Problems solved by technology

However, the properties of flame-retardant plastics currently used cannot meet the requirements, and halogen flame retardants are often used, which will release hydrogen halide during combustion and cause serious harm to the human body.
For example: Chinese patent 201110226496 discloses a flame retardant plastic formula; 201210088509 discloses a flame retardant plastic; 201210484784 discloses a halogen-free flame retardant modified plastic; the properties of the flame retardant plastics disclosed in these 3 patents are not very good , so the performance of the existing flame-retardant plastics still cannot meet people's requirements

The plastic disclosed by the invention has the characteristics of high notch impact strength, high bending strength, high hardness, favorable flame retardancy, favorable aging resistance and the like; and the method disclosed by the invention is simple in technique and convenient for large-scale production.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an anti-aging flame-retardant plastic and a preparation method thereof. technical background [0002] Plastic material is a material with good performance. Because plastic has the advantages of light weight, no rust, and good insulation, it is used in many aspects of the production of many products. Plastics are easy to process, have good dimensional stability and surface gloss, are easy to paint and color, and are widely used in more and more fields. However, the quality of plastics on the market is not stable, the anti-aging performance is not good, and they are still prone to aging, cracking, and reduced service life. Some plastics with better effects are made through complicated processes, but the product cost is high. For example, Chinese patent 201010273202 discloses aging-resistant environmentally friendly plastics. The bending strength and hardness of the pla...
