Description

A kind of anti-dazzle fire-resistance polycarbonate and preparation method thereof

Technical field

A kind of anti-dazzle fire-resistance polycarbonate of the present invention and preparation method thereof belongs to the fire-retardant polycarbonate field, particularly is mainly used in decorating lighting lamp outer cover, artwork, material of construction etc.

Background technology

Polycarbonate, usually be selected as the outer cover material of high-quality lighting, its advantage is: physical strength is maximum in the macromolecular material, have the title of shellproof glue, its high thermal resistance, flame retardant resistance, the transparency, over-all properties such as nontoxic, also be that other macromolecular material is incomparable, though the polycarbonate lampshade has possessed above-mentioned various advantages, but along with improving constantly of people's living standard, people not only are satisfied with the needs of suitability and security, require also more and more higher to comfortableness, ornamental, grade and beautiful enjoyment.

At present, at home and abroad on the market as: museum, hotel, hotel, market, bedroom, garden, gallery, leisure place are used for the outer cover material of decorative lighting light fixture, mainly be ornamental ice glass material, a spot of use plastic material as the decorative lampshade of PC, PMMMA, PS.The production technique of decorative plastic lampshade is, by extruding or the mould shape of injection moulding finishes, no matter extrude earlier machinery, mould, tooling cost with Shooting Technique, the outer cover pattern that only just processes, can only be regularly repeating how much floral designs, not have glittering and translucent, the brilliant flower-shaped artistic effect of ice slush.The moulding of art plastic lamp shade, be to pass through high-temperature fusion, floral designs are made in colored roller bearing through extruding or molding mold cavity typing, on the roller bearing and mold cavity in floral designs, be copied on the finished product, so can not produce random irregular pattern effect comes out, tracing it to its cause is exactly fused plastics fusing point unanimity, and the cooling and shaping unanimity is so the specific refractory power unanimity can not form concavo-convex fluctuating, continuous and irregular beauty " frost flower " decorative pattern.The ice glass that is used for the decorative illumination lampshade, usually also be to finish with the way of Physical Processing technology, natural glass fragment or minitype particle are added transparent cured agent such as unsaturated polyester curing molding, make goods being polished, put in order operations such as base substrate cleaning, paint, stenciling coating after the demoulding, the ice glass printing opacity is opaque, flower shape dim uniqueness, however from not repeating, the pattern as its distinctive fossil makes the people that the sense of back to nature be arranged.Also because of its high temperature resistant, fire-retardant, beautiful and popular centuries, but the friability of the ice glass fatal weakness that is it.
