Abstract

A degradable polypropylene foamed bead is disclosed and includes a polypropylene matrix and a biodegradation system. The biodegradation system comprises 67-69 parts of polylactic acid, 81-83 parts of polycaprolactone, 15-17 parts of ethoxylated alkylamine, 7.7-7.9 parts of hydroxy polydimethylsiloxane, 8-10 parts of vinyltrimethoxysilane, 3.5-3.7 parts of ammonium polyphosphate, 32-35 parts of nanometer montmorillonite, 9.5-9.7 parts of fumed silica, 2-5 parts of gamma-aminopropyltriethoxysilane, 2.1-2.3 parts of alkylphenol polyoxyethylene, 0.5-0.7 part of an active diluting agent, 0.5-0.7 part of a compatilizer, 1.1-1.3 parts of a coupling agent, 1.5-1.7 parts of a levelling agent and 0.3-0.5 part of mixed rare earth chlorides. Through adding a high-strength system, degradation performance, strength, high-temperature resistance, flame retardance, physical properties and antistatic properties of the polypropylene foamed bead can be improved.

Description

technical field [0001] The invention relates to a production process of a polypropylene foam material, in particular to a degradable polypropylene foam bead and a production process thereof. Background technique [0002] There are isocyanate residues that are harmful to the human body during the foaming process of polyurethane foam, and the foamed material cannot be recycled. However, chlorofluorocarbons or butane are usually used in the foaming process of polystyrene (PS), which has adverse effects on the environment. The product is difficult to degrade and easy to form "white pollution". The United Nations Environmental Protection Organization has decided to stop using PS foam product. Cross-linked polyethylene foam has low rigidity and a maximum service temperature of 80°C. [0003] Compared with the above foam plastics, polypropylene foam material has many advantages: 1) Polypropylene (PP) is more rigid than polyethylene (PE), PP flexural modulus is about 1.52Gpa, PE i...
