Description

A kind of explosion-proof lamp and preparation method thereof of color inhibition nanostructure
Technical field
The present invention relates to a kind of explosion-proof lamps and preparation method thereof of color inhibition nanostructure.
Background technique
The development that modern society's material is advanced by leaps and bounds, the high molecular materials such as polyurethane, because its excellent performance is answered extensively For replacing all various aspects such as conventional oil-based coating and closed protective, it is known as the fifth-largest plastics.And yield has significantly increasingly The trend of growth.
Polyurethane can have multiple application, durings PU leather, foaming agent, adhesive, sealer, fiber etc. is made.This is specially Benefit is especially concerned with reaction injection molding technology.(Reaction Injection Molding, referred to as " RIM ").RIM is benefit Make two kinds of monomer materials mixed at high speed in minimum space with impacting with high pressure, gun slot sprayed by high pressure, impinge upon by Spray a technology of body surface.The technology makes the expansion of the application scenarios of polyurethane sharply, but with the accumulation of time, cruelly Expose many problems.A very big problem is: by the environmental attack of outdoor ultraviolet light, material can produce after a period of time Raw xanthochromia.The reason of xanthochromia be ultraviolet light and other easily cause the factor of oxidation easily to make phenyl ring (or the α of ether-containing key-carbon is former Son) on a hydrogen by oxygen to replace, when replace occur after.The performance of macro object is xanthochromia.
The different factors such as invasion, the heating degree of number, oxygen because of environment such as ultraviolet light, xanthochromia simultaneously anisotropically occur On the sample entirely covered by material, by must the time one fritter of a fritter, Huo Zheyi indefinitely can locally occur The surface for being presented on material of one dot of dot.Extremely influence appearance.As the extension of time can cause shadow to the performance of material It rings.
Material at this stage improves uvioresistant and improves resistance to combustion, will cause very big influence to the intensity of material, just as Impurity is the same in material, and anti-effect can be played to the overall performance of material, therefore designs a kind of intensity height, and the color inhibition time is long New material be our target.
