Precipitation-resistant halogen-free flame-retardant reinforced nylon material and preparation method thereof

Abstract

The invention relates to a precipitation-resistant halogen-free flame-retardant reinforced nylon material and a preparation method thereof. The material provided by the invention comprises the following components in parts by weight: 30-55 parts of nylon, 25-40 parts of glass fiber, 5-10 parts of modified melamine cyanurate, 0.5-3 parts of a compatilizer, 10-25 parts of a flame-retardant toughening agent and 1-3 parts of other auxiliaries. According to the invention, the surface modified melamine cyanurate is adopted to enhance nylon, the nylon has excellent compatibility and is compounded with the flame-retardant toughening agent with flame-retardant elements, so that low precipitation and low corrosion of the halogen-free flame retardant and high electrical performance of the flame-retardant enhanced nylon material are realized on the premise of keeping good mechanical properties, heat resistance and the like. Due to the adoption of the flame-retardant toughening agent, the use of a traditional flame retardant is greatly reduced, and the mechanical property of the material is powerfully improved. Meanwhile, the product has the characteristics of environmental protection, high dimensional stability and the like, and meets the key material requirements of products such as household appliances and new energy automobiles.

Description

technical field [0001] The invention relates to a home appliance material and a preparation method thereof, in particular to a precipitation-resistant halogen-free flame-retardant reinforced nylon material and a preparation method thereof, belonging to the field of material technology. Background technique [0002] Many key components of home appliances are made of flame-retardant nylon materials. With the more sophisticated product design, the requirements for safety, heat resistance, electrode corrosion, and precipitation of flame-retardant nylon materials are also continuously improved; at the same time, it is easier to meet the requirements for the processability of forming thin-walled products. Compared with halogen-based flame retardants, halogen-free flame-retardant modified nylon materials have higher CTI values ​​and lower toxicity, and have gradually become the mainstream of flame-retardant nylon materials for home appliances. Although the material is widely used,...

AI Technical Summary

Problems solved by technology

Although the material is widely used, there are still many specific problems in the process of use, such as: 1. The current halogen-free flame-retardant nylon materials for household appliances are mainly red phosphorus flame-retardant reinforced nylon, because of its compatibility with the nylon system. Poor capacity, flame retardant nylon material has very poor toughness, lack of toughness and elasticity, etc. 2. Red phosphorus flame retardant has poor resistance to humidity and heat, surface migration resistance, easy to precipitate, sweating, forming phosphoric acid, corroding electrodes or components , causing harm to the electrical performance of the product
