Abstract

The embodiment of the invention discloses a cleanable pigment capable of being applied to silicone rubber and not prone to falling off and a preparation method of the cleanable pigment, and belongs to the technical field of pigments. The pigment is prepared from water, propylene glycol, titanium dioxide, acrylic resin, polymethacrylate, polyether sulfonate, branched chain sodium alkyl benzene sulfonate, fatty alcohol-polyoxyethylene ether, fatty alcohol-polyoxyethylene ether carboxylate, nonylphenol polyoxyethylene ether, secondary alkyl sodium sulfonate, polyethylene glycol and triethanolamine as raw materials. The pigment can be applied to silicon rubber, and has the characteristics of flexibility, difficulty in falling off and capability of being competent for the flexibility of the silicon rubber after being solidified. The silicon rubber is not dyed and can be repeatedly used after the pigment is cleaned, and the cost for purchasing a large number of silicon rubber substrates during silicon rubber painting is saved. The pigment fills the blank of pigment for silicon rubber, and has a wide market prospect.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of pigments, in particular to a pigment that can be painted on silicone rubber, is not easy to fall off and can be cleaned, and a production method thereof. Background technique [0002] Silicone rubber refers to the rubber whose main chain is composed of silicon and oxygen atoms alternately, and there are usually two organic groups attached to the silicon atoms. Silicone rubber is divided into high-temperature silicone rubber and room-temperature silicone rubber. High-temperature silicone rubber is mainly used to manufacture various silicone rubber products, while room-temperature silicone rubber is mainly used as adhesives, potting materials or molds. Due to the low surface energy of silicone rubber, it is difficult to spread the prepared coating on its surface, and the adhesion effect is poor. [0003] At present, there are protective inks coated on silicone rubber on the market...
