Problems solved by technology

[0004] Secondly, construction sites are often used outdoors, and safety helmets are more exposed to ultraviolet radiation, and the aging of materials is significantly accelerated, resulting in a significant decline in material performance and shortening the service life of helmets. Therefore, ABS materials with UV protection properties are required to ensure Safety during its lifetime
[0005] Third, for mine operations, the working environment of the industry is more demanding, because there is too much dust under the mine, if the helmet is not antistatic, then the dust is easy to accumulate, causing sparks, which will bring disaster
[0011] Although the existing ordinary ABS has superior performance, good fluidity and balanced mechanical properties, it not only maintains good impact toughness and rigidity, but also has good flame retardancy, good UV resistance and antistatic performance. product but no

Abstract

The invention relates to a fireproof anti-ultraviolet anti-static ABS material and a preparation method thereof. The preparation method comprises the following steps: weighing the following raw materials: 25 to 71 weight percent of ABS, 20 to 45 weight percent of AS, 5 to 15 weight percent of fire retardant, 2 to 10 weight percent of synergist, 1 to 5 weight percent of antistatic agent, 0.1 to 3 weight percent of lubricating agent, 0.1 to 1 weight percent of antioxidant and 0.1 to 1 weight percent of light stabilizer; adding 0 to 0.3 weight percent of white oil into the raw materials, putting the mixture into a high mixing machine to mix for 2 to 5 minutes and discharging; carrying out extrusion granulation on the discharged mixture by a double-screw extruder to obtain a product, wherein the cylinder temperature of the double-screw extruder is between 190 and 250 DEG C and the rotating speed of screws is between 180 and 600 revolutions per minute. Compared with the prior art, the ABS material of the invention has outstanding impact resistance, high glossiness, mouldability and chemical resistance and can meet testing standards of a safety helmet (GB 2811 / GB 2812).

Description

technical field [0001] The invention relates to an ABS material, in particular to a fireproof, ultraviolet-proof and antistatic ABS material which can be used for safety helmets and a preparation method thereof. Background technique [0002] ABS has good fluidity and balanced mechanical properties, and is suitable for various parts. However, general ABS has poor fireproof, anti-ultraviolet and antistatic properties, especially when there are requirements for fire, anti-ultraviolet and antistatic, it is easy to cause the impact strength of ABS to be low. ,vice versa. [0003] First of all, when safety helmets are used in construction, mine and other work sites, it is easy to cause damage to the human head due to falling objects from high altitudes, so this kind of material requires high impact resistance. [0004] Secondly, construction sites are often used outdoors, and safety helmets are more exposed to ultraviolet rays, and the aging of materials is significantly accelera...
