Problems solved by technology

However, the polypropylene oxygen index is low, only 17.4, and it is easy to burn, and the traditional flame-retardant polypropylene is brittle after adding a large amount of flame retardants, and cannot have high flame-retardant properties and better performance at the same time. Mechanical properties, and the weather resistance of polypropylene is poor, so it is not suitable for making outdoor communication cabinets

Abstract

The invention discloses a polypropylene composition for an outdoor communication cabinet. The polypropylene composition comprises the following components in part by weight: 100 parts of polypropylene, 0.5 to 20 parts of compatilizer, 1 to 30 parts of toughening agent, 5 to 40 parts of flame retardant, 0.5 to 20 parts of flame retardant synergist, 0.1 to 2 parts of antifogging agent, 1 to 50 parts of dimensional stabilizer and 0.05 to 5 parts of ultraviolet absorber. The polypropylene composition for the outdoor communication cabinet has higher flame retardancy, mechanical properties and weather resistance.

Description

【Technical field】 [0001] The invention relates to a polymer material, in particular to a polypropylene composition for an outdoor communication cabinet. 【Background technique】 [0002] Traditional outdoor communication cabinets are mainly made of metal, which is heavy in weight, complex in processing technology, and high in processing cost. Polypropylene has the advantages of low density, high hardness, and easy processing, so it is widely used in various fields. However, the polypropylene oxygen index is low, only 17.4, and it is easy to burn, and the traditional flame-retardant polypropylene is brittle after adding a large amount of flame retardants, and cannot have high flame-retardant properties and better performance at the same time. Mechanical properties, and the weather resistance of polypropylene is poor, so it is not suitable for the manufacture of outdoor communication cabinets. 【Content of invention】 [0003] In view of the above situation, it is necessary to...
