Abstract
The invention relates to a halogen-free flame retardant modified plastic. The plastic is prepared from the following substances in parts by weight: 20-50 parts of polyethylene, 1-15 parts of melamine cyanurate, 0.1-3 parts of zinc stearate, 1-20 parts of polybutylene terephthalate and 1-5 parts of zinc oxide. The halogen-free flame retardant modified plastic meets the requirement of flame retardance and is used for reducing the environmental load.
Description
Technical field
The present invention relates to the modified plastics field, relate in particular to a kind of halogen-free flame-retardant modified plastics.
Background technology
Vinyon is widely used in the fields such as fire prevention, mildew-resistant, waterproof, sound insulation, sound-absorbing, buffering, but only has carbon, two kinds of elements of hydrogen in the vinyon, so as easy as rolling off a log burning.Melting is low serious during burning, thereby limited the use of vinyon.
Summary of the invention
The purpose of this invention is to provide a kind of halogen-free flame-retardant modified plastics.
In order to realize purpose of the present invention, the invention provides a kind of halogen-free flame-retardant modified plastics, it is to be made by the material of following weight proportioning: polyethylene 20-50 part, melamine cyanurate 1-15 part, Zinic stearas 0.1-3 part, polybutylene terephthalate 1-20 part and zinc oxide 1-5 part.
Preferably, halogen-free flame-retardant modified plastics of the present invention is to be made by the material of following weight proportioning: 3 parts in 45 parts of polyethylene, 5 parts of melamine cyanurates, 0.5 part of Zinic stearas, 10 parts of polybutylene terephthalates and zinc oxide.
Halogen-free flame-retardant modified plastics of the present invention satisfies the flame retardant resistance requirement and is used for alleviating carrying capacity of environment.
Embodiment
Below the invention will be further described for the description by embodiment, but this is not to be limitation of the present invention, those skilled in the art are according to basic thought of the present invention, can make various modifications or improvement, but only otherwise break away from basic thought of the present invention, all within the scope of the present invention.
Embodiment 1
Polyethylene 450 grams, melamine cyanurate 50 grams, Zinic stearas 0.50 gram, polybutylene terephthalate 100 grams and zinc oxide 30 grams are mixed, use twin shaft mixing tank (diameter: 45mm, L/D:42), under 230 ℃ of barrel temperatures and screw speed 100rpm, carry out melting mixing.Mixture is melt extruded with pencil.Then the bundle cooling of melting is cut to prepare modified plastics.
Embodiment 2
According to preparing modified plastics with embodiment 1 identical mode, difference is, melamine cyanurate is 10 grams.
Embodiment 3
According to preparing modified plastics with embodiment 1 identical mode, difference is, melamine cyanurate is 150 grams.
Embodiment 4
According to preparing modified plastics with embodiment 1 identical mode, difference is, does not add melamine cyanurate.
Embodiment 5
According to preparing modified plastics with embodiment 1 identical mode, difference is, does not add zinc oxide.
Experimental example
About flame retardant resistance, require product to satisfy vertical sample combustion test (vertical-specimenflame test), this test is known as the VW-1 test, and is one of requirement the strictest in the UL standard.Test with the sample of preparation among 10 embodiment 1 to 4 respectively.
10 samples are carried out the vertical sample combustion testing of VW-1 of the 1080 chapters and sections regulation of UL standard 1581.Standard of evaluation is as follows: each sample lighted for 15 seconds.This lights repetition 5 times.When sample satisfied following standard, this sample was cited as satisfactory:
(a) flame must extinguish within 60 seconds,
(b) be in the combustion debris that the absorbent cotton below the sample can not be fallen and ignite, and
(c) kraft paper that invests sample top can not be ignited or be burnt.
The result
For the sample of 10 embodiment 1, find all by flame-retardancy standards, satisfy the flame retardant resistance requirement fully;
For the sample of 10 embodiment 1, find to have 3 samples by flame-retardancy standards, all the other 7 samples can't pass through flame-retardancy standards;
For the sample of 10 embodiment 1, find to have 3 samples by flame-retardancy standards, all the other 7 samples can't pass through flame-retardancy standards;
For the sample of 10 embodiment 4, find all can't pass through flame-retardancy standards;
For the sample of 10 embodiment 5, find to have 7 samples by flame-retardancy standards, all the other 3 samples can't pass through flame-retardancy standards.
