Abstract

The invention discloses a low-emission high-performance long glass fiber reinforced PP composite and a preparation method thereof. Magnesium chlorate, potassium nitrate and propylene glycol are selected and synergistically interacted, the emission of the long glass fiber reinforced PP composite is effectively reduced, micromolecules of a product prepared from the long glass fiber reinforced PP composite are not prone to emitting due to the luminous effect and thermal effect, the stability of the composite is maintained, and meanwhile the mechanical property of the prepared PP composite can be effectively maintained. The PP composite has the excellent impact resistant property and low-emission property, the surface is smooth and free of floating fiber, and the PP composite is specially suitable for preparing products such as automobile parts, electronic product elements, instrument parts and aeronautical equipment parts.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a low-emission, high-performance long glass fiber reinforced PP composite material and a preparation method thereof. Background technique [0002] Long glass fiber reinforced PP composite materials have the characteristics of light weight, high strength, good impact resistance, and good dimensional stability. They can be used to replace traditional reinforced engineering plastics and even metal materials such as steel in practical applications. In recent years, with the progress of automobile lightweight, long glass fiber reinforced PP composite materials are more and more widely used in the automobile industry as the main material for replacing steel with plastic due to their cost-effective advantages. Long glass fiber reinforced polypropylene materials are used The performance of making auto parts is equivalent to that of steel parts, but the weight is reduced by 40% or more,...
