Problems solved by technology

[0003] Polypropylene resin is generally blended with polypropylene resin and mineral filler masterbatch in the manufacturing process. Due to problems such as dispersion compatibility, it is difficult to balance the rigidity and toughness of polypropylene resin, and the impact strength of polypropylene resin is relatively low. Low and poor MD tear properties with inconsistent shrinkage

Embodiment Construction

[0018] Embodiments of the present invention are described in detail below. No specific techniques or conditions are indicated in the examples, and the techniques or conditions described in the literature in this field or the product specification are carried out. The reagents or instruments used were not indicated by the manufacturer, and they were all commercially available conventional products.

[0019] Implementation column 1

[0020] A kind of rigid polypropylene resin material, it is made up of the raw material of following mass parts:

[0021] 80% of polypropylene resin, 12.9% of stiffening agent, 2% of compatibilizer, 0.1% of antioxidant, and 5% of nucleating agent. Wherein the ratio of the polypropylene pellets to the polypropylene powder is 10.

[0022] Among the above components, the polypropylene resin is homopolypropylene, the compatibilizer is hydrogenated styrene-butadiene block copolymer, and the antioxidant is tetrakis [3-( 3,5-di-tert-butyl-4-hydroxypheny...

Abstract

A stiffened polypropylene resin material is prepared from, by mass, 75-85% of polypropylene resin, 10-20% of a stiffening agent, 1-3% of a compatilizer, 0.1-0.5% of an antioxidant and 3-5% of a nucleating agent. The raw material of the polypropylene resin is a mixture of a powder and a granule, and the stiffening agent is added, so that the stiffness and the toughness of the polypropylene resin can be considered, the impact strength and the longitudinal tearing property of the polypropylene resin can be improved, and the shrinkage rate is stable.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a reinforced polypropylene resin material. Background technique [0002] Polypropylene resin material has the advantages of non-toxic, odorless and low density, and its strength, stiffness, hardness and heat resistance are all better than low-pressure polyethylene, and can be used at about 100 °C. At the same time, the polypropylene resin material has good dielectric properties and high-frequency insulation and is not affected by humidity. [0003] Polypropylene resin is generally blended with polypropylene resin and mineral filler masterbatch in the manufacturing process. Due to problems such as dispersion compatibility, it is difficult to balance the rigidity and toughness of polypropylene resin, and the impact strength of polypropylene resin is relatively low. Low and poor longitudinal tear properties, while shrinkage is not stable. [0004] Therefore, it is necessary to p...
