Abstract
The invention relates to soluble polyurethane finished enamel, which consists of a composition A and a composition B, wherein, the composition A by weight portion comprises 40 to 80 portions of soluble hyperbranched polyurethane resins, 0.5 to 2 portions of antifoaming agent, 0.5 to 2.0 portions of flatting agent and 5 t0 20 portions of deionized water; the composition B is liquid terminal hydroxyl hyperbranched polymers; and the mass ratio between the composition A and the composition B is 1 to 0.25-0.35. During the preparation process of the finished enamel, no organic solvent is required to be used, thereby the organic solvent pollution of the prior solvent finished enamel is completely overcome and the environmental protection in a real sense is realized. The adoption of the hyperbranched polymers not only can reduce the viscosity of a paint enamel system, improve the solid content and accelerate solidification but also can obviously increase the shock strength and the adhesion of solidified products. After the finished enamel is coated on the surface of an article, a paint film is bright and plump, and tough and abrasion resistant, and has good gloss and color retention. Moreover, the soluble polyurethane finished enamel also has the advantages of simple manufacturing technique, low production cost and so on.
Description
Technical field
The invention belongs to the finished enamel field, particularly relate to a kind of water-soluble polyurethane finished enamel.
Background technology
Finished enamel is meant and is used to be coated with the enamel paint that is contained in article, equipment surface that it has good decoration effect and defencive function to article, the equipment of application.Through the application of finished enamel, iron and steel is difficult for getting rusty, and can prolong the work-ing life of article, equipment.In our various fields in life, use finished enamel invariably in a large number, as the fields such as application of the decoration in the application of the manufacturing of furniture, building, house, vehicular traffic, dynamo-electric equipment, instrument etc.Along with the progress of constant development of economy and society, people are more and more higher to the requirement of product, the electronic product external coating wants not only that outward appearance is beautiful, fast drying, more require VOC to discharge little, no triphen, heavy metal content will meet environmental protection and ROHS standard.
Finished enamel develops to the water-soluble environment protective type from initial containing benezene solvent-borne type, no benzene kind solvent type gradually, as application number is just containing benezene solvent not of 200610040431.6 Chinese invention patent " environment-friendly polyurethane surface lacquer enamel ", and only contains 5～15% N-BUTYL ACETATE; The patent of invention that application number is 200710135161.1, name is called " environmental protection acrylic polyurethane two-pack finished enamel " has been used 3～7% 1-Methoxy-2-propyl acetate and 5～15 methylcarbonate organic solvents equally, on the one hand, these organic solvents will evaporate in the enamel paint solidification process and pollute to environment, on the other hand, then can increase production cost, particularly, more need energy-conserving and environment-protective, reproducible material product as an alternative in today of oil equal energy source shortage.In view of improving constantly of the demand of national environmental protection, European ROHS standard and people's environmental consciousness, under such historical background, needing badly provides a kind of finished enamel that does not contain the truly environmental protection of organic solvent.
Summary of the invention
Technical problem to be solved by this invention provides a kind of water-soluble polyurethane finished enamel of environment-friendly type, and this finished enamel does not contain organic solvent, VOC free discharging.
For solving above technical problem, the present invention takes following technical scheme:
