Anti-fouling and wear-resistant organic silicone coating material for ABS (Acrylonitrile Butadiene Styrene) surface and preparation method thereof

Abstract

The invention relates to an anti-fouling and wear-resistant organic silicone coating material for an ABS (Acrylonitrile Butadiene Styrene) surface. The anti-fouling and wear-resistant organic siliconecoating material is prepared by mixing and reacting the following components in parts by weight: 0 to 30 parts of deionized water, 0 to 40 parts of acidic silica sol, 0 to 10 parts of effective pigment, 20 to 60 parts of methyltrialkoxysilane, 1 to 8 parts of phenyltrialkoxysilane, 0 to 10 parts of tetraalkoxysilane, 0.1 to 3 parts of acidic catalyst, 0.1 to 0.4 part of curing accelerator, 2 to 5parts of adhesion accelerator, 0.1 to 2 parts of antifouling agent, 0.1 to 0.6 part of other functional assistants, 5 to 15 parts of alcohol ether solvent and 10 to 15 parts of ester solvent. After being applied on the ABS surface, the material disclosed by the invention has the advantages of 0 grade adhesion, 1H hardness, static water contact angle of more than or equal to 105 degrees and the like, and remarkably improves the friction resistance, anti-fouling performance as well as short-time high temperature resistance and flame retardancy of an ABS substrate.

Description

technical field [0001] The invention relates to a new high-performance fluorosilicon material, in particular to an organosilicon coating material capable of imparting good antifouling, friction resistance and certain flame-retardant effects to ABS. Background technique [0002] Acrylonitrile-butadiene-styrene terpolymer, referred to as ABS, is a thermoplastic engineering plastic with easy-to-obtain raw materials, good comprehensive performance and low price. It has a good surface gloss and can be electroplated, hot-pressed and bonded. It has been widely used in machinery, electrical, automobile, aircraft and other manufacturing industries. ABS plastics are also widely used in kitchen ceilings, lampshades and toilet showers. to make. [0003] But ABS also has its own drawbacks. First of all, stains easily penetrate into the interior of the plastic through the surface, and its antifouling performance is not ideal; secondly, ABS has low hardness and is easy to scratch. For th...

AI Technical Summary

Problems solved by technology

First of all, most ABS products have a low softening point, and the coating must be screened for more effective curing accelerators; second, ABS is easy to deform, so the silicone wear-resistant and hardened coating coated on the ABS surface must take into account a certain degree of flexibility Third, ordinary silicone hard coatings have poor adhesion on ABS, and new adhesion promotion schemes must be developed

Because of these reasons, there are still few reports on silicone wear-resistant and hardened coating materials for ABS that have real application value.
