Abstract

The invention discloses an impact-resistant, flame-retardant and antibacterial ABS material for smart home appliances and a preparation method thereof, and relates to the technical field of ABS materials. The present invention comprises the following components by weight: 55-65 parts of ABS resin, 2-5 parts of antimony trioxide, 10-15 parts of bromotriazine, 4-6 parts of decabromodiphenylethane, SBS antibacterial masterbatch 12‑16 parts, 0.2‑0.4 parts of antioxidant, 0.2‑0.4 parts of heat stabilizer, 0.2‑0.4 part of light stabilizer, 0.2‑0.5 part of anti-dripping agent, 0.4‑0.7 part of lubricant, 0.4‑0.4 part of antistatic agent 0.6 part; The present invention also provides the preparation method of above-mentioned ABS material, each component forms through mixing, co-extrusion, cooling and granulation. The flame retardant grade of the ABS material of the present invention reaches 5VA grade, meets the flame retardant grade requirements of smart home appliances, has pure color, good fluidity, good antibacterial effect, strong impact resistance and excellent mechanical properties.

Description

technical field [0001] The invention belongs to the technical field of ABS materials, in particular to an impact-resistant, flame-retardant and antibacterial ABS material for smart home appliances and a preparation method thereof. Background technique [0002] With the rapid development of the economy and the improvement of people's living standards, people pay more and more attention to the quality of life and life safety. As a product that directly contacts the skin of the body, the toilet seat has a particularly important impact on human body safety. The traditional toilet cover is gradually replaced by the smart toilet cover due to its low humanized design. The smart toilet cover has automatic heat preservation, heating and cleaning functions, so it has very strict requirements on materials. In addition to the high physical and mechanical properties of the traditional toilet cover, It also has antibacterial, antistatic, flame retardant and other properties. [0003] Acr...
