Description
Technical Field
The invention relates to a resin composition, in particular to a flame-retardant ABS resin composition with low infrared reflectivity and a preparation method thereof.
Background
The smoke alarm is common safety equipment in modern life, and the working principle of the smoke alarm is that the infrared detector senses the change of smoke concentration, so that the alarm and prompt are realized, and the occurrence of fire is avoided. The smoke alarm mainly comprises an optical maze, an infrared generating and receiving electric tube, and the wavelength of infrared rays is generally in the range of 800-1500 nm. When no smoke exists in the environment, the receiving tube can not receive infrared light theoretically; when smoke exists in the environment, the particles of the smoke can enter the labyrinth to enable infrared light emitted by the generating tube to be scattered, the intensity of the scattered infrared light and the smoke concentration have a certain linear relation, and the receiver can prompt or give an alarm when receiving the change of the infrared light intensity. Smoke alarms, however, sometimes have false alarm behavior, which reduces the reliability of the device. One of the main reasons for false alarms is that the reflectivity of the optical maze itself is too large, resulting in infrared intensity fluctuations at the receiver. By reducing the infrared reflectivity of the surface of the optical labyrinth, the false alarm rate of the alarm can be effectively reduced.
The optical labyrinth is generally an injection molding part of the flame-retardant ABS, and in order to reduce the false alarm rate of the smoke alarm, the infrared light reflectivity of the flame-retardant ABS needs to be reduced. The factors that influence the reflectivity mainly include the reflectivity and color of the binder material. Among the different colors, the reflectance of black is the lowest. The infrared reflectivity of the black flame-retardant ABS of different flame-retardant systems at 800-1500nm is generally 8-15%, and if the reflectivity can be reduced to be below 3%, the false alarm rate of the smoke alarm can be greatly reduced.
The common flame retardant system of ABS is a halogen flame retardant and antimony trioxide synergistic system. In this system, the reflectance of antimony trioxide is the highest, and therefore, it is necessary to reduce the amount added as much as possible. If antimony trioxide is not added to ABS, more halogen flame retardant is required to be added, so that the cost is obviously increased, and meanwhile, the reflectivity can be reduced by about 1 percent, and the target of less than 3 percent still cannot be achieved. Reducing the reflectivity of flame retardant ABS is an industry problem, and no effective technology is available at present for reducing the reflectivity of flame retardant ABS.
Disclosure of Invention
The present invention has been made to solve the above problems, and an object of the present invention is to provide a flame retardant ABS resin composition having a low infrared reflectance, which can significantly reduce the reflectance of flame retardant ABS.
The purpose of the invention can be realized by the following technical scheme:
a flame-retardant ABS resin composition with low infrared reflectivity comprises the following components in percentage by weight:
further, the ABS resin is acrylonitrile-butadiene-styrene copolymer.
Furthermore, the bromine flame retardant is one or a mixture of a plurality of tetrabromobisphenol A, decabromodiphenylethane, tri (bromophenyl) triazine, brominated epoxy, hexabromocyclododecane, tetrabromophenol and brominated styrene. The type of the flame retardant has little influence on the reflectivity of the final product, and all bromine flame retardants suitable for flame-retardant ABS can be used.
Further, the antimony compound is antimony trioxide. The content of antimony trioxide is not more than 6 parts because the reflectance of antimony trioxide is the highest, and further increasing the content of antimony trioxide leads to an increase in reflectance.
Further, the chlorinated polyethylene is abbreviated as CPE, and the chlorine content is 25-40%. CPE is essential in this flame retardant ABS system because CPE not only acts as a synergistic flame retardant, but is also a compatibilizer for ABS and TPX. Too high or too low chlorine content leads to poor compatibility with ABS and TPX, resulting in deterioration of flame retardancy and mechanical properties.
Further, the poly-4-methylpentene-1 (TPX for short) is a key component for reducing the infrared reflectivity.
Further, the anti-dripping agent is 300-500 ten thousand Polytetrafluoroethylene (PTFE).
Further, the antioxidant is a hindered phenol antioxidant or a phosphite antioxidant;
further, the lubricant is one or a mixture of a plurality of silicone oil, ethylene bis stearamide, magnesium stearate, polyethylene wax and ethylene-vinyl acetate copolymer.
The invention also provides a preparation method of the flame-retardant ABS resin composition with low infrared reflectivity, which comprises the following steps:
(1) weighing the following components in parts by weight: 100 parts of ABS resin, 10-25 parts of brominated flame retardant, 3-6 parts of antimony compound, 10-38 parts of chlorinated polyethylene, 15-20 parts of poly-4-methylpentene, 0.1-0.5 part of anti-dripping agent, 0.2-1 part of antioxidant, 1-3 parts of lubricant and 2-8 parts of carbon black;
(2) adding the components in the step (1) into a high-speed mixer according to the parts by weight, fully mixing, then placing into a screw machine, performing melt extrusion at the extrusion temperature of 230 ℃ and the screw rotation speed of 500 revolutions per minute of 200-.
Compared with the prior art, the invention has the following advantages:
1. TPX is introduced into the resin composition, and the resin is resin with the lowest refractive index, the highest transmittance and the lowest infrared reflectivity, so that the reflectivity of the flame-retardant ABS can be obviously reduced. Due to the poor compatibility between TPX and ABS, the flame retardance and mechanical properties of flame retardant ABS are significantly reduced by the addition of TPX. And the addition of CPE can improve the dispersion of TPX in ABS, so that the flame retardance and mechanical properties are maintained, and the infrared reflectivity of the flame-retardant ABS is effectively reduced.
2. After the compatibility is solved, the high dispersion of TPX in the flame-retardant ABS can be realized, the infrared reflectivity of the flame-retardant ABS is reduced from 15% to 1.3-3%, and the flame-retardant ABS resin composition with low reflectivity is obtained.
