Description
Technical field
The present invention relates to technical field of alloy material, be related to it is a kind of with high tenacity, high heat resistance, noise reduction PC/ABS material
Preparation method.
Background technique
The noise of car room is mainly derived from generation frictional vibration between each mating position of automotive interior gadget and is produced
Raw noise, appears in internal hilar plate handle, panel mostly, at the components such as middle control station and air-conditioner air outlet.Such as inside door
Panel nearby is electroplated for handle and there are many gomphosis part of PC/ABS class.Noise problem frequently occurs when pressing component.Due to component
Between gap it is small, generally using lubricating grease reduce noise, at high cost, process is tedious, and is unable to reach long-term noise resistance effect.
The present invention be exactly introduce a kind of high tenacity for meeting automobile interior decoration application requirement, high heat resistance, noise reduction PC/ABS material
The preparation method of material.
Summary of the invention
The object of the present invention is to provide it is a kind of with high tenacity, high heat resistance, noise reduction PC/ABS material preparation method, with
Solve the above problem of the prior art.
The purpose of the present invention is achieved through the following technical solutions.
It is a kind of with high tenacity, high heat resistance, noise reduction PC/ABS material, by polycarbonate, acrylonitrile-butadiene-benzene second
Alkene copolymer, compatilizer, noise reduction auxiliary agent and heat stabilizer composition；By weight, described polycarbonate 55-65 parts；Propylene
Nitrile -25-45 parts of butadiene-styrene；3-5 parts of compatilizer, 3-10 parts of noise reduction auxiliary agent；0-1.5 parts of heat stabilizer.
The polycarbonate is the PC product of phosgenation synthesis.
The acrylonitrile-butadiene-styrene copolymer is the ABS product of mass polymerization.
The compatilizer is in maleic anhydride grafted ABS and methacrylic acid-butadiene-styrene terpolymer
It is one or more of.
The noise reduction auxiliary agent is polycthylene grafted object AS100, is selected from Japan Oil Co.
The heat stabilizer is one or more of Hinered phenols antioxidant, phosphoric acid ester antioxidant.
It is above-mentioned with high tenacity, high heat resistance, noise reduction PC/ABS material preparation method, the steps include:
1) each raw material is weighed by above-mentioned formula；
2) screw diameter 35mm, draw ratio is added with Double-screw feeder continuous uniform after dry raw material mixing
In the double screw extruder main barrel of L/D=40, main barrel Discrete control temperature is exported from feed opening to head as 120 DEG C, 250
DEG C, 250 DEG C, 245 DEG C, 245 DEG C, 240 DEG C, 240 DEG C, twin-screw revolving speed be 500 revs/min, squeeze out material strip by sink cool down
Pelletizing obtains product afterwards.
A kind of PC/ABS material of technical solution of the present invention having the beneficial effect that by adopting the above technical scheme, not only has
High heat resistance, high low-temperature impact toughness, while also there is noise reduction effect.
Specific embodiment
Below by specific embodiment, the present invention is further illustrated, but the embodiment is merely to illustrate the present invention
Rather than the limitation present invention.
The raw materials used in the present invention:
PC: South Korea LG chemistry, 201-10
ABS: Sinopec Shanghai Gaoqiao petrochemical industry Co., Ltd, 3513；
Compatilizer 1:ABS-g-MAH, self-control；
Compatilizer 2: South Korea LG chemistry, EM500；
Heat stabilizer 1: Hinered phenols antioxidant, the production of DOUBLE BOND CHEMICAL IND. Co., Ltd, 1010；
Heat stabilizer 2: phosphoric acid ester antioxidant, the production of Ciba company, Switzerland, 619F；
Noise reduction auxiliary agent: Japan Oil Co, AS100.
Properties of product test method:
Notch impact strength: ISO 179-1/1eA method, KJ/m are pressed2；
Vicat softening temperature: press 306 method of ISO, B50, DEG C；
Noise test: using the friction wear testing machine of Germany Ziegler production, according to VDA230-206 method, by negative
40N is carried, speed 10mm/s, amplitude 20mm are tested three times back and forth.Risk index RPN (0-10 grades) are generated by abnormal sound to evaluate material
The abnormal sound of material generates risk.When abnormal sound generates risk below 3, it is extremely low to be considered as noise probability of happening, and 4-5 grade non-medium noises are sent out
Raw probability, being greater than 6 grades is high noisy probability of happening.
Embodiment 1-6 and comparative example 1
It is double being used after dry ABS resin, heat-resistant agent, stabilizer and delustering agent etc. are by composition ratio mixing in table 1
Screw feeder continuous uniform is added in double screw extruder (screw diameter 35mm, draw ratio L/D=40) main barrel, main barrel
Discrete control temperature (from feed opening to head export) is 120 DEG C, 250 DEG C, 250 DEG C, 245 DEG C, 245 DEG C, 240 DEG C, 240 DEG C,
Twin-screw revolving speed is 500 revs/min, squeezes out material strip pelletizing after sink is cooling and obtains product.The said goods are dried in air blast
Standard batten is molded into plastic-injection moulding machine after dry 4 hours in 100 DEG C in case, 240 DEG C of injection temperature.The sample of injection formed
Item is immediately placed in glass desicator to be tested for the property after being placed at room temperature at least 24 hours.Test result is shown in Table 1.
