B component:
Described polyether glycol DDL-1000D is molecular weight to be 1000 functionality be 2 polyether glycol, by Zibo moral, this polyethers believes that federal chemical Industrial Co., Ltd produces.
Described polyisocyanates is that VoranateT-80, Dow company produces.
Polyether glycol DEP-330N is molecular weight to be 4800 functionality be 3 polyether glycol, by Zibo moral, this polyethers believes that federal chemical Industrial Co., Ltd produces.Use two kinds of polyethers with the use of, resulting product transparency is higher.
Described UV light absorber is UV-531, and Jiangsu is thought this Chemical Co., Ltd. big and produced.
Described vulcanizing agent is dimethythiotoluene diamine, and Zhangjiagang Ya Rui Chemical Co., Ltd. provides.
Described softening agent is dibutyl phthalate, and Yingkou Tianyuan chemical industry provides.
The preparation method of urethane eyepiece of the present invention, step is as follows:
(1) preparation of component A: polyether glycol DDL-1000D is warming up to 110-120 DEG C of vacuum hydro-extraction 2-2.5 hour, be cooled to less than 50 DEG C and add polyisocyanates, be warming up to 80-85 DEG C of reaction after 2-3 hour, obtain performed polymer, be cooled to less than 50 DEG C to stir, seal for subsequent use;
(2) preparation of B component: by for subsequent use for the sealing in 20-22 minute of polyether glycol DEP-330N, UV light absorber, vulcanizing agent and softening agent mix and blend;
(3) coat in the mould of releasing agent by pouring into after A, B component mix and blend 10-15 second, 80-85 DEG C of heated die 5-10 minute, i.e. obtained finished product after the demoulding.
The NCO% of the performed polymer described in step (1) is 2-9%.
Releasing agent described in step (3) is for hearing the AK-T14 elastomerics releasing agent that general chemistry provides in Shanghai.
The goggle that the present invention adopts polyurethane material to develop once machine-shaping, simple to operate, with low cost, product material is softer, comfortable wearing, the advantage such as easy to carry, safe.The present invention adopts polyether-type to build elastomerics, and hardness is adjustable, adopts dimethythiotoluene diamine (DMTDA) to make vulcanizing agent, takes into account transparency and tensile property, have the advantage that cost is low, product performance are safe and reliable.
The present invention compared with prior art, has following beneficial effect:
(1) urethane eyepiece of the present invention, its cost is lower, simply easy to operate;
(2) the product once shaped of using the present invention to prepare, greatly reduces labour cost;
(3) goods good integrity of the present invention, safety and comfort, light transmission are good, easy to carry.
