Abstract
The invention relates to a production process of an anti-blocking master batch, and belongs to the technical field of polyethylene additives. The production process of the anti-blocking master batch comprises the following steps: adding polyethylene and hydrated magnesium silicate into a stirring machine through a feeding machine, mixing for 2-4 minutes, subsequently adding erucyl amide into the stirring machine, continuously mixing for 4-6 minutes, and standing for 1.5-2.5 hours so as to obtain a standby substance; and adding the standby substance into a twin-screw extruder, sufficiently fusing at 50-110 DEG C, extruding, chopping by using a chopping machine, cooling with water, and dehydrating, thereby obtaining the anti-blocking master batch. The production process provided by the invention has the characteristics of low production cost and small raw material addition amount, and is environment-friendly and sanitary, low in working intensity, and applicable to development requirements of a production additive on environmental friendliness, simplicity and multiple functions, and the service lives of a grinding head, a cutter and a screw of production equipment can be prolonged.
Description
Technical field
The present invention relates to the production technology of a kind of tissue adhesion masterbatch, belong to polyethylene additive technology field.
Background technology
Polyolefin film is widely used in industrial goods and the aspect such as the packaging of daily necessities and agricultural production, but polyolefin is thin
Film has one " adhesion " phenomenon, makes troubles during using polyolefin film to people.Existing in order to solve the adhesion of thin film
As, people can add antiblocking agent or slipping agent in the manufacture process of polyolefin film.Slipping agent generally refers to fatty acid acyl amine,
Such as oleamide, erucyl amide etc., this compounds can gradually surface from polyolefin film internal migration to polyolefin film,
The surface of film forms a tunic, and this tunic can reduce the coefficient of friction between thin film, makes thin film be prone to interformational sliding, improves its opening
Property.Simultaneously because aliphatic amide compounds has certain polarity, film surface hygroscopicity can be changed, thus play anti-quiet
The effect of electricity, weakens the Electrostatic Absorption between thin film, improves the resistance to blocking of thin film equally.Existing tissue adhesion masterbatch product is single,
Production cost is high, and easily equipment is caused damage in production process, therefore, it is necessary to further ground tissue adhesion masterbatch
Study carefully.
Summary of the invention
It is an object of the invention to provide the production technology of a kind of tissue adhesion masterbatch, have that production cost is low, environmentally-friendly sanitary, work strong
Spend feature low, that product is compound,
The production technology of tissue adhesion masterbatch of the present invention, comprises the following steps:
(1) mixing
Polyethylene and hydrated magnesium silicate are joined stirrer for mixing 2-4min through screw(-type) feeder, then erucyl amide is added
In blender, continue mixing 4-6min, after standing 1.5-2.5h, obtain spares；
(2) pelletize
Spares is joined in double screw extruder, fully extrudes after fusion at 50-110 DEG C, then through pelleter pelletizing,
After water cooling, dehydration, obtain tissue adhesion masterbatch.
Wherein, mass percent shared by polyethylene in tissue adhesion masterbatch, hydrated magnesium silicate and erucyl amide is: polyethylene 50-60%,
Hydrated magnesium silicate 20-40%, erucyl amide 10-20%.
The concrete operation step of the present invention is as follows:
1, mixing
(1) according to the good various raw materials of recipe requirements accurate weighing, stand-by；
(2) fume recovery system is opened；
(3) open height and stir machine, and polyethylene and hydrated magnesium silicate are sufficiently mixed 2-4min through screw(-type) feeder addition high mixer；
(4) erucyl amide is added high mixer through screw(-type) feeder；
(5) after being sufficiently mixed 4-6min, material is put into hopper, standby after standing two hours；
2, pelletize
(1) granulating system each temperature controlled region temperature, from 1st district to 11 district's temperature from low to high, low temperature 50 DEG C, high temperature 110 DEG C are set；
(2) opening comminutor temperature control system, Dai Ge district temperature rises to design temperature, constant temperature 2 hours；
(3) material is added parallel dual-screw feeding machine；
(4) open water cooling, pelleter, dewaterer successively, blow machine；
(5) comminutor main frame is opened, and adjust rotating speed to 300r/min；
(6) parallel dual-screw feeding machine is opened, adjustment rotating speed to 500r/min；
(7) material is extruded after double screw extruder fully fuses, after pelleter pelletizing, water cooled but, give through blowing machine after dehydration
Enter feed bin.
Beneficial effects of the present invention is as follows:
The production technology of the present invention has the advantages that production cost is low, raw material addition is few, and can extend production equipment bistrique,
Cutting knife and the service life of screw rod, environmentally-friendly sanitary, labor strength are low simultaneously, adapt to produce auxiliary agent environmental protection brief multi-functional
Demand for development.
