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 rubber suitable for laser marking on silicone rubber wires and cables and a preparation method thereof, and belongs to the technical field of silicone rubber materials.Background technique[0002]The existing silicone rubber wire and cable surface marking methods mainly include ink printing wheel printing and inkjet printer printing, but there are high cost of ink consumables, ink solutions have a negative impact on human health, unclear printing, and insensitive fonts. Disadvantages. The laser marking 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, VOC), the fonts are clear and scratch resistant, and the production is efficient and safe. Become the trend and preferred method of silicone rubber wire and cable surface marking. However, if the laser marking and printi...
