Abstract
The invention discloses a polycarbonate film, and belongs to the field of high polymer materials. The film is prepared from the following raw materials in parts by weight: 100 parts of polycarbonate, 4-8 parts of polypropylene, 2-4 parts of nanometer titania, 5-8 parts of nano calcium carbonate, 0.02-0.06 part of a silane coupling agent, 35-42 parts of a fire retardant, 1-2 parts of an antistatic agent, 0.1-0.5 part of a light stabilizer and 0.01-0.4 part of an anti-dropping agent. By selecting silicone flame retardants, the flame retardant efficiency is high, and the silicone flame retardants can be flame retardant, and can form a homogeneous insulated carbonization Si-C layer after being burnt with PC, thereby playing the role of preventing internal unburned PC from contacting external oxygen and inhibiting further combustion of the materials; and the silicone flame retardants are also capable of reducing the glass transition temperature of lower polyolefin, and are compatible with polyolefin, so that the film has scratch resistance due to nano silica.
Description
?
Technical field
The invention belongs to polymeric material field, specifically a kind of polycarbonate film.
Background technology
Polycarbonate (PC) has the mechanical property of aggregative equilibrium, dimensional stability and resistance toheat, especially with the resistance to impact shock of excellence and creep resistant famous.The visible light transmissivity of PC resin is more than 90%, and heat decomposition temperature is high, has excellent electrical insulating property, be widely used in machinery, automobile, space flight and aviation, building, electronics, electrically, the numerous areas such as office and household supplies.
In order to increase the flame retardant resistance of polycarbonate film, usually add fire retardant, what traditional fire retardant often adopted is halogen containing flame-retardant, although most of halogen containing flame-retardant addition in fire retardation PC material is few, flame retardant effect is remarkable, but produces more smog and poisonous, corrosive gases when burning, and causes serious environmental pollution.
Usually and one or more synergists using.These synergists have the mixture, aluminium hydroxide (ATH) etc. of II A race organic metal salt (as Magnesium Stearate), ammonium polyphosphate (PPA) and tetramethylolmethane.They can be polymerized with base material, again can with oozing property mutually, and the generation of layer of charcoal can be promoted, and then stop the formation of cigarette and the development of flame.For being added with filler and unloaded polyolefine, because silicone polymer during burning can form layer of charcoal with them, so its oxygen index can be improved, flame propagation velocity can be reduced again.No matter copper silicon polymkeric substance is used as additive or the composition as multipolymer, the low temperature impact strength of organic plastics all can be improved.Due to inertia and the stability of silicone resin, and extremely low second-order transition temperature (being-54 ~ 87%), even if so it still can keep its elasticity under being in high temperature or low temperature for a long time.In some cases, silicone resin can also reduce polyolefinic second-order transition temperature, and this illustrates that silicone resin is compatible with polyolefin substrate.
