Embodiment 1

[0019] A production process of a polyurethane moisture curing agent macromolecular material comprises the following steps: 1) Input raw materials: add toluene diisocyanate, butyl acetate, fatty acid resin, polyester polyol in a ratio of 6:4.5:1:1.5, stir, Raise the temperature to 66°C, keep it warm for 2 hours, and then add antioxidant; 2) Cool down and keep the temperature at 54°C, add one-half of the total amount of trimethylolpropane, and then add the remaining half after 20 minutes The amount of trimethylolpropane, raise the temperature to 64°C within 25min, and keep it warm for 2h; 3) keep it at 64°C, add one-half of the total amount of polyether polyol, keep warm for 30min, and then add the remaining half A certain amount of polyether polyol continues to react for 1.5h, while adding polyether polyol each time, add butyl acetate; 4) cool down and control the temperature to keep at 55°C, add diethylene glycol, and simultaneously add butyl acetate Ester, heat preservation r...

Abstract

The invention discloses a polyurethane moisture curing agent high polymer material and a production process thereof. The high polymer material comprises, by mass, 590 to 610 parts of toluene diisocynate, 530 to 550 parts of butyl acetate, 90 to 110 parts of fatty acid resin, 140 to 160 parts of polyester polyol, 4 to 5 parts of an antioxidant, 95 to 105 parts of trimethylolpropane, 390 to 410 parts of polyether polyol, 40 to 50 parts of diethylene glycol, 8 to 12 parts of n-butyl alcohol, 4 to 5 parts of an organic silicon type flatting agent, 2.5 to 3.5 parts of a polymer type flatting agent and 0.8 to 1.2 parts of a polymer type defoaming agent. After the polyurethane moisture curing agent high polymer material is sprayed, a spectacle frame does not need to be subjected to heat preservation baking, the curing effect can be achieved only by keeping a room wet, the hardness, glossiness, brightness, leveling degree and adhesive force of a sprayed film layer can be improved, the product performance is improved, and the market competitiveness is enhanced.

Description

technical field [0001] The invention relates to the field of eyeglass frame coating, in particular to a polyurethane moisture curing agent polymer material and a production process thereof. Background technique [0002] Polyurethane moisture curing agent (glasses gold oil) is a kind of moisture curing agent, which is an attachment sprayed on the spectacle frame and can be sprayed into various colors. With the development of time, Europe, America, Southeast Asia and other places, as well as Chinese people, have increased their environmental protection requirements and quality performance requirements for glasses year by year, posing great challenges to the coating process of traditional spectacle frames. [0003] Traditional coatings and production processes not only need to be baked at no lower than 65-75°C for more than seven or eight hours after spraying, but also have certain defects in hardness and adhesion. Contents of the invention [0004] In order to solve the abo...
