Abstract

The invention discloses a paint technology, in particular to a 'polyurethane elastic process paint' formula and a preparation method; the formula of polyurethane elastomer is used in the paint formula and each component is measured and prepared to produce paint according to a certain proportion. The 'paint' comprises the following components: component A: 30 parts of diacetone alcohol, 30 parts of butyl acetate, 30 parts of xylene, 10 parts of cyclohexanone, 28-35% of elastic resin, 0.9-8.1% of elasticator, 5-6% of OK520 matt powder, 0.9-3.1% of flatting agent, 1.8-2.2% of feel agent, 1-2.2% of drier and 0-5.5% of elastic powder 5070 D; component B: 100% of firming agent 3390; component C: 50 parts of toluene and 50 parts of butyrin. The 'paint' is characterized in that when the 'paint' is coated on the workpiece, after air drying or baking, the 'paint' can turn up with a magical effect that the paint film has the springy feel like human skin and fine hairs. The 'paint' has mild texture, is a modern innovative paint and fills the technology gap in China and abroad.

Description

Technical field: [0001] The invention relates to a paint technology, in particular to a formula and a preparation method of "polyurethane elastic craft paint". Background technique [0002] Paint is an indispensable decorative material in modern life. The application of paint gives people a sense of beauty, touch, and even colorful color vision; it gives the painted object beauty, beauty, decoration and protection; and paint is One of the coatings, paint refers to the "dry paint film" formed by painting and spraying on the surface of an object, which is naturally dried in the dry environment of nature or dried in the sun or air-dried or baked to make the object beautiful. And get protection, or form a kind of film-forming substance with other special functions on the surface of the substance. [0003] The traditional "elastic paint" is a kind of paint, which is mainly used to spray on ABS, PC or other substrates, and is only suitable for the coating of computer keyboards, m...
