Abstract
The present invention provides optical glass with low thermal conductivity. The optical glass with low thermal conductivity is prepared from polycarbonate and polymethyl methacrylate by addition of 3-9 parts of dioctyl phthalate, 1-5 parts of tribasic lead sulfate, 5-10 parts of aluminium acetylacetonate and 1-5 parts of epoxy vegetable oil. Compared with the prior art, the beneficial effects are as follows: the optical glass is prepared by addition of the dioctyl phthalate, the tribasic lead sulfate, the aluminium acetylacetonate and the epoxy vegetable oil, so that the optical glass has the advantage of good low thermal conductivity.
Description
Technical field
The present invention relates to optical glass field, particularly relate to a kind of optical glass with low heat conductivity.
Background technology
Low heat conductivity is the important indicator weighing optical glass quality, but the low heat conductivity of existing optical glass is generally general.
Summary of the invention
To be solved technical problem is that the defect overcoming prior art to exist, it is provided that a kind of optical glass with low heat conductivity.
The adopted technical solution is that a kind of optical glass with low heat conductivity, including Merlon and polymethyl methacrylate, it is also added into dioctyl phthalate 3-9 part, tribasic lead sulfate 1-5 part, aluminium acetylacetonate 5-10 part, epoxidized vegetable oil 1-5 part.
Compared with prior art, the had the beneficial effect that present invention of the present invention passes through to add dioctyl phthalate, tribasic lead sulfate, aluminium acetylacetonate, epoxidized vegetable oil so that the advantage that this invention has good low heat conductivity.
