Embodiment 1

[0039] A modified PP foam reinforcement material is composed of modified PP particles and foam masterbatch, and the mass ratio of the two is 100:4.

[0040] Wherein, each component of the modified PP particles is calculated in parts by mass as follows:

[0041] PP: 50 parts

[0042] Inorganic mineral filler: 30 parts

[0043] Toughener: 16 parts

[0044] Short fiberglass: 5 parts

[0045] Antioxidant 1010: 0.2 parts

[0046] Stearic acid: 0.2 parts.

[0047] Wherein, each component of described foam masterbatch is counted as in parts by mass:

[0048] EVA: 45 parts

[0049] Talc powder: 30 parts

[0050] Azodicarbonamide (AC): 20 parts

[0051] Zinc oxide: 5 parts

[0052] Benzoyl peroxide (BPO): 0.5 parts

[0053] Divinylbenzene: 0.2 parts

[0054] Antioxidant 1010; 0.3 parts.

[0055] The melt index of the PP is 1g / 10min.

[0056] The inorganic mineral filler is composed of talcum powder, montmorillonite and kaolin in a mass ratio of 2:0.5:0.5.

[0057] The tou...

Abstract

The invention belongs to the technical field of macromolecular material modification, and in particular relates to a modified PP (polypropylene) foaming enhanced material and a preparation method thereof. The modified PP foaming enhanced material consists of modified PP particles and foamed masterbatches, wherein the modified PP particles consist of PP, an inorganic mineral filling agent, a toughening agent, short glass fibers, an antioxidant 1010 and a surfactant; and the foamed masterbatches consist of EVA, talcum powder, a foaming agent, a foaming promoter, a crosslinking agent, an assistant crosslinking agent and an antioxidant 1010. The PP is enhanced and modified and then is subjected to chemical foaming, so that the prepared PP foamed material has low density, also has excellent tensile strength, bending strength and impact strength, can be used for replacing parts such as a door plate and an instrument desk on an automobile prepared by non-foamed PP at present, and can achieve the aims of reducing weight, insulating heat, reducing noise and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer material modification, and in particular relates to a modified PP foam reinforcing material and a preparation method thereof. Background technique [0002] Foam plastic has the advantages of light weight, heat insulation, sound insulation, cushioning, and high specific strength. Therefore, it is widely used in the fields of packaging, industry, agriculture, transportation, military industry, aerospace industry and daily necessities. Since the 1990s, the development of foamed plastics in China has been very rapid. The main varieties are polyurethane (PU), soft and rigid foamed plastics, polystyrene (PS) and polyolefin foamed materials. However, PU will produce harmful isocyanate residues during the foaming process and cannot be recycled; while the waste of foamed PS products does not rot and is difficult to recycle, causing "white pollution". In 1991, the European Community formulated a mandatory ...
