Abstract
The invention provides low smoke, zero halogen and flame retardant plastics which are produced by extruding mixed raw materials, wherein the components of the raw materials and the weight percentages of the components are as follows: 40%-60% of ethylene vinyl acetate (EVA), 10%-20% of aluminium hydroxide, 20%-30% of magnesium hydroxide, 1%-2% of antioxidant 1010, 2%-3% of barium stearate and 5%-7% of amino-polyol esters. The production method of the low smoke, zero halogen and flame retardant plastics is that: the raw materials are uniformly mixed, then are extruded through an extruder and granulated, so the low smoke, zero halogen and flame retardant plastics are produced. The low smoke, zero halogen and flame retardant plastics not only have excellent flame retardant, but also do not contain halogen in the materials, cannot release a large quantity of smoke and hydrogen halide gas during the combustion, have good safety and environmental performance, also have better mechanical property and processing property simultaneously, and are applicable to branch cables, electric equipment and other fields.
Description
Technical field
The present invention relates to plastics and preparation method thereof technical field, more specifically relate to a kind of low-smoke non-halogen flame-retardant injection molding material and preparation method thereof.
Background technology
At present, the application of plastics spreads all over the every field of industry, agricultural and life, such as electric wire, material of construction, mechanical means parts etc., and the main component of plastics is high molecular polymers, these high molecular polymers are generally inflammable, because fire is very harmful, so the flame retardant of plastic problem is subject to people's attention.The method that existing plastic flame is generally taked is to add fire retardant in high molecular polymer, and contain halogen in most fire retardants, can discharge a large amount of smog and hydrogen halide during burning, these smog and hydrogen halide are toxic and by strong smothering action to human body, also can produce corrosive nature to equipment.In recent years, the low-smoke non-halogen flame-retardant agent finds application in plastics gradually, but usually has the mechanical property of plastics or the shortcoming that processing performance descends.
Summary of the invention
The purpose of this invention is to provide preferably low-smoke non-halogen flame-retardant injection molding material and preparation method thereof of a kind of flame retardant properties, mechanical property, processing performance, this low-smoke non-halogen flame-retardant injection molding material is applicable to various branching cables, electrical equipment and related accessory.
Technical scheme solved by the invention is: a kind of low-smoke non-halogen flame-retardant injection molding material, make by extruding after the raw material blend, and it is characterized in that the feed composition of described plastics and the weight percentage of each component are:
