Problems solved by technology

[0002] At present, the common relatively cheap goggles are compound glasses that use soft plastic as the frame and hard polyvinyl chloride (PVC) as the lens. This kind of goggles requires manual assembly and low cost, so the workmanship is poor. , the connection between the two materials is not good, there is a large gap, which causes a great safety hazard to the user, and the wearing comfort is poor
The more high-end products are mostly polycarbonate resin materials (PC). Although this kind of product has higher strength and better light transmission, the price of raw materials is higher and the processing temperature is higher (above 200°C), so the price is higher. And because the material is hard, it can be carried unchanged

Embodiment 1

[0029] The composition of raw materials is as follows:

[0030] A component:

[0031] Polyether polyol DDL-1000D40kg

[0032] Polyisocyanate T-8010kg

[0033] B component:

[0034]

[0035] The preparation method is as follows:

[0036] (1) Preparation of component A: heat polyether polyol DDL-1000D to 110°C for 2 hours in vacuum dehydration, cool down to below 50°C and add polyisocyanate, heat up to 80°C and react for 2 hours to obtain a prepolymer. The NCO% of the polymer is 2%, the temperature is lowered to below 50°C, stirred evenly, and sealed for later use;

[0037] (2) Preparation of component B: Mix and stir polyether polyol DEP-330N, ultraviolet absorber, vulcanizing agent and plasticizer for 20 minutes and seal it for later use;

[0038] (3) Mix and stir components A and B for 10 seconds, pour them into a mold coated with release agent, heat and press the mold at 80°C for 5 minutes, and the finished product is obtained after demoulding.

Abstract

The invention belongs to the technical field of polyurethane products, and particularly relates to polyurethane goggles and a preparation method thereof. The polyurethane goggles are prepared from a component A and a component B, the component A is prepared from, by weight, 40-80 parts of polyether polyol DDL-1000D and 10-40 parts of polyisocyanates, and the component B is prepared from, by weight, 20-60 parts of DEP-330N, 0.01-0.2 part of ultraviolet light absorber, 2-15 parts of vulcanizing agents and 5-30 parts of plasticizer. The polyurethane goggles are low in cost, and convenient and easy to operate. The prepared product is formed at a time, and labor cost is greatly reduced. The product is good in integrity, safe, comfortable, good in light transmission and convenient to carry.
