Abstract
The present invention relates to plastic production technology field, more particularly to a kind of strap production technology, and wire drawing grade polypropylene, COPP are mixed in proportion into stirring 8 minutes；Toughener and metallocene PE are proportionally added, remixes uniform stirring 4 minutes；It is proportionally added into color masterbatch and is well mixed stirring 2 minutes；Hopper will be pumped into according to the deployed dispensing of aforesaid operations, and be heated up to 80 degrees Celsius, 0.2 MPa of pressure in hopper；And in process of production, defoamer is at the uniform velocity added by proportioning from secondary hopper with small screw.Using strap made from the technique of the present invention, it has high tenacity, high tolerance, and low using the production cost of the technique.
Description
Technical field
The present invention relates to plastic production technology technical field, more particularly to a kind of strap production technology.
Background technology
Polypropylene with excellent mechanical property by plastic processing industry practitioner due to being paid much attention to.It is poly-
The major advantage of propylene is that density is low, and intensity is high, good toughness, and heat distortion temperature is high, thus is widely applied to strap
In preparation.Existing strap, toughness deficiency, it can not preferably meet to produce needs, it is impossible to effectively protect product.
The content of the invention
To solve above-mentioned problem, the present invention provides a kind of strap production technology, has obtained strap
High tenacity, high tolerance and it is inexpensive the features such as.
A kind of strap production technology, including wire drawing grade polypropylene 50-70%, COPP 17.5-27.5%, increase
Tough dose of 0.3-0.8%, metallocene PE 10.5-20.5%, color masterbatch 0.3-0.8% and defoamer 0.5-1.5%；The increasing
Thick dose is POE；
The technological process of described strap formula is specific as follows：
S1, dispensing：Wire drawing grade polypropylene, COPP are mixed in proportion into stirring 8 minutes；Proportionally plus
Enter toughener and metallocene PE, remix uniform stirring 4 minutes；It is proportionally added into color masterbatch and well mixed 2 points of stirring
Clock；
S2, by according to the hopper that is pumped into of dispensing deployed S1, and be heated up to 80 degrees Celsius, pressure 0.2 million in hopper
Pa；And in process of production, defoamer is at the uniform velocity added by proportioning from secondary hopper with small screw.
Preferably, the preferred formulations scheme of the strap is：Wire drawing grade polypropylene 60%, COPP 22.5%,
Toughener 0.5%, metallocene PE 15.5%, color masterbatch 0.5%, defoamer 1%.
Beneficial effects of the present invention are：Preparation technology is simple, and can preferably improve toughness and tolerance, reduces simultaneously
Production cost.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to this hair
It is bright to be further elaborated.It should be appreciated that specific embodiment described herein and does not have to only to explain the present invention

The strap material fit postorder production equipment of bright technique productions, can be made high tenacity, the strap of high tolerance.
In the present invention, specific embodiment 3：
Dispensing：By wire drawing grade polypropylene 70%, COPP 17.5%, stirring 8 minutes is well mixed；Add
0.8% toughener POE and 11% metallocene PE, after being well mixed stirring 4 minutes；Add 0.3% color masterbatch and mix
Close uniform stirring 2 minutes；
Above-mentioned deployed dispensing is pumped into hopper by suction pump, and is heated up to 80 degrees Celsius, and makes pressure in hopper
For 0.2 MPa；And in process of production, 0.5% defoamer is at the uniform velocity added by proportioning from secondary hopper with small screw.This will be used
