Description
Technical field
The present invention relates to technical field of composite materials, and in particular to a kind of preparation method of organo-mineral complexing transparent material
And preparation method thereof.
Background technique
High polymer transparent material is due to light transmittance height, and relative density is small, and insulation performance is good, with certain intensity and tough
Property, it is easily broken not as unorganic glass, processing and forming technology is fairly simple, and transparent plate, pipe, stick and each can be made
Kind object cover, vessel, optical mirror slip, see-through model etc.；The disadvantage is that low using temperature, surface hardness is small, intolerant to abrasion, by larger
Stress or certain solvent actions when can generate micro-crack, this micro-crack dodges silver-colored light in the case where light shines, therefore claims crazing, sternly
The crazing of weight will affect transparency.In addition, being influenced in long-term use by the environmental conditions such as ultraviolet light, damp and hot, it may occur that drop
Solution reaction, makes surface turn to be yellow.
Summary of the invention
After the technical problem to be solved by the present invention is to overcome high polymer transparent materials in the prior art using being for a period of time
The defect of surface jaundice, provides a kind of preparation method and preparation method thereof of organo-mineral complexing transparent material.
In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions:
A kind of preparation method of organo-mineral complexing transparent material, by 100 parts of polymethyl methacrylate, 15~20 parts thoroughly
Bright polyurethane, 0.8~1.0 part of 20~30 polyethylene silica, 0.6~0.8 part of organo montmorillonite, initiator 0.1~
0.18 part and 0.1~0.2 part of light stabilizer sequentially adds in blender, and resin compound, vacuum defoamation are obtained after high speed dispersion
It stands naturally to room temperature afterwards, sealed package to obtain the final product.Preferably, by 100 parts of polymethyl methacrylate, 18 parts of transparent poly- ammonia
Ester, 0.8~1.0 part of 24 polyethylene silica, 0.6~0.8 part of organo montmorillonite, 0.15 part of initiator and light stabilizer 0.1
~0.2 part sequentially adds in blender.
Further, the production viscosity of mixture is 16000~19000CPa.S.
Further, the initiator is 184, light stabilizer 770.
Further, the organo montmorillonite is by cetyl trimethylammonium bromide, octadecyl trimethyl chlorination
Organic montmorillonite obtained by ammonium or didecyl Dimethy ammonium chloride.
Further, montmorillonite is dispersed in the suspension that 1-2% is made in distilled water, ten that w/v ratio is 1-3% are added dropwise
Six alkyl trimethyl ammonium bromide solution, octadecyltrimethylammonium chloride solution or didecyl Dimethy ammonium chloride solution rise
Temperature is filtered, is washed with distilled water to 85-95 DEG C and constant temperature 4-6h, until detected with silver nitrate to no bromide ion, it is dry to perseverance
Weight is to get modified organo montmorillonite.
The beneficial effects obtained by the present invention are as follows being: the preparation method of organo-mineral complexing transparent material of the invention not only has
There is the higher transparency, and general montmorillonite is replaced using modified organo montmorillonite, triggers the initiation monomer polymerization of multiple spot
The agglomeration of point, mixing material is high, therefore the transparency of material is high, and the toughness of material is strong, and ageing resistance is strong.
