Glue roller squeegee oil for large size ceramic tile otter board printing

Abstract

The invention belongs to the squeegee oil category of ceramic industry, in particular to rubber roll squeegee oil for large-scale ceramic tile screen printing. The rubber roll squeegee oil is a mixture which consists of the following components by weight: 45 to 60 parts of glycerol, 30 to 45 parts of polyether polyol, 7 to 18 parts of polymer and 0.2 to 5 parts of initiator; and the characters are as follows: the rubber roll squeegee oil is colorless or slightly yellow translucent body; the viscosity is 110 to 130Mpa question mark S; the density at 20 DEG C is 1.040 to1.060; the pH value is 6 to 8, and the freezing point is minus 30 DEG C. The high polymer refers to acrylic acid, acrylamide or polyethylene glycol. The initiator refers to sodium peroxide, amine peroxide or potassium peroxide. The rubber roll squeegee oil can be applicable to the printing needs of ceramic walls and floor tiles with various specification and large format; the specific gravity and the thickness can be adjusted. The rubber roll squeegee oil has good suspension and dispersion properties, no delamination during the placement, performances of keeping moisture, lubrication, penetrating screen, cooling screen, anti-static, and the like and strong applicability. Printing glaze slurry which is prepared by the rubber roll squeegee oil has good liquidity, low viscosity and convenient application, the bonding force of a color agent on a green body is increased, and a printed pattern is bright and clear.

Description

technical field [0001] The invention belongs to the category of printing ink in the ceramic industry, in particular to a rubber roller printing ink for screen printing of large-sized ceramic tiles. Background technique [0002] Rubber roller printing ink is a special printing ink used on roller or rubber roller printing machines. It has the characteristics of low viscosity, good moisture retention, good lubricity, cool net, good net penetration, and excellent high suspension and dispersion performance. With the demand of the market, the specifications of ceramic wall and floor tiles are getting larger and larger, and the existing rubber roller inks for screen printing of large-sized ceramic tiles are basically imported products from abroad, and the existing domestic products of rubber roller inks either contain more Sodium and magnesium ions, resulting in ash content of more than 5%, the performance can not meet the requirements; or can not meet the customer's requirements f...

With the demand of the market, the specifications of ceramic wall and floor tiles are getting larger and larger, and the existing rubber roller inks for screen printing of large-sized ceramic tiles are basically imported products from abroad, and the existing domestic products of rubber roller inks either contain more Sodium and magnesium ions, resulting in ash content of more than 5%, the performance can not meet the requirements; or can not meet the customer's requirements for a variety of mimeograph products; there are some deficiencies in quality, or the lack of specific gravity and density, Placed for 2-3 days, it is easy to precipitate and stratify, resulting in color difference; or poor lubricity and mesh penetration; or the bonding force of glaze slurry to the green body is weak, and the surface cleanliness of ceramic wall and floor tiles after firing is poor, with unevenness, pinholes or patterns Not clear enough, poor brightness
