Step 3: premix is transferred in double screw extruder, is sequentially added glass fibre, heat stabilizer, light and is stablized Agent and nucleating agent, the extrusion temperature of double screw extruder are 280 DEG C, and the extrusion revolving speed of double screw extruder is 500 revs/min, are squeezed It is granulated out, obtains vehicle outer door knob fiberglass reinforced modification of nylon.
Preferably, selected glass fibre is roving glass fiber, length 17-20mm.
Long glass fiber reinforced modified nylon materials have the characteristics such as high intensity, rigidity, bending strength, tensile strength, especially suitable Use is closed in the frequent occasion of high/low temperature alternation, mechanical performance integrally enhances.
Preferably, addition modified polyether ether ketone includes the raw material composition of following parts by weight:
Improve the processing performance and mechanical property of composite material.
Preferably, epoxy-modified polyethylene is selected, so that composite material has excellent strong alkali-acid resistance corrosivity Energy and mechanical property.
Preferably, selecting one of polystyrene thermoelastic body-SBS or SIS, the cryogenic property of material can obviously improve And impact strength.
Preferably, selecting plasticized modifier MBS, there is toughening effect to entire co-mixing system, there is composite material Good flame retardant property and physical mechanical property.
Preferably, the heat stabilizer selected is mantoquita type thermal stabilizing agent.
The long term heat ageing performance of PA6 can be improved, resist chemical attack and harsh climate condition, and have certain Lubrication and oxidation resistant effect.
Preferably, the nucleating agent selected is beta crystal-type nucleater.
The addition of nucleating agent can preferably keep the dimensional stability of product, while shortening molding cycle and improving production Rate improves the demoulding and mechanical performance (improving tensile strength and hardness) of material.
Preferably, the light stabilizer selected is hindered amine light stabilizer.
Make PA6 photooxidation aging property be improved significantly.
In conclusion the invention has the following advantages:
1, nylon heat stabilizer is added in glass fiber reinforcement PA6, the long term heat ageing performance of PA6 can be improved, resists Chemical attack and harsh climate condition, and have certain lubrication and oxidation resistant effect;The addition of light stabilizer makes The photooxidation aging property of PA6 be improved significantly;The addition of nucleating agent can preferably keep the dimensional stability of product, contract simultaneously Short molding cycle improves productivity, improves the demoulding and mechanical performance (improving tensile strength and hardness) of material;Modified polyether ether The addition of ketone improves the processing performance and mechanical property of composite material.
2, epoxy resin, the sky formed after the functional groups such as the hydroxyl contained, epoxy group, with the crosslinking of amine esters are selected Between structure so that composite material have excellent strong alkali-acid resistance corrosive nature and mechanical property;Polystyrene thermoelastic body is selected, It can obviously improve the cryogenic property and impact strength of material;Plasticized modifier MBS is selected, has toughening to entire co-mixing system Effect, makes composite material have good flame retardant property and physical mechanical property.
3, using the fiberglass reinforced modification of nylon of formula production have strong alkali-acid resistance, low-temperature flexibility, fatigue durability it is strong, The advantages of good stability of the dimension.
Specific embodiment
The modified polyether ether ketone includes: 40 parts of P-hydroxybenzoic acid, 30 parts of ethylene terephthalate, 5 parts of short glass fiber With 10 parts of thermotropic liquid crystal polymer.
Raw material are weighed according to the formula ratio of each embodiment of following table one and each comparative example of table two, by weighed PA6, asphalt mixtures modified by epoxy resin Rouge, modified polyether ether ketone, polystyrene thermoelastic body, plasticized modifier (MBS), which are uniformly mixed, to be added in high-speed mixer, revolving speed 1000 revs/min, 30min is mixed, after mixing well, obtains premix;Premix is transferred in double screw extruder, successively plus Enter glass fibre, heat stabilizer, light stabilizer and nucleating agent, the extrusion temperature of double screw extruder is 280 DEG C, twin-screw extrusion The extrusion revolving speed of machine is 500 revs/min, and extruding pelletization obtains vehicle outer door knob fiberglass reinforced modification of nylon.
The formula ratio of each embodiment of table one weighs raw material
To the vehicle outer door knob fiberglass reinforced modification of nylon of each embodiment preparation, result verification test is carried out, is pressed The standard of two the key technical indexes of table is tested, and experimental test result such as table three is verified.
Two the key technical indexes of table
