Glass fiber reinforced polycarbonate composite material with flame-retarding mobility and thermal endurance, and product thereof

Abstract

The invention belongs to the technical field of high polymer material, and particularly relates to a glass fiber reinforced polycarbonate composite material with flame-retarding mobility and thermal endurance, and a product thereof. The composite material is prepared from, by weight, 100 parts of polycarbonate resin, 20-150 parts of glass fiber, 2-30 parts of flame retardant, and 2-10 parts of lubricant. Through adding a certain amount of glass fiber, flame retardant and lubricant in the polycarbonate resin, the glass fiber reinforced polycarbonate composite material with flame-retarding mobility and thermal endurance, and the product thereof can acquire composite materials and products with high flame retarding grade; the flame retarding grade can reach 0.5 mmV-O grade; besides, the composite material has excellent mobility and thermal endurance.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of polymer materials, and in particular relates to a glass fiber reinforced polycarbonate composite material with controllable flame-retardant fluidity and temperature resistance and a product thereof. [0003] 【Background technique】 [0004] With the development of the times, the shells of handheld consumer electronics have gradually shown a trend of diversification from a single plastic shell. In recent years, industries such as computers and tablets have developed towards lighter and thinner products. Polycarbonate (PC) and glass fiber (referred to as glass fiber, GF) are used more and more in structural parts, especially polycarbonate composite materials with high glass fiber content. [0005] Due to the limitations of painting, thin parts or long-term use environment, polycarbonate composite materials must have high fluidity, high temperature resistance and high flame retardancy. However, glass...

AI Technical Summary

Problems solved by technology

[0005] Due to the limitations of painting, thin parts or long-term use environment, polycarbonate composite materials must have high fluidity, high temperature resistance and high flame retardancy. However, glass fiber reinforced polycarbonate composite materials, there is a wick Effect, that is, although the polycarbonate resin itself is not easy to burn, it is affected by the glass fiber, which causes local high temperature to generate ignition, and then forms a large area of ​​combustion, and the higher the glass fiber content, the more serious the wick effect, and it is difficult to reach below 0.8mm The thickness of the V-0 grade, and even if it reaches a high flame-retardant grade, the fluidity and temperature resistance of the composite material cannot be balanced. In the prior art, the fluidity of the composite material is good, and the temperature resistance is poor, and vice versa. If the temperature is good, the fluidity is poor, and the two are not equal to the ideal state of being excellent at the same time

[0006] In view of this, it is necessary to develop a glass fiber reinforced polycarbonate composite material and its products with controllable flame retardancy, fluidity and temperature resistance to solve the above problems of uncontrollable flame retardancy, fluidity and temperature resistance. question
