Description

technical field

[0001] The present invention relates to a kind of composition used for preparing glass fiber reinforced polypropylene material and its prepared material and application, in particular to a kind of composition used for preparing glass fiber reinforced polypropylene material, which is prepared from the composition Glass fiber reinforced polypropylene, glass fiber reinforced polypropylene foam profiles and their applications. Background technique

[0002] In recent years, because polypropylene has good mechanical properties, chemical stability and low price, its glass fiber reinforced and modified products are widely used in automobiles, home appliances, furniture and other industries. However, polypropylene is a non-polar highly crystalline polymer, which has poor compatibility with glass fibers, resulting in poor toughness of products, large molding shrinkage, and floating fibers on the surface. At present, silane coupling agents are mainly used to modify the...
