Abstract

The invention discloses silicon rubber mixing glue suitable for laser marking on silicon rubber wires and cables and a preparation method of the silicon rubber mixing glue, and belongs to the technical field of silicon rubber materials. The silicon rubber mixing glue suitable for laser marking on the silicon rubber wires and cables is prepared from, in parts by weight, 100 parts of silicone rubber, 40-60 parts of silicon dioxide, 2-10 parts of hydroxy silicon oil, 1-5 parts of dimethyl diethoxysilane, 0.3-0.6 part of stearic acid, 0.5-3 parts of a silane coupling agent, 0.2-1.5 parts of titanium dioxide conductive powder and 0.8-1.5 parts of peroxide bis(2,4-dichlorobenzoyl). The invention also discloses a preparation method of the silicon rubber mixing glue. The silicone rubber mixing glue has excellent physical and mechanical properties and electrical insulation properties, and marks which are marked through laser marking on the silicon rubber wires and cables produced by using the silicon rubber mixing glue have clear fonts, a strong three-dimensional feeling, wear resistance and scuff resistance.

Description

technical field [0001] The invention relates to a silicone rubber compound suitable for laser marking on silicone rubber wires and cables and a preparation method thereof, belonging to the technical field of silicone rubber materials. Background technique [0002] The existing marking methods on the surface of silicone rubber wires and cables mainly include ink printing wheel printing and inkjet printer printing, but there are problems such as high cost of ink consumables, negative impact of ink solution on human health, unclear printing, and not resistant to rubbing, etc. shortcoming. The laser marking and printing method is a non-contact printing process, which will not cause deformation of cable products, does not require ink, does not produce volatile organic compounds (Volatile Organic Compounds, referred to as VOC), the font is clear and scratch-resistant, and the production is efficient and safe. It has become the trend and preferred method for surface marking of sil...
