Abstract

The invention discloses a high-impact-resistance glass fiber reinforced polypropylene material and a manufacturing process thereof, and belongs to the field of polymer modified materials. The high-impact-resistance glass fiber reinforced polypropylene material is a composite material and comprises a modified PP material of a middle main body part and glass fiber gridding cloth glued to the upper face and the lower face of the modified PP material. The modified PP material is prepared from the following components: 5 parts of a polypropylene raw material, 4 parts of glass fiber powder, 0.7 part of butadiene rubber, 0.01 part of a nucleating agent, 0.01-0.02 part of a coupling agent and 0.27-0.28 part of a toughening agent. The glass fiber reinforced polypropylene material with high impact resistance is low in manufacturing cost, has high-strength impact resistance and toughness, can replace traditional tempered glass to intercept objects falling from high altitudes, and effectively prevents the objects falling from high altitudes from hurting people.

Description

technical field [0001] The invention relates to the technical field of polymer modified materials, in particular to a glass fiber reinforced polypropylene material with strong impact resistance and its manufacturing process Background technique [0002] Incidents of falling objects and injuries have occurred frequently in recent years. Experiments have proved that an iron nail with 4 inside can be inserted into the skull when falling from the building, and an empty can can be fatal if thrown from the 25th floor. What's more, a seemingly fragile piece of palm-sized watermelon rind can also cause death if it falls from the 25th floor. [0003] At present, most residential buildings in our country have no awareness of this aspect, and some high-end office buildings, or large markets, will set up a fall-proof floor on the second or third floor in densely populated places, mainly with tempered glass. Composed of glass and steel frame, this structure can solve the problem of fall...
