Abstract
The invention discloses a biodegradable plastic. The biodegradable plastic comprises the following components in parts by mass: 30 parts of acrylic resin, 45-60 parts of plant fiber starch, 10-15 parts of compound protein, 3 parts of compatilizer, 0.5 part of flexibilizer, 0.01 part of modifier, 1 part of polymer chelating agent and 8 parts of degradation accelerant. Through adding the plant fiber starch in the acrylic resin, and adding the polymer chelating agent and the degradation accelerant in a preparation process, the plastic is biodegradable, the environment is protected, the application of the plastic is expanded, and therefore the biodegradable plastic has wide practicability.
Description
Technical field
The present invention relates to a kind of biodegradable plastic, belong to the macromolecule chemical industry technical field.
Background technology
Plastics because its quality is light, intensity is high, stable chemical performance and the advantage such as cheap broad development in a lot of fields.Plastics industry is very fast, and still there is no appropriate treatment process with the plastics of crossing, and plastic garbage just brings serious pollution to physical environment.Secondly non-degradative plastics is that high density polyethylene(HDPE) (HDPE), polypropylene (PP), polystyrene (PS) and polyvinyl chloride (PVC) development generate by Low Density Polyethylene (LDPE) and linear low density polyethylene (LLDPE) mostly.And these plastics are generally all finally disposed as solid waste, cause in air pollutents such as forming acid rain, our life is worked the mischief.
Summary of the invention
Goal of the invention: the object of the invention is to for the deficiencies in the prior art, a kind of protection of the environment is provided, adapts to social development, practical biodegradable plastic.
Technical scheme: a kind of biodegradable plastic of the present invention, the parts by weight of its component are:
Acrylic resin: 30 parts;
Plant fiber starch: 45 ~ 60 parts;
Complex proteins: 10 ~ 15 parts;
Compatilizer: 3 parts;
Toughner: 0.5 part;
Properties-correcting agent: 0.01 part;
Polymer integrated agent: 1 part;
Degradation of promoter: 8 parts.
Described compatilizer is modified by maleic acid anhydride graft HDPE multipolymer.
Described toughner is acrylonitrile-butadiene-styrene copolymer.
Described properties-correcting agent is cellulosetri-acetate fat.
Described polymer integrated agent is amido silicon oil.
Beneficial effect: a kind of biodegradable plastic provided by the invention; by add plant fiber starch in acrylic resin; and in preparation process; increase polymer integrated agent and degradation of promoter; make plastics biodegradable; protection of the environment, the application of expansion plastics, have practicality widely.
