Embodiment 1

[0030] (1) Take 0.1 parts of cytosine flame retardant and 90 parts of polypropylene, put them into the internal mixer at 220-230°C and rotate at 120rpm / min to melt and blend for 10-15min, then add 3 parts of antioxidant and 1 part toughening agent, blend for 2-3h.

[0031] (2) Then put the material obtained in the above step (1) on a flat vulcanizer to press the plate, and finally extrude it with a twin-screw extruder. The extruded strip is cooled by a water tank and air cooled, and then introduced into a pelletizer for pelletizing and packaging , and then baked in a dryer for 5-8 hours, and finally injection molded into required test samples at 215-225°C to prepare a polypropylene anticorrosion material component 1 based on a biomass cytosine flame retardant.

Embodiment 2

[0033](1) Take 0.2 parts of cytosine flame retardant and 92 parts of polypropylene, put them into the internal mixer at 220-230°C and rotate at 120rpm / min to melt and blend for 10-15min, then add 3 parts of antioxidant and 2 parts of toughening agent, blended for 2-3h.

[0034] (2) Then put the material obtained in the above step (1) on a flat vulcanizer to press the plate, and finally extrude it with a twin-screw extruder. The extruded strip is cooled by a water tank and air cooled, and then introduced into a pelletizer for pelletizing and packaging , and then dried in a dryer for 5-8 hours, and finally injection-molded into required test specimens at 215-225°C to prepare a polypropylene anti-corrosion material component 2 based on a biomass cytosine flame retardant.

Embodiment 3

[0036] (1) Take 0.4 parts of cytosine flame retardant and 93 parts of polypropylene, put them into the internal mixer at 220-230°C and 120rpm / min to melt and blend for 10-15min, then add 4 parts of antioxidant and 3 parts of toughening agent, blended for 2-3h.

[0037] (2) Then put the material obtained in the above step (1) on a flat vulcanizer to press the plate, and finally extrude it with a twin-screw extruder. The extruded strip is cooled by a water tank and air cooled, and then introduced into a pelletizer for pelletizing and packaging , and then dried in a dryer for 5-8 hours, and finally injection-molded into required test specimens at 215-225°C to prepare a polypropylene anti-corrosion material component 3 based on a biomass cytosine flame retardant.

Abstract

The invention relates to the technical field of preparation of polypropylene anticorrosive materials, and discloses a polypropylene anti-corrosion material based on a biomass cytosine flame retardant.The polypropylene anti-corrosion material comprises the following raw materials in parts by weight: a cytosine flame retardant, polypropylene, an antioxidant and a flexibilizer, wherein the flexibilizer is a mixture of an ethylene-vinyl acetate copolymer, thermoplastic elastomer and powdered rubber. According to the polypropylene anti-corrosion material based on the biomass cytosine flame retardant, a cytosine derivative, cytidylic acid and tris(epoxypropyl)isocyanurate are subjected to a condensation reaction to generate tri(epoxypropyl)isocyanocytidylic acid, and aluminum hydroxide is addedto react with phosphate groups to generate a salt, so that the biomass cytosine aluminum salt with a flame-retardant effect is achieved. The flame retardant improves integrity of the polypropylene material forming a form of expanded carbon, then carbon on the surface layer of carbon layer is compact, and the inner layer is porous, so that flame-retardant efficiency of the polypropylene material is effectively improved, the adding amount is small, and the flame-retardant effect is good.

Description

technical field [0001] The invention relates to the technical field of preparation of polypropylene anticorrosion materials, in particular to a polypropylene anticorrosion material based on a biomass cytosine flame retardant. Background technique [0002] Polypropylene is a thermoplastic resin prepared by polymerizing propylene. It is a non-toxic, odorless, tasteless milky white high-crystallization polymer. It has good chemical and mechanical properties and high impact resistance. It is easy to process and low in price, and is widely used in plastics, chemicals, packaging, home appliances and other industries. However, polypropylene has disadvantages such as insufficient high temperature resistance strength, flammability and smoke generation, which greatly limits the application range of polypropylene materials. [0003] The intumescent flame retardant system has the advantages of low smoke, low toxicity, and no droplet. Adding an intumescent flame retardant to polypropylen...
