Polyurethane elastic process paint formula and preparation method

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".

[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, mice, mobile phones, car joysticks, microphones, handles and other products; The existing "elastic paint" not only requires drying, long baking time, high baking temperature, wasting energy and time, but also the "paint film" after painting or spraying is hard, has poor hand feeling and poor quality etc., there is still a narrow range of use, which cannot meet people's higher requirements for paint and the demand for developing new products and improving product quality and grades.
