Machine printing render silica gel used for dot color contrast and preparation method thereof

Abstract

The invention discloses machine printing render silica gel used for dot color contrast. The machine printing render silica gel comprises the following components in parts by weight: 90 to 110 parts ofan A component of the machine printing render silica gel used for dot color contrast and 8 to 11 parts of a B component of the machine printing render silica gel used for dot color contrast; in termsof parts by weight, the A component of the machine printing render silica gel used for dot color contrast consists of the following raw materials: 100 parts of machine printing render silica gel baserubber used for dot color contrast, 10 to 20 parts of 10000cs vinyl silicon oil, and 0.3 to 0.8 part of 3000ppm platinum catalyst. The invention also discloses a preparation method of the machine printing render silica gel used for dot color contrast. The product can guarantee 24h operation time at the temperature of 60 DEG C or more, can be quickly cured at the temperature of 130 DEG C, and canbe used for an extremely elaborate dot color contrast technology and a silk-screen printing technology for a gauze of more than 250 meshes, so that a more delicate pattern is formed. The operation time is longer at a high temperature condition, and excellent effects of continuous production and no gauze blockage can be realized.

Description

technical field [0001] The invention relates to silicone rubber, in particular to a machine-printed base silica gel for dot color contrast, and a preparation method of the machine-printed base silica gel for dot color contrast. Background technique [0002] In the prior art, the machine-printed silica gel used on the elliptical machine can only guarantee a long operation time under the condition of 50 degrees Celsius. If the temperature is higher than 50 degrees Celsius, it will be cured in a short time and the operation time is short. [0003] Moreover, these existing machine-printed silica gels can only be used in ordinary screen printing processes, and cannot be used in the dot-contrast process where fine patterns are required for forming patterns. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a machine-printed base silica gel for dot color contrast in view of the above problems. [0005] Another object of the present invention is...

Problems solved by technology

[0002] In the prior art, the machine-printed silicone used on the elliptical machine can only guarantee a long operating time at 50 degrees Celsius. If the temperature is higher than 50 degrees Celsius, it will solidify in a short time and the operating time is short.

[0003] And these existing machine-used printing silicone can only be used in ordinary screen printing process, and cannot be used in the dot color contrast process that requires fine pattern forming
