Description

A kind of high rigidity fire-retardant PA/ABS/PBI plastic alloy and preparation method thereof

Technical field

Present invention relates particularly to a kind of high rigidity fire-retardant PA/ABS/PBI plastic alloy and preparation method thereof.

Background technology

Plastic alloy be to utilize the method for physical blending or chemical graft and obtain high-performance, functionalization, customizations One class new material.Plastic alloy product can be widely used for automobile, electronics, precision instrument, office equipment, packaging material, Building wood The fields such as material.It can improve or improve the performance of existing plastics and reduce cost, it has also become the product enlivening the most in plastics industry One of kind, increase very rapid.With China's sustained and rapid development of economy, a few years from now on China plastic alloy market demand is dived Power is huge, especially the rapid growth of telecommunications, automobile, building industry, pulls on China's engineering plastic alloy industry fast-developing. Expecting 2008, China five large-engineering plastics aggregate demand is up to 1,000,000 tons, and the demand of five big synthetic resin is up to 52000000 tons, one of maximum importer of whole world plastic alloy will be become.The nearest more than ten years, the average annual demand of world's plastic alloy Growth rate is about 10%, and wherein the growth rate of the highest engineering plastic alloy of added value is more up to about 15%, become respectively across The kind of company of state active development.In the industrialized plastic alloy kind of the U.S., Europe, Japan, engineering plastic alloy accounts for The overwhelming majority, alloying has become the main method of current engineering plastic modification.And China's engineering plastic alloy kind is few, quality Difference, annual import volume accounts for more than the 60% of total demand.

Polyamide (PA) is the extensive engineering plastic resin of a kind of use.It is to contain recurring amide radical on molecular backbone Group-[NHCO]-the general name of thermoplastic resin；Due to unique low-gravity, high-tensile, wear-resisting, self lubricity good, impact Tenacity excellent, there is the hard and soft performance having both and the attention of winning people, its processing is easy in addition, efficiency is high, light specific gravity (only The 1/7 of metal), various goods can be processed into replace metal, be widely used in automobile and transportation.

PBI is the abbreviation of polybenzimidazoles, English name Polybenzimidazoles, belongs to unformed special engineering and moulds Material.PBI is the high performance resin material being gone out with USAF material laboratory joint development by US National Aeronautics and Space Administration, tool Have very excellent heat-resisting quantity, lower temperature resistance, mechanical property and fire resistance, there is wear-resisting, radiation hardness, acid and alkali-resistance simultaneously Property, it is the high performance resin material of a kind of great application prospect, it is all that application relates to Aero-Space, optics, microelectronics etc. Many high-tech areas.With the needs of technology development, the application of PBI is also gradually to civilian transfer.But due to PBI fiber axis To tension stress and anti-shearing poor, hinder its large-scale application.

Acrylonitrile-butadiene-phenylethylene copolymer (ABS), has excellent resistance to impact, good cryogenic property and resistance to Chemicals, good stability of the dimension, lustrous surface are good, good fluidity, it is easy to processing.The performance of ABS is between general-purpose plastics And between engineering plastics, having good mouldability, the product surface processing is bright and clean, additionally, it is strong also to have higher impact Degree and preferable chemical stability, but its heat resistance and toughness are all poor.

In the market for having high rigidity, the plastic alloy demand of fire resistance all increases day by day, but not corresponding Product corresponding therewith.Rare high rigidity flame retardant plastics alloy on domestic market, a small amount of sale and public praise are preferably substantially Imported product, the occupation rate of market of home products is less.To this end, we set about from formula and the technique of product, develop new height Performance materials, provides a kind of high rigidity fire-retardant PA/ABS/PBI plastic alloy and preparation method thereof.
