Biodegradation expanded plastic and method for manufacturing same

摘要: The invention relates to a biological degradation foamed plastic which comprises the following components and contents: polylactic acid resin: 100 portions; plasticizer: 10 20 polyhydroxy alkanoates multipolymer: 50 corn starch: 60 foaming agent: 8 17 blowing promoter: 2 4 lubricant: 0.8 1.2 antiager: 0.45 0.70 portion, amount is calculated by weight. of also provides manufacturing method for plastic. characterized low density, high specific strength, good shock absorption performance complete degradation, can be applied not only in packages industrial products, such as domestic appliances, electron, instruments, fittings glass/ceramic etc., but field that needs heat preservation thermal insulation, thus new environmental-friendly packaging material.
