Problems solved by technology

[0003] Halogen-based flame retardants are usually added to traditional flame-retardant polypropylene materials, but the gas produced during the combustion process is harmful to the human body and causes serious environmental pollution, which does not meet environmental protection requirements
Therefore, the requirements for halogen-free flame-retardant polypropylene materials are increasing day by day. However, the amount of halogen-free flame retardants added to polypropylene materials is large, which has a great impact on the overall performance of the product. It is difficult to meet the flame-retardant requirements. Performance conditions, while maintaining the rigidity and toughness of the product at an optimal level
[0004] With the aging of China's population and people's high-end demand for bathrooms, smart toilets, as a growing daily necessities, are increasingly appearing in people's daily lives. Non-toxic polypropylene, which requires polypropylene materials to have excellent flame retardancy and scratch resistance, while ordinary flame retardant formulations generally cannot achieve excellent scratch resistance; at the same time, based on hygiene requirements, the antibacterial properties of toilet seats are becoming more and more popular. Pay attention to
[0005] The existing technology for the modification of polypropylene has made some progress in flame retardancy, scratch resistance, and antibacterial properties, but all of them are mainly researched and developed in a single technical field, and at the same time solve the flame retardancy, scratch resistance, and antibacterial properties. still have difficulties
[0006] CN109575430A discloses a halogen-free flame-retardant polypropylene material, which adds zirconium phosphate and expanded graphite to the formula to achieve a synergistic flame-retardant effect, but the expansion-type flame retardant added in the formula reaches 10-20 parts, and the flame retardant The overall addition is still more

[0053] Preparation of Zirconium Phosphonate 1#

[0054] Accurately weigh 20.3g of zirconium oxychloride and dissolve it in 200mL of deionized water to make an aqueous solution of zirconium oxychloride, and accurately weigh 21g of glyphosate and dissolve it in 3000mL of deionized water to make an aqueous solution of glyphosate. Add 40 g of hydrofluoric acid with a concentration of 40% to the zirconium oxychloride aqueous solution, stir and mix the zirconium oxychloride aqueous solution and the glyphosate aqueous solution in a flask, keep stirring, heat the reaction in a water bath at 80° C. for 6 hours, centrifuge the product, and use Wash with deionized water until the supernatant is neutral, dry at 90°C, and grind the sample into powder to obtain 28.7 g of zirconium glyphosate phosphonate, which is denoted as ZrGP1, and its X-ray diffraction (XRD) spectrum is shown in figure 1 , the scanning electron microscope (SEM) photo see figure 2 .

Abstract

The invention discloses a halogen-free flame-retardant scratch-resistant antibacterial polypropylene material as well as a preparation method and application thereof. The halogen-free flame-retardantscratch-resistant antibacterial polypropylene material is prepared from the following raw materials in parts by weight: 76-89 parts of polypropylene; 4-10 parts of an intumescent flame retardant; 2-12parts of silver ammonium phosphomolybdate intercalation modified zirconium phosphonate; 1-5 parts of ceramic fiber powder; 0.5-4 parts of silicone master batch; 0.3-1 part of an antioxidant; and 0.2-1 part of white oil. The silver ammonium phosphomolybdate intercalation modified zirconium phosphonate, the ceramic fiber powder and the silicone master batch are added at the same time, so that the compatibility with polypropylene can be greatly improved, the flame retardant property of the material is improved, the addition amount of a flame retardant is greatly reduced, the scratch resistance of the material can be improved, the material has excellent antibacterial property, and the material has excellent comprehensive performance when applied to the field of intelligent toilet lids.

Description

technical field [0001] The invention relates to a modified polypropylene material and a preparation method thereof, in particular to a halogen-free flame-retardant, scratch-resistant, antibacterial polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene material is one of the four general-purpose plastics. It can be modified by toughening, strengthening, filling, blending and other modification methods to obtain modified materials with excellent comprehensive properties. It has been widely used in the fields of automobiles, home appliances, and building materials. Among them, the filling modification of polypropylene, on the one hand, can reduce the cost, and on the other hand, it can improve the performance of polypropylene composite materials. [0003] Halogen-based flame retardants are usually added to traditional flame-retardant polypropylene materials, but the gases produced during the combustion process are harmful to the hu...
