Antifouling and wear-resistant silicone coating material for ABS surface and preparation method thereof

Abstract

The invention relates to an anti-fouling and wear-resistant organic silicon coating material for ABS surface, which is prepared by the mixed reaction of the following components, and the dosage of each component is as follows: deionized water 0-30, acid silicon Sol 0‑40, effect pigment 0‑10, methyltrialkoxysilane 20‑60, phenyltrialkoxysilane 1‑8, tetraalkoxysilane 0‑10, acid catalyst 0.1‑3, curing accelerator Agent 0.1-0.4, adhesion promoter 2-5, antifouling additive 0.1-2, other functional additives 0.1-0.6, alcohol ether solvent 5-15, ester solvent 10-15. After the material of the present invention is applied on the ABS surface, it has the advantages of adhesion force 0 grade, hardness 1H, static water contact angle ≥ 105°, etc., and significantly improves the friction resistance, antifouling performance and short-term high temperature resistance and resistance of the ABS substrate. burning ability.

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.
