Embodiment 1

[0047] A kind of flame-retardant polypropylene material of the present embodiment comprises the following components by weight percentage: 60.7% of polypropylene, 11.7% of 3500 mesh superfine talc powder, 13.2% of brominated flame retardant, antimony trioxide Efficacy agent 5.5%, neutralizing absorbent LDHs 0.8%, rubber 5.1%, antioxidant 0.15%, light stabilizer 2.0%, zinc stearate lubricant 0.05%, antistatic agent 0.8%.

[0048] The polypropylene is a mixture of impact polypropylene, homopolypropylene and high flow polypropylene. Brominated flame retardants are composite flame retardants. The antioxidant is a compound of antioxidant 168 and antioxidant 1010. Among them, antioxidant 1010 is used as the main antioxidant, and antioxidant 168 is used as the auxiliary antioxidant. The light stabilizer is bis(2,2,6,6-tetramethyl-4-piperidinyl) sebacate and 2,2,6,6-tetramethyl-4-piperidinyl stearate compound.

[0049] During the preparation, the raw materials of each component ar...

Embodiment 2

[0051] Referring to Example 1, the difference from Example 1 is that a flame-retardant polypropylene material, by weight percentage, includes the following components: 61% polypropylene, 11.7% 3500 mesh ultrafine talcum powder, brominated flame-retardant Agent 13.2%, antimony trioxide synergist 5.5%, neutralizing absorbent LDHs 0.8%, rubber 4.8%, antioxidant 0.15%, light stabilizer 1.75%, zinc stearate lubricant 0.1%, antistatic agent 1%. The antioxidant is a compound of antioxidant 168 and antioxidant 1790.

Embodiment 3

[0053] Referring to Example 1, the difference from Example 1 is that a flame-retardant polypropylene material, by weight percentage, includes the following components: 60% polypropylene, 11.7% 3500 mesh ultrafine talcum powder, brominated flame-retardant Agent 13.2%, antimony trioxide synergist 5.5%, neutralizing absorbent LDHs 0.8%, rubber 5.3%, antioxidant 0.15%, light stabilizer 2.25%, zinc stearate lubricant 0.1%, antistatic agent 1%.

Abstract

The invention discloses a flame-retardant polypropylene material as well as a preparation method and application thereof, and the flame-retardant polypropylene material comprises the following components in percentage by weight: 60%-65% of polypropylene, 13%-15% of a brominated flame retardant, 5%-7% of an antimony trioxide synergist, 11%-13% of superfine talcum powder, 0.5%-1% of a neutralization absorbent LDHs and the balance of a weather-resistant additive. According to the flame-retardant polypropylene material, the problem of poor weather resistance of a flame-retardant material under the condition of high flame retardant content and harmful smoke of the halogen-containing flame retardant can be solved; and the compatibility among the materials is facilitated, the influence of the flame retardant on the color is reduced, and the material performance is improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a flame-retardant polypropylene material, a preparation method and an application thereof. Background technique [0002] Polypropylene (PP) is divided into isotactic polypropylene, syndiotactic polypropylene and atactic polypropylene according to the position of the methyl group. The molecular weight is about 80,000 to 200,000. It has the advantages of non-toxic, odorless, tasteless, acid and alkali resistance, etc. It is widely used in the fields of household appliances, plastic pipes, high-permeability materials, and mechanical parts. It is one of the plastic varieties with high quality, low price and wide range of uses. Polypropylene has a volume resistivity of 10 15 -10 20 Ω cm, with high insulation, which limits the application of polypropylene in electronics, medical, information and other fields. However, polypropylene is a highly insulating flammable material...
