Abstract
The present invention discloses a kind of degradative plastics formula and preparation method thereof, and each raw material is respectively by weight：PBAT：40 60, starch：10 30, nanomete talc powder：03, Paris white：1 10, plasticizer：17, plasticiser：3 15, antioxidant：0.2 2, peroxide：10‑15；A kind of environmental-friendplastic plastic formula provided by the invention, non-hazardous, plastic tube hardness is high, and elasticity is good, recycled after degrading easy to waste plastic, not only economize on resources, and it is environmentally friendly, meet the environmental protection concept of today's society, and production cost is relatively low, production efficiency is effectively raised, reduces the pollution to environment, reaches energy-saving and environment-friendly purpose.
Description
Technical field
The present invention relates to technical field of novel materials, is a kind of degradative plastics formula and preparation method thereof specifically.
Background technology
Plastics are important organic synthesis high molecular materials, using very extensive, plastic products since 20th century came out,
Have the characteristics that light weight, intensity are high, corrosion-resistant, chemical stability is good, easy to process and both artistic and practical, be widely used in generation
Every field in the range of boundary, but " white pollution " that waste plastic is brought is also increasingly severe, the waste plastic being dropped
Farmland, urban district, Scenic Spot Area, water conservancy projects and both sides of the road are scattered in, to urban environment, health, arable soil, stone
The negative effect that oily resource consumption etc. produces.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of degradable plastic material formula and preparation method thereof, existing modeling is solved
There are the problem of noxious material, environment easy to pollute for material products.
To reach above-mentioned purpose, technological means that the present invention uses for：A kind of degradative plastics formula, each raw material is by weight
Respectively：
PBAT：40-60
Starch：10-30
Nanomete talc powder：0-3
Paris white：1-10
Plasticizer：1-7
Plasticiser：3-15
Antioxidant：0.2-2
Peroxide：10-15.
Further, each raw material is respectively by weight：
PBAT：50
Starch：20
Nanomete talc powder：2
Paris white：5
Plasticizer：3
Plasticiser：8
Antioxidant：1
Peroxide：11.
Further, the starch for fineness be more than 100 general industry starch, including cornstarch, farina,
Starch from sweet potato and tapioca, and modified starch.
Further, the plasticizer is dioctyl phthalate.
The beneficial effects of the present invention are：A kind of environmental-friendplastic plastic formula provided by the invention, non-hazardous, plastic tube hardness
Height, elasticity is good, recycles after degrading easy to waste plastic, not only economizes on resources, and environmental protection, meets the environmental protection of today's society
Theory, and production cost is relatively low, effectively raises production efficiency, reduces the pollution to environment, reaches energy-saving and environment-friendly mesh
's.
Embodiment
In order to make technological means, creation characteristic, workflow, application method reached purpose and effect of the present invention be easy to bright
It is white to understand, below in conjunction with the embodiment of the present invention, the technical solution in the embodiment of the present invention is clearly and completely described.
Embodiment 1：A kind of degradative plastics formula, each raw material are respectively by weight：
PBAT：50

The preparation method of above-mentioned degradation plastic, comprises the following steps：
(1) PBAT, Paris white, plasticizer, peroxide and plasticiser are sequentially added in high-speed mixer
Stirring, is mixed into uniform miscible body, the plasticizer is dioctyl phthalate.
(2) starch, nanomete talc powder, antioxidant are sequentially added in high-speed mixer and stirred, be mixed into uniform miscible
Body, the starch are more than 100 general industry starch, including cornstarch, farina, starch from sweet potato and cassava for fineness
Starch, and modified starch.
(3) the miscible body for obtaining step (1), (2) is added in double screw extruder, is kneaded and is extruded, finally use
Biodegradable plastic particle is made in pelleter.
Obviously, described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.Based on this
Embodiment in invention, the every other reality that those of ordinary skill in the art are obtained without making creative work
Example is applied, belongs to the scope of protection of the invention.
