Abstract
The invention relates to a modified PP flame retarding material, in particular to an efficient modified PP composite material with nanometer silicon carbide carrying composite flame retardant and a preparation method thereof. According to the preparation process of the composite material, dimethyl methylphosphonate and melamine cyanurate serve as the environment-friendly composite flame retarding synergist, and permeates to be carried by nanometer silicon carbide under high pressure, the processed composite flame retardant is distributed more evenly in PP, and the synergia performance is more obvious; because the nanometer silicon carbide is added, the mechanical property of the PP material is improved, the heat conduction capacity of the material is further improved, and the flame retarding speed is higher. The prepared modified PP composite material is simple in production process, high in quality and low in price and safe and environment-friendly to use, and has very high market competitiveness.
Description
Technical field
The present invention relates to a kind of MODIFIED PP flame-proof material, be specifically related to a kind of high effective and modified PP compound material utilizing nanometer silicon carbide load composite flame-retardant agent and preparation method thereof.
Background technology
Polypropylene (PP) is one of five large general-purpose plastics, has nontoxic, odorless, tasteless feature, and proportion is little, be easy to machine-shaping, application is very extensive, but PP material oxygen index is on the low side, belongs to inflammable material, in order to widen its use range, need to increase its flame retardant properties.
In traditional production process, in order to improve the flame retardant properties of PP, many employings are direct in process of production expects mixing granulation by fire retardant and PP, this just makes fire retardant easily disperse inequality wherein, and the flame retardant effect of material is low, adds the consumption of fire retardant, in order to improve this situation, therefore need to set about from technique and formula, improve the utilization ratio of fire retardant in PP material, thus obtain the more excellent flame-proof material of performance.
Summary of the invention
The object of the invention is to, provide a kind of high effective and modified PP compound material utilizing nanometer silicon carbide load composite flame-retardant agent and preparation method thereof, to obtaining the PP material with good flame retardant effect, to achieve these goals, the technical solution used in the present invention is as follows:
A kind of high effective and modified PP compound material utilizing nanometer silicon carbide load composite flame-retardant agent and preparation method thereof, it is characterized in that, this compound material is made up of the raw material of following weight part: PP 50-60, nanometer silicon carbide 10-15, dimethyl methyl phosphonate 5-8, melamine cyanurate 2-3, methyl-silicone oil 1-2, glycidyl methacrylate 3-4, silane coupling agent 0.8-1, distearyl pentaerythrityl diphosphite 0.05-0.1, ultra-fine rubber powder 10-12.
Described a kind of high effective and modified PP compound material utilizing nanometer silicon carbide load composite flame-retardant agent and preparation method thereof, is characterized in that, described preparation method comprises following steps:
(1) first nanometer silicon carbide is mixed with dimethyl methyl phosphonate, melamine cyanurate, silane coupling agent, after stirring completely, mixture is forced into 60-80Mpa, slow release after keeping 50-60min, material to be mixed is fully uniformly mixed after returning to normal pressure again, obtains nanometer silicon carbide load composite flame-retardant agent materials for later use;
(2) material of step (1) gained is dropped in high speed mixer together with remaining composition mix, send into extruding pelletization in dual-screw pelletizer, obtain MODIFIED PP flame-proof material.
Beneficial effect: the present invention is using dimethyl methyl phosphonate, melamine cyanurate as environment-friendly composite flame retardant synergistic agent, and by its under elevated pressure conditions osmotic load in nanometer silicon carbide, composite flame-retardant agent after such process distributes more even in PP, synergy achievement is more remarkable, and the nanometer silicon carbide added not only improves the mechanical property of PP material, also improve the capacity of heat transmission of material further, fire-retardant speed is faster; MODIFIED PP compound material production technique prepared by the present invention is simple, and product super quality and competitive price, use safety environmental protection, has the market competitiveness.
