Abstract
The invention discloses a glass-fiber-enhanced nylon 66/nylon 6 composite material and a preparation method thereof. The composite material comprises the components of, by weight, 25-40% of PA66, 13-38% of PA6, 20-35% of glass fiber, 0.5-1.5% of a nano-grade nucleating agent, 9% of a halogen-free flame retardant, 0.6-0.9% of a lubricating dispersant, 0.1-0.4% of a UV-absorbing agent, and 0.5-1.5% of an antioxidant. According to the invention, the above raw materials except the glass fiber are added into a high-speed mixer; the materials are uniformly mixed, and the mixture is subjected to extrusion granulation by using a double-screw extruder; the glass fiber is added from a second feeding port; and a processing temperature is 200-300 DEG C. Compared with prior arts, the composite material provided by the invention is halogen-free and environment-friendly, and has the advantages of high impact resistance, ultraviolet oxidation resistance, seawater corrosion resistance, alcohol corrosion resistance, detergentcorrosion resistance, and the like. The composite material can be widely applied in engine hoods of cars, ships, and the like.
Description
Technical field
The present invention relates to engineering plastics field, be specifically related to a kind of preparation method of glass fiber enhanced nylon 66/nylon 6 composite material.
Background technology
Because polyamide abrasion-proof damage property is good, have good physical strength and rigidity, therefore be widely used in the fields such as automotive trim and functional part, electronic apparatus component, transportation equipment, engine for boat cover, weaving, its consumption has occupied engineering plastics prostatitis, in a lot of application, has replaced metallic substance.But due to drawbacks limit such as the polarity of nylon are large, water absorbability is strong, size is unstable its range of application.
Summary of the invention
The object of the invention is exactly the above-mentioned shortcoming existing in order to overcome nylon composite materials, by changing filling kind and filler mode, prepares a kind of glass fiber enhanced nylon 66/nylon 6 composite material, can be applicable to radiator, steamer hood.
The object of the invention can be achieved through the following technical solutions:
(1) according to the weight percentage of following component, get the raw materials ready
PA66 25~40%
PA6 13~38%
Glass fibre 20-35%
Nano-nucleating agent 0.5-1.5%
Halogen-free flame retardants 9%
Lubrication dispersing agent 0.6-0.9%
Uv-absorbing agent 0.1-0.4%
Oxidation inhibitor 0.5-1.5%
(2) by PA66, PA6 at 80-95 ℃ dry 12 hours, then add high-speed mixer to mix other all components except glass fibre in formula, estimate mixing time 3 minutes, to be mixedly from high-speed mixer, take out compound after evenly.From the main charging opening of twin screw extruder, add the material mixing through high-speed mixer, the second charging opening by glass fibre at twin screw extruder is metered into, all materials in formula are mixed in twin screw extruder, extruder temperature is controlled at 200 ~ 300 ℃, screw rod revolution 200-400 rev/min, then extrudes and obtains glass fiber reinforced PA66/PA6 matrix material.
Beneficial effect of the present invention is: improved tensile strength, the flexural strength of PA66/PA6 matrix material, improved its heat-drawn wire, resistance to alcohol, corrosive properly, have UL94 V-1 level flame retardant properties.
