Description
Technical field
The invention belongs to technical field of polymer materials, and in particular to a kind of high strength heat resistant flame-proof ABS alloy material.
Background technique
As a kind of plastics variety that comprehensive physical mechanical performance is very excellent, ABS is applied to vapour more and more widely
The industries such as vehicle household electrical appliances, machinery, weaving.In recent years, with the continuous improvement of automotive light weight technology level, auto industry is to ABS resin
Demand increase sharply, especially recent years, China Automobile Industry is especially swift and violent, and automotive light weight technology has become automobile material
Expect the Main way of development, the demand of automobile engineering plastics increases, and ABS has become the most plastics of the dosage on automobile
One of kind.Raising with automobile to material requirements, and heat resistance existing for ABS resin, the disadvantages of weatherability is poor,
Application on automobile is faced with formidable challenges.Instrument luster, instrument mask, heat dissipation grid door panel in terms of automobile etc. zero
Component, the components such as electric heater decoration panel, hair dryer shell, microwave oven decoration panel in terms of household electrical appliances, all to ABS resin
Propose higher heat resistant requirements.Due to the structure and composition feature of ABS resin itself, the heat distortion temperature of common ABS resin
Lower than 85 DEG C, long-term use temperature is only 80 DEG C, higher than in 90 DEG C of environment using tending to that buckling deformation occurs very
To softening risk in terms of the market prospects of ABS resin, the ABS resin of common grade is easy to by the high-impact polyphenyl of low price
The thermoplastic resin materials such as ethylene (HPS), high density polyethylene (HDPE) (HDPE) and linear low density polyethylene (LLDPE) (LDPE) substitution.By
Heat resistance modified heat-resisting ABS resin has high heat resistance, balanced mechanical property and processing performance outstanding, can part
Instead of polyester and its alloy plastic, the main flow direction of ABS resin development certainly will be become.China is to heat-proof combustion-resistant ABS resin
Market demand it is also very big, the world such as SABIC, BASF, Dow, LG, SUMSUNG renowned company all develops difference one after another
The heat-proof ABS of grade has captured the fields such as car trim, electric iron, electric cooker, shower, the hair dryer of China.
It is well known that the limit oxygen index of ABS only has 18.3 ~ 20, it is a kind of inflammable high molecular material, horizontal firing
Quickly, about 25 ~ 5lmm/mi, when burning, generates a large amount of black smokes to speed, and from continuing to burn after fire, flame is in yellow black smoke, combustion
Plastics soften, burn after burning, but drip without melting.It can cause fire because of short circuit with electronics, the electrical accessorie etc. of ABS resin manufacture
Calamity, this disadvantage limit its further application.Therefore, the anti-flammability for how improving ABS resin has become industry and extremely closes
Note and urgent problem to be solved.
For this purpose, currently in order to improve the heat resistance of flame-proof ABS, usually with, wollastonite, talcum powder etc. carry out flame-proof ABS
Heat resistance is modified, but this method the heat resistance for improving flame-proof ABS simultaneously, the toughness and flowing of flame-proof ABS can be significantly reduced
Property, while ABS resin being made to lose high-luster, it is difficult to apply in appearance member field, is not suitable for large-scale popularization application on the market.
A kind of high-intensity and high-tenacity impact resistance, and the ABS of excellent combination property are urgently developed as those skilled in the art
Alloy material.
