Abstract
The invention discloses PBS-based degradable plastic, which is characterized by including the following components, by weight, 50-80 parts of a master batch, 40-80 parts of modified starch, 1-3 parts of a pigment and 2-4 parts of an additive. The master batch is PBS plastic. The additive includes the following components, by weight, 10-15 parts of a lubricant, 20-40 parts of a plasticizing agent and 5-10 parts of an anti-oxygen agent. The lubricant is one selected from barium stearate, fatty acid amide and monoglyceryl stearate. The plasticizing agent is one selected from DEHP, DOP and DBP. The anti-oxygen agent is an anti-oxygen agent 1010 or an anti-oxygen agent TNP. The PBS-based degradable plastic has both strong mechanical property and excellent stability, is not liable to generate harmful substances during use, and can be widely used in the fields of food package and living.
Description
Technical field
The present invention relates to a kind of PBS base degradable plastic.
Background technology
Degradable plastics refers to and adds some auxiliary agents promoting it to degrade in the plastic or adopt reproducible natural matter to manufacture, application performance requirement can be met in use and preservation period, and after using under certain environmental conditions, within a short period of time can there is considerable change in its chemical structure, and cause some character to lose, or during synthesis, just there are class plastics of degradation property.Degradable plastics has very important effect in the white pollution problems solving globalization.
Degradable plastics is as multifunctional novel technologic material, and range of application is wide, and market potential is very big.According to pertinent data display, the consumption of biological degradation polyalcohol in 2000 accounts for about 2% of plastics total amount consumed, and consumption reaches about 4,000,000 ~ 5,000,000 t.The U.S. reaches 900,000 t in 2000, and Novon company of the U.S. has established the starch base polymeric material factory of 4.5 ten thousand t/a; Japan's degradative plastics actual market scale in 2000 reaches 200,000 t, and Japanese Showa Polymer Company has established the saturated alkyl system in polyester production of 500t/a.
Domestic also have tens of enterprises to plan to build or built starch base or natural fiber base (comprising paper pulp) production line, as: Changchun establishes sino-america joint-venture enterprise, produces 6000t starch-based material per year; Wuhan, Hubei " green " group plans to build joint venture, produces the mess-tin (tool) of sweet potato starch base; Shanghai Shi Run industrial corporation invests millions of unit and is building fiber base mess-tin factory based on bagasse; Granary, Jiangsu is big to be reached (in newly joint) corporate investment 1,000 ten thousand yuan, built fiber base production line; It is the production line of main raw material that spark development area, Shanghai spark papermaking company builds with paper pulp, produces 20,000 disposable tablewares daily; Shanghai Li Jun composite table-ware factory invests 3,000,000 yuan, the production equipment that to build with flour product factory pin material be raw material production disposable tableware.
Current degradable plastics Problems existing is mainly expensive, and be difficult to utilization and extention, starch-filled plastic falls and do not understand, and biodegradable plastic aftertreatment needs comprehensive compost construction; In addition, degradable plastics self-technique as more reasonably technical recipe, accurately controlled degradation, need to improve further with rear fast degradation, the thoroughly recovery and utilization technology etc. of degradation property and scrap stock and perfect.The definition that degraded by environment polymer is still ununified so far in the world and set up unified Test model synthetic techniques, identifier and Product checking standard completely, causes its technical market, produce market more chaotic.In addition, the current research of degradable plastics is degraded to master still with fluoropolymer resin, and majority fails the factor of auxiliary agent to take into account; Except complete biodegradable plastics, the middle degraded product impact on animal, plant of all the other various degradable plasticss in degradation process not yet can be evaluated etc.
Summary of the invention
The object of this invention is to provide a kind of mechanical property good, the strong and plastic material of easily degraded of stability.
The present invention is achieved through the following technical solutions:
A kind of PBS base degradable plastic, is characterized in that, comprise following component by weight: masterbatch 50-80 part; Treated starch 40-80 part; Pigment 1-3 part; Auxiliary agent 2-4 part.
Described masterbatch is PBS plastics.
Described auxiliary agent comprises following component by weight: lubricant 10-15 part; Softening agent 20-40 part; Oxidation inhibitor 5-10 part.
