Description
The present invention relates to transparent polymer material of a kind of high comprehensive performance and preparation method thereof.
As everyone knows, organic transparent polymer material has lightweight than inorganic transparent material (as silex glass), high-strength, high tenacity, and numerous advantages such as easy processing, it is low also to exist surface hardness certainly, and water-intake rate is big, shortcomings such as poor heat resistance.Therefore how to improve the thermotolerance and the surface hardness of transparent polymer material, reduce the main direction of studying that water-intake rate and the further toughness that improves material have just become transparent polymer material.Transparent polymer material as optical mirror slip also needs high specific refractory power simultaneously, to reduce the thickness of eyeglass.
Transparent polymer material the most commonly used at present mainly contains acrylic resin, polycarbonate, CR-39 resin (allyl group Diethylene Glycol polycarbonate) and polystyrene etc.Yet these resins all respectively have its advantage and deficiency.As polymethylmethacrylate (PMMA) good in optical property, easy molding moulding and mechanical workout, but its poor heat resistance, easy hygroscopic deformation, surface hardness is low, simultaneously must careful controlled polymerization heat during polyreaction etc.CR-39 is a kind of heat cured transparent polymer material that is widely used in ophthalmic lens, and it has numerous advantages, do not change as eyeglass lens power with temperature, and excellent cutting, cycling processability, but its curing molding shrinking percentage is big, specific refractory power also not too high (1.50).As previously mentioned, though the report of many relevant transparent polymer material products is arranged both at home and abroad, but these products are based on transparent polymer material mostly in the application in a certain field or to the improvement of a certain performance of material itself, indivedual performances of these materials may be comparatively outstanding, and its over-all properties is not the best, and can not carry out the adjusting of performance by the difference of using object.As a kind of JD plastics that are named as of Chinese patent (patent No. is 87104153) report, have higher transmittance and higher specific refractory power, but during its moulding set time longer, and the easy isomerization of molecule under illumination.And a kind of multipolymer that contains halo group and phenyl ring with high index (about 1.60) of report in the United States Patent (USP) 4360653, but the thermal characteristics of this material is not good.
The object of the invention provides transparent polymer material of a kind of high comprehensive performance and preparation method thereof, and the processing condition of kind, proportioning and processing that the performance of this class transparent material can be by changing raw material are regulated.
Transparent polymer material of the present invention is a kind of carbamate macromonomer and styrene copolymerized system of forming by acrylate ended, and this macromonomer structure is as follows: R " and COO-NH-(R-NHCOO-R ' COO-NH)
n-R-NHCOO-R "
Wherein R " is CH
2=CHCOO (CH2)
m
Transparent polymer material preparation method of the present invention may further comprise the steps: (following all with mol ratio calculating)
Step 1: macromonomer synthetic
With 1 mole of vulcabond and 0.5 mole of dibasic alcohol (dibasic alcohol can not add yet) stirring reaction after 0.5 hour in reactor, add 1 mole of hydroxy acrylate (if dibasic alcohol does not add, need with 2 moles of hydroxy acrylates), reacted again 0.5 hour, add and calculate 1/2 to 3/4 of required vinylbenzene weight by a certain percentage, and adding 0.01% dibutyl tin laurate of vulcabond weight simultaneously, stirring reaction is about 1 hour.
Step 2: performed polymer synthetic
In above-mentioned reaction system, add the vinylbenzene under the residue that contains 0.1% (weight ratio of total overall reaction thing) azo, two isonitrile again, stir, reaction poured in the mould for preparing in advance after 0.5 hour in 50 ℃ water-bath.
Step 3: curing reaction
Place the good mould of casting the baking oven that is not higher than 100 ℃ (being everlasting 60 ℃ to 80 ℃) to carry out cross-linking and curing reaction 5 to 7 hours (60 ℃ solidified 7 hours down, and 80 ℃ solidified 5 hours down).The cooling die sinking gets a hyaline smooth plastic plate.
Vulcabond of the present invention has tolylene diisocyanate (TDI), 4,4 '-diphenylmethanediisocyanate (MDI), 1.5-naphthalene diisocyanate (NDI), 1.6-hexamethylene diisocyanate (HDI), xylylene diisocyanate (XDI), dicyclohexyl methane diisocyanate (HMDI), isophorone diisocyanate (IPDI).
Hydroxy acrylate of the present invention has Hydroxyethyl acrylate (HEA), Propylene glycol monoacrylate (HPA), hydroxyethyl methylacrylate (HEMA), Rocryl 410 (HPMA).
Dibasic alcohol of the present invention has ethylene glycol, butyleneglycol, pentanediol, ethylene glycol, nonanediol, decanediol, polyester diol, poly-beta-lactam dibasic alcohol, polyoxyethylene dibasic alcohol and polyoxytrimethylene dibasic alcohol.
Transparent polymer material of the present invention and preparation method thereof has following outstanding advantage:
1, because vinylbenzene is the thinner of prepolymerization reaction in initial reaction stage, and is a combination participation reaction of reaction when solidifying, makes reaction all have good operability from start to finish like this, be particularly conducive to industrial production.
2, the used main raw material vinylbenzene of the present invention is cheap, so the cost of end article is also lower.
3, owing to adopted the method for macromonomer and small molecule monomer copolymerization, the chemical bond ratio that can react in the system is little, so cure shrinkage little (less than 2%).Solidification rate is fast simultaneously, and level of response is even, and exothermic heat of reaction is little.These provide advantageous conditions for making the casting type transparent polymer material, and therefore prepolymerization reaction and curing reaction time are all shorter in the present invention, and temperature of reaction is low, and reaction conditions is not harsh yet, helps suitability for industrialized production.
4, the high comprehensive performance of material, surface hardness, shock strength, performances such as water-intake rate all improve a lot, and the specific refractory power of material also obviously improves simultaneously.
5, owing to can select different vulcabond for use, dibasic alcohol and hydroxy acrylate, and styrene content can be regulated arbitrarily in copolyreaction, and so just can be according to the special requirement adjusting of practical application and the performance of control material.Particularly select different kindliness dibasic alcohol to make chainextender, can make the different material of performance.The synthetic blended macromonomer of dibasic alcohol that can also select simultaneously two or more can more critically be regulated material property so again with styrene copolymerized.
The following examples are to further specify of the present invention, rather than limit the scope of the invention.
