Abstract
The invention discloses an alcoholysis resistant PA66 composite material used for automobiles and a preparation method thereof. The method comprises the following steps: adding PA66 except for glass fiber and carbodiimide in a formula into a high-speed mixer for mixing evenly; taking out the mixture from the high-speed mixer after the above materials are mixed evenly; adding the materials mixed through the high-speed mixer into a double-screw extruder from a main feeding opening thereof; adding the glass fiber into the double-screw extruder from a secondary feeding opening thereof in metering; evenly mixing the materials in the formula in the double-screw extruder; controlling the temperature of the double-screw extruder at 240-270 DEG C; and then extruding cutting grains to obtain the PA66 composite material. The invention provides a special material used for auto water tank parts, which has low cost, high performance, raw white (high degree of freedom for color blending) and high resistance to ethylene glycol.
Description
Technical field
The present invention relates to the automotive material field, refer more particularly to a kind of improvement of proprietary material of radiator parts.
Background technology
PA has excellent physicals, chemical resistant properties and workability, has excellent intensity, suitable toughness and certain heatproof air aging performance after strengthening through GF, can be competent at Working environments such as some high temperature, greasy dirt.PA has above characteristic, depends primarily on to contain the polar amide group in its structure.But amide group very easily with alcohols isopolarity solvent generation hydrolysis reaction, make common PA matrix material not have ethylene glycol resistant (main component of automobile antifreeze solution) performance, limited the application of PA material on the radiator parts greatly.
" modern plastics processed and applied " (1995, the 6 phases, 14-19 page or leaf) reported at glass fibre and strengthened the shock strength and the anti-deicing fluid ability of adding MAH-g-PP raising matrix material in the PA66 matrix material.Utilize nonpolar polyolefine can block the suction alcohol passage of material, delay the infiltration of ethylene glycol, significantly improve the anti-alcoholysis ability of PA66.But, can not use as the radiator component materials because of the MAH-g-PP high temperature of the parts of anti-radiator the (90-140 ℃) working conditions not.Patent (CN:101191015A) has been reported by adding copper halide and nucleator and has been improved the anti-alcoholysis performance that alkali free glass fibre strengthens the PA66 material.But add copper halide as main hydrolysis-resisting agent, can make material painted, and copper halide and nucleator system do not have cost advantage.Low cost, high-performance, this white (the color matching degree of freedom is big), the ethylene glycol resistant PA66 matrix material that satisfies radiator parts working condition requirement become automotive material supplier's research and development emphasis.
Summary of the invention
The objective of the invention is to provide a kind of low cost, high-performance, alcoholysis resistant PA 66 composite material used for automobiles that the color matching degree of freedom is big and preparation method thereof at the deficiencies in the prior art.
Above-mentioned purpose of the present invention can be achieved through the following technical solutions:
A kind of alcoholysis resistant PA 66 composite material used for automobiles and preparation method thereof mixes PA66 and carbodiimide 3-5 minute in rotating speed 350-1300 rev/min high-speed mixer earlier; Resultant compound adds the main charging opening of twin screw extruder; Second charging opening of glass fibre at twin screw extruder is metered into, and extruder temperature is controlled at 240 ℃-270 ℃, and the twin screw extruder screw speed is 250-400rpm, 20-60 ℃ of tank temperature, and the dicing machine rotating speed is 600-800rpm.Extruding pelletization obtains the PA66 matrix material then.
Above-mentioned each component (by quality %) formula rate is as follows:
PA66 58-69.9％
Carbodiimide 0.1-2%
Glass fibre 30%-40%
Above-mentioned each component formula rate summation is 100%.
The viscosity of described PA66 resin is 2.4-3.2dl/g.
Described carbodiimide mass content is 0.1-0.3%.
Described carbodiimide is any one or two kinds of mixture in aliphatics, the alicyclic or aromatic polycarbodiimide, and its polymerization degree is not less than 4.
Described glass fibre is for the process silane coupling agent is handled, filament diameter is the alkali-free glass fiber of 10-15 micron.
Outstanding effect of the present invention is:
Manufacture method of the present invention is simple, and technology is easy.The technique effect that the glass fibre that proposes according to above technical scheme strengthens the PA66 matrix material is embodied in: provide that a kind of low cost, high-performance, color matching degree of freedom are big, the radiator component-dedicated material of high ethylene glycol resistant.This material still keeps very high mechanical property after soaking in 140 ℃, volume fraction are 50% aqueous glycol solution, and dimensional stabilizing.
The present invention will be further described below in conjunction with embodiment
