Description
Technical Field
The invention relates to the field of high polymer materials, and particularly provides quaternary phosphonium salt modified mercaptan with autocatalysis activity, a preparation method and an ultrahigh-refractive-index optical resin material prepared from the quaternary phosphonium salt modified mercaptan.
Background
With the development and intensive research of polyurethane resin materials in recent years, optical resin lenses with refractive indexes of 1.60-1.67 are popular in the market, and in order to meet the higher pursuit, namely, resin lenses with ultrahigh refractive index, lighter weight and clearer imaging become the focus of attention of people, the refractive index of the optical resin material cured by using the episulfide compound can reach more than 1.70, and the requirements of people are met.
However, the episulfide compound of this system has a high curing rate and is difficult to control, and causes optical problems such as uneven texture and cloudiness, and most of the systems use an amine, a quaternary ammonium salt, a quaternary phosphonium salt, a tertiary sulfonium salt, a secondary iodonium salt, a phosphine compound, and the like as a catalyst for curing. The salts have high toxicity and have neurotoxicity after long-term contact, such as triphenylphosphine is easy to decompose when heated and releases toxic phosphine and POXAnd (4) smoke.
The reaction rate of the phosphine compound is smaller than that of other catalysts in view of the curing rate. Although there are many methods for improving this problem, such as a method of measuring the haze of a polymer composition at 50 ℃ for 7 days as in "composition for optical material and method for producing the same and optical material obtained from the composition for optical material", the cloudiness phenomenon is eliminated, which is time-consuming and greatly increases the time cost; the novel episulfide compound and optical material composition does not need refrigeration, and the epoxy compound with halogen group is added, so that the white turbidity phenomenon can be improved, but the yellowing resistance effect is poor; the problem is improved by adding benzyl halide into the composition for optical materials, but the benzyl halide has high toxicity and is not a green and environment-friendly process.
Therefore, how to overcome the above-mentioned drawbacks of the prior art is a problem to be solved.

the temperature-raising program is adopted for the first curing, so that the polymerization reaction can be ensured to slowly open the ring and fully perform the chain growth reaction at a relatively low-temperature stage, and meanwhile, enough temperature conditions are provided at a crosslinking stage to realize optimal degree crosslinking;
the quaternary phosphonium salt modified mercaptan directly participates in the reaction during the first curing, is dispersed in the system more uniformly, is more uniformly mixed with various raw materials, and is more uniformly reacted; compared with the initiator in the prior art, the initiator used is salt which can be dissociated in the whole system to cause nonuniformity of the system, fast partial curing and slow partial curing, so that nonuniformity of the texture of the lens after the first curing is caused, the finished product rate is low, the use is influenced, and subsequent processing cannot be carried out;
preferably, the temperature of the second curing in the step b) is 90-110 ℃, and the time is 1.5-3 h; more preferably, the temperature is 100 ℃ and the time is 2 h;
