Abstract
The invention discloses a degradable plastic filling masterbatch which is prepared from the following raw materials in parts by weight: 25-40 parts of polyethylene, 60-70 parts of filler, 5-10 parts of a high molecular surface treating agent, 0.01-0.05 part of a hydrolysis resisting agent, 0.1-0.3 part of a hydrophobic modifier and 2-4 parts of a functional assistant, wherein the relative molecular weight of the high molecular surface treating agent is 2000-2500, and the high molecular surface treating agent integrates functions of lubrication, dispersion, coupling and the like; the filler is one of inorganic filler, corn starch and rice bran flour; the hydrolysis resisting agent is a polycarbodiimide UN-03 hydrolysis resisting agent; the functional assistant is one of a toughening agent, an antioxidant, a heat stabilizer, an antistatic agent and an ultraviolet light absorber. The filling masterbatch obtained by the invention has a good filling effect and can improve the biodegradability of plastic products, and the production cost is lowered.
Description
Technical field
The present invention relates to a kind of plastic filler parent granule, be specifically related to a kind of degradable plastics filler parent granule.
Background technology
Because general-purpose plastics can steady in a long-termly exist at nature, hard degradation, therefore its discarded being difficult to afterwards recycles, has caused serious pollution to environment.Biodegradable plastic can comparatively fast be degraded and become one of effective way solving plastic refuse problem of environmental pollution because of it under physical environment.Adopt filler parent granule as the improving one's methods of filling plastic modification, not only can keep the use properties that matrix is good, and can facilitate and add in a large number filler, thereby reach, reduce costs the object of facility processing.But general purpose grade filler parent granule cannot disperse even cannot fill in biodegradable plastic, thereby cause existing general purpose grade filler parent granule cannot be applied to biodegradable plastic.
Summary of the invention
The technical problem solving: for the deficiencies in the prior art, the invention provides a kind of degradable plastics filler parent granule, have good filling effect, can simplify plastic formula and technique, improve plastics degradability, reduce production costs.
Technical scheme: the invention provides a kind of degradable plastics filler parent granule, by forming of the raw material of following mass fraction: polyethylene 25-40 part, filler 60-70 part, macromolecule surface treatment agent 5-10 part, hydrolysis-resisting agent 0.01-0.05 part, hydrophobically modified agent 0.1-0.3 part, functional agent 2-4 part.
Described macromolecule surface treatment agent relative molecular weight is 2000～2500, integrates lubricated, dispersion, coupling etc. multi-functional; Described filler is a kind of in mineral filler, W-Gum, bran powder; Described hydrolysis-resisting agent is polycarbodiimide UN-03 hydrolysis-resisting agent; Described functional agent is a kind of in toughner, oxidation inhibitor, thermo-stabilizer, static inhibitor, UV light absorber.
Beneficial effect: because the present invention has adopted technique scheme, gained filler parent granule has good filling effect, can improve the biodegradable of plastics, reduces production costs.
