Abstract
The invention discloses a kind of functional filled-type light degradation master batches and its preparation method and application.A kind of functional filled-type light degradation master batch of the present invention, is made of inorganic powder, photodegradable aid, surfactant, processing aid and resin, and the weight ratio of each component is inorganic powder：Photodegradable aid：Surfactant：Processing aid：Resin=60-80：2-10：1-4：2-6：10-20.The present invention uses the inorganic material filled-type technology of micro/nano level, it is at low cost, due to using superfine function inorganic powder, the degradation rate and controllability of film can be improved, in the case of larger filling proportion, the mechanical property of film is not influenced or had little effect on, and the brightness and flexibility of film can be improved.It is more friendly to environment it to be prepared membrane product using the master batch of the present invention, white pollution problems can be greatly reduced.
Description
Technical field
The present invention relates to a kind of plastics membrane-based article raw material and preparation method thereof, more particularly to a kind of functional filled-type light
Degradative plastics membrane-based article raw material and its preparation method and application.The invention belongs to plastics membrane-based article processing technique fields.
Background technology
Plastics membrane-based article is widely used to agricultural, industry and various fields of recent life, it has also become irreplaceable product.
But plastic products are widely used, and serious white pollution is caused to environment, have influenced life and the health of the mankind.Therefore
Solving pollution problem caused by plastic product becomes very urgent.
Being presently used for solution white pollution, there are mainly two types of approach：One is biodegradation, another kind is light degradation.Before
For person because of high cost, performance is poor, therefore is dfficult to apply in the degradation of plastic foil.Light degradation is currently used for plastic foil, spy
It is not a kind of using relatively broad method of disposable PE membrane degradations.
The present invention proposes a kind of functional filled-type light degradation master batch and preparation method thereof, the present invention with it is existing other
Technology is compared, and sharpest edges are the inorganic material filled-type technology using micro/nano level, at low cost, due to using superfine function
Property inorganic powder, can be improved the degradation rate and controllability of film, in the case of larger filling proportion, does not influence or have little effect on
The mechanical property of film, and the brightness and flexibility of film can be improved.
Invention content
Technical problem to be solved by the invention is to provide a kind of photodegradable functional filled-type master batch and its preparations
Method.
In order to achieve the above object, present invention employs following technological means：
A kind of functional filled-type light degradation master batch of the present invention, by inorganic powder, photodegradable aid, surfactant, adds
Work auxiliary agent is formed with resin, and the weight ratio of each component is inorganic powder：Photodegradable aid：Surfactant：Processing aid：Resin=
60-80：2-10：1-4：2-6：10-20.
In the present invention, it is preferred to, the inorganic powder is selected from blanc fixe, calcinated talc powder, calcined kaolin, carbon
The grain size of the mixture that one or more of sour calcium is compounded according to arbitrary proportion, the inorganic powder is 3000-10000
Mesh.
In the present invention, it is preferred to, the photodegradable aid be selected from dodecyl ferrocene, ferric stearate, calcium stearate,
The mixture that one or more of magnesium stearate, zinc stearate are compounded according to arbitrary proportion.
In the present invention, it is preferred to, the surfactant is selected from stearic acid, titanate coupling agent, Aluminate coupling
The mixture that one or more of agent, silane coupling agent and polymer coupler are compounded according to arbitrary proportion.
In the present invention, it is preferred to, the processing aid is selected from White Mineral Oil, paraffin, PE waxes (polyethylene wax), EBS (second
Alkenyl bis-stearamides), PP waxes (polypropylene wax), one or more of oxidic polyethylene is according to arbitrary proportion compounding
Mixture.
In the present invention, it is preferred to, the resin is selected from HDPE (high density polyethylene (HDPE)), (low-density high-pressure is poly- by LDPE
Ethylene), LLDPE (linear low density polyethylene), EVA (ethylene-vinyl acetate copolymer), POE (polyolefin plastomers), POP
The mixture that one or more of (polyolefin elastomer) is compounded according to arbitrary proportion.
Further, the invention also provides the method for preparing the functional filled-type light degradation master batch, according to
Any one progress in lower two methods：
First method：Weight ratio described in accordance with the claim 1 weighs each raw material, and by inorganic powder, surfactant adds
Enter high-speed stirred in homogenizer, high-speed stirred is added together when temperature of charge rises to 90-100 DEG C, then by remaining raw material
In machine, continue high-speed stirred, when temperature of charge rises to 120-125 DEG C can blowing, pending good material is cooled to 40 DEG C
Hereinafter, with parallel double-screw extruder in 140-170 DEG C of extruding pelletization, the functional filled-type light degradation master batch is obtained；
Second method：Weight ratio described in accordance with the claim 1 weighs each raw material, and mixing is added in all raw materials together
It plasticates in machine, plasticate 15-20min, and when temperature of charge rises to 150-180 DEG C, material can go out in melting dough
Material is transferred in double wrist forced feed machines by material while hot, with cone single screw extruder at 140-170 DEG C extruding pelletization,
Obtain the functional filled-type light degradation master batch.
Further, the invention also provides the functional filled-type light degradation master batches to prepare plastics membrane-based article
In application, it is preferred that the plastics membrane-based article include agricultural mulching, house refuse bag, life packaging bag, express delivery use
