarding effect, the flame retardant property of the polypropylene plastic can be enhanced, and the polypropylene plastic is enabled to have good mechanical properties and heat resistance. The flame retardant plastic is simple in materials, abundant in sources, and low in price; and good antibacterial ability is achieved through the addition of the cinnamon extract powder, low-density polyethylene and the cinnamon extract powder form hydrogen bonds or covalent bonds, and ensile strength and elongation at break of a plastic film are improved.

Description

technical field [0001] The invention relates to the technical field of plastic preparation, in particular to a flame-retardant plastic and a preparation method thereof. Background technique [0002] Plastic has good stability and electrical insulation. With the expansion of its application field, the demand for processing also increases, and the requirements for plastic are getting higher and higher. Due to the flammability of plastic itself, corresponding regulations have been made on its flame retardant level and the countries that pollute the environment. Therefore, the brominated flame retardants commonly used in the past have gradually disappeared from people's sight. The flame retardant of the phosphorus nitrogen system has filled some of the vacancies, and it has also enabled the phosphorus nitrogen system flame retardants to occupy a certain market in the flame retardant industry, thereby promoting the rapid development of halogen-free flame retardants.

Problems solved by technology

[0003] There are many flame-retardant plastics, all of which are modified on the basis of raw materials, such as flame-retardant ABS, flame-retardant HIPS, flame-retardant PP, flame-retardant PE, flame-retardant PET, flame-retardant PBT, flame-retardant PC, flame-retardant Combustible PC / ABS alloys, etc., are now mainly halogen-free flame-retardant, and there are many researches on halogen-free flame-retardant, but product stability and flame-retardant effect need to be improved, the production preparation process is relatively cumbersome, and the cost of raw materials is high.
